From 18d4c6cf9fabc18282b29d103c8d30024f66e49b Mon Sep 17 00:00:00 2001 From: Valentin Popov Date: Thu, 19 Feb 2026 05:02:26 +0400 Subject: 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. --- crates/render-parity/README.md | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) create mode 100644 crates/render-parity/README.md (limited to 'crates/render-parity/README.md') diff --git a/crates/render-parity/README.md b/crates/render-parity/README.md new file mode 100644 index 0000000..a94520e --- /dev/null +++ b/crates/render-parity/README.md @@ -0,0 +1,16 @@ +# render-parity + +Deterministic frame-diff runner for `parkan-render-demo`. + +Usage: + +```bash +cargo run -p render-parity -- \ + --manifest parity/cases.toml \ + --output-dir target/render-parity/current +``` + +Options: + +- `--demo-bin `: use prebuilt `parkan-render-demo` binary instead of `cargo run`. +- `--keep-going`: continue all cases even after failures. -- cgit v1.2.3
