Beaglebone Black OpenGL ES Demo

Does anyone know of an example of an OpenGL ES program on BBB please? I understand that the Debian 3.14 kernel provides OpenGL drivers, but that’s about it - I can’t seem to find any good source of information.

I want to create a how-to for BBB on this site ( to help others who may find themselves in a similar situation.

Any hints/tips/pointers to sources of information etc gratefully received.
