tree structure composed of some asymmetric images with directionality (figure 1 ). From the perspective of the program, the realistic 3D scenario we see in a Java3D application is actually a series of objects defined by Java3D. These objects are not disordered, and they are not unrelated. To enable normal display of 3D images, you must follow the Java3D scene map rules. Observe Figure 1. The structure of the Java3D scene chart consists of various objects:
