How to use ModelClip nodes E-mail
User Rating: / 2
PoorBest 

ModelClip nodes can clip visual objects in arbitrary ways. A ModelClip object defines a set of six clipping planes of arbitrary orientations in the local coordinate system. The clipping planes define halfspaces for which vertices are culled from rendering.

public class ModelClipExample extends JFrame {
  public ModelClipExample() {
    ...
  }

  public BranchGroup createSceneGraph() {
    BranchGroup objRoot = new BranchGroup();

    TransformGroup objSpin=new TransformGroup();
    objSpin.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);
    objRoot.addChild(objSpin);
    
    objSpin.addChild(new ColorCube(0.4));
    
    Alpha rotationAlpha=new Alpha(-1,4000);
    RotationInterpolator rotator=new RotationInterpolator(rotationAlpha,objSpin);
    
    //a bounding sphere specifies a region a behavior is active
    BoundingSphere bounds=new BoundingSphere();
    rotator.setSchedulingBounds(bounds);
    objSpin.addChild(rotator);
    
    //create a ModelClip object and set the clip planes
    ModelClip modelClip = new ModelClip();
    modelClip.setInfluencingBounds(bounds);  
    boolean enables[] {true, true, false, false, false, false}

    modelClip.setPlane(0new Vector4d(100, -0.1));
    modelClip.setPlane(1new Vector4d(0,1,0,-0.1));
    objRoot.addChild(modelClip);  

    return objRoot;
