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.

Pico3D: Open World 3D Game Engine for the PicoSystem (RP2040 Microcontroller)
Very impressive, and very fun :)
I wish I had the time to do this, but it looks like it would be relatively simple to modify render_rasterize.cpp [0] to do perspective-correct texture mapping [1]. I also wonder if going for a scanline approach [2] would be faster than iterating over the whole screen calculating barycentric coordinates?

Pico3D: Open World 3D Game on an RP2040 (PicoSystem)
I have worked on an open world 3D game running on the Pimoroni PicoSystem for the past few months to proof it was possible :). Gameplay video: https://m.youtube.com/watch?v=n6bECGQyNuk Source: https://github.com/bernhardstrobl/Pico3D

Using external sram?
You can use one of the many SPI/QSPI PSRAM chips that are available. If you don't need to have it have it mapped as actual memory that you can malloc, using it should be pretty straightforward. I've written a library to help interface with SPI PSRAM over PIO & DMA, and I've tested it at up to 140MHz (with the RP2040 running at 280MHz): https://github.com/polpo/rp2040-psram
