Examples of javax.media.j3d.Geometry

javax.media.j3d.Geometry
Geometry is an abstract class that specifies the geometry component information required by a Shape3D node. Geometry objects describe both the geometry and topology of the Shape3D nodes that reference them. Geometry objects consist of four generic geometric types:
- Compressed Geometry
- GeometryArray
- Raster
- Text3D
Each of these geometric types defines a visible object or set of objects. A Geometry object is used as a component object of a Shape3D leaf node.

    backgroundAppearance.setCapability(Appearance.ALLOW_COLORING_ATTRIBUTES_READ);
    backgroundColoringAttributes.setCapability(ColoringAttributes.ALLOW_COLOR_WRITE);
    
    Geometry halfSphereGeometry = createHalfSphereGeometry();   
    final Shape3D halfSphere = new Shape3D(halfSphereGeometry, backgroundAppearance);
    BranchGroup backgroundBranch = new BranchGroup();
    backgroundBranch.addChild(halfSphere);
    
    final Background background = new Background(backgroundBranch);
