Good day!
I just would like to ask if I will be able to create a behavior that will awaken when
the left mouse button is pressed not only my Mouse Keypresses.
Thank you very much!
Like this?

mouseEvents = new WakeupOnAWTEven
Paul,
I think people would respond better to you if your e-mails weren't
formatted like advertisements / spam. If you are responding to someone
try just a normal reply with an answer to what they asked.

Correct, exception for this line.

hehe I could see how that could be confusing. All my Path code is in an
alpha state, which means its in the "change some inputs and see how it looks
stage". The last test I ran was to use a texture that was a segment of a
long curved path, and the texture was 8 times longer than it was wide. So
Are you defining "intersection" as the intersection of the volume(s) or the
geometric intersection caused by the polygons of the two objects
intersecting?

Hi
I wonder if the inverse of a transform really is correct?
The rotation parts is correct but the translation
seems to be screwed up a bit.
Anyone experiencing the same?

Hi all, I have notice that when I run the following code scale value is
reset to 1.0. Is that the expected behavior or should keep the scale
value before rotX was run?
tg.getTransform(t3d);
t3d.rotX(Rot);
tg.setTransform(t3d); <- Here scale have been reset to 1.0

Most likely the inverse is correct, since this is a basic function and an error
would lead to lots of other problems.
However, there are a couple easy tests you can do to check. Multiply the
inverse by the original transform. This sho
I got a very similar message with de SimpleUniverse class.
When I asked for his LocalToVWorld transform, I got the could not change

I think that auxiliar classes like Sphere, SimpleUniverse,etc are

or these functions aren't available
If you want to preserve the translation and scale components of the
transform, you must
do that:
Transform3D mul = new Transform3D;
mul.rotX(Rot);
t3d.mul(mul);
rotX set the non x-traslational components to unitaries.

Hi, David! Thanks.
Maybe it can helps you.
You must fix the number of times you want to wrap the texture over the road
(for example, lineroad of 1 m. numWraps=lengthRoad/lengthLineRoad, for a 50
m. road is 50 wraps.
so you can do this:
tex.x = 0;
tex.y = (length*numWraps)/(numPointsOfRoad-1)
Hi,
Check out www.javagaming.org, they are running a competition for the best

for the first person shooter shown in the keynote.
Humid is built entirely on Java and Java3D.

Hi Justin..
Thanks for your reply...
I thought that immediate mode might be the answer.. I'm getting okay
performance with renderOnce(), so I'll probably stick with it for now.

Groups manually... It's given a substantial

We have a viewable range of, well anything up to 12800 meters with
