de.grogra.imp3d.objects.SceneTree.InnerNode

Enclosing class:

SceneTree

public static class SceneTree.InnerNode
extends SceneTree.Node

This class represents an inner node of a scene tree. Inner nodes have a set of children, stored as a linked list of SceneTree.Nodes, and specify a coordinate transformation by the fields m00 to m23. The coordinate transformation transforms from the children's coordinate systems to the coordinate system of this inner node.
