I'm after the most efficient/robust way to keep the water line of a sim as clean as possible.
I frequently find myself wanting to get rid of the faces that touch/intersect with collision objects.
Im trying to use the camera filter, ‘Regions’ tab of ‘Particle Fluid surface’ node, with a camera posed looking down at the surface, but i think i miss a normal angle threshold of some sort, since the camera method may open holes on the waterline even if polys are facing the camera straight in the eye.
I tried merging collision objects into the surfaced flip network and boolean-subtract it, and the result gets me almost there, but some frames generate a huge list of ‘Crossed boundary (unshared) edges in solid B: …’, which takes the mesh to a total loss for that frame.
The thought im having is to create a VOP net that checks if there is a poly normal pointing towards the collision object, infect it somehow, and blast all infected.
Any insights are greatly appreciated as usual,
Thanks!
Al
