Subject: Rotating One Vector Into Another
Hi
I have two vector3ds. I want to rotate one so that it falls along the same
line as the other. Does anyone have any suggestions on how to do this? I

I'm rapidly going insane here. The latest is that I'm getting a
javax.media.j3d.CapabilityNotSetException: Appearance: no capability to get

at javax.media.j3d.Appearance.getRenderingAttributes(Appearance.java:415)
on an object for which I have explicitly set

Following up on my own post here:
I just tried setting the ALLOW_DETACH capability for the branchgroup
nodes to be removed, and I got a different error when removeChild() is
invoked:

removed
This is truly infuri
I get a "CapabilityNotSetException: Group: no capability to detach
BranchGroup" when I attempt removeChildren() on a live TransformGroup.
I created this transform group like this:
TransformGroup tg = new TransformGroup();
...
tg.setCapability(TransformGroup.ALLOW_CHILDREN_READ);
tg.setCap
I'm looking for a tool to make a diagram of a scene graph as generated
by my program. I need this for debugging purposes. Is there such a
thing? If there's any choice on the matter, I'd prefer a no-frills
but simple tool than a monster development environment.
Thanks for your suggestions,
KJ
I think you have misunderstood me. I do not "want quaternions" (I am
quite familiar with them in any case). What I want is code that does
for fixed-axis rotations what MouseRotate does for rotations around a
single point. (I think I can write such code myself, but I would
prefer to use somethin

Arbitrary axis or arbitrary point in space *and* a specified axis?

I need to map mouse-dragging motions to rotations around an arbitrary
axis (not necessarily through the origin). Does anybody know where I
can find code (preferably some extension of MouseRotate or
MouseBehavior) to do this?
Thanks,

Found the answer (in the Archive, as it turns out). Changing
Box box = new Box(0.2f, 0.2f, 0.2f, app);
box.setCapability(Primitive.ENABLE_APPEARANCE_MODIFY);
to
Box box = new Box(0.2f, 0.2f, 0.2f,
Primitive.ENABLE_APPEARANCE_MODIFY,
app);
got
Surely it cannot be so insanely difficult to do something this simple.
I am trying to write code to change the color of a Shape3D object.
The Shape3D object is created using this method:
private Box makeBox(Color3f color) {
Appearance app = new Appearance();
app.setCapability(Appearance
