Is there a definition for "convexity" of spatial (nonon-planar) polygons?

I was thinkthinking that there should exist a definition for "convexity" oof spatial polygons. A planar convex quadrilateral that has one vertex moved (perpendicularly) out of the plane should continue to be convex in such a definition. Does someone knowsknow something in this direction?
