Difference, union and intersection operation on two regions
Compute the signed distances from points p to a region
defined by the difference, union or intersection of regions
specified by the functions regionA and regionB.
regionA and regionB must accept a matrix p
with 2 columns as their first argument, and must return a vector
of length nrow(p) containing the signed distances of the
supplied points in p to their respective regions.
mesh.diff(p, regionA, regionB, ...)
p |

A vector of length nrow(p) containing the signed
distances to the boundary of the region.
