Planned
OSC to command bridge, video output, and mocap input for live performanceThe same codebase drives a desktop editor and is designed to be hosted elsewhere. That constraint shapes everything: no layer assumes it owns the window, the GPU, or the clock. It is research in progress, not a claimed public release.
The workspace is layered so dependencies point one way, and the boundaries are written down as invariants rather than conventions. Breaking one is treated as a bug.
- wmmd-render · backend-agnostic interface, no GPU dependency
- wmmd-render-wgpu · every GPU pass, never owns the swapchain
- wmmd-runtime · CPU simulation, never loads files
- wmmd-asset · PMX/PMD, VMD, texture and material analysis
- wmmd-clock and wmmd-audio · standalone, zero cross-crate deps
Rendering is checked headlessly against approved reference frames, physics has its own verifier, and a fix reproduced with one model must be expressed generally — no per-model special cases in shipped code.

WMMD architecture: a hostable MMD runtime
Why the engine is split into layered Rust crates with hard dependency invariants, so the same code can drive an editor, an AR host, or an offline renderer.
↗WMMD rendering: a toon pipeline verified by golden images
Forward toon shading with WBOIT transparency, ESM shadows, SSAO and RT AO, IBL and bloom — and the headless snapshot infrastructure that keeps it honest.
↗WMMD physics: three backends behind one interface
Bullet as the MMD-faithful reference, a pure-Rust fallback, a clean-room PGS solver, and an XPBD cloth engine — swappable at compile time.
