v@P += v@v * dt;
writes to the position attribute of the points `v@P
. Whenever position is written to in this way, the AX PointExecutable` will move (re-bucket) points in PointDataGrids.float@density
would imply a float volume called density. is
written to. This means that the final blended result, stored insurface_a, will only be updated in
surface_a`'s topology. Should we want a combined blend of non overlapping areas of both surface a and b, we would need to activate a's topology with respect to b first.
