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 primitiveload
(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.
