10.8 `PolyhedronGeom` -- Polyhedron geometry

The PolyhedronGeom class stores a collection of general planar concave polygons that may also contain holes. Each polygon is described by a sequence of vertex loops. The first loop defines the polygon boundary and each subsequent loop describes a hole. Each loop is a sequence of vertex indices.

class PolyhedronGeom( ): Creates an empty polyhedron.

A PolyhedronGeom has the following slots:

Slot	Type	Access	Description
`verts_slot`	vec3 array	rw	The polygon vertices

verts: This attribute contains the sequence of polygon vertices.

hasPolysWithHoles( ): Return True if there is at least one polygon with a hole.

getNumPolys( ): Return the number of polygons.

getNumLoops( poly): Return the number of vertex loops in the polygon with index poly.

getNumVerts( poly, loop): Return the number of vertex indices in one particular loop. poly is the polygon index and loop the loop index.

setNumPolys( num): Allocate space for num polygons.

setNumLoops( poly, num): Allocate space for num loops in the polygon with index poly.

getLoop( poly, loop): Return a loop from a polygon. poly is the polygon index and loop the loop index. The return value is a sequence of vertex indices.

setLoop( poly, loop, vloop): Set a new polygon loop. poly is the polygon index, loop the loop index and vloop a sequence of vertex indices.

getPoly( poly): Return a polygon. poly is the polygon index. The return value is a sequence of vertex loops.

setPoly( poly, polydef): Set a polygon. poly is the polygon index and polydef a sequence of vertex loops.
