collada.polylist.BoundPolylist

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

Bases: collada.primitive.BoundPrimitive

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 i^th 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.

Attributes

normal	Read-only numpy.array of size Nx3 where N is the number of normal values in the primitive’s normal source array.
normal_index	Read-only numpy.array of size Nx3 where N is the number of vertices in the primitive.
texcoord_indexset	Read-only tuple of texture coordinate index arrays.
texcoordset	Read-only tuple of texture coordinate arrays.
vertex	Read-only numpy.array of size Nx3 where N is the number of vertex points in the primitive’s vertex source array.
vertex_index	Read-only numpy.array of size Nx3 where N is the number of vertices in the primitive.

normal

Read-only numpy.array of size Nx3 where N is the number of normal values in the primitive’s normal source array. The values will be transformed according to the bound transformation matrix.

normal_index

Read-only numpy.array of size Nx3 where N is the number of vertices in the primitive. To get the actual normal values, one can use this array to select into the normals array, e.g. normal[normal_index]. The values will be transformed according to the bound transformation matrix.

texcoord_indexset

Read-only tuple of texture coordinate index arrays. Each value is a numpy.array of size Nx2 where N is the number of vertices in the primitive. To get the actual texture coordinates, one can use the array to select into the texcoordset array, e.g. texcoordset[0][texcoord_indexset[0]] would select the first set of texture coordinates. The values will be transformed according to the bound transformation matrix.

texcoordset

Read-only tuple of texture coordinate arrays. Each value is a numpy.array of size Nx2 where N is the number of texture coordinates in the primitive’s source array. The values will be transformed according to the bound transformation matrix.

vertex

Read-only numpy.array of size Nx3 where N is the number of vertex points in the primitive’s vertex source array. The values will be transformed according to the bound transformation matrix.

vertex_index

Read-only numpy.array of size Nx3 where N is the number of vertices in the primitive. To get the actual vertex points, one can use this array to select into the vertex array, e.g. vertex[vertex_index]. The values will be transformed according to the bound transformation matrix.

triangleset()

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

Return type:collada.triangleset.BoundTriangleSet

polygons()

Iterate through all the polygons contained in the set.

Return type:generator of collada.polylist.Polygon

shapes()

Iterate through all the polygons contained in the set.

Return type:generator of collada.polylist.Polygon
