Silvere,
I like this book for those sorts of problems:
http://cs.smith.edu/~orourke/books/compgeom.html
It's mathematical but very thorough.

Adrian,
I've just finished reviewing the work of the copy editors on another 2
chapters of my book this evening... so you can't expect an unbiased option!
;-) My book should be available in a month or two (depending on how long it
takes to typeset). Only a year or two behind schedule! ;-)

What do you want to know? I've done alot lately with mixed-mode and

Hi all !!
I' ve been working with several modelloaders like Starfire 3ds loader, SUN OBJ loader
or VRML loader. I wonder if it exists a loader that could load a possible animation

converted to scenes with Behavior'

I have an applet that switches between multiple Canvas3D and only one with the action

not visible). But this wo

If you are able to create the geometry of the objects yourself then you
could use 1 geometry array for all of the objects.
In the case of 200 cubes:
Use a QuadArray with 200*6*4 coordinates (numCubes*facesPerCube*coordinatesPerFace)
.
Use Transform3D to perform the rotations and tr
I have read various articles on performance which mostly

That's true, we started working on importing animation information with
our loader earlier this year. Unfortunately other work priorities
forced us to suspend working on that. It's possible the work on that
will resume in a month or two, but no guarantees.

I intend to add animation support "soon" in my Milkshape loader. It's on
the TODO list.
Milkshape can import 3DS models and save them out in native format. If
you've got a 3DS model with animation data, load it up into Milkshape and
see if the animations are preserved. Or send it to me. None

Hi all,
I have updated the Magellan Spacemouse java class to read buttons. However,
when I set the the Sensor reading, I cannot call upon the buttons array from
the behaviour.
In the Deivce class I have something like:
case BUTTON1:
button_down[0] = BUTTON1;

Just a quickie,
I'm adding in some button controls for a Magellan. i can't decide whether it
is better to place the button's effects in the Device class or the Behavior
class? If I was to use the Device class, I have immediate access to the
right methods, it's also easier to apply translation eff

Fredrik,
Where is your view platform positioned? It is highly likely that you
are "inside" your object and won't see it. Be careful with your
clipping distances too.

I've been using it for years and it's very good, the new version is
good
too. If you're doing a lot of VRML coding it's worth it. But it's not a
graphic
app, it's a text coding one but does check syntax for you and command

Dani,
You should not be using this form in an applet. Unless you've bypassed
applet security an applet can't load files. You should use a URL
instead:
URL url = new URL("models/testfile.3ds");
Scene s = loader.load(url);
