Hi,
I have to write a big project, a complex simulation engine with a strong 3D
visualization. I have been using Java3D for 6 month, but I cannot size up if Java3D
good for me for such a project is. I must parallel move min. 30-50 fairly large
objects with many vertices and normals and this co
Yes, I've installed Java 2 SDK and Java 3D with the
run-time environment, and the security is taken care
of . . . I think it's something to do with setting
the correct path in DOS.
Cheers for your help anyway.

Hi again,
I am having difficulty in changing the behavior of an object at run time.
Specifically, I have a box which, when it hits another object, changes its 'axis of
translation'. The problem is that when the axis of translation is changed the
object does not continue from its current position
I've had the same problem - what I did was to initilise the Alpha object with a
loop count value of -1 and then the line of code underneath the alpha object
declaration I used the alpha method:
setLoopCount(1)
and this seemed to work, I hope is does for you.

Hi, Akber...
The problem you may encounter is swing components hidding below the
canvas3D (I think, if you encounter any other, please, be more specific). This
is only a problem in the case of menus (as far as you are a little careful
about laying components). In this case you can avoid t

Will this not achieve the effect you want: translate first, then rotate.

Thanks for the pointer.
My point however, was also to get the main on-line documentation to include
the utility classes. I may be wrong, but this should be a simple and
desirable improvement that would benefit a lot of people, (having complete
and up-to-date documentation all in one easy to find

You can get the z-axis direction vector from your rotation matrix (third
column), then translate in that direction. Don't know of a ready-made
function like you're after, but it isn't too hard to implement.
T3D.get(rotation_matrix)
z_axisVector.x=rotation_matrix.getElement(0,2)
z_axisVector.y=ro
I noticed that the constructor
Alpha( int loopCount, long increasingAlphaDuration )
does not set the loopCount properly. Instead, use the explicit method
myAlpha.setLoopCount( int loopCount )
Start the animation with
myAlpha.setStartTime( System.currentTimeMillis() )

you can simply use 2d (AWT or swing) components for your interface (for
example, list boxes, buttons, menus, or whole dialogs). you simply have to
place both the canvas3d and the interface components into a panel or a
different container (you might also want to use two different frames, one

Hi,
I succesfully got the camera to move around a scene, using
RotPosScaleTCBSplinePathInterpolator. There's one small problem however.
The camera moves around OK, but it allways points in the negative z
direction, i.e. - straight into the screen. What I want to do is the
