Class EvOpLevelsetsFastMarching3D

java.lang.Object
  endrov.flow.EvOpGeneral
      endrov.flow.EvOpStack
          endrov.flowLevelsets.EvOpLevelsetsFastMarching3D

public class EvOpLevelsetsFastMarching3D
extends EvOpStack

3D levelsets distance calculation by fast marching. As EvOp, give speed, then starting points as mask (!=0 is a starting point). returns distance and origin color.
