High performance graphics and text rendering on the GPU for...
summary
A small open source library called CS paint sits on top of Vulkan and collapses the roughly 700 lines of Vulkan setup into a few C++ calls, letting a C++17 demo render a 3D scene (the pot mesh is about 10,000 triangles) and crisp GPU-rendered text using a multi-channel signed distance field glyph texture. The demo uses 48×48 glyph tiles, currently covers Latin‑1, shows sharp scaling at extreme zoom, and the library works — code and shader examples are included.
