To improve + compatibility with old code, the <gfx/gfx.h> header will + automatically import this namespace into the default global one. + This behavior can be turned off by defining the GFX_NAMESPACE + preprocessor symbol. + + o The scripting framework now allows for encapsulation of one syntax + inside another. However, this is experimental, and is likely to + change considerably in a future release. + + o Extended the script interface to support void parsers that throw + exceptions on errors rather than passing return codes. In future, + this will become the default way of writing parser functions. + + o The script_do_xxx() functions formerly defined in <gfx/script.h> + have been removed. They were long ago superseded by the + CmdEnv::do_xxx() methods. + + o Fixed the unitize() method for quaternions, which did not in fact + result in a unit quaternion. + + o Added a small collection of useful color manipulation routines in + <gfx/color.h>. + + o Added an ortho_camera_lookat() function to complement the + longstanding camera_lookat() perspective function. + +in Version 1.0.3 +---------------- + + o When compiling with GCC, warnings are turned on by default. To + compile without warnings, you must use --disable-warnings when + running the 'configure' script. + + o The tests used by the 'configure' script to detect OpenGL headers + were a bit broken. These tests are now much more reliable. + + o The quaternion SLERPing code in previous revisions was incorrect + due to a typo in the code. This problem has been fixed. + + o The file parser provided by <gfx/script.h> now supports the use of + libgzstream. When using the library, the scripting code will + automatically decompress files ending with {.gz, .z, .Z} suffixes. + You must use the --enable-gzstream option when running ./configure. + + o New experimental build files for use with Apple's XCode + development environment are available in the 'xcode' directory. + + o Added functions to <gfx/geom3d.h> for computing the volume + of tetrahedra. + + o The MIN/MAX macros were broken under Cygwin. + + o Fixed up a few miscellaneous compiler warnings. + + o Added an experimental MxBinder class to <gfx/gui.h>. This makes + it fairly painless to bind MxGUI member functions to FLTK callbacks. + + o Moved management of libgfx source code from CVS to Subversion. + + +in Version 1.0.2 +---------------- + + o The MxGUI::snapshot_to_file() method now takes an optional + filename argument. When provided, the code will simply write a + snapshot to this file, rather than presenting the user with a file + selector. + + o The MxGUI::snapshot_to_file() method will now save the alpha + channel of the window, assuming the file format supports that. + (Currently, only PNG and TIFF support alpha channels.) + + o MxGUI OpenGL windows allocate alpha channels (when available). + + o New vector/matrix modules: + + - <gfx/symmat4.h> Symmetric 4x4 matrices; after <gfx/symmat3.h> + - <gfx/vecn.h> Preliminary support for n-D vectors + - <gfx/matn.h> Preliminary support for nxn matrices + - <gfx/symmatn.h> Preliminary support for nxn symmetric matrices + + o Project files for Apple's ProjectBuilder (OS X) are located in the + macos subdirectory. + + o Added checks in the autoconf script for <ext/hash_map> and + <ext/hash_set>, which is where GCC3 chooses to place these + non-standard STL components. + + o The scripting framework now supports a CmdEnv::ignore_command() + method that lets client code specify command names that should be + ignored. This is also available from the input file itself by + using the 'ignore' command. + + o The Baseball-derived classes now have read()/write() methods for + exchanging view information in a textual form. + + +in Version 1.0.1 +---------------- + + o The library should now compile correctly under Visual Studio .NET + (a.k.a Visual C++ 7). + + o The array<> and varray<> templates in <gfx/array.h> have been + removed. Their original purpose was to support legacy code + written in prior to the widespread adoption of STL. The array2<> + and array3<> templates remain, but they are now subclasses of + std::vector<>. + + o Many of the functions in <gfx/geom3d.h> were re-written to by + templatized by vector class rather than by element type. Thus, + they may now be used with any suitable vector type, not just the + TVec3<> template defined in <gfx/vec3.h>. + + o The CmdLine::collect_as_xxx() methods used by the file format + scripting interface now accept an optional 'offset' argument. + This parameter controls at which token the methods start reading. + Their previous behavior was to always begin reading at the first + token on the command