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.

Ask HN: Any good books on ray tracing?
Physically Based Rendering[0] was an excellent textbook when I read it ages ago and conveniently enough it looks to have been updated with a new edition last year.

C++ Project to Put On Resume
Both of these books are free, and both are written in C++, but they can be done in any language. The first book, a raytracer in a weekend, is part of a series, you can find it here: https://raytracing.github.io/ And, if you get to the third book in that series, or you need a reference book, the PBRT book covers the math in more depth and discusses the latest theory, you can get the last edition of the book (5 years out of date) for free though: https://pbrt.org/

(Why) is a toy password manager a too complex summer project?
Making a “complete” one is a never-ending rabbit hole you can spend a lifetime on and is a very active area of research covering more advanced geometry, probability, optics, machine learning etc etc. A great introduction to that is https://pbrt.org

Suggestions for some best books on computer vision
This isn't the highest priority but if you haven't already, learn how computer graphics works. Get a working knowledge of the camera matrix, real time graphics (say, OpenGL but threeJS is an option), and photorealistic graphics. PBRT is the go-to for photorealistic graphics. The first two books of Foundations of Game Engine Development are way more useful than they have any right to be (and my favorite textbooks I've ever read, 10/10).

Org Mode Gripes
Org-mode strength though is in working with different languages in a same source file, which I am not sure if Knuths version does. Anyway, to see how the original idea looks like, check the Wikipedia article, or to see it in real-life see some of books that are written in the literate style, like Physically Based Rendering, which seems to be available for free nowadays or C Interfaces and Implementations.

Physically Based: A Database of PBR Values for Real-World Materials
I contributed a tiny bit to pbrt[1], and one of the things I loved was that if you just plugged in physical values you almost always got great results with minimal tweaking.
The Octane data seems most complete at first glance (with complex IOR etc), but for things like milk and blood I expected at the very least some absorption coefficient for the translucency or similar.

Raymarching Distance Fields (2008-2020 compilation)
Raymarching stuff looks incredible in VR but most of the available examples are web-based and the overhead of WebGL for a technique that relies on raw GPU throughput often kills it.
Someone really needs to update this to work with current headsets and controllers: https://github.com/jimbo00000/RiftRay
(it works on the Rift last time I checked but uses the original 3DOF remove for interactions)
