View Full Version : Polycount - Vertex Draw Count

Was seeing a number of people asking about what is the poly count for characters... etc in a game. Hadn't been working on any of the lastest platforms(PS3, Xbox360), so decided to contact a few old pals still grinding away at it.

Their take is now most people do not talk about polycounts but vertex draw counts instead. Which far as I can reason is object vertex count + UV vertex count * number of shader draws for an object.

Example Cube single color standard lighting 4verts cube + 4verts UV single render pass = 8 draw verts

Cube seperate Texture with UV mapping per face, with diffuse/normal/specular 4verts cube + 24verts UV (6face*4UVper) * 3 shader draw passes = 84 draw verts

Any one else working out there hear much on this type of size count, or I guess render count size.

We talk of some similar counts. We try to limit out material IDs in Unreal for the very same shader draw count that your talking about, because it is like rendering that object X number of times.