line. + + o The script_do_xxx() functions have been replaced with + CmdEnv::do_xxx() methods. The old global functions remain in + place for compatibility, but the new CmdEnv methods should be used + in preference to them. + + o The autoconf process now sets up a symbolic FLTKCONFIG program + name. This is primarily of interest under MacOS X, where the + fltk-config program is used to finalize the build of a GUI + application so that it will launch correctly from the Finder. + The Makefile in the 'test' directory demonstrates the correct use + of this program as a post-build step. + + o Bug fixes: + + - The Raster destructor is now correctly declared as virtual. + + - Certain type declarations have been made more rigorously + correct for proper compilation under GCC 3. + + o A geom4d package has been added that provides functionality + analogous to the geom3d package. + + o A couple of new experimental packages have been added for building + Win32 interfaces with MFC: mfc, wintools, gui-mfc. They are + unfinished, undocumented, and may be unstable. Most users of this + library will want to avoid them. + + +in Version 1.0 +---------------- + + o The documentation is now (mostly) complete and (mostly) + synchronized with the actual code. + + o Trackball & Arcball now share a common Baseball base class. + + o Extensions to the autoconf script to allow for: + + - Automatic configuration under Mac OS X + + - Selection of whether to compile with Cygwin libraries or not + + - Handle differences between FLTK 1.0.x and 1.1.x in the way + that OpenGL code is handled + + o Some minor changes to make the library compile under Mac OS X. + + o Bug fixes: + + - ByteRaster copy constructer faulted due to incorrect size + computation for memcpy(). + +in Version 0.9.3 +---------------- + + o Even more significant changes in the file format scripting package. The + old approach was getting increasingly unmanageable, and the reliance on + magic global constructors for handler registration was proving to be + problematic. + + o Added descriptive interface to vector/matrix types to make + templates easier to write. + + o Vector templates now handle assignment between vectors of + different types (e.g., Vec3 and Vec3f) much more cleanly. + + o New packages to efficiently support symmetric matrix types + (e.g., <gfx/symmat3.h>). + + o Added is_inside_bbox() and clamp_to_bbox() to geom3d package. + + o More complete documentation. + + o Bug fixes in various packages: + + - fixed autoconf script to correctly detect headers + + - Raster class now uses delete[] to match its use of new[]. + + - Scalar multiplication of vectors under VC++ must now use + constants of the same type as the vector elements. This + prevents a tricky bug related to the VC++ template + instantiation. + + +in Version 0.9.2 +---------------- + + o Significant changes to the file format scripting package. All previous + global functions are still available for backwards compatibility, but + you may need to change the definitions of your command handlers. + + o The interface of the <geom3d> package has changed considerably + + - Changed the triangle_* functions to be inlined templated functions. + Before they only worked with Vec3's. Now, they'll work with any + TVec3<T> type. + + - Added a templated compute_bbox() function. + + o Camera and object control has changed a bit + + - The camera_lookat() function in the <gltools> package was putting + both the perspective and lookAt transformations on the Projection + stack. It now correctly puts the perspective on the Projection + stack and the lookAt transformation on the ModelView stack. + + - The Arcball and Trackball manipulators now apply all transformations + to the object, rather than applying rotation to the object and + translation to the camera. + + o Added eigenvalue/eigenvector functions for all matrix types. + + - Because of licensing restrictions, only the 2x2 implementation is + actually present, although prototypes exist for all dimensions. + + o Added a restricted STL-like interface to <array> package. + + o Bug fixes in various packages + + - The 2x2 matrix inversion method was incorrect. + + - read_tiff_image() always returned a 3-channel image. It will now + return an image with the same number of channels as in the file + read. + + +in Version 0.9.1 +--------------- + + o Added a new quaternion package <gfx/quat.h>. [currently undocumented] + + o Added Trackball & Arcball interactive rotation control packages. This + makes it much easier to write applications where the user interactively + spins a model in the window. [currently undocumented] + + o Bug fixes in various packages. + + - Vec3, Vec4 