I don't recall seeing any mention of optimised quad processing, and they used to be split into 2 triangles since the hardware only rasterised triangles.

You may be right, but I was talking specifically about _indexed_ triangle strips (which both reduce bandwidth and utilise the cache). However, stripifying typically increases the number of draw calls, so... > This is true if you're programming in C/C++, but the performance > overhead of a foreign function call (from Python to OpenGL) usually > far outweighs the cost of a state change, so they're equally > inefficient. I forgot about ctypes overhead - that should outweigh pretty much every thing else. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "pyglet-users" group.
