Please note that support for Node.js 12 will be removed soon. Node.js 14, 16 and 18 are the maintained versions.

@Antoine-Guillaume thanks for joining!

You won't be able to precisely mimic the bending of steel plates. Maybe

You can use offset to create a round bend. First, create a path for the L, then offset the path to create rounded corners. And finally, extrude linearly to create the plate.

Please experiment. I think that you can find an answer.

There are other ways as well, so let us know if you need more help.

By the way, we have many members so please us you favorite language.

@Hermann-SW Thanks for all the super insights to your designs. It has been great to see you continue and improve the designs, and finally have a great base for more designs.

I haven't seen anyone compare JSCAD to OpenSCAD viewers. We continue to improve the viewer (and modeling library) so it's really nice to have some complements.

We have had some recent performance improvements, based on @platypii and @briansturgill changes. And we have more planned ahead.

z3dev

@cncandi It looks like you made a copy of the JSCAD website. That's really customize to support drag-n-drop, loading projects, URL options, etc. It's probably not what you really want.

Take a look at the websites and frameworks mentioned here.

https://openjscad.xyz/dokuwiki/doku.php?id=en:user_guide_help

Let us know if you have any more questions.

z3dev

@Hermann-SW There several examples of websites mentioned in this user group, so you might want to contact those authors.

It seems that you already stumbled across the simple demo as part of regl-renderer. You could build upon that, or adopt one the frameworks, such as React.

You can find some links on the User Guide. I'm trying to keep this up to date.

There's a new release of JSCAD, including changes from several pull requests.

Welcome TAU!

TAU is the true constant for relating the circumference of a circle to its linear dimension.
Equivalent to PI*2. You will now find TAU throughout the code base, and mentioned in documentation.
We believe TAU will make rotations simple to understand.

EXAMPLE

const { TAU } = require('@jscad/modeling').maths.constants
const { cube } = require('@jscad/modeling').primitives
const { rotate } = require('@jscad/modeling').transforms

const main = () => {
  const shape = rotate([TAU/4, TAU*0.75, TAU/24], cube({}))
  return shape
}

module.exports = {
  main
}

For even more information about TAU, see The Tau Manifesto

Features

modeling: added TAU constant to maths, and refactored code and documentation
web: added chinese translations to desktop/locales and web/locales

Bug Fixes

modeling: added TS definitions for modifiers

Thanks to @jobinson99 for the Chinese translations for the website.

@Hermann-SW Good questions...

The website has a little Perl script that does the download of the requested file, and checks the content. This does two things; only know file types are allowed, and this goes around CORS.

https://github.com/jscad/OpenJSCAD.org/blob/master/packages/web/remote.pl

I guess that supporting data URL would be possible, but there would have to be some similar checks for data type, etc.

z3dev

@Hermann-SW thanks for the suggestions.

The support of data URL contents is not trivia, especially if you expect the 'data' to be evaluated as a JavaScript module. That's kind of breaking every security rule in the book.

However, the support for DATA formats might be possible, such as supplying JSON contents. But that would be very limited.

I think the real solution would be allowing the require() to include modules from remote sites. There are many such requests (issues) for the same functionality.

If you have any ideas then let's discuss via the GitHub discussions. There may be a solution, as modern browsers have a lot of functionality.

z3dev

@Hermann-SW I'm not surprised. The boolean functions require memory and CPU, so high resolution spheres will be very slow. However, newer computers are extremely fast now, so please keep making cool designs!

z3dev

@Hermann-SW WOW! Very nice!

I'm very impressed with the speed of the algorithms! I was expecting to wait for minutes before viewing. But the design was viewable almost immediately!

Do you think that any 3D shape can be 'fitted' to a sphere? How about to a cylinder?

z3dev

@David-Bolt The latest release has a change which retains the webworker thread. So, debugging should be easier now.

@Ion-0 it was great to meet up. I'm totally impressed with the amount of effort and engineering that went into the web application. Really cool stuff!

Let us know how JSCD needs to improve to assist others.

Makers Faire Tokyo

JSCAD has been accepted as a participant to Makers Faire Tokyo 2022. Makers Faire is very exciting exhibition, full of crazy and innovative ideas from a vast array of people.

If you get a chance to attend (the YEN is really cheap now) then let us know. We have a ticket for you!

z3dev

@ion-0 thanks for the nice offer.

You can contact me at z3-dev at gfnews dot net

Hopefully, we can meet online and discuss. A demo with some explanations would be a lot of fun.

z3dev

@david-bolt good question!

It may require changes to the regl-render. You can probably start there, and see if there's support. I would guess that the initial view can be changed for the demo.html

z3dev

@ion-0 that's WAY COOL!!!!

Thanks for sharing!

FYI, we (JSCAD) will be presenting at 2022 Tokyo Makers Faire. Do you mind if I show the site off?
