transfer animation from point to group

[papicrunch]

Hi,

I m trying to transfer one animation to bunch of shattered pieces in a procedural manner.

For the moment I copy the animated data on some points and then i use a foreach group to retransfer them.

I would like your feedback to optimize the method or if you know of another way simpler, faster for such effects ?

Thank you,

Thomas

if you use attributes rather than groups you can do everything in the 'apply data' foreach in a single vopsop. this makes for a big performance gain.

in this case, with simple geometry, its only 100% speedup, but with hundreds of thousands of pieces and millions of points on the animated geometry, this method works in minutes where foreach would work in hours.

here's your same file with a vopsop replacing the foreach. i colored the nodes i created to do this in pink (only ~3 more nodes to make the appropriate point attributes for the vopsop)

btw- cool animation

yeah very cool brianburke,

I was convinced that there was a way in in vop but the use (and concept) of matrix are still obscure for me. As you say with a lot of pieces the speed gain is amazing !!!

Thank so much !