operators for Visual C++ were broken. + - Fixed improper deallocation of array2<> and array3<> objects. + - camera_lookat() incorrectly computed camera location. + + o Applications built on the MxGUI framework can now receive key + press events in the OpenGL canvas area by overriding the key_press() + method. + + +in Version 0.9 +----------- + + This was the initial preliminary release for Fall 2000. diff --git a/debian/fireflies/fireflies-2.08/libgfx/README.txt b/debian/fireflies/fireflies-2.08/libgfx/README.txt new file mode 100644 index 00000000..cffdc13a --- /dev/null +++ b/debian/fireflies/fireflies-2.08/libgfx/README.txt @@ -0,0 +1,71 @@ +------------------------------------------------------------------------ + + libgfx: A Graphics Library + Version 1.1.0 + + Michael Garland <[email protected]> + http://graphics.cs.uiuc.edu/~garland/software/libgfx.html + + Copyright (C) 1999-2005 Michael Garland. + +------------------------------------------------------------------------ + +OVERVIEW +-------- + +The purpose of this library is to simplify the creation of computer graphics +software. Specifically, it is targeted towards cross-platform development +using the OpenGL rendering API and the FLTK interface toolkit. It attempts to +provide facilities which are useful in the majority of graphics programs. It +is derived from the MixKit library I wrote for doing polygonal surface +simplification (see http://graphics.cs.uiuc.edu/~garland/software/qslim.html). + +Instructions on building and using the library can be found in the 'doc' +subdirectory. + + + +CURRENT STATUS +-------------- + +After having gone through multiple pre-release versions, the first +official version (1.0) was released in March 2002. The changes made in +successive 1.0.x series releases were meant primarily to fix bugs and +add new functionality. The current 1.1.x series of releases makes +certain incompatible changes to the code, such as moving headers and +removing support for out-dated mechanisms. + +While the license for this library does not require it, I'd like to +encourage you to contribute bug reports, patches, and whatever +improvements you might come up with to this library. In that way, +others can benefit from your efforts, and you can benefit from the +efforts of others. + + +USAGE TERMS & CONDITIONS +------------------------ + +Permission is hereby granted, free of charge, to any person obtaining a +copy of this software and associated documentation files (the +"Software"), to deal in the Software without restriction, including +without limitation the rights to use, copy, modify, merge, publish, +distribute, and/or sell copies of the Software, and to permit persons +to whom the Software is furnished to do so, provided that the above +copyright notice(s) and this permission notice appear in all copies of +the Software and that both the above copyright notice(s) and this +permission notice appear in supporting documentation. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS +OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF +MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT +OF THIRD PARTY RIGHTS.

It was developed under Windows +NT 4.0, Windows 2000, and RedHat Linux 6. + +<p>This library does make use of the ANSI C++ Standard Library. For +instance, it uses the new <tt><iostream></tt> rather than the +old <tt><iostream.h></tt> package. And it does make some +minimal use of the Standard Template Library (STL). Therefore, it may +not work on older C++ compilers. It is known to work on Microsoft +Visual C++ version 5.0 and above and GNU GCC version 2.9 and above. + +<p><strong>Required</strong> external libraries: +<ul> +<li>The <a href="http://www.fltk.org">FLTK</a> graphical interface toolkit. +<li>An <a href="http://www.opengl.org">OpenGL</a> library +or the <a href="http://www.mesa3d.org">Mesa</a> library. +</ul> + + +<p><strong>Optional</strong> external libraries: +<ul> +<li>The <a href="http://www.libtiff.org">libtiff</a> library for TIFF image +file support + +<li>The JPEG support library from the +<a href="http://www.ijg.org">Independent JPEG Group</a> + +<li>The <a href="http://www.libpng.org/pub/png/">libpng</a> library +for PNG image file support. + +</ul> + + +<h3>For Windows Systems</h3> + + + + +<h4>Visual C++</h4> + +<p>A Visual C++ 6.0 workspace and accompanying project files are +provided in the <tt>vc6</tt> directory. +An older VC++ 5.0 workspace is available in the <tt>vc5</tt> directory. +However, this is no longer in regular use and may be out of date. + +<h5>Manual Build</h5> + +<p>The library can also be built manually using the <tt>nmake</tt> +command line tool.

