GDK=Cross-Platform C++ Mobile Game Development Kit

The GDK is a Software Development Kit for building cross-platform C++ mobile (and desktop) games.

Half of the GDK is a full C++ application shell for building a game that runs on PC, MAC, & iOS (Android coming soon). With direct support for OpenGL 2.1 & OpenGL ES 2.0 for rendering. And robust libraries for Math, Assets, Rendering, etc

The other Half is a full suite of content tools for compiling various game assets (Textures, sprites, animations, models, shaders, fonts, etc) into each platform's native format. (Which the C++ side seamlessly loads & uses)
