This is confusing at most. Since you are doing 2D triangles use copy_v2_fl2 for that.


Optional: The real gain here would be to check previous point and see if it is adjacent. In this case you would just modify previous quad.


This is doing double allocation and a useless memcpy in GPU_vertbuf_attr_fill. Prefer allocating the GPUVertBuf here and populate them directly.

This revision now requires changes to proceed.Thu, Feb 13, 3:29 PM

Also rename vert_data to vert_pos.

address review points.


I could do this, but I don't really want to increase complexity here. There is significant performance increase already.
Another thing is, that I am iterating (constantly modified) ghash, so it is likely that we will get a lot of frames out of order.

This revision is now accepted and ready to land.Thu, Feb 13, 5:52 PM
