Divide volumes represented by level set grids into multiple, disjoint pieces by intersecting them with one or more "cutter" volumes, also represented by level sets.
If desired, the process can be applied iteratively, so that fragments created with one cutter are subdivided by other cutters.
- Note
- The incoming grids and the cutter are required to have matching transforms and narrow band widths!
- Parameters
-
grids | list of grids to fracture. The residuals of the fractured grids will remain in this list |
cutter | a level set grid to use as the cutter object |
segment | toggle to split disjoint fragments into their own grids |
points | optional list of world space points at which to instance the cutter object (if null, use the cutter's current position only) |
rotations | optional list of custom rotations for each cutter instance |
cutterOverlap | toggle to allow consecutive cutter instances to fracture previously generated fragments |
Return a list of new fragments, not including the residuals from the input grids.
