Web14 de jan. de 2014 · If everything else is equal, drawing a 50k mesh in 1 draw call is going to be much faster than drawing it in 10k draw calls. But if your mesh is composed of multiple strips, or (even worse) a combination of strips and fans, you can't do it in a single draw call without (1) using indices, or (2) introducing degenerate triangles. 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.
