collada.polygons.Polygons

class collada.polygons.Polygons(sources, material, polygons, xmlnode=None)

Class containing the data COLLADA puts in a <polygons> tag, a collection of polygons that can have holes.

• The Polygons object is read-only. To modify a Polygons, create a new instance using collada.geometry.Geometry.createPolygons().

• Polygons with holes are not currently supported, so for right now, this class is essentially the same as a collada.polylist.Polylist. Use a polylist instead if your polygons don’t have holes.

__init__(sources, material, polygons, xmlnode=None)

A Polygons should not be created manually. Instead, call the collada.geometry.Geometry.createPolygons() method after creating a geometry instance.

Methods

__init__(sources, material, polygons[, xmlnode])	A Polygons should not be created manually.
bind(matrix, materialnodebysymbol)	Create a bound polygons from this polygons, transform and material mapping
getInputList()	Gets a collada.source.InputList representing the inputs from a primitive
load(collada, localscope, node)	Load and return a class instance from an XML node.
save()	Put all the data to the internal xml node (xmlnode) so it can be serialized.
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.
texbinormal_indexset	Read-only tuple of texture binormal index arrays.
texbinormalset	Read-only tuple of texture binormal arrays.
texcoord_indexset	Read-only tuple of texture coordinate index arrays.
texcoordset	Read-only tuple of texture coordinate arrays.
textangent_indexset	Read-only tuple of texture tangent index arrays.
textangentset	Read-only tuple of texture tangent 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.
xmlnode	ElementTree representation of the line set.
