hi,
May be that is true...i ll have to brush up my
concepts of translation and rotation matrix...
But there should certainly be a mathematical method to
calculate all the translation matrices for a given
collection of TransformGroup so that we could
Translate the collection to a desired point in
Yet, I'm not sure I've understood your problem.
You have a collection of TGs, each with a different position/orientation in
the 3d space.
You want to translate this group of objects in a certain point in the space
without changing relative transformations between them.
You have two ways: one, as ju
Multiply all the transforms of the transform groups. From the resulting
transform you can extract only the translation component.
Cheers,
Florin

Hi All,
I am working in a rack control and monitoring systema here at CERN that
will have to deal with around 400 racks full of electronics. I was
thinking about adding a 3D interface and I saw some kind of example that

Hi Bobby,
This sounds like a really, really, really cool toy!!! :-)
Your suggestion triggered my interest because you mentioned registering
real images against a virtual scene. I am currently working on an
application to do this. I am using code by Reg Willson (written in C)
that calibrates a "Ts

Assuming you can get the X,Y,Z and course, pitch, roll of the real camera,
creating the overlay would be pretty easy. There are numerous 2D overlay
packages for Java3D (just dig through the archives or look at j3d.org). All
you need is a Texture in the scene oriented with the view and scale
Mark,
It is a great looking project. It is good to see Java3D getting used in some
real applications (not that all of the hobbyist aren't nice). I wish you the
best of luck in marketing it.
Hopefully in a few weeks I will have permission to put up some snapshots of
my Java3D application.

How can I add a texture (jpg, gif) over my scene background..
I create a Background object, but it don't have appearance methods..
Anybody can give me a example code...
Thank you
