VRML97-style Transform node

Classes

class Transform( GroupingTransform ):

Transform node based on VRML 97 Transform

The Transform node provides a fairly robust implementation of encapsulated local coordinate setup. You can set translation, rotation, scale, scaleOrientation and center and have the matrices properly setup and restored (even when you have exceeded the matrix stack depth).

boundingVolume( self , mode )

Calculate the bounding volume for this node

The bounding volume for a grouping node is the union of it's children's nodes, and is dependent on the children of the node's bounding nodes, as well as the children field of the node.

localMatrix( self , mode = None )

Calculate the transform's matrix manually

transform( self , mode = None , translate = 1 , scale = 1 , rotate = 1 )

Perform the actual alteration of the current matrix
