Utility project to test compute shaders in both wgpu and browsers.
cargo run -- sample.wgslThe file must contain the body of a fn compute() -> f32 { <body> } function, as in return 1.1;.
The result of that computation will be output to stdout.
Use compute.fornwall.net.
The tests/ directory contains a test suite. Each ${NAME}.wgsl file there contains a fn compute() -> f32 function which is expected to return the value listed in the ${NAME}.expected.
Optionally a ${NAME}.nagabranch file contains information about a specific naga branch which will be used for the test.
Execute ./run-wgpu-tests.sh.
It respects the WGPU_BACKEND environment variable, so run e.g. WGPU_BACKEND=gl ./run-wgpu-tests.sh to run against the OpenGL backend.
Information about the wgpu adapter used will be printed to stdout.
Execute ./run-browser-tests.py. That script generates and opens a self-contained test.html file.
