collada.source.IDRefSource

class collada.source.IDRefSource(id, data, components, xmlnode=None)

Bases: collada.source.Source

Contains a source array of ID references, as defined in the collada <IDREF_array> inside a <source>.

If r is an instance of collada.source.IDRefSource, then len(r) is the length of the shaped source. len(r)*len(r.components) would give you the number of values in the source. r[i] is the ith item in the source array.

__init__(id, data, components, xmlnode=None)

Create an id ref source instance.

Parameters:
  • id (str) – A unique string identifier for the source
  • data (numpy.array) – Numpy array (unshaped) with the source values
  • components (tuple) – Tuple of strings describing the semantic of the data, e.g. ('MORPH_TARGET') would cause data to be reshaped as (-1, 1)
  • xmlnode – When loaded, the xmlnode it comes from.

Methods

__init__(id, data, components[, xmlnode]) Create an id ref source instance.
load(localscope, node)
save() Saves the source back to xmlnode
id = None

The unique string identifier for the source

data = None

Numpy array with the source values. This will be shaped as (-1,N) where N = len(self.components)

components = None

Tuple of strings describing the semantic of the data, e.g. ('MORPH_TARGET')

xmlnode = None

ElementTree representation of the source.

save()

Saves the source back to xmlnode
