RODEO

[Chenarch]

Hey all,

Can someone explain to me in a sentence what the values mean that I have highlighted in this snapshot of the RODEO Advanced Tab... ?

Thanks!

Richard,

Min Subframes

If this value is greater than 1, Rodeo calculates position of object in between frames to avoid going through a floor for example if in fact it does so between 2 frames.

For Rodeo to see what happens inbetween these two frames it needs to calculate subframes. If Rodeo is missing collisions this value must be increased. Default: 10 subframes.

Max Subframes

Where there are severe object collisions that violate the allowed Penetration and the allowed Link Violations settings, Rodeo will than start to increase the subframes to get a correct solution. This can greatly slow down the simulation. To limit the time to compute the solution Max Subframes impose a maximum number of steps between two frames for the engine. We risk an imperfect simulation by doing this. Increasing the max Subframes value will in general yield better results.

CG Solver and Solver Iteration

I'm not sure about this one. I think it's the number of repetition the solver will use to attempt a collision detection. As I remember, the CG solver is an alternative solver giving a more exact solutions but might be slower...?

Well I hope it shed some light into the dark...

Thank you, again, Richard.

Sometimes I find Rodeo puzzling. I can "stumble" on to the right settings

and get excellent results, then if I change one little thing, suddenly the moving objects change radically (vibrate in place or something odd)

and I'm confused because don't understand the micro-happenings of each parameter...

Anyway, learning curve!!

Cheers,

Richard
