Modifying Other Classes That Use the Object3d Class
Other classes that use the Object3d class also will have to be modified. For example, the Cube class
that is derived from the Object3d class will have to be modified in terms of adding a Mesh input
parameter into the constructor and the call to the Object3d constructor. (See Listing 7-6.)
Listing 7-6. Modifying the Cube Class
public class Cube extends Object3d
Cube(Context iContext, Mesh iMesh , MeshEx iMeshEx, Texture[] iTextures, Material iMaterial,
Shader iShader)
{
super(iContext , iMesh , iMeshEx, iTextures, iMaterial, iShader);
}

apress.com to see other changes that have to be made to other classes.
