Which is the best , are any easiest way for doing this please suggests me.

i am completely to newie to thisForum & OpenGL also.
Please suggests me for solving this

Thanks Inadvance.

I’d recommend you first decide if you want to make games or do graphics programming for games, they are related but different tasks. If you want to make games use an existing game engine (there are free ones, e.g. unity). If you want to learn graphics programming using OpenGL start with one of the tutorials linked from the wiki.

Thank You For Your Response
