Cells
|
||||
-----
|
||||
|
||||
Not yet documented
|
||||
If nothing is declared, it just uses all the visible cells (or all cells on closed manifolds),
|
||||
and the distances are measured in tiles.
|
||||
|
||||
You can change this as follows:
|
||||
|
||||
* `-sag-creq x` -- use x tiles which are geometrically closest to the center (or a bit more in case of ties)
|
||||
|
||||
* `-sag_gdist x` -- take geometric distances instead, 1 absolute units = x units
|
||||
(this will be rounded to integer because of the limited precision of some methods)
|
||||
|
||||
* `-sag_gdist_dijkstra m` -- compute actual geometric distances if <= m steps, use Dijkstra to compute larger distances
|
||||
(used in geometries like Solv where the distance computation does not always work for large distances)
|
||||
|
||||
* `-sag_gdist_save filename` -- save the distances to a file
|
||||
(loading which might be faster than recomputing)
|
||||
|
||||
* `-sag_gdist_load filename` -- load the distances from a file
|
||||
|
||||
Graph
|
||||
-----
|
||||
|
||||
Just use `-sag-weighted` to read a weighted graph (in format `node1;node2;weight`),
|
||||
or `-sag-unweighted` to read an unweighted graph (in format `node1 node2`).
|
||||
Just use `-sag-weighted` to read a weighted graph (in format `node1;node2;weight`), or `-sag-unweighted` to read an unweighted graph (in format `node1 node2`).
|
||||
|
||||
You can also use `-sag-edgepower a b` to use pow(w, a) * b instead of weight w listed in the file (enter this before -sag-weighted).
|
||||
|
||||
See the cpp files for other options available.
