Fastest Rendermode?
May 03, 2002 02:04 PM
Hi all!
I''ve a question!
Which is the fastest rendering mode??
Primitives? Vertex Lists? Display Arrays?
I hope you can help me!
Thanks a lot, Corrail

Indexed VAR/VAOs. See GL_NV_vertex_array_range[2] and GL_ATI_vertex_array_object.

depends on what you are rendering. particles and such dont do well in an indexed list. in fact, indexed lists are only faster if they significent reduce the amount of vertices that need to be processed (ie transformed, lit).
display lists are great for geometry that dont change, but depends in the card (do tests). vertex arrays are you general purpose speed up, but again care needs to be taken when doing dynamic updates to the array (ie particles).
the best way is to test each method for what your rendering and do some research on google.com
