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.

SDF Viewer: a fast and cross-platform Signed Distance Function (SDF) viewer, easily integrated with your SDF library
Afterward, this GLSL shader does the actual rendering. This shader is applied to a cuboid mesh that represents the bounding box of the object. The mesh is useful for only raytracing the part of the screen that may reach the object, and for extracting the rays for each pixel from the hit points. The shader simply walks along the ray for each pixel, moving by the amount of distance reported by the SDF on each position. If the surface is reached at some point, the normal is computed and the lighting is applied for the material saved in the closest voxel. To get the distance at a point that does not match the grid, interpolation is applied, leading to round corners if the level of detail is not high enough.

The Orb: a parametric trackball with BTU mounted ball and keyboard switches for buttons
curv seems to have cad/slicer integration in mind as a long term goal, using f-rep to generate infill as well as the shape itself.
