__init__(collada, id, name, sourcebyid, primitives=None, xmlnode=None, double_sided=False)
Create a geometry instance
| Parameters: |
- collada (collada.Collada) – The collada object this geometry belongs to
- id (str) – A unique string identifier for the geometry
- name (str) – A text string naming the geometry
- sourcebyid – A list of collada.source.Source objects or
a dictionary mapping source ids to the actual objects
- primitives (list) – List of primitive objects contained within the geometry.
Do not set this argument manually. Instead, create a
collada.geometry.Geometry first and then append
to primitives with the create* functions.
- xmlnode – When loaded, the xmlnode it comes from.
- double_sided (bool) – Whether or not the geometry should be rendered double sided

-
bind(matrix, materialnodebysymbol)
Binds this geometry to a transform matrix and material mapping.
The geometry’s points get transformed by the given matrix and its
inputs get mapped to the given materials.
