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.

I just released 3D Perlin Noise Marching cubes generator
I still haven't uploaded it to the marketplace but I will soon. Anyway here is the repo - https://github.com/mikhomak/Ue4MarchingCubes

Is PerlinNoise overloaded to make procedural maps?
Note the notice at the top of the readme, the author is replacing that library with FastNoise2 which is also SIMD enabled, although the library as a whole is still a work in progress, it claims to have superior performance.

Starting of a voxel terrain engine
I am using a very fast [noise library](https://github.com/Auburn/FastNoise2). After generating a 64x64 area of noise I turn that into a 64x64x64 array of voxel byte data. I then use my own version of this [greedy meshing algorithm](https://github.com/cgerikj/binary-greedy-meshing).

How do space games handle the scale without loading screens?
There's a nice GDC talk about noise functions here, and if you're interested in trying things out there's an Open Source noise library written by a No Man's Sky developer here.

UltraNoise - An OpenSource Node based processing tool for Unity (link in comments)
Very cool! Have you considered using FastNoise2 as a noise source? It's SIMD optimized C++ https://github.com/Auburn/FastNoise2 But they've made C# bindings so there's less native legwork: https://github.com/Auburn/FastNoise2Bindings

Cricket, a coherent noise generation and manipulation library
Let Simplex 3D use its same gradient generator, but use 1/2 instead of 1/6 for the noise's unskew constant. This rotates the axis angles of the gradient set out of the main noise evaluation planes. I haven't implemented+run this myself, but it is implemented here in FastNoise2 (SIMD library), and I simulated the difference using OpenSimplex2 in this image (bottom with change). The result isn't perfect, but it's much nicer I think. After making this change, either set scale to 32.69428253173828125 to make a proper -1 to 1 range, or bake it into the gradient table directly.
