GLSL effect

Dear all,

I saw in jmetest, there're 2 file testcubemapglsl.frag and testcubemapglsl.vert . As far as I know that these files are GLSL shader for model. But, I don't know how to create these files because they're so complicated? Any one can help me?

You have to study GLSL. Maybe a book can help you out!
