Valentin Popov 18d4c6cf9f feat(render-parity): add deterministic frame comparison tool
- Introduced `render-parity` crate for comparing rendered frames against reference images.
- Added command-line options for specifying manifest and output directory.
- Implemented image comparison metrics: mean absolute difference, maximum absolute difference, and changed pixel ratio.
- Created a configuration file `cases.toml` for defining test cases with global defaults and specific parameters.
- Added functionality to capture frames from `render-demo` and save diff images on discrepancies.
- Updated documentation to include usage instructions and CI model for automated testing.

Render Parity Dataset

This folder stores parity-test input for crates/render-parity.

  • cases.toml: list of deterministic render cases.
  • reference/*.png: baseline frames captured from the original renderer.

Expected workflow:

  1. Capture baseline PNG frames from original game/editor for each case.
  2. Add entries to cases.toml.
  3. Run:
cargo run -p render-parity -- \
  --manifest parity/cases.toml \
  --output-dir target/render-parity/current

On failure, diff images are saved to target/render-parity/current/diff.
