north = -Z
forward = -Z
But it has dawned upon me that the standard seem to be:
north = -Z
forward = Z
Can anybody confirm this?
What do you guys use?

sorry if it sounds stupid, but doesnt forward depend on the direction

i would have thought that forward is a vector that changes, whereas

find objects like fences with it when it picks the holes in such an object
and therefore doesn't detects it.

Michael is right. For such things maybe it's better to just use simple
bounds collision detection. Depending on the form of your avatar, you may
use a sphere or a box, or a collection of those if you really want to have a
very precise collision detection (i.e. sphere for head, boxes of various

You should update your directX AND after that your video drivers. Sometimes
that fixes problems with java3d. Or switch to the opengl version. In both
cases it's a good ideea to have the latest video drivers installed. Somehow,
java3d doesn't work well with the "stock" Microsoft drivers provided at
Thats an possible solution but it doesn't works in complex scenes either.
Imagine a object you can collide with (e.g. the wall of an house) and you
can stand onto (its roof). Here only the first case should be detected as
collision ( and in this special case uing the ArmingPath doesn't works).

I think it's working pretty well for the case you described too ! That
simple collision detection scheme I presented shoud be used to prevent
movement in a specific direction. So, if the wall is in your front, you
cannot go further. However, if you're standing on the roof of the house, the

Some feedback, I ended up using suggestion no. 2. It seems to work pretty
well, and considering the amount of geometry I have, the performance I think
is pretty good, it takes about a couple seconds to render every time I
change the geometry. Thanks again! Appreciate your help. Now I'm looking at

The calculation is done on a cluster (because of the big amounts of data).
Java3D is used later to visualize the results.
