collada.triangleset.TriangleSet¶

class collada.triangleset.TriangleSet(sources, material, index, xmlnode=None)¶

Class containing the data COLLADA puts in a <triangles> tag, a collection of triangles.

The TriangleSet object is read-only. To modify a TriangleSet, create a new instance using collada.geometry.Geometry.createTriangleSet().
If T is an instance of collada.triangleset.TriangleSet, then len(T) returns the number of triangles in the set. T[i] returns the i^th triangle in the set.

__init__(sources, material, index, xmlnode=None)¶: A TriangleSet should not be created manually. Instead, call the collada.geometry.Geometry.createTriangleSet() method after creating a geometry instance.

Methods

`__init__`(sources, material, index[, xmlnode])	A TriangleSet should not be created manually.
`bind`(matrix, materialnodebysymbol)	Create a bound triangle set from this triangle set, transform and material mapping
`generateNormals`()	If `normals` is None or you wish for normals to be recomputed, call this method to recompute them.
`generateTexTangentsAndBinormals`()	If there are no texture tangents, this method will compute them.
`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.

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 data.
