vis
usage: vis [-threads #] [-level 0-4] [fast] [-v] bspfile
fast
This will only calculate a very loose visibility list. It doesn't take much time
to calculate, but a lot more polygons will be drawn by the Q3 engine than
necessary.
hint
Enabling this switch enables -merge, but will not merge hint portals.
merge
This merges bsp leaves before calculating the visibility list. This will speed
up the vis calculations, but a lot more polygons will be drawn by the Q3 engine
than necessary.
nopassage
This will disable the passage visibility algorithm. The passage vis is faster
and a bit more tight than the old algorithm.
nosort
This disables the sorting of portals by complexity. Generally, sorting will
speed up visibility calculations, because portals that are more complex can use
information from less complex portals.
passageonly
WARNING: Unknown option “-passageonly”
saveprt
This disables automatic deletion of the .prt file after creating the visibility
list.
tmpin (path)
The input files will be read from a folder called tmp.
tmpout (path)
The output files will be written to a folder called tmp.
These need further work/clarification
