fast-csg no longer an option in OpenSCAD development snapshots

[hairyhenderson]

I've just been trying to render the rugged gridfinity box after some months away, and upgrade my OpenSCAD dev snapshot in the process.

Unfortunately, it looks like fast-csg isn't available anymore, since openscad/openscad#5343. And the model renders extremely slowly for me now.

Perhaps the instructions should be updated?

I installed the development snapshot using flatpack and fast-csg option is still there. The version I am using is: OpenSCAD version 2024.06.13

What version are you using?

[hairyhenderson]

@jokober the version you're using is from June, the referenced feature was removed in September. I was using a development snapshot (downloaded, not installed with flatpack)

Does Backend Manifold solve this?

Using latest development version with Manifold backend results in slow rendering it seems.

Not sure what to expect on a Mac M1

[hairyhenderson]

@pietgk yes, it does - at least in the nightly version 2024.11.10

Ok, Thx, I'm using 2024.12.01 so i assume the time it takes to render is what it is.

Or do we want to ask for fast-gci to be enabled again?

What is the nicest way to get README.md updated?
