Hi,

I'm looking for a piece of terminology and I'm not sure if "hull convexity" or "set convexity" describes the idea...

I'm looking to implement a test in my program that checks if a particular geometric figure is (convex?), meaning that none of its edges penetrate any of the figure's surfaces.

I know this is related to Poincare's conjecture... the idea that an object could be filled with water because its internal space is continuous.

First, what would you call such a test in the world of computer graphics?

Second, can anyone point me to some documentation or tutorials, etc. which might help me to implement such a function?

Thanks!
