Hi Alex,
Unfortunately I don't have any java sample code handy, but I had written a
small cpp class that would align an object with the poly that it collides
with. In order to "groundClamp" without any sudden changes of the model's
orientation when you drive across polygons, you would need 3 down line
segments. To get started, you could use 1 line segment and use the polygon's
Vertex coordinates to align your self. (This wont look right when you go
from one poly to the other, because there will be a sudden change in the
model's orientation; but not a bad place to start) I have attached a .cpp
and .h file that uses a VecMath library similar to Java3D's. I hope this
help you out a bit,
Take Care,
