Arguments:
- isovalue[%],_metric or
- isovalue[%],[metric],_method
Description:
Compute the unsigned distance function to specified isovalue, opt. according to a custom metric.
metric can be
{ 0=chebyshev | 1=manhattan | 2=euclidean | 3=squared-euclidean }.
method can be
{ 0=fast-marching | 1=low-connectivity dijkstra | 2=high-connectivity dijkstra | 3=1+return path | 4=2+return path }.
Default values:
metric=2 and method=0.
This command has a tutorial page.
