Examples of javax.media.j3d.Shape3D

javax.media.j3d.Shape3D
The Shape3D leaf node specifies all geometric objects. It contains a list of one or more Geometry component objects and a single Appearance component object. The geometry objects define the shape node's geometric data. The appearance object specifies that object's appearance attributes, including color, material, texture, and so on.
The list of geometry objects must all be of the same equivalence class, that is, the same basic type of primitive. For subclasses of GeometryArray, all point objects are equivalent, all line objects are equivalent, and all polygon objects are equivalent. For other subclasses of Geometry, only objects of the same subclass are equivalent. The equivalence classes are as follows:
- GeometryArray (point): [Indexed]PointArray
- GeometryArray (line): [Indexed]{LineArray, LineStripArray}
- GeometryArray (polygon): [Indexed]{TriangleArray, TriangleStripArray, TriangleFanArray, QuadArray}
- CompressedGeometry
- Raster
- Text3D
When Shape3D is used with multiple geometry components, Java 3D may choose to use individual geometry bounds instead of the shape's bounds for region of influence operations, such as lighting. For example, the individual characters of a Text3D shape object may be rendered with a different light set.
