Accessing Bullet Impact Data in DOPS

[jamesearnest244]

Hi,

 

I have a simple Bullet sim with an RBD Packed Object node. I would like to create POP groups based on the points' collision data. For example, group the points that have collided with the ground plane more than once.

I know I can access the impact data with a SOP Solver connected to the Bullet Solver, but I'm not sure how to use the data there to set up the POP groups.

Very simple setup attached to make it clear.

I'd appreciate any help!

Thanks!

Hi,

this is a file I made with simple example to show how you can use a dop data with Dop Import Record sop.

Thanks very much! But this isn't quite what I'm after. I want to use the Impact data in DOPS, not in SOPS. I want to create POP groups of points in the RBD sim, based on the number of times they've collided with the ground plane.

Do you want create group of rbd objects?

e.i. if a box in your sim impacts 3 times with ground plane object that box should be include in a group. Is that your goal?

Basically yes, but I'm using packed RBDs in Bullet, so we're talking about grouping points, not RBD objects.
