Generic e-paper (e-ink) panel driver for ESP-IDF, exposed through the standard esp_lcd panel interface. Adding a display is one descriptor, adding a controller family is one file. Ships SSD1680 support and the 2.9" GDEY029T94 panel, with full and fast partial refresh.
A self-contained 3D renderer for embedded targets: a binary asset container, skeletal animation, tile binning, a software rasterizer and a 2D canvas. Header-only, with no third-party dependency of any kind.
