Direct2D GPU PDF renderer with CPU fallback, but alpha-stage and Windows-only.
GPU-accelerated 30K object rendering is impressive, but the space tracking category already has Heavens-Above and N2YO.
Metal rendering is nice, but Neovide already does GPU acceleration cross-platform.
Research-grade ray tracer in Julia; spectral path tracing on AMD/NVIDIA/CPU, no mesh export.
ControlNet for architects that skips the local Stable Diffusion setup headache.
Renderer-agnostic core swaps WebGL/Canvas/WebGPU without touching state — rare architectural discipline.
