Just an advice. Do not try to start by learning gles in a emulator. It's tricky and it's not real. There are more differences and incompabilities that people can think about. Some of them can be very puzzling and difficult to find inside Osg.

So i think i need to go through shader first! :-) Also, i used OpenGL emulation for OSG build. now i think i will try by installing OpenGL ES library and perform build for actual GLES2. > > I will update you soon regarding my activities. > > Thanks again for help! > > Regards/Ankur > > > > Christian wrote: >> Hi, >> >> just one addition to my previous post: Normally you wouldn't define an extra vertex attribute array for the vertex color/normal as I did in this test code.
