Hey guys, im new to opengl also to the forums, im making a 2D game and i wanted to know how to use a sprite sheet in opengl. i searched quite a bit but found nothing … i need to do this since it is a requirement for a project im working on.
Any useful links or code will be greatly appreciated 
thanks in advance
What is a sprite sheet?
I assume this is a texture containing a series of sprite images arranged in a regular gird…we call that a texture atlas.
Simply access each ‘sprite image’ by its texture coordinate when texturing the quad or sprite. For example, suppose you has only 4 ‘sprite’ images in this atlas texture. The first image would have its top-left texture coordinate as (0,0) and it’s top-right as (0.5,0).
One word about texture atlases. Make sure there are a couple of black pixels between each image so that linear filtering does not grab texels belonging to an adjacent image/sprite.
