Thanks for the link. But I don't understand how to put this in practice. I
mean, as far as I understand, you're suggesting to run r.spread in a loop,
each step producing a final map as image and then compose together as a
video, right? I had also thought something of the kind, but I was looking
for a way to save the detailed fire evolution as it is generated by
r.spread, hence a way to redirect the output directly to a video, or at
least save several static images while r.spread is running, and then to
compose them as a movie. Is that feasible?
