Progressive loading for textures #54

Closed munrocket closed 3 years ago

munrocket commented 4 years ago

In WebGL applications we facing with issue that downloading from server and loading texture to GPU is pretty slow operation. In web we have progressive JPEG/WEBP but we can't access to level of details and need to create 2-4 versions of a file each of which laready has progressive format.

In same WebGPU issue https://github.com/gpuweb/gpuweb/issues/766 they suggested to me Basis and your repo. But looks like basis should be smaller in size or inside js fetch API?

The mipmap bias is outside the scope of WebCodecs (or really any spec, it's part of the app/engine), but progressive loading in general is being considered as part of the ImageDecoder API.

That is being discussed in https://github.com/dalecurtis/image-decoder-api/issues/3.

This could be a good improvement, feels like webgl/webgpu not so good as page render without it.

Thanks for the link. It's good to know folks would be interested in this.

This is not popular, but works like charm. I wonder why we still doesn’t have it. Texture load for 4k images takes lot of time.

The ImageDecoder spec is now landed with facilities for decoding progressive images from a readable stream off the network. https://w3c.github.io/webcodecs/#typedefdef-imagebuffersource

I don't think there's another clear action item for WebCodecs here. Please re-open if I've overlooked anything.