While many applications may require a fairly sophisticated +interface, there is a large class of applications which can be built with a +very simple interface. The <tt>libgfx</tt> library provides a framework to +ease the construction of such simple interfaces. + +<p>The kind of application interface supported by the GUI framework is +pictured in the following figure: +<blockquote> +<center><img src="gui-layout.gif"></center> +</blockquote> + +The application window consists of three primary components: +<ol> +<li>A menu bar, which is managed by the GUI framework, +<li>An OpenGL canvas window where the application is free to draw its content +and receive user events such as mouse clicks, and +<li>A status bar where the application can print text messages. +</ol> + +<p>The <a href="ex-gui.html">code for the application pictured +above</a> provides a concrete example of using this GUI framework. + +<h3>Creating a GUI Application</h3> + +<p>To begin building your GUI application, you'll need to include the GUI +framework header: +<pre> + #include <gfx/gui.h> +</pre> +The framework itself is packaged as a C++ class named <tt>MxGUI</tt>. +You create your application by subclassing it and overriding various virtual +methods. You can then create a single instance of this class, which will +represent your application. +For consistency, it is recommended that you name +the derived subclass <tt>GUI</tt> and its instance <tt>gui</tt> as in the +following: +<pre> + class GUI : public MxGUI + { + public: + <i>// Application variables and methods</i> + + public: + <i>// Override virtual methods to handle events</i> + }; + + GUI gui; <i>// Create application instance</i> +</pre> + +<p>Programs based using this framework always use the <tt>main()</tt> +procedure as their entry point, <em>even on Windows systems</em>. +Inside this main procedure, you should perform this general sequence of +operations: +<ol> +<li>Initialize global variables and member variables defined in the +<tt>GUI</tt> class. +<li>Call the <tt>gui.initialize()</tt> procedure to parse the command line and +create the application. +<li>Customize the default application by changing labels, adding menus, etc. +<li>Call <tt>gui.run()</tt> to open the application window and begin the event +loop. +</ol> + +<p>The <tt>MxGUI::initialize</tt> method must be called to initialize the GUI +framework. +<pre> + virtual void initialize(int argc, char **argv, + Fl_Menu_Item *layout=NULL, int xw=640, int yw=480); +</pre> +You should pass to it the <tt>argc</tt> and <tt>argv</tt> command-line +variables as passed into <tt>main()</tt>. The framework will take care of +parsing the command-line and calling the appropriate handlers. +The optional <tt>layout</tt> argument can be used to specify an initial menu +structure; the default value of <tt>NULL</tt> directs the framework to use the +default menu layout. +The optional <tt>xw</tt> and <tt>yw</tt> arguments specify the desired width +and height (in pixels) of the OpenGL canvas. + +<h4>Command-Line Processing</h4> + +<p> +The <tt>MxGUI</tt> framework uses the FLTK +<a href="http://www.fltk.org/doc-1.0/functions.html#args"><tt>Fl::args</tt></a> +facility to parse the command line passed to <tt>MxGUI::initialize()</tt>. +For each option on the command line, it invokes the following handler: +<pre> + virtual int cmdline_option(int argc, char **argv, int& index); +</pre> +The <tt>argc</tt> and <tt>argv</tt> values are the complete array originally +passed to <tt>initialize()</tt>. The <tt>index</tt> argument indicates which +element of <tt>argv</tt> contains the current switch being processed. +This <tt>index</tt> variable is passed by reference to allow the handler to +consume additional elements of <tt>argv</tt> by incrementing <tt>index</tt>. +The handler should return <tt>1</tt> if it handled the switch and <tt>0</tt> +otherwise. + +<p>Once all options have been processed, the initialization code invokes the +following handler