Why is nothing simple???
I define MySphere as an extension of Sphere.
I add it to my scene graph.
MySphere theSphere = new MySphere();
theSphere.setAppearance(createAppearanceProton());
theSphere.setCapability(Shape3D.ALLOW_APPEARANCE_READ);
theSphere.setCapability(Shape3D.ALLOW_APPEARANCE_WRITE);
objPSize.addChild(theSphere);
Note the ALLOW_APPEARANCE_READ capability....
After the scene is compiled and active, I want to change the sphere's
color. So I get the appearance of the sphere by
Appearance PA = theApp.theSphere.getAppearance();
Material theMaterial = PA.getMaterial();
theMaterial.setDiffuseColor(red, green, blue);
But this fails with a
"Shape3D: no capability to get appearance"
exception.
So how do you set the capability to read (and write) the
appearance of a Sphere object? Or is there some other
problem which is preventing me from doing this?
