I dont know if this is the right forum, but I just started using OpenGL 2.0 in Android. I've mainly worked with old OpenGL versions before (and DirectX). So anyway, can you guys recommend any good library for matrices and such, since all transformations are removed in ES 2.0? Hopefully I won't have to spend two days on writing this myself just to be able to play around. I'm using the Android NDK and C++.
