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.
