Hi,
I try to integrate the recent release (2.7) of Ageia's PhysX engine into
an OpenSG 1.8 project. So far I stumbled over several differences. I have
the feeling, that my implementation is not really correct, as I experience
"strange behaviour" of certain objects in the scene.
It would be great if someone who already successfully integrated PhysX
would share his knowledge with me and verify the following observations I
have made so far during my project.
1) Coordinate system differences
OpenSG and PhysX coordinate systems' use different axis orientations.
While the coordinate system in OpenSG looks like this
z
^ y
| ^
| /
-----> x
the coordinate system in PhysX looks like this:
y
^ z
| ^
| /
x <-----
2) Object scaling
Objects instantiated in PhysX with default scaling are twice the size as
their OpenSG counterparts. Here an example:
Box in OpenSG | Box in PhysX
-----------------------------
1,1,1 = 0.5,0.5,0.5
Are these observations correct?
Thanks
Philipp
PS: I think it would be nice to make my experiences available as a
tutorial for other interested OpenSG users. Is there a place on the OpenSG
wiki for this kind of "hot-to"?
