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.

rendiff provides only a comparison algorithm which can use a pass/fail criterion, and a visual representation of the diff; it does not provide any test-framework features like loading expected images and overwriting them, or producing visual reports.

Stability

rendiff is being used within one of my other projects (all-is-cubes) and reliably performs its function. However, there are several features that it lacks, which may result in breaking API or behavior changes in future versions:

  • Customizing the pixel comparison (color value distance) function.
  • Allowance for antialiased edges.
  • Input images of greater than 8 bits-per-component.
