Method Detail

generateTriangles

public abstract void generateTriangles(Action action,
                                       TriangleCallback cb)

Based on the state in the given Action, calls the specified triangle callback for each triangle in the shape. Coordinates are specified in the local coordinate system of this shape; the caller must transform them into the world coordinate system if necessary.

rayPick

public void rayPick(RayPickAction action)

Description copied from class: Node

Support for the built-in RayPickAction. Note that supplying virtual methods in Node subclasses to support various actions is not required due to the framework supporting action methods, but for built-in actions it may make it simpler.
