Appearance Objects - Interactive Web-Based Virtual Reality with Java 3D - page 76

The following steps are involved in the creation of an appearance object:

1. Create an appearance object.

2. Create the necessary attributes, materials object, and texture related objects.

3. Reference the objects in step 2 from the appearance object.

4. Reference the appearance object from the Shape3D object.

Figure 1 shows the how an appearance object is related to other relevant objects. As
shown in Figure 1, an appearance object can refer to several different appearance attribute
objects, which belong to basically the NodeComponent classes (Walsh & Gehringer, 2002).
The important classes are

• PointAttributes

• LineAttributes

• PolygonAttributes

• ColoringAttributes

• TransparencyAttributes

• RenderingAttributes

• Material

• TextureAttributes

• Texture

• TexCoordGeneration
