Recently, Fall to GLSL which is OpenGL Shader langauge study.

GLSL is cross-platform compatibility on multiple operating systems, and now I put it on android.
GLSL has the ability to write shaders that can be used on any hardware vendor's graphics card that supports it.

Thanks to Kirby and paulofalcao.
