OpenGLContext.scenegraph.nodepath

node-path implementation for OpenGLContext

Classes

class _NodePath( object ):

OpenGLContext-specific node-path class

At the moment this only adds a single method, transform() which traverses the path, calling transform() for each Transforming node which has a transform method.

quaternion( self )

Get summary quaternion for all rotations in stack

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

For each Transforming node, do OpenGL transform

Does _not_ push-pop matrices, so do that before if you want to save your current matrix. This method is useful primarily for storing paths to, for instance, bindable nodes, where you want to be able to rapidly transform down to the node, without needing a full traversal of the scenegraph.
