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.

What can you make with C++?
This is the library: https://github.com/jbuckmccready/CavalierContours

Need help to understand c++ library
Yeah, thats about the things that i cant learn quickly by myself. Anyway, is there any case that the library author put up header in .cpp rather than .h? In this https://github.com/jbuckmccready/CavalierContours

New 2D computational geometry library
Sometimes they are called "polylines (or polygons) with bulges" e.g. in AutoCAD. See also https://github.com/jbuckmccready/CavalierContours for a desription and an offset algorithm implemented in C++ and Qt.

Is there a quadtree implementation with generic types for the coordinates?
Depending on your use case this crate provides a very fast static (must be rebuilt to add/remove bounding boxes) axis aligned bounding box index: https://github.com/jbuckmccready/static_aabb2d_index. It's very fast to build the index using hilbert curve sorting and forms the index structure as a tree with controllable node sizes.
