WebAs for how it's so fast - GPUs are massively parallel computers, so they can do lots of triangles and lots of pixels at once, and with dedicated hardware to boot. It works the same as a software renderer. Just look up any source on GitHub. Now remember that designers don’t even know what to do with all the transistors a fab gives them today. Web21 de jun. de 2024 · As for one edge per triangle … oof. Not all the geometry is going to be convex. So, I would have to either submit the same triangle 2 times with different vertex labels or triangulate suboptimally (ie 4 triangles to render a rectangle for example–your radial decomposition) in order to always keep 1 exterior and 2 interior edges.

WebDividing a concave polygon (a) into a set of triangles (b) produces triangle edges (dashed) that are interior to the original polygon.
