Is there any solution to this problem:
I have two transform nodes in a scenegraph.
Neither of them is ancester to the other.
Is it possible to get the transform between them?
All transform nodes are expected to be affine.
Any help is appreciated

Title: RE: [JAVA3D] Difficult matrix algebra problem
If you have the transforms in the global coordinates, you can use the inverse transform to get the relative transform.
Take the inverse of one of the global transformations and multiply with it the other.

You mean like this or the opposite mul:
solution.mul(M|1.invert(), M2);

There is a Java3D NWN models loader here :
http://nwn-j3d.sourceforge.net/loader.about.php
I not sure, but I guess you can load geometries with
key frames by using LWS LightWave or VRML models.
I am working in a character animation api for Java3D
but I had a special approach.

Check Jeremy's reply. It was more clear than mine.
Basically the situation is as follows. Assume you have transformations A and C and you want to know the relative transformation B between them.
You know that:
AB = C
When you multipl

Hi,
I am using Java3D/OpenGL with a NVidia Quadro FX500 in dualView mode (two
monitors).
I have a problem when I extend my application's main window on the two monitors.

No, you must modify the clipping volume by calling the setFrontClipDistance()
and setBackClipDistance() methods of your View object.

Java3D is seeing the graphics configuration on both heads of the card,
create an array of graphics devices (head[0], head[1]) and add components
to them. I can send you example code if you cant find it anywhere.

Yes, if you have time to spare sent it to me an example code would help a

Does any body have a good linear matrix algebra book they want to
recommend that covers subjects like below? I'm just getting back into
this stuff and need a refresher from my college days. It's amazing how
much of college you forget when you don't use it. :o(
thanks a bunch,

Hi,
This might sound stupid, but I need help texturing a box!
I want 2 different textures, one on the front and one on the back,
In order to simulate a wall, in a house.
Whats the best way to achieve this, one image file containing inside +

Hi everybody
I want to insert Canon in the canvas that can rotate around a fix

How could I do? Import some support file to show or I must create it
all in Java3D.
Thanks in advance..

Use 2 texture files.
Create a Appearance for each face.
Apply the appearance for the correct side in a Box
object:
box01.getShape(Box.Front).setAppearance(app1);
Do not forget to set the capability bit
ENABLE_APPEARANCE_MODIFY of your box.
read the javadocs Box, Shape3D, Appearance, etc...
