Thanks for your answer. So I have two more questions:
I currently use Starfire 3DS loader. It builds the scenegraph like this (for a 3ds
model composed by multiple objects):
BG (Main model BranchGroup)
|
/ | \
/ | \
/ | \
/ | \
/ | \
/ | \
BG1 BG2 BG3 ... (For every object)
| | |
| | |
| | |
TG1 TG2 TG3
| | |
| | |
| | |
S1 S2 S3 (Shape3D's containing geometry /
appearance of every object.
a) I want to add animation to the objects separatly, such as Interpolators. For
RotationInterpolator's, they can be added to a single object adding it to its parent
TG. But the rotation is always done around the origin. Is there any way to rotate them
around an arbitrary point ?
b) The position where every object is located can be calculated like this:
For every BG1, BG2, etc:
BoundingSphere bounds = BG1.getBounds();
double radius = bounds.getRadius();
Point3d center = bounds.getCenter(); // Gves the center of the
sub-object.
I want to add a PositionInterpolator to every object (to mo¡ve it from out of the
scene to its position).. This works fine, but the objects move all at the same time. I
want them to enter in the 'scene' one after another (f.ex. an object enters and
arrives to its position, afterwards the following objects does the same).
How can I implement this ? Do I have to manipulate Alpha parameters ? How ?
Thanks in advanced !!

I am pretty sure that there is currently no loader capable of loading
animations. The problem lies in documentation of the different animation
formats as well as the fact that Java3D really has no simple way of
animating a model like in 3D Studio or any of the other animators. The
RotationInterpolators rotate the entire model; to duplicate the effects of
an animated character you would need to break the model apart down to
individual body parts and specify animations for each of those. And since
only one Interpolator can target a TransformGroup, the hierarchy of
transformgroups needed for just one character would be impossible for a
loader to generate. If you want animations for your programs you will
probably have to implement your own keyframe or skeletal animation system.

P.S. There are also people working on integrating Java3D and VRML. Check out
