Hello, I'm still working on slicing scripts, and as functions like projection and lieFlat won't be part of v2, I decided to write a simplier one. My idea was to get a 2d slice of a 3d volume by intersecting it with a volume having a flat top, then only keep the resulting polygons having all vertices with Z corresponding to the flat top Z coordinate. It seems to work fine. My aim is to teach basics of OpenJSCAD to non programmers crafters, so I'm looking for easy code.

The following snapshot shows a tiny jscad allowing to retrieve a cylindrical slice from a volume.

I'm using development web console to have output, that would be great to be able to have output parameters for that, but I understand that is not something critical, it can be handled using the console output.

@kaosat-dev At first I tried to use a 10K triangles model but as it didn't render I downscaled to 5K, 3K, 2K then 1K. And after, I made another model with 2x more slices that this script was unable to render even with a 1K model, so I changed the script to make it render chunks of slices, and it was ok. I suppose it could work with higher resolutions models.

Hello,
With the same script and 3d model, I made a 60 cm tall statue with 200 sheets.

finished

@z3dev I'm making the statue

Hello, I'm using OpenJSCAD to slice a model to laser cut it and it works fine on a model with 1000 triangles. I use the SVG export directly and that's very nice, even if there's little editing to do before to export to gcode and cut.

@wolfgangfahl To make it work without having to move examples folder, you can run it from your local webserver. I did so from my local apache http server

@wolfgangfahl if you copy examples folder into web, it will work

Hello, did you try with viewer-minimal.html that is into packages/web directory ? It seems that the code you used for your demo is very old. There are minimal examples for years now.
