OpenSCAD... quite a bit faster
Here's an article describing some awesome work currently
going on:
"OpenSCAD 3D rendering just got an order of magnitude
faster. Here's how and what may come next."
https://ochafik.com/jekyll/update/2022/02/09/openscad-fast-csg-contibution.html
The main change is already available in the development
snapshots. The extended options mentioned in the article
will become available with the next builds in a couple
of hours. Check Preferences->Features for "fast-csg".
Big thanks to Olivier!
ciao,
Torsten.
People may also want to cast an eye on memory usage if trying fast-csg.

Unfortunately it doesn't run on Win7, so I can't try it.

It does run on my Ubuntu 21.10.

I cast an eye on my memory usage. used: 10%, free 77% (about 12% is
cache). And?
From the explanation, I don't think there would be a bigger memory
footprint. But the performance improvement is certainly noticable. The
example 100 spheres with $fn=50 renders in 2.7 seconds as opposed to 4
minutes on my system.

f equals m times a. When your f is steady, and your m is going down
your a is going up. -- Chris Hadfield about flying up the space shuttle.
I am currently working on a cast bronze plaque. One half with 24 letters, the other with a motif.
Normal preview time ~ 1 min, render time ~11 min.
With fast-csg(-exact(-callbacks)) preview time ~ 1 min, render time ~1 min !!!!.
Memory usage appears to be unchanged.

Great news. I have lots of projects where I gave up on OpenSCAD because it
was just too slow (or even never completed, even on a machine with 256GB of
RAM and OpenSCAD settings to use it...).

Should the GUI be restarted after changing features?
Different data structures?
And should Help/Library-Info show which features are enabled?

No, I don't think that's needed. Although cleaning out
the cache might be a good idea.

It does, but it looks like it's only done once when
the dialog is opened first. So it would need to be
changed to refresh when the dialog is shown.

Have there been fast-csg changes to master since the Snap openscad-nightly, still dated 13 Feb
2022? https://snapcraft.io/openscad-nightly

Yes, there's at least one bigger fix for an issue that could cause
missing parts.
If you want to make sure to always have the latest build, you can
use the "edge" channel. This one is built automatically.
The normal release channel, I'm updating manually from time to time.
(Updated just now)
ciao,
Torsten.
