collada.scene.MatrixTransform

class collada.scene.MatrixTransform(matrix, xmlnode=None)

Bases: collada.scene.Transform

Contains a matrix transformation as defined in the collada <matrix> tag.

__init__(matrix, xmlnode=None)

Creates a matrix transformation

Parameters:
  • matrix (numpy.array) – This should be an unshaped numpy array of floats of length 16
  • xmlnode – When loaded, the xmlnode it comes from

Methods

__init__(matrix[, xmlnode]) Creates a matrix transformation
load(collada, 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.
matrix = None

The resulting transformation matrix. This will be a numpy.array of size 4x4.

xmlnode = None

ElementTree representation of the transform.

static load(collada, node)

Load and return a class instance from an XML node.

Inspect the data inside node, which must match this class tag and create an instance out of it.

Parameters:
  • collada (collada.Collada) – The collada file object where this object lives
  • localscope (dict) – If there is a local scope where we should look for local ids (sid) this is the dictionary. Otherwise empty dict ({})
  • node – An Element from python’s ElementTree API
save()

Put all the data to the internal xml node (xmlnode) so it can be serialized.
