Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Kings Park Psychiatric Center – one last masterpiece
I forgot to add, at the time in 2014 I was working on this project
https://news.ycombinator.com/item?id=32491982
which lead to this one:
https://github.com/JMC-design/tovero
As I was taking a break from writing that "wall of text" last night, I finished my "Homer's Donut" shape, a 3D torus with a 0 - 360 degree arc to connect pipe-like shapes. My pipe-routing code is almost finished as of this morning.
My parents also taught me to "pick myself up, dust myself off, and start all over again." Peter Tosh too. So I guess another trite quote, "It's hard to innovate when you keep receiving 'being hit over the head' lessons."

> It looks like your e-mail was the victim of my paternity leave
10 years is generous paternity leave. :) Seriously though, no hard feelings, separating the wheat from the free software chaff takes time--ask me how I know.
> interactive editor like mged with lisp wrapping BRL-CAD's libged editing library
That interests me!
IME, I have found S-expressions to be an elegant, succinct way of expressing geometric models (especially in the F-rep domain):
https://github.com/JMC-design/tovero/blob/master/examples/ro...
I wrote a referencing counting C++ reader/writer for S-expression models like that directly into Open Inventor, in place of the IV (VRML) format, avoiding the use of CL.
Emacs has a C FFI, IIRC, so it should be possible to develop a S-exp formatted BRL-CAD model in elisp, with the right C shims--giving a live-coding, REPL experience for building BRL-CAD models.
Thanks for your work on BRL-CAD!

New open source Common Lisp 3D graphics project -- call for participation
I am in very early stages of writing a graphics engine in Lisp that uses SDFs, but the progress is slow (lack of experience, plus need to focus more on a new job and less on hobby projects). If you are also interested, here'a a repo full of all kinds of research work to implement a SDF based engine.
What are some alternatives?
wgpu-native - Native WebGPU implementation based on wgpu-core
cl-vulkan - Vulkan bindings for Common Lisp.
curated-code-cad - A list of the various code-cad projects out there.
vk - Common Lisp/CFFI bindings for the Vulkan API.
kons-9 - Common Lisp 3D Graphics Project
xi-editor - A modern editor with a backend written in Rust.
libfive - Infrastructure for solid modeling
