- Modify the compare script to output more details of a comparison. This will include the source/golden directory, the comparison directory (the new renderings), and a file path to difference images if the golden does not match the rendered image. - The image_diff script can now output a TIFF that is the difference of two input TIFFs. - Add a viewer for examining the differences between rendered output and golden images. - The viewer consists of a simple server of web API endpoints for querying difference results (along with rendered images in TIFF). - And a web-based (html + lit-element) UI for looking at the rendered images and differences.
Rendering Difference Test
We created a few scripts to run gltf_viewer and produce headless renderings.
This is mainly useful for continuous integration where GPUs are generally not available on cloud machines. To perform software rasterization, these scripts are centered around Mesa's software rasterizers, but nothing bars us from using another rasterizer like SwiftShader. Additionally, we should be able to use GPUs where available (though this is more of a future work).
The script run.py contains the core logic for taking input parameters (such as the test
description file) and then running gltf_viewer to produce the results.
In the test directory is a list of test descriptions that are specified in json. Please see
sample.json to parse the structure.
