Yeah DIMO, that sounds like a good point. Fun fact of the day: the same, IMO, goes for Realflow, the water simulation plugin. It’s horribly slow, and you always end up wanting to change something more or less tiny, only changing the result is horribly slow and hard, because, hey, the water is simulated… all you can do is change the start-parameters…
So yeah, all-out car-simulation is not neccessairly the best workflow in the world. Personally I quite despise the idea of being locked into that trap again.
Then there’s keyframing… it works I’m sure, but it’s gotta be tedious to animate all the subtle chassis-movements? The way tires spin and shake when they loose grip for a second… it’s certainly a lot to keep track of, and maybe something could be added to alleviate the animators from that task?
A thought comes to mind… a… a hypothetical interface that might work. Or maybe not. I’ll just throw it out here and see if others finds these sort of “imagine how it could be” things interesting:
Okay so you’re animating a car-dummy around, you’d be rotating the front wheels, making sure not to drive the dummy far into the ground, or up so it takes off. It’d be the keyframing you’re speaking of DIMO, so you get the weight of a car moving around, but without messing with the shocks of the chassis, or animating the shockabsorbers, or anything like that. Just the basic car-movement.
Then you run The Plugin, and it matches the wheels with the movement of the dummy. Then it matches the chassis to the wheels. That could give you the tiny vibrations and shock-absorbtions and such by way of simulation, without giving up the ability to keyframe the basic movements?
If you want more vibration as it, say, goes offroad, reset the simulation, and animate the Rough Surface (or whatever :)) parameter so it jolts up at the right time. Rerun the simulation, and now the car starts vibrating more as it hits the rocky ground. Depending on the settings of the Shock Absorbance Quality parameter If it’s a four-wheel offroad car, the wheels would just shake I suppose, the chassis staying flat. A sort of “bumpmap” for the simulator, so you wouldn’t have to model in all kinds of nasty details geometrically.
Just a thought… idunno… lots more to detail out of course, and many pitfalls in that idea I’m sure, but that’s why I keep repeating it’s just a thought :rolleyes:
Btw I’m all for the idea of simulating the wheels and chassis and whatnot through Reactor. As it’s been pointed out, it likely has all the physics-calculations anyone could ever dream of.
Anyway, I for one fear, as it seems DIMO does as well :), the idea of a hardcore vehicle-simulation. But maybe something inbetween could indeed be thought up… something designed from the grounds-up to be used by animators, with an anxious art director right behind them asking for the tiny weird changes they always seem to be asking.
I hope I’m not derailing the topic by bringing in these theoretical “what if it was made like this” postings.
