Howdy!

I'm trying to build a custom microsolver to be used in FLIP sims, and one of the steps is a particle neighbor search. I'm using the GEO_PointTree class for this, but building the tree and querying it at every time step has been very expensive.

Is there a best practice of when to rebuild the tree in DOPs? In SOPs I could postpone updating it unless the input changed, but my assumption here is that particle positions are always changing, since the simulation is iterating forward.

Or maybe there is a better suited data structure? Feels like I'm missing something basic here.

Cheers!

After applying Mac Yosemite's latest update (to 10.10.3), I can't get Houdini to run anymore. The production build doesn't install successfully either.

Today I was able to install the daily build (14.0.304), but the behavior is the same as with previous releases: the application doesn't launch.

In the Console, this is all that is logged:

I'm wondering if anyone had a similar problem or has any idea of what might be causing this.

Thanks!
