SPGrid for adaptive smoke simulation

Recommended Posts

I saw this was rolled out at siggraph asia 14 but haven't heard anything about this so far

 

http://pages.cs.wisc.edu/~sifakis/project_pages/SPGrid.html

 

There's some definite comp-sci wizardry happening here involving sparse memory paging that's rather difficult to comprehend fully.

 

They compare it to VDB and atleast in the access test results they showed it has quite the speed improvement (What looks to be 10x) in access.

 

 

 

Maybe we'll see a VDB-topper for volume data/simulation using techniques like this in the near future?

Thoughts?

Looks really cool.  That would probably be really useful for games.  I may be wrong but is that more of a way to visualize a sim rather than actually compute it.

The paper also includes their approach to simulation using the SPGrid structure.

Interesting, I didn't read the paper, I just watched the video.  I am curious how it would work with a moving camera or moving geometry.
