Class BezierPatch

java.lang.Object
  com.jme.scene.BezierPatch

All Implemented Interfaces:

Savable

public class BezierPatch
extends java.lang.Object
implements Savable

BezierPatch defines a 4x4 mesh of control points. The patch will be enough to generate a single section of a BezierMesh. The detail level of the patch determines the smoothness of the resultant BezierMesh.
