/**********************************************************************************************
*
* raylib 1.5 .0 ( www . raylib . com )
*
* A simple and easy - to - use library to learn videogames programming
*
* Features :
* Library written in plain C code ( C99 )
* Uses C # PascalCase / camelCase notation
2016-07-18 18:08:13 +03:00
* Hardware accelerated with OpenGL ( 1.1 , 2.1 , 3.3 or ES 2.0 )
* Unique OpenGL abstraction layer ( usable as standalone module ) : [ rlgl ]
* Powerful fonts module with SpriteFonts support ( XNA bitmap fonts , AngelCode fonts , TTF )
2016-06-11 12:21:55 +03:00
* Multiple textures support , including compressed formats and mipmaps generation
2016-07-18 18:08:13 +03:00
* Basic 3 d support for Shapes , Models , Billboards , Heightmaps and Cubicmaps
* Materials ( diffuse , normal , specular ) and Lighting ( point , directional , spot ) support
* Powerful math module for Vector , Matrix and Quaternion operations [ raymath ]
* Audio loading and playing with streaming support and mixing channels ( WAV , OGG , XM , MOD )
* VR stereo rendering support with configurable HMD device parameters
* Multiple platforms support : Windows , Linux , Mac , Android , Raspberry Pi , HTML5 and Oculus Rift CV1
* Custom color palette for fancy visuals on raywhite background
* Minimal external dependencies ( GLFW3 , OpenGL , OpenAL )
2016-06-11 12:21:55 +03:00
*
* Used external libs :
* GLFW3 ( www . glfw . org ) for window / context management and input
* GLAD for OpenGL extensions loading ( 3.3 Core profile , only PLATFORM_DESKTOP )
* stb_image ( Sean Barret ) for images loading ( JPEG , PNG , BMP , TGA , PSD , GIF , HDR , PIC )
* stb_image_write ( Sean Barret ) for image writting ( PNG )
* stb_vorbis ( Sean Barret ) for ogg audio loading
* stb_truetype ( Sean Barret ) for ttf fonts loading
2016-07-18 18:08:13 +03:00
* jar_xm ( Joshua Reisenauer ) for XM audio module loading
* jar_mod ( Joshua Reisenauer ) for MOD audio module loading
2016-06-11 12:21:55 +03:00
* OpenAL Soft for audio device / context management
* tinfl for data decompression ( DEFLATE algorithm )
*
* Some design decisions :
* 32 bit Colors - All defined color are always RGBA ( struct Color is 4 byte )
* One custom default font is loaded automatically when InitWindow ( )
* If using OpenGL 3.3 or ES2 , several vertex buffers ( VAO / VBO ) are created to manage lines - triangles - quads
* If using OpenGL 3.3 or ES2 , two default shaders are loaded automatically ( internally defined )
