hey guys, does anyone know how the curvesect sop works? in a way that can be explained in a vop sops? im trying to generate points on intersecting geometery but the curvesect sop isnt giving me what i want..if i knew how it works under the hood i might have better luck… thanks a lot…

You can do this using volumes. Check attached file.
Original idea is taken from Jeff's video.

In attached file I used three techniques:
1. standard volumes (almost replicated Jeff's idea)
2. fog vdb
3. distance vdb (SDF)

You can also use volumemerge or volumemix instead of vdbcombine.

You can also use vdbactivate(Reference and Activate Using VDBs). But I found that It require highres vdb to give proper intersection.

thanks a lot guys helps a lot…actually i realized an easier to get the same result using a simple ray sop.. lol some times i think to much when usually there's an easier way…

and thanks PradeepBarua for your example appricate that
