rendiff

Image comparison (diffing) for computer graphics renderer test cases

The algorithm implemented in this Rust library is intended to allow comparing images of the same scene which were rendered using different algorithms, or different hardware, causing small “rounding errors” in either color or spatial position that should be ignored as insignificant.

See the library documentation for details on the algorithm used.

Packages in this repository

• rendiff/ is the library containing the algorithm.
• cli/ (package name rendiff-cli) is a command-line tool to run the algorithm on pairs of image files.
• interop/ is used only for shared code in this workspace.
