From viewing the houdini extrapolate docs and an old question posted on the google forum it appears that maskSdf only changes the values of A with respect to match interior distance values of B? |

C = tools::maskSdf(A, B)
extends the SDF A, into the mask defined by B via fastsweeping, creating essentially a unioned topology of A and B in C.
How do I get C to reflect the unioned topology surface of A and B? When I view C in vdb_view the "surface" view shows only A. Only the "data" view shows the broader B topology.
I ask because I am trying to create a mesh of C via volumeToMesh(C), but the output mesh again only describes the original A SDF, ignoring the extension in to B. Isn't the purpose of maskSdf to create an extended SDF / surface?
I tried tools::levelSetRebuild(C) before vdb_view, but that seems to only have erased the extended topology of B entirely from the "data" view.
Thank you for pointing me in the right direction!
