@sopatt Sorry to the late reply.

You probably already know this but an ''orientation" is required to determine the rotation, and sign of the angle.

This is probably the best implementation out there. And if you want then this could be added to the vec3 functions.

@Christopher-Fry OH! A V3 user! Awesome!

The modeling library is getting there, and pretty mulch complete, functional, and tested. We expect a few bugs, and a few more API improvements. But nothing radical.

Also. we are setting up a new website which will have a landing page, both V2 and V3 web UI applications, and more.

There's no plan yet for the BIG switch to V3. So, expect a few more V3 beta versions.

@BOYUAN-SHI Welcome

I have done some designs using my iPad, which was a little cramped for viewing. Technically, everything worked fine.

If you are working with a project with multiple files then probably a PC would be better. You can drag and drop the whole folder to the website. And change any file.

I think most people use a favorite editor to make changes, and drag and drop the file to the website. That works really well.

@sopatt @sopatt That's cool stuff. In the early versions there was a 'connector' concept but that was left behind. We really want to bring that back in V3, so I'm wondering if your efforts could contribute to a better version.

z3dev

@patilanz Welcome,

Sorry, I didn't see this before.

DXF web editor. DXF is just a file format created by Autocad long long ago. There are many online websites that can read as well as create DXF files, including JSCAD.

Does that help?

z3dev

The booleans are working fine but the orientation of the polygons are super important. You can check the orientation your self, but one of the easiest checks if volume().

Hope that helps

z3dev

@sopatt Welcome

You don't have to worry about applying the transforms. That's done automatically before other operations like booleans, etc

You just have to position the shapes properly.

If you provide an example then we can help out. Also see some of the more complex examples.

z3dev

@Mayank-Dogra Welcome!

There's a really simple demo in the regl-render folder. Take a look at that for an example.

@sopatt Thanks for the feedback.

FYI, Most computations are based upon the glMatrix library (glmatrix.net)

I will double check but this is probably the same functionality as glmatrix.

Here's my first fractal.

z3dev

There are a couple of JSCAD add-on packages available from NPM now.

https://www.npmjs.com/package/jscad-text

https://www.npmjs.com/package/jscad-object-api

z3dev

@hpb-htw Super! You understand well.

Each package will have a slightly different version, as Lerna determines major/minor/fix versions by changes. The main package is never released so, the version stays the same, but should be 3.0.0.

Please take another look at utils/regl-renderer package. The demo html files are slightly different in V3.

z3dev

@hpb-htw V2 uses Lerna to manage each package, including building and publishing the distributions to NPM. See the link in the main README.

As part of the build process. Lerna calls the build step of each package. This step uses browserify.

If you switch to the V3 branch then you will find that The build step is using rollup.

So, be careful. Don't mix the versions.

By the way, the CONTRIBUTING document explains how to setup, make changes, test changes, and submit changes back to GIT. Please follow the document.