for each file listed on the command line. +<pre> + virtual void cmdline_file(const char *file); +</pre> +If no files are specified this handler will be invoked with a <tt>NULL</tt> +value. + +<h4>Drawing</h4> + +<p>The <tt>MxGUI</tt> framework uses two virtual methods to control drawing in +the OpenGL canvas. The first of these is: +<pre> + virtual void setup_for_drawing(); +</pre> +This method is called whenever the canvas has been reconfigured. Primarily, +this occurs when the canvas has either just been shown on the screen (e.g., +after creation) or when it has been resized. + +<p>Whenever the canvas needs to be repainted, the framework will invoke the +handler: +<pre> + virtual void draw_contents(); +</pre> +You should override this method and place all your drawing code in it. + + +<h4>Handling Mouse Events</h4> + +<p>Interactive applications will typically want to receive mouse events taking +place on the OpenGL canvas. The framework classifies mouse events into three +types: +<ol> +<li><strong>Button down:</strong> + the user has depressed a mouse button +<li><strong>Button up:</strong> + the user has released a previously depressed button +<li><strong>Drag:</strong> + the user is moving the mouse with a button depressed +</ol> +When one of these events occur, the corresponding event handler will be +invoked: +<pre> + virtual bool mouse_down(int *where, int which); + virtual bool mouse_up(int *where, int which); + virtual bool mouse_drag(int *where, int *last, int which); +</pre> +The <tt>where</tt> argument is a 2-D array containing the pixel location in +the OpenGL canvas at which the mouse was pointing when the event occurred. +The number of the button involved (either 1, 2, or 3) is passed in the +<tt>which</tt> argument. +To simplify drag operations, that event handler is also passed the location of +the <tt>last</tt> received drag event. + +<p>All of these mouse handlers should return <tt>true</tt> if the canvas +should be redrawn in response to the event just handled. If the canvas does +not need to be updated, they should return <tt>false</tt>. + +<h4>Handling Key Presses</h4> + +<p>Key press events can be received through the virtual function: +<pre> + virtual bool key_press(int key); +</pre> +The return value of this function indicates whether the key press event +was consumed by the handler. You should make sure to return +<tt>false</tt> if you do not use the given key, otherwise keyboard +accelerators for the menu bar will no longer function correctly. + +<p>Note that FLTK defines +<a + href="http://www.fltk.org/doc-1.0/enumerations.html#key_values">symbolic + names</a> for non-ASCII keys. You can also query the state of the +modifier keys using the <tt><a href="http://www.fltk.org/doc-1.0/enumerations.html#13_6">Fl::event_state()</a></tt> function. + +<h4>Animation</h4> + +<p>A very simple mechanism for supporting animation is also provided by the +framework. To take advantage of this, first set the <tt>MxGUI</tt> instance +variable +<pre> + float default_fps; +</pre> +to the desired number of frames per second (defaults to 24). The method +<pre> + void animate(bool will); +</pre> +can then be used to start and stop animation. +The system works by setting a system timer to go off every 1/fps of a second. +When that timer goes off, the framework will call the handler +<pre> + virtual void update_animation(); +</pre> +so that the application can update its state appropriately, after which the +framework will invoke the <tt>draw_contents()</tt> handler to repaint the +canvas. Note that this system makes no effort to guarantee a consistent +update rate. + +<p>The default menu bar contains items to toggle animation on and off and to +set the desired <tt>default_fps</tt> value. + + +<h3>The Menu Bar</h3> + +<p>Many GUI applications use menu systems to provide the user control over the +application. By default, the <tt>MxGUI</tt> framework creates a very simple +menu layout for its applications.

