View Full Version : "Faking" a rolling dice hardbody simulation

Hey,

okay, this week a freind of mine at art school needed a sequence witha dice beeing shot and rolling over a table, with videos projected on each of the six surfaces.
Okay, Maya's got hardbody simulations, we only got MD, and its long and tedious to setup, but since this was a quick and dirty job, so a little invention was needed.
The solution: we used "gravity" as a motion modifier to get the y-axis damped bouncing of the dice, and the rotation around some HPB-axis during each bounce of the dice until it laid still was just hand animated.
The result was pretty cool and realistic, and the great thing was that I could place the dice exactly where we needed it in the last frame...which is hard to do if You rely on exact physical simulation I guess.
The trick is that "gravity" did all the y-axis stuff for us, so I had only two keyframes to set for the x/z-motion of the dice..voila !
15 minutes of work and another 30 minutes to tweak it to perfection and set up multiple cameras.

LW rules !

quick tut - quick tut - quick tut

and the crowd chant for a quick tut


:D

You dont need a tut for this - its so simple! Thanks mate: just tried it, took me < 5 minutes to set up (a ball instead of a dice).
nice one!

He's right! But here's how it's setup!

I need to play with the motion modifiers more!
