collada.polylist.BoundPolylist

class collada.polylist.BoundPolylist(pl, matrix, materialnodebysymbol)

A polylist bound to a transform matrix and materials mapping.

  • If P is an instance of collada.polylist.BoundPolylist, then len(P) returns the number of polygons in the set. P[i] returns the ith polygon in the set.

__init__(pl, matrix, materialnodebysymbol)

Create a bound polylist from a polylist, transform and material mapping. This gets created when a polylist is instantiated in a scene. Do not create this manually.

Methods

__init__(pl, matrix, materialnodebysymbol)

Create a bound polylist from a polylist, transform and material mapping.

polygons()

Iterate through all the polygons contained in the set.

shapes()

Iterate through all the polygons contained in the set.

triangleset()

This performs a simple triangulation of the polylist using the fanning method.
