<hr><a name="_details"></a><h2>Detailed Description</h2>
A mesh specially meant for use by the haze.
<p>
This mesh must be a convex hull. for example: cubes, boxes, spheres, cones, cylinders, pyramids. A convex hull object can be defined as follows: from any point inside the object, all of the polygons are completely visible (none are obscured by other polygons from the convex hull). The ordering of the vertices (vertice numbering) is important when multiple hulls are used. Also edges must be numbered, with a number for each undirected edge. (i.e. a->b and b->a have the same edge number). Polygons thus have N vertices and N edges. For a particular polygon, the edges return their points in clockwise ordering.
