Hi.
I want to compute several triangle models' projective area on the view plane. My current method is that I write a soft-ware rasterizer and do the rectangle culling of triangle pixels out of the view rectangle and then computer the area.
As there is no hard-ware culling, it's time consuming. I wonder is there any idea of another way of triangle culling.
For example, can the triangles be parameterized into a vector, and do a 2D vector culling? Is there any paper about it?
Or as the area could be coarse, is there any better parameter way?
Sincere.
