manifold VS kons-9

Small in a relative sense compared to some larger codebase.

Here's a bit on Manifold:

https://github.com/elalish/manifold/wiki/Manifold-Library

and the author's blog is interesting:

For cad kernels I highly recommend manifold https://github.com/elalish/manifold

Our project https://github.com/elalish/manifold made use of this to speed up mesh processing algorithms a lot.

Wondering why no BRep support means it is not a CAD. It seems that OpenVSP doesn't use BRep but uses parametric surface [1]. I wonder if mesh-based modeling + some constraints solving will get you a CAD, or are there other requirements that I don't know? I only work on mesh processing library on my free-time and I don't know much about BRep.

Unhealthy relationship with keyboards? Comparing with the r/MechanicalKeyboards or r/ErgoMechKeyboards people this relationship is more like divorced...

I added python binding and ended up being on of the devs for https://github.com/elalish/manifold because OpenSCAD is too slow for my modeling (I am quite impatient). Optimizing my keyboard for months with more than 5 complete rebuilds to optimize my design (looks like this: https://i.redd.it/xtf0f54mt7ya1.jpg), and is afraid of open sourcing it because my code looks too bad :(

Now much faster and more stable thanks to the Manifold engine (https://github.com/elalish/manifold): in fact it is often faster than the last stable desktop release from https://openscad.org/.

Also much better code completion, and ships with a few examples from the various bundled libraries to get you started.

At the end, they gonna replace it with ( elalish manifold.

Very cool. I must check this out.

I implemented some L-system features in my 3D Common Lisp system: https://github.com/kaveh808/kons-9

In some small way I am revisiting the idea with https://github.com/kaveh808/kons-9

We'll see what comes of it.

I began my 3D graphics development on a Symbolics workstation at the MIT Media Lab in the mid-80's. This was before the S-Graphics suite was released. [0]

The outstanding feature of the S-Graphics suite was the polygonal modeler which used a winged-edge structure that was far ahead of its time. It survives conceptually in the Wings3D system, which is a quite faithful copy of that modeler.

And of course you got the extensibility that came with the graphics system being built on Lisp.

But Symbolics was never, as far as I saw, a serious or popular contender in 3D production. Not only was the system expensive, but the hardware could not keep up with SGI's graphics abilities. Furthermore, the mass of CG developers at the time came from a C/Unix background, and rendering especially was so speed critical that C (and Fortran) resulted in faster systems.

Almost 40 years later, I have returned to the idea of developing a 3D system in Common Lisp [1]. We shall see where it leads.

If you are interested in 3D graphics, I have tried to keep my code simple and comprehensible: https://github.com/kaveh808/kons-9

As a solo developer of my 3D system, my main focus has been to keep the enthusiasm and momentum going and to enjoy the development process, rather than worrying about how the code might not be optimal in various regards.
