Title: GeometryUpdater

Do you need to detach/reattach to update the geometry?  Can you not update/change the TriangleArray coordinates and normals without detaching the Shape3D from the scene graph?  I don't think you need to detach.....

So by not using the GeometryUpdater and following the detach/reattach

approach, am I forced to recreate all GeometryArrays on a Shape node.

Or, if I have a reference to the Shape, can I just detach, modify the individual

geometry arrays that I care about( add/remove/modify )  and then reattach.

And this will all have to be done in a thread-safe manner by me.

 

Also, if I understand, this approach basically just means that I will take

a performance hit when I reattach because j3d will copy all data

again to the graphics device.  Is this correct? 

 

BTW, Thanks for all the replies.
