View Full Version : Christmas commercial: Tree-Rig

12 December 2007, 07:36 PM
for a small christmas commercial I wrote a script to create some glitterballs at a christmas tree. The balls are rigid bodies and move with that tree. The tree itself is a hair and a brush, behaving dynamical as the follicle moves.

Hope you like it, but consider: It is only the start ;-)

I realized that it works best under IE. I not tested FF yet.

The only thing that bothers me with the rig is that the trunk seems a little too flimsly for me. The tiny branches look great, but I think it would look better if the trunk was just a little sturdier.

I really like it. I did not notice the the trunck being too skinny/flimsy. I was really hoping one of the ornaments would fall off. I know it is just a rig, I am just letting you know what I wanted to see.

Hey, the rig looks fairly simple, i agree with everyone else a little thicker trunck would sell this better and if u like it the way it is at least model a tree base holder to help believe that its that strong to hold the tree together as it moves.

NOW if u want be a awesome rigger (not saying u arent now ot cant be) when u move the tree and the ornaments move, you should have maybe one or two fall off as a result of a jolting move, could be an expression or a dynamic relation to the rig. But i always say things that happen natural are awesome, even though animators disagree, also want control control control.

My thoughts hope they helped!!!

I can only say: A broken ornament is not planned ... But I know what you mean. It should be fairly simple to create a script to let them fall down. They are simply rigid bodies with an constraint.

Okay, I have done the next thing: The movement of the christmas presents and a simple simulation of the loops (Is "loop" the right english word for this?)

The next step is to create a script, that duplicates the loop, placing it correctly and connecting it to the present.
Additionally I try to model some of these stiff loops...
