Here's something for those wanting 'more' from JSCAD designs.

The 'fs' (File System) module is available to designs, both NODE.js and WEB versions.

const fs = require('fs')

The WEB versions is not 100% compatible, but it can provide access to other data. For example, fonts can be added to the contents of a JSCAD project. And the font can be read via the 'fs' module.

const data = fs.readFileSync('project_text/Osaka.ttf')

And used with the jscad-text project, outlines of characters can be created very easily.

const {primitives} = require('@jscad/modeling')

const { loadFontFromData, textToPaths } = require('./jscad-text')

const fs = require('fs')

const main = (params) => {
  const data = fs.readFileSync('project_text/Osaka.ttf')

  const font = loadFontFromData(data)

  const paths = textToPaths({font, segments: 144}, 'JSCAD!　大好きです!')

  return paths
}

module.exports = { main }

Release : 2022 JUN 12

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

Features

x3d-serializer: enhanced to convert 2D geometry and path to X3D Polyline2D

Bug Fixes

examples: create uniform segments for involute gear example
modeling: use special trig functions for rotations in maths and primitives

Performance Improvements

modeling: optimize poly3.measureBoundingSphere and cache results for performance
modeling: replace Math.hypot with faster Math.sqrt()

Thanks to @briansturgill for providing performance hints in the BSP trees.
Those hints have resulted in 40 to 50% boosts in performance.

Also, improved TypeScript definitions for all geometries.

BIG NOTE: The V2 website is also using this release.

There's on-line documentation as well for those needing additional information about the modeling API.

For those using a local copy of JSCAD V2, be sure to run the following commands.

git pull
npm run clean (and answer Y)
npm run bootstrap

Both CLI and WEB UI are usable for creating designs. In the WEB UI, it's best to drag-n-drop project folders to the window, and work with the pieces via a favorite editor. If "Enable auto reload" is checked then changes will be detected, and rendered again.

For those wanting to get hold of JSCAD V2, it's still in 'early adoption' mode. But you can get started here.

And a BIG THANKS for everyone that has provided feedback. Keep those comments coming!

We had a great time showing JSCAD at Maker Faire, showing both V1 and V2 (alpha alpha) to folks, as well as entertaining kids with a small toy designed with JSCAD. As usual, the faire was packed both Saturday and Sunday.

@hrgdavor thanks for the prerelease event.

There’s one more special function coming; scission()

This one is totally inspired by @gilboonet

FYI, this is tied to a MAJOR RELEASE of the modeling library, so please pay close attention to the release notes.

I’m hoping to show JSCAD again this year. Let me know if you’re in town.

z3dev

@BarbourSmith Thanks.

I noticed that as well. For now, you'll have to manually switch the version to 'alpha'.

z3dev

@udif great question!

There are three main objects; geom3, geom2, and path2. You can create empty versions of these…

const a = geom3.create()
const b = geom2.create()
const c = path2.create()

z3dev

@kevinos welcome!

The JSCAD model (code) is required as the compilation is completed by the browser. So, you will have to find ways to obfuscate the code.

z3dev

It’s been a while since we have posted any update on V2, so here’s a few notes on what’s going on.

First, the reorganization of the CSG library is almost done, but like always the last 5% takes the most time. Once again, the major goals are:

Move to functional API, i.e. no more monolithic objects
Standardized function names, parameters, error checks, etc.
Lots of small modules to allow more reuse
Math and Geometry data structures based on arrays
Tests for everything

There have been some name changes to functions, but the new names are clear. Parameter names haven’t changed much, but one major change is the usage of RADIANS for all angles and rotations. There are several bug fixes and improvements as well. Tests… yeah… lots… 394 test suites with over 90% coverage.. and this will continue to improve.

Second, all JSCAD libraries are being brought together into one repository; OpenJSCAD.org. This allows the libraries to be managed together, and produce releases faster. And hopefully, contributions from anyone at any level will be easier. This includes the CSG library, IO library, and new viewer.

Third, you can start following along. There are still a few major changes coming, but you can already get a good feel for things by cloning the OpenJSCAD.org repository, and looking at the V2 branch.

Feel free to ask any questions about V2.

z3dev

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

Fixes:
modeling: correced snapPolygons to remove duplicate vertices which is possible (#791) (1eaf86f)
regl-renderer: corrected zoomToFit for 2D geometries (#793) (2a05d3e)

@kevinos no problem.

so, JSCAD designs are actually Javascript functions which perform calcuations, create geometry, perform operations with geometry, and finally return the geometry of interest.

const {primitives} = require('@jscad/modeling')

const main = () => {
  let object1 = primitives.circle({radius: 22, segments: 36})
  object1.color = [1,0,0,1]

  return object1
}
module.exports = {main}

The return of object1 from main() is a 2D geometry, i.e. a geom2 object. In the WEB UI, this object is passed to the 'rendering' function, and shows up on the screen as a red circle.

The Vue component requires 2D/3D geometries as well. And as a Vue component, it can live inside another Vue component (or application). This is the rendering piece only.

The JSCAD WEB UI is doing a whole lot more underneath. It loads all the code, evaluates (compiles?) each piece of code, and finally executes the main() function.

If you want this functionality then there's some more plumbing required.

z3dev

There's some new functionality coming with V2, which is pretty exciting. So, I thought a little preview would be nice.

This is the new offset() function, which can calculate the offset of a path or a 2D geometry.

Here's a photo of a line (black) being offset both positive (green) and negative (red), with rounded corners.

And here's a simular image of a 2D geometry, but note that this geometry has a hole. So, offsets are applied to both inside and outside edges. In this case, the corners are only connected at the intersection of the edges.

Hope you like this one!

z3dev

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

Bug Fixes

examples: corrected sphere, text, balloon examples, added orientation example (#840)
regl-renderer: added reasonable defaults for drawGrid
regl-renderer: corrected conversion of empty solids to entities, updated tests
regl-renderer: corrected determination of camera position change in orbitControls
web: another attempt to fix performance / elasticity issues of viewer
web: replaced JSON comparisons with ID comparisons in viewer

FYI, the most-gestures package has been integrated into the web package.
