Rectangle distance function
Signed distance from points p to boundary of rectangle to
allow easy definition of regions in distmesh2d.
mesh.drectangle(p, x1 = -1/2, y1 = -1/2, x2 = 1/2, y2 = 1/2, ...)
p |
A matrix with 2 columns, each row representing a point in the plane. |
x1 |
lower left corner of rectangle |
y1 |
lower left corner of rectangle |
x2 |
upper right corner of rectangle |
y2 |
upper right corner of rectangle |
... |
additional arguments (not used) |
a vector of length nrow(p) containing the signed distances
