Render nParticles as Water without Brep

Hello,

I am looking for a way to render nParticles as a water surface without creating a mesh first.

The image represents just a sample with less particles. In final there will be more than 70.000.000 particles… So Meshing them first is really slow.

What would be the fastest way?

Thanks for your help!

I may have misunderstood, but isn’t VRayMetaball what you’re looking for?

Not really, because with Metaball is also a precalculation neccesary.

I’m looking for totaly meshless method as described here in Chapter “Meshless Surfaces from Point clouds”
