Incrementally mesh a changing level set

[Steven Tondeur]

Hi all,

does anyone know if it's possible to only mesh part of a grid using openvdb? E.g. in a voxel sculpting scenario where you're only adapting (e.g. boolean operations (think: remove/add material) ) a small part of an existing grid, it would be good if you didn't have to remesh the bulk of the grid that hasn't changed.

I searched around for a method that could extract part of a grid to see if I could make something myself using low-level operations, but I didn't find any. Am I missing something?

Kind regards,

steven

If you directly use the VolumeToMesh class, you can set a mask for what to convert to polygons.
