Hi Florin and Micheal,
thanks for your feedback. I am having problems managing the appearnance dynamically.
I have two shape3d's. I wish to turn one shape3d invisible. I plan to do this by
setting the rendering attributes to invisible. When i set the capabilities and apply
new appearance to one shape3d it turns both the shape3d's off. I dont know why. Can
you send me a sample code which has two shape3d's and changes the appearance of a
single shape3d dynamically(user clicks button).
Sorry to bug you too much but i'm having some deadlines.
thanks

All the capabilities must be set *before* the object is compiled or made live.
After that, if you have set the correct capabilities, you can change what ever
you want.
Cheers,
Florin

I tried that too. getting the appearance, then getting the renderingattributes
and changing them, but it doesnt allow me to apply the changed-renderingattributes to
the appearance(which is of a live object). Here is the code. Please let me know where
i am doing wrong
Appearance a3;
a3 = shape1.getAppearance();
a3.setCapability(Appearance.ALLOW_RENDERING_ATTRIBUTES_WRITE);
a3.setCapability(Appearance.ALLOW_RENDERING_ATTRIBUTES_READ);
a3.setCapability(shape1.ALLOW_APPEARANCE_READ);
a3.setCapability(shape1.ALLOW_APPEARANCE_WRITE);
r= a3.getRenderingAttributes();
r.setVisible(false);
thanks
Venu

The capability bits don't modify the Appearance itself! They only say
what
can be modified after the object was compiled. To change the
properties of
your Appearance object, try the different get...() methods to access
the
Texture, Color, MaterialAttributes etc. (please refer
http://java.sun.com/products/java-
media/3D/forDevelopers/J3D_1_3_API/j3dapi/javax/media/j3d/Appearance.html
for all methods which can be used for getting and setting the different
values).
