Yes,
mainTransformGroup is a TransformGroup.
Then I add mainTransformGroup to my mainBranchGroup

Thanks for that.
In the test file, do u add the buildWall() method to a
branchGroup?

Here is my buildWall() method:
carreauSize is the size of my texture (n*n) (could be
improved to (n*m)
p1 and p2 are corner point (opposite)
You can see the result at:

You could create a room in a 3D modeling program such as
Maya and export
it to a file (such as VRML) and use jX3D to load it into
memory. If you
don't have money to buy such a program, you may want to
download
Blender, a fairly decent freeware modeling
program.
Or you could create a Box object and scale it to an
appropriate size.
Creating geometry by typing in a lot of datapoints is very
painful and I
would not recommend it.
