We use Mesa's gallium swrast to render as the driver with Filament's backend set to GL. We provide a few scripts to parse the tests (as jsons) and run gltf_viewer to produce the rendering.

# 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.
