WebHere is an example of an ordered draw: If we are rendering triangles the GPU will generate the following set: V0/1/2, V3/4/5, V6/7/8, etc. Here is an example of an indexed draw: In this case the GPU will generate the following triangles: V2/0/1, V5/2/4, V6/5/7, etc. Using index draws in OpenGL requires generating and populating an index buffer. http://www.opengl-tutorial.org/beginners-tutorials/tutorial-2-the-first-triangle/
