Based on mesh2.
Now to build a train. Perhaps actual trains should go on a less bumpy
surface, but this one tests the code...

I won't board a train on that route...
When building railway tracks the irregularities in the surface are usually
strongly compensated, it would be interesting to automatically modify the
terrain according to this (i.e. cut in or build tunnels at the hills and
add material/build bridges in the lower parts)

Yes, I was already thinking along this route.
Q: what's the fastest way to do so? I suppose CSG with an iso will choke
pov.

The engineers would first optimize the route to use the flattest terrain,
then they would cut and fill, tunnel and bridge as much as was required to
keep the tracks below a given grade and curvature.

Agreed, but it would be a perfect start for an animation with a cartoonish
train, I imagine.

Highest compliment a two year old can pay his father (and mother):
