The distraction rabbit hole

things I am working on (shameless plug)

• Multipart project template others could find useful #1141 - multi-part project template
• WEB Prototype #944 - a long running process of making a new version of jscad web that I would be able to help maintain.
• instancing performance to display large number of shapes that are same geometry but transformed.
• procedural screw example of performance benefits to procedurally generate common stuff aside from primitives (created some time ago, not yet integrated to jscad, likely will be a node module)
• screw dimensions lib - providing a common database that can be utilized by many different CAD applications. Hopefully I can make a superfast generator for these based on link above.

BOOLEANS

Other engines that do booleans

Manifold (WASM)

A new boolean library that creates manifold shapes(no more errors in slicer) claims up-to 1000x performance gain over csg.js/(that is used by jscad). It is very promising and might be good to consider to offer as an option to use with jscad modeling. A quick test of cutting a sphere(256 segments) from a cube gives 35 sec in jscad, versus 0.07s in manifold. And jscad produces non-manifold 3mf.

Walnut (WASM)

An ineresting different approach to 3d booleans.

CGAL (not JS, no WASM)

booelans and everytinhg else and if u are like me, could be you are not even aware of it.

OpenSCAD

The inspiration that for the jscad, in the old days when WASM was not yet a thing

• https://github.com/DSchroer/openscad-wasm - WASM build
• https://openscad.cloud/ - online editor based on the WASM

OCCT - OpenCascade

This one is different in that it uses BREP to describe geometry, but is used very much in desktop apps like FreeCAD.

• https://github.com/donalffons/opencascade.js - is WASM build of it
• https://zalo.github.io/CascadeStudio/ is one attempt in providing api
• https://replicad.xyz/ is another API on top of the WASM by author that did not like CascadeStudio API

..........

it will take some time to put massive number of links I hoarded, so I will update this list slowly.
