[SOLVED] Controlling fractures with particles

[Cake Kid]

Hello,

I am, unfortunatelly, still beginning noob in Houdini and I would like to kindly ask you guys for a help.

The effect I'm trying to achieve is:

   - There are two objects in the scene: 1., a cube, which is fractured into pieces (voronoi) and 2., a sphere, around which the pieces should orbit

 

I'm sure there are many ways, how to achieve this, but the only way that I found is controlling the fractures with particles. Basically, there are 3 stages of the motion: 1., cube is still, not moving, 2., cube fractures, starts orbiting around the sphere, 3., pieces stop orbiting and fall on the ground (acting as RDB objects).

I got to a point where my cube is fractured and every fracture has a point in the centre. I don't know how to use these particles to drive the voronoi pieces though...

 

I'm a bit stuck, trying to come up with something smart, but I'm just running in the circles... Could you guys give me a hint, how to achieve this?

.. I'm attaching my .hip file of what I have so far, to make it more clear..

 

Thank you

Check out the procedural text tutorial. You should be able to copy the broken pieces to the particles.

Oh I see, thank you very much.

Two "foreach" nodes didn't work for me, so I made it work with only one foreach node and a copy node.
