Umm..if Blender can do it....we can do it better....right? $:-\$

Don't know how it compares but I used part of this one once. I like the wheel turn op, very handy. The results look pretty good in the tutorial.

Yeah I saw that. He posted it everywhere once he release it [vimeo, si mailing list, xsibase, etc.]

But, that's using traditional rigging setups. I wonder in what ways ICE could improve the setup or performance?

dont want to sound offensive, but, whats wrong about "traditional"?
I just loved how simple that car rig by Andy is to set up... I had no clue RBD was so responsive and well implemented in SI.

Plus if you are comparing performance you should really consider that the car in Andys tutorial has a gazillion polygons vs just a few polygons in this blender example.

Oh and you could always the wheel turn op in ICE

I think it could turn into an interesting experiment/project. Not because ICE could do things better than "traditional" methods (although we won't know, until we try, obviously), but basically because the idea of any sort of rigging in ICE could definitively benefit from some more public attention...

It's not physics-based, but here's an attempt at aligning a chassis on uneven ground. It's just an experiment I made quite some time ago, but never had time to go back and develop. It might be useful to someone as a starting point (or then again, maybe not).

Thanks. I was thinking along the same lines as well. It seems to perform quite well. I remember ChrisTC uploading a video about this topic some time ago as well. I dont think he published the ICE Tree though, cant remember. But, ChrisTC's rig was like doing some real physics calculations and stuff if I remember.

Oh well, so many projects, so little time.

Anyone here who knows of a nice "software agnostic" written tutorial
about the actual math/physics that should be considered in such a physics based car rig?

Hirazi, I was gonna go the same route, but figured, heck I just want something that is easy to setup and animate.

Best bet would be something for games. Unity might have something. I remember a Car Racing Game for XNA (C#).
I forget how "physically correct" this was: http://create.msdn.com/en-US/education/catalog/sample/racing_game.

This might cover some of that. http://www.amazon.com/Professional-XNA-Programming-Building-Windows/dp/B005GNMGDA#reader_B005GNMGDA Handling Looping, Spring Physics, Collision Detection
