Can PBD Fluids be created using Houdini's PBD?

Hi,

 

I saw it described here:

http://mmacklin.com/pbf_sig_preprint.pdf

 

 

Since H14 already has point based dynamics, can it be used for fluids? If so, are there any examples of it out there?

 

Would this provide major speed ups over FLIP? Would you be able to max out the performance by using OpenCL DOPs as I see this implemented completely on the GPU. Or is it a matter of the default PDB tools in Houdini to be GPU accelerated in the first place?

 

 

Thanks :)

Yup, I recon so.  If you look in the VEX header file for the PBD granular code there's some functions already written for SPH type fluids - density estimate, lambda calculation, etc.  I was having a look but work is distracting me now! :D

 

As for speed ups, I'm not sure.  But it would prob be better than FLIP for small-scale sims where surface tension is needed for the look.  And Nextlimit just added it in Realflow as 'Dyverso' and they claim major speed ups over previous implementations, so might be worth a look!
