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!

@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.

@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

@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?

@david-bolt nice to see another design.

I will double check but I don't think that Orthographic view has been enabled.

@steve-howe Sorry. A project can be loaded via the LOAD button, or drag-n-drop. The best is via drag and drop due to differences in browser functionality.

@steve-howe there's a small section about projects in the User Guide. This might help.

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.

Hopefully everyone is watching the progress of JSCAD. It continues to build popularity, and now has 2000 stars. Please visit the JSCAD project at GitHub.

Here's some inspiration for those wanting to build something cool. @frading has created a completely new WEB UI for creating interactive designs, called polygonjs

@gilboonet let us know if you think any of the designs seem 'incorrect'. I'd be glad to help out. And of course, fix any bugs.

@gilboonet super! Please let us know how the catalogs are published. I'm sure many will want to do the same.

OBJ... it's a good format for exchanging designs, but not very popular. I think most users will want to download STL.

@ajw1970 super!

I'm interested in the final application. Why did you want to use Babylon for rendering? And do you further plans to create some online designs?

Release : 2022 MAY 15

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

Bug Fixes

• core: catch and create create message from thrown objects (non-Error)
• core: corrected webRequire to catch errors from dynamic code evaluation, and rethrow with correct context
• web: corrected messages from parameter runtime errors (missing types, etc)
• web: corrected status (error) message format and display
• web: enhanced design state management to handle error messages

Features

• core: corrected rebuildGeometry to catch all errors, and callback with complete error information
• examples: new Nuts and Bolts example
• regl-renderer: added support for multicolor lines

Performance Improvements

• maths: reworked mat4 isMirror to use pure math, eliminating vec3 creation
• modeling: improved performance of reTesselateCoplanarPolygons by using maps or sets
• modeling: use Map instead of {} for slice.repair

Please note the major changes to the core package, as this may break some custom web pages.

@antoine-guillaume welcome

You will have to assemble the special shape from lines and arcs. You can look at the code for rounded rectangle for some inspiration.

https://github.com/jscad/OpenJSCAD.org/blob/master/packages/modeling/src/primitives/roundedRectangle.js

Release : 2022 APR 24

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

Bug Fixes

• modeling: corrected torus manifolds
• modeling: removed path2.eachPoint which was broken and unused
• modeling: reworked project to correct union of small polygons
• regl-render: removed unnecessary preventDefault in demo.html
• web: remove unused file handling and storage path options

Performance Improvements

• modeling: changed internals to use geom3.create(), path2.create(), poly3.create()
• modeling: faster geom2.toOutlines
• modeling: performance improvements to mergePolygons and triangulatePolygons

There have also been some style changes to the website, so please let us know if anything looks strange.

@rozek thanks for the insights.

I think most of your suggestions are spot on. The logic of vectorChar and vectorText are solid but these data structures don’t produce anything that can be immediately used.

I’m not certain which direction will be taken, so I created a new issue to track these ideas, #1067

@jin-kim Welcome!

I don't know of anyone porting the JSCAD modeling library to Java, but it should be possible.

A few years back, someone ported V1 to C++ but I don't have the link.

And very recently, someone has ported the JSCAD modeling library to C# , and there will be an announcement shortly.
