[ODE] Re: tokamak vs. ODE.. interesting to know

[Rikard Herlitz]

The response I got from tokamak whas that an commercial license would cost
about 800$ ... although they had not quite set a final price yet...
for non-commercial use it's free...

there is a sample that comes with tokamak that sets up a simple car, using
their sensors to shoot rays vertically down from
each wheel...

couple questions...

What does takomak cost?

How is it for simulating vehicles?

The info is a bit sparse on there site.

I've made heavy use of both ode and tokamak in one of our prototypes for
xbox...

tokamak is comparable to ode when solving with ode's user-made faststep
implementation, the iterative solver...without it, ode is accurate but
impossibly slow for use in games...and the accuracy difference is not
noticable att all anyway(using appropriate amount of iterations offcourse)..

*ode pros:
has spaces(simple or hashtable), that can also contain other spaces
hierarchically.
easy to extend with your own geoms, or use another collision detection
engine(like opcode).
alot more joint types than tokamak

*tokamak pros:
bodys go into resting state automatically(get disabled/enabled). in ode you
have to do this by yourself...
easy to use..
has a great sample of ragdolls, with joints and bodys setup, that you can
make use of...neat to have when you not have the physics-setup tools that
come with havok...
it's a bit faster, probably due to better collision detection...
joints seem more stable than in ode

lot more to say, but hey, who's got time...
