Im rendering some models with quite a lot of vertices and im searching for a way to make rendering faster. Any suggestions or usefull functions i can use?

If all the vertices are needed, than there is little optimization you can do, since most of it is already done  by minecraft. (Using callLists from openGL). An superior optimization technic(wich is easy to handle with the 'newer' pc's) is VBO. I can't explain the details about it, though it should be easy to find with a litle google research.

 

(And yea, this means that it will require a 'total' rewrite of the vanilla render codes. Im currently working on an api wich optimize rendering through the VBO technic, though it will take some time till Im able to make it public)

Hi

 

(1) first check that your models really are the cause of slow rendering

(2) make your models simpler.  Minecraft is supposed to look blocky after all

(3) If your models don't change shape often, compile them to a display list (Minecraft entities do this already - see ModelRenderer.render())
