VRML97 semantic node-types

Classes

class Auditory( object ):
Auditory nodes (nodes with produce sound)
class Background( Bindable ):
Background nodes
class Bindable( object ):
Bindable nodes
Note: All Bindables are also Children, though that isn't represented here.
class Children( object ):
Children nodes (Nodes which can belong to a Grouping)
class Fog( Bindable ):
Fog nodes
class Geometry( object ):
Geometry nodes (Nodes which can appear in the geometry field of shapes)
class Grouping( Traversable ):
Grouping nodes (Nodes which group children together)
class Interpolator( object ):
Interpolator nodes
class Light( object ):
Light nodes
class NavigationInfo( Bindable ):
NavigationInfo nodes
class PointingSensor( Sensor ):
Pointing-Device Sensor nodes
class Rendering( object ):
Rendering nodes (Shapes)
class Sensor( object ):
Sensor nodes
Note: All Sensors are also Children, though that isn't represented here.
class Texture( object ):
Texture nodes
class TimeDependent( object ):
TimeDependent nodes
class Transforming( Grouping ):
Nodes which alter the transform matrix for children
This is a fairly small set of types:
Transform Billboard
Billboard is not yet implemented, so there's only the one functional node in the type-set
localMatrices( self , translate = True , scale = True , rotate = True )
Calculate/lookup our local matrices
Certain operations want, e.g. just the rotation of an item, so we actually can store 2**3 possible variations of the local matrices. In practice we only see a very small number.
returns holder, where holder.data == (forward,inverse) matrix for the local node, each of which can be None
class Traversable( object ):
Traversable nodes (Nodes which have node attributes)
class Viewpoint( Bindable ):
Viewpoint nodes
