Decreasing poly count on models

Re: Decreasing poly count on models
Nicola Wrote:One thing that came in mind is how you compute the "point of view" mesh. In the simplest case, it could be a sphere enclosing the whole mesh, am i right? But i feel that it's more complex than that. If you have a convex model, there can be points that are never visible from the "outside sphere", but are still on the surface, and you could possibly see it "navigating inside" the model.

Although I can't prove it, I'm fairly certain that any external face must have an even (including zero) number of faces between it and the viewer. So your convex face can be found by counting intersections.

I'd like, one day, to make a program that can "auto BFC" a part by this method by tracing a ray and flipping surfaces as needed. But it's slow and thus not a routine you'd like to do every load. Do it once and prepackage a BFCd library.
