HELP: Timeshift based on point attribute (activator)

[gaumondchristian]

Hi Everybody,

I would like to get some help/advices to recreate an effect that I find really NICE.

So basically, I want to reproduce the effect created on the first shot of this demo reel: http://softimage.tv/demo-2013/

So what I did was to create an animation on a grid geo, with a scale up and scale down + 180 degrees rotation, and I used a copy SOP to copy this animated grid on the points of an inputed geometry (ex: a tube).

One way I got the effect working was to use a timeshift based on point number (copy stamp with a value like $PT/500). So, this works alright but I would like to have more control, let say with something that "activates" the animation. A way I could say, when the point color is green, or when this object (metaball) is close enough, now activate and do the animation once.

Any ideas are welcome. Also, maybe is there a better approach to recreating this effect?

Thanks in advance guys,

Christian.

here you go

build the mesh you want to "build" and then apply the techniques of this video.

that should give you what you want

Cheers,

Juri

Bryan, this is exactly the kind of approach I was looking for. It is based on the animation of each primitive and it has very light weight calculations.

Thanks for the response. I really appreciate it!

Chris.
