Raspberry Pi OpenGL ES 2.0 Graphics Engine

A portable, high speed graphics engine in OpenGL ES 2.0 for the Raspberry Pi B/B+ and Zero in C++

Contains the following example projects;

• SceneViewer Load modified OBJ files to view fully collidable scenes with animated textures
• ScreenRunner Animated backgrounds with Gamepad input for changing between screens

Compiling on Raspberry Pi

• Run 'make' for particular project in Projects folder

Note: SDL2.0.5 is installed in Raspbian Stretch although you will need to use SDL2.0.9 for the shaders in these projects to work.

Please follow the instructions on ChoccyHobNob's website to install SDL2.0.9 (or the latest SDL2) on your Raspberry Pi;
