View Full Version : help with animating an egg and a ball
15-04-2003, 12:38 PM
I'm doin a simple animation with a ball and an egg. I've no problem with animating the ball rolling but I just can't do it with the egg. Rolling on the egg's side(the fatest side) is easy and similar to a ball but not when rolling with the egg's both ends.
I hope you get what I meant.
I fairly new to 3D(using Max4) and what I'm doin now is putting a lot of keyframes and adjusting the position of the egg just to animate a roll. Is there a faster way to do this?

Something like this: Click (http://www.weebl.jolt.co.uk/pie.htm) :p Except in 3d.

anyone any idea??

there could be a faster solution
the first one that comes to my mind is dynamics simulation
put the shape on an incline and run a simulation. if you need to look flat you can adjust your camera to the incline angle and it'll look flat in render

Dynamics simulation...hmm.. looks like a little too "advance" for a novice like me! but never the less something new for me.
thanks for the suggestion!

Now do you really want it to roll like that, end over end?
I would think an egg would actually roll more on it's side in between the fat and small ends, so it would have a procession as the smaller end would rotate faster and the fatter end would rotate slower. I think if you animated it just revolving vertically like that you could then just turn it on the side and move it in time with the previous procession revolution.
That might be more complicated but I guess it depends how close your going to see it and what kind of angles.
Also is this a hard boilled egg or a raw\live egg? Hard boilled eggs roll much differently than raw ones, with the raw ones the liquid embryo gives it an unbalanced roll because it has it's own inertia.

Actually I intend to animate it to look cartoonish, with a little stretch and squeeze here and there. some rolling on its side and some end to end.
u r right about how the eggs behave, will keep that in mind. thanks!
