/********************************************************************************************** * * 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 * 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) * Multiple textures support, including compressed formats and mipmaps generation * Basic 3d 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) * * 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 * jar_xm (Joshua Reisenauer) for XM audio module loading * jar_mod (Joshua Reisenauer) for MOD audio module 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 (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) * * -- LICENSE -- * * 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) 2013-2016 Ramon Santamaria (@raysan5) * * This software is provided "as-is", without any express or implied warranty.
