I haven't been following the list closely for the last couple of weeks, so I
don't know if this problem has already been discussed....
I have a CAD like Java 3D program.
You can select a predefined polyhedron to be displayed in a scene (cube, or
tetrahedron, etc).
For any polyhedron, you can display ("turn on/off") the polyhedron's
1) Vertex spheres
2) edges as lines
3) edges as cylinders
4) faces as planes.
I accomplish this by defining a Switch node and attaching a BranchGroup for
each of the 4 cases listed above. (These BranchGroups contains the geometry
Shape definitions.)
You can also combine two or more polyhedra together to define what I call a
"combined object".
To accomplish this, I define a new scene object (BranchGroup)"BG2" and
attach it to the live scene graph "BG1". Then I detach the Switch node for
a polyhedron from "BG1" and attach it to "BG2".
The Problem: When I do this, the polyhedron displays all 4 features list
above, *even when the Switch bits have not been set* to display all 4
features.
For example, if only (3) above it set to be displayed, so the polyhedron
only displays as cylinder edges, then I detach it from BG1 and add it to
BG2, the polyhedron will be displayed with vertex spheres, and face planes
showing in addition to the cylinder edges.
I print out the Switch bit right after the I add it to BG2,
System.out.println("BS: "+theLastSO.SNPropertiesBS);
and it shows only one bit set (3), yet all 4 features are actually being
displayed.
I even reset the Switch bit after detach and re-attach
theLastSO.SNProperties.setChildMask(theLastSO.SNPropertiesBS);
yet the polyhedron still is displayed with all 4 features showing.
I don't recall having this problem before I started using Beta 2.
Anyone else seeing a problem when a Switch is detached from a BranchGroup
and then added to another BranchGroup?
(Actually, I have a BranchGroup just above the Switch and it is this BG I am
detaching and re-attaching, but I thought another BG would make the
description too confusing to follow.)

Bob Gray