These procedures, also referred to as "handlers", are +responsible for actually performing the computation associated with a +particular command. +Handlers should conform to the following type definition: +<pre> + typedef int (*CmdHandler)(const CmdLine &cmd); +</pre> +The <tt>CmdLine</tt> type manages the text of a particular command line, and +provides various methods for parsing that information (see details below). + +<p>The <tt>CmdEnv</tt> class manages the mapping of command names to +handlers. In particular, handler names are mapped to pointers to +objects derived from the base class <tt>CmdObject</tt>. All derived +classes of <tt>CmdObject</tt> are required to override the +<tt>operator()</tt> invocation virtual method. By using this virtual +function, handler objects are allowed to encapsulate arbitrary data in +their definition (i.e., to create closures). The standard scripting +framework defines two kinds of <tt>CmdObject</tt> handlers: (1) the +<tt>CmdFunction</tt> class to encapsulate normal functions and static +methods and (2) and the <tt>CmdMethod</tt> template class to +encapsulate member functions. + + +<p>New handler procedures (non-member functions) +can be associated with names using +the method: +<pre> + void register_command(const std::string& name, CmdHandler proc); +</pre> +Member functions can be bound to names uses the templated member +function: +<pre> + template<class T> + void register_method(const std::string& name, + T *obj, + int (T::*fn)(const CmdLine&)); +</pre> +Note that in both cases, prior bindings of <tt>name</tt> associated +with another handler will be overwritten. +Existing handlers can be located by name +using the method: +<pre> + CmdObject *lookup_command(const std::string& name); +</pre> +which returns <tt>NULL</tt> if no handler is bound to the given name. + +<h4>Submitting Text for Execution</h4> + +<p>Several procedures are available for submitting script text to the parsing +system. All of them require a <tt>CmdEnv</tt> argument that will determine +the mapping of command names to handlers. + +<p>The underlying method for parsing text is: +<pre> + int script_do_line(std::string &line, CmdEnv &env); + int script_do_line(const char *line, CmdEnv &env); +</pre> +It assumes that its input is a string consisting of a single line — any +embedded newlines will be treated like any other whitespace. +It will +split this line it a series of whitespace-separated tokens, interpreting the +first such token as a command name. If <tt>env</tt> provides a binding for +this name, the appropriate handler will be called. + +<p>For convenience, the scripting package also provides the following methods: +<pre> + int script_do_stream(std::istream &in, CmdEnv &env); + int script_do_file(const char *name, CmdEnv &env); + int script_do_string(const char *str, CmdEnv &env); +</pre> +They operate by extracting a single line from the input source and processing +that line with <tt>script_do_line()</tt>. They repeat this line-by-line +process until the file/stream/string has been exhausted. +The first time the processing of a line fails with an error code, these +procedures return this error code immediately without completing the +processing of the rest of the input. + + +<h3>Writing Command Handlers</h3> + +<p>A command procedure is declared as follows: +<pre> + int proc(const CmdLine& cmd); +</pre> +The <tt>CmdLine</tt> structure contains all the necessary data about the line +being processed. It provides the following fundamental accessors: +<pre> + class CmdLine + { + public: + const std::string &line; // Raw text of the (complete) line + std::string opname() const; // Name of the command being invoked + std::string argline() const; // Argument string + int argcount() const; // Number of argument tokens + }; +</pre> +The argument string returned by <tt>argline()</tt> is unparsed except that +whitespace following the command name and trailing whitespace at the end of +the line have been removed. + + +<p>It is up to the handler to parse the command line in whatever way it likes. +However, the scripting system assumes that command will be given +whitespace-separated token lists. Therefore, it pre-computes the indices of +these tokens in the command line text before invoking the handler. To access +an individual token, you can use the <tt>CmdLine</tt> methods: +<pre> + std::string token_to_string(int i) const; + double token_to_double(int i) const; + float token_to_float(int i) const; + int token_to_int(int i) const; +</pre> +Tokens are numbered from <tt>[0 .. argcount()-1]</tt>. Note that, for +efficiency, these methods <em>do not perform range checking.</em> It is up to +the caller to verify that the given indices are valid. + +<p>In addition to accessing single argument tokens, you can collect all +argument tokens into lists with the following <tt>CmdLine</tt> methods: +<pre> + int collect_as_strings(std::vector<std::string> &v) const; + int collect_as_numbers(std::vector<double> &v) const; + int collect_as_numbers(std::vector<int> &v) const; + + int collect_as_numbers(double *v, int size) const; + int collect_as_numbers(float *v, int size) const; + int collect_as_numbers(int *v, int size) const; +</pre> +These methods always return the number of tokens collected. +The <tt>vector</tt>-based methods will always collect all available tokens. +In contrast, those which accept raw arrays will either collect <tt>size</tt> +or <tt>argcount()</tt> tokens, whichever is smaller. + +<p>See the accompanying <a href="ex-script.html">scripting example</a> for more +details on how to write command handlers. + +</body> +</html> diff --git a/debian/fireflies/fireflies-2.08/libgfx/doc/start.html b/debian/fireflies/fireflies-2.08/libgfx/doc/start.html new file mode 100644 index 00000000..75da67d6 --- /dev/null +++ b/debian/fireflies/fireflies-2.08/libgfx/doc/start.html @@ -0,0 +1,136 @@ +<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" + "http://www.w3.org/TR/REC-html40/loose.dtd"> +<!-- $Id: start.html 111 2000-07-31 21:40:02Z garland $ --> + +<html> + +<head> +<title>libgfx: Getting Started</title> +<link rel=stylesheet href="cdoc.css" type="text/css"> +<meta name="Author" content="Michael Garland"> +</head> + +<body> + +<h2>Getting Started </h2> + +<p>The <tt>libgfx</tt> library can be used for writing both +console-oriented and GUI programs.

