Vello, https://github.com/linebender/vello.
Vello is a 2D graphics rendering engine written in Rust, with a focus on GPU compute. It can draw large 2D scenes with interactive or near-interactive performance, using wgpu for GPU access.
The more I learn about Vello, the more I'm fascinating by the number of state-of-the-art techniques that are used. It's so rich.
e.g. Fast GPU bounding boxes on tree-structured scenes, https://arxiv.org/abs/2205.11659
