collada.scene.ExtraNode

class collada.scene.ExtraNode(xmlnode)

Bases: collada.scene.SceneNode

Represents extra information in a scene, as defined in a collada <extra> tag.

__init__(xmlnode)

Create an extra node which stores arbitrary xml

Parameters:xmlnode – Should be an ElementTree instance of tag type <extra>

Methods

__init__(xmlnode) Create an extra node which stores arbitrary xml
load(collada, node) Load and return a class instance from an XML node.
objects(tipo[, matrix]) Iterate through all objects under this node that match tipo.
save() Put all the data to the internal xml node (xmlnode) so it can be serialized.
xmlnode = None

ElementTree representation of the extra node.

objects(tipo, matrix=None)

Iterate through all objects under this node that match tipo. The objects will be bound and transformed via the scene transformations.

Parameters:
  • tipo (str) – A string for the desired object type. This can be one of ‘geometry’, ‘camera’, ‘light’, or ‘controller’.
  • matrix (numpy.matrix) – An optional transformation matrix
Return type:

generator that yields the type specified
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.
