Hi there,

i'm totaly new using Houdini, hope someone can help me...

I'm looking out for a fast way to render a water surface based on a particle simulation (apprx. 70 000 000 particles).

The simulation is done with an external tool and creates a sequence of .vtk files with details for id, density and velocity for each particle.

This sequence is converted to .vdb via paraview (I found no way to import them directly to houdini)

In houdini, i create a file node to read the files and they are displayed as points.

Now i want to convert them into a surface mesh or better (becuse faster for rendering i think) to vdb.

Can someone help me with this?

Find attached one of the .vtk and .vdb files I'm using for my test.

After loading your VDB file, use a Convert VDB Points sop. Choose the "Extract Points from VDB Points" conversion mode. Then append a Particle Fluid Surface node to get geometry you can render.
