webgpu-feature-detector

Prototype for a webgpu feature detector library, at the moment for texture formats.

Example:

import { getTextureSupportedFeatures } from './webgpu-feature-detector.module.js';

const adapter = await navigator.gpu.requestAdapter();

const info = getTextureSupportedFeatures(adapter.features, 'rgba32float')
console.log(JSON.stringify(info, null, 2));
Copy

Might print something like:

{
  "supported": true,
  "multisample": false,
  "resolvable": false,
  "blendable": true,
  "filterable": true,
  "colorRenderable": true,
  "renderAttachment": true,
  "copyExternalImageToTexture": true,
  "storageReadOnly": true,
  "storageWriteOnly": true,
  "storageReadWrite": true
}
Copy

NOTE: DO NOT USE THIS LIBRARY (recommended)

This is/was an experiment in supporting something like D3D12's device->CheckFeatureSupport

The question is, is it really useful? The problem with this API is it ends up suggesting you should check for things you really should not likely be checking.

Example: whether or not copyExternalImageToTexture is supported. Only a single format, 'rg11b10ufloat has optional support. It's relatively rare format. So you're using that format then you might want to check but otherwise, checking for common format would just be a waste of time.

Similarly, filterable and blendable. The only format that's generally affected by this is rgba32float. So you should not be checking other formats.
