collada.scene.MaterialNode¶
-
class
collada.scene.
MaterialNode
(symbol, target, inputs, xmlnode=None)¶ Bases:
collada.scene.SceneNode
Represents a material being instantiated in a scene, as defined in the collada <instance_material> tag.
-
__init__
(symbol, target, inputs, xmlnode=None)¶ Creates a material node
Parameters: - symbol (str) – The symbol within a geometry this material should be bound to
- target (collada.material.Material) – The material object being bound to
- inputs (list) – A list of tuples of the form
(semantic, input_semantic, set)
mapping texcoords or other inputs to material input channels, e.g.('TEX0', 'TEXCOORD', '0')
would map the effect parameter'TEX0'
to the'TEXCOORD'
semantic of the geometry, using texture coordinate set0
. - xmlnode – When loaded, the xmlnode it comes from
Methods
__init__
(symbol, target, inputs[, xmlnode])Creates a material node load
(node)objects
()Iterate through all objects under this node that match tipo. save
()Saves the material node back to xmlnode
-
symbol
= None¶ The symbol within a geometry this material should be bound to
-
target
= None¶ An object of type
collada.material.Material
representing the material object being bound to
-
inputs
= None¶ A list of tuples of the form
(semantic, input_semantic, set)
mapping texcoords or other inputs to material input channels, e.g.('TEX0', 'TEXCOORD', '0')
would map the effect parameter'TEX0'
to the'TEXCOORD'
semantic of the geometry, using texture coordinate set0
.
-
xmlnode
= None¶ ElementTree representation of the material node.
-
objects
()¶ 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
