Creating intersection curves between 2 objects with VDB

[quinton]

Hi guys,

 

I have been trying to obtain a set of points around the intersection of 2 geometries using VDB. Does anyone know how to do that? Say if I have a sphere intersecting a grid, the end result should be some sort of a ring. 

 

I thought perhaps someone here might have done something similar already but I couldn't find it in the forums.

 

Thanks in advance!

 here's one way.

Thanks, I didn't think of doing it this way.

 

Another method I tried is to use vdb to obtain a closed mesh of the geometries before using a cookie sop to get an intersection curve.
