My company need some tools for android mobile game.
1) Ray picking (gluUnProject function returns not exactly position)
2) Uploading to the scene any animated models which can be exported from 3d max. Bump uploading is optional functional.
3) ocean surface rendering.
4) 2d image buttons displaing on the screen. Button click event is required as well.

OpenGL ES skill is obligatory.
