|
* raylib 1.0.3 (www.raylib.com)
|
|
*
|
|
* A simple and easy-to-use library to learn C videogames programming
|
|
*
|
|
* Features:
|
|
* Library written in plain C code (C99)
|
|
* Uses C# PascalCase/camelCase notation
|
|
* Hardware accelerated with OpenGL 1.1
|
|
* Powerful fonts module with SpriteFonts support
|
|
* Basic 3d support for Shapes and Models
|
|
* Audio loading and playing
|
|
*
|
|
* Used external libs:
|
|
* GLFW3 (www.glfw.org) for window/context management and input
|
|
* stb_image (Sean Barret) for images loading (JPEG, PNG, BMP, TGA, PSD, GIF, HDR, PIC)
|
|
* OpenAL Soft for audio device/context management
|
|
*
|
|
* 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()
