/********************************************************************************************** * * raylib 1.2 (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 * Hardware accelerated with OpenGL (1.1, 3.3+ or ES2) * Unique OpenGL abstraction layer [rlgl] * Powerful fonts module with SpriteFonts support * Multiple textures support, including DDS and mipmaps generation * Basic 3d support for Shapes, Models, Heightmaps and Billboards * Powerful math module for Vector and Matrix operations [raymath] * Audio loading and playing with streaming support (WAV and OGG) * Multiplatform support, including Android devices and Raspberry Pi * * Used external libs: * GLFW3 (www.glfw.org) for window/context management and input * GLEW for OpenGL extensions loading (3.3+ and ES2) * 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 * OpenAL Soft for audio device/context management * tinfl for data decompression (DEFLATE algorithm) * * Some design decisions: * 32bit Colors - All defined color are always RGBA * 32bit Textures - All loaded images are converted automatically to RGBA textures * SpriteFonts - All loaded sprite-font images are converted to RGBA and POT textures * One custom default font is loaded automatically when InitWindow() * If using OpenGL 3.3+ or ES2, one default shader is loaded automatically (internally defined) * * -- LICENSE (raylib v1.2, September 2014) -- * * raylib is licensed under an unmodified zlib/libpng license, which is an OSI-certified, * BSD-like license that allows static linking with closed source software: * * Copyright (c) 2013 Ramon Santamaria (Ray San - raysan@raysanweb.com) * * This software is provided "as-is", without any express or implied warranty.
