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
