collada.source.NameSource

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

Bases: collada.source.Source

Contains a source array of strings, as defined in the collada <Name_array> inside a <source>.

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

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

Create a name 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. ('JOINT') would cause data to be reshaped as (-1, 1)
  • xmlnode – When loaded, the xmlnode it comes from.

Methods

__init__(id, data, components[, xmlnode]) Create a name source instance.
load(collada, localscope, node) Load and return a class instance from an XML 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. ('JOINT')

xmlnode = None

ElementTree representation of the source.

save()

Saves the source back to xmlnode

static load(collada, localscope, 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
