If I understand it correctly the get method assigns the point to the

Hi there,
I am having a problem with my PickBehaviors. I am using a Scale, Translate
and a rotate behavior and they work fine. But they do not satisfy my needs.
For example: When I rotate an object, it rotates itself around the origin.
When I scale an object, it scales but also moves to the or
If I understand, you need to use r = 0.3f instead. No
offense, but most of your problems have nothing to do
with Java3D and are out of context here, don't you

In the image I sent, there is a TransformGroup as the parent to each ViewPlatform.
This TransformGroup defines the position and orientation of the "camera". In my
sample, this transform is in the World/Universe co-ordinate frame.
So, if you want two cameras situated along the X axis, b

Unfortunately, like everything about 3d programming, there is no easy
answer.
There are many different techniques, but as a simple explanation the program

Hi Andy,
If all you want to do is make r, xc, yc, and zc into floats, but keep v as an int
(which you need to do for your array declaration), just cast the calculation of v to
an int:

int v;
bvol = ((xc+r)-(xc-r))*((yc+r)-(yc-r))*((zc+r)-(zc-r));
v = (int) (bvol*200
How do I define the location of the view? DO I define a vector to place it ?

I assume you're trying to run the program as an

You can't really run Java3D in an "emulation" mode. That would really
mean that Java3D would have to include software-only versions of all the
