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.

Is there a common method to do glossy reflections in Vulkan ray tracing?
I found a great PRNG in a shader https://github.com/nvpro-samples/vk_mini_path_tracer/blob/main/vk_mini_path_tracer/shaders/raytrace.comp.glsl

I’m am an beginner when it comes to openGL, and am thinking about implementation of ray tracing in my engine, and came across compute and mesh shaders. I have a few questions regarding them, so could someone please help me with these?
NVIDIA has a couple of options for you to start learning hardware ray tracing. This requires you to use either Vulkan or Direct 3D 12, of which both are modern (i.e. low low level) APIs. In my view, you would be well-advised to budget significant amounts of time just to re-learn the traditional rasterization pipeline in Vulkan before thinking about raytracing. It took me quite a while to get up to speed on command buffers and synchronization and all the other ilk that OpenGL (mostly) doesn't ever expose. That said my colleague Neil Bickford has put together a tutorial for Vulkan raytrace extensions that does not assume prior Vulkan experience: https://github.com/nvpro-samples/vk_mini_path_tracer