Therefore you must make sure that you only +access valid elements of arrays. + + +<h3>Arithmetic Operators</h3> + +<p>One of the primary goals of the vector package is to simplify the +coding of vector equations. To accomplish this, it makes use of +<em>operator overloading</em>. + + +<p><strong>Assignment</strong> +Vectors can be assigned the values of other vectors or scalars. +A vector assignment <tt>v = w</tt> copies the elements of <tt>w</tt> +into the corresponding elements of <tt>v</tt>. A scalar assignment +<tt>v = 1.0</tt> copies the given scalar, in this case <tt>1.0</tt>, +into each of the elements of <tt>v</tt>. + +<p><strong>Addition/Subtraction</strong> Vectors can be +added together either with the binary addition operator (<tt>u = v + +w</tt>) or the additive assignment operator (<tt>u += v</tt>). +Subtraction operates similarly, using subtraction rather than addition +operators. + +<p><strong>Scalar Multiplication/Division</strong> +Vectors can be multiplied by scalar values using either the binary +operator (<tt>v * 2.0</tt>) or the accumulation operator (<tt>v *= +2.0</tt>). Scalar division operates similarly. + +<p><strong>Inner Product</strong> +The inner product (or dot product) of two vectors is written with the +standard multiplication operator: <tt>v * w</tt>. + +<h3>Standard Vector Functions</h3> + +<p>All vector classes support a standard set of functions for +performing common operations on vectors. These functions are: +<pre> + <i>// Returns the squared length of the vector v</i> + inline double norm2(const Vec_& v); + + <i>// Returns the length of the vector v</i> + inline double norm(const Vec_& v); + + <i>// Adjusts v to have unit length. Mostly equivalent to v/=norm(v)</i> + inline void unitize(Vec_& v); +</pre> + +<p>Vector can also be read from and written to C++ iostreams using the +standard <tt><<</tt> and <tt>>></tt> operators. + +</body> + +</html> diff --git a/debian/fireflies/fireflies-2.08/libgfx/doc/vec2.html b/debian/fireflies/fireflies-2.08/libgfx/doc/vec2.html new file mode 100644 index 00000000..5faa016a --- /dev/null +++ b/debian/fireflies/fireflies-2.08/libgfx/doc/vec2.html @@ -0,0 +1,52 @@ +<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" + "http://www.w3.org/TR/REC-html40/loose.dtd"> +<!-- $Id: vec2.html 153 2000-09-05 16:11:26Z garland $ --> + +<html> + +<head> +<title>libgfx: Vector Math</title> +<link rel=stylesheet href="cdoc.css" type="text/css"> +<meta name="Author" content="Michael Garland"> +</head> + +<body> + +<h2>Vector Math</h2> + +<h3>class Vec2</h3> + +<p> This class implements a 2-dimensional real-valued vector. +Individual elements are represent with <code>double</code> precision +floating point numbers.
