Migrating from WebGL to WebGPU turns out to be harder than I expected ๐Ÿ˜ฎโ€๐Ÿ’จ luckily this puzzle is more pleasant.

That's what I've been doing for now, while working on a way to handle headless rendering with the WebGPU API in the meantime. I'm making steady progress but the fact that it's still so new makes it a decent challenge.

gl.texImage3D is not a function error when using with threejs ยท Issue #304 ยท stackgl/headless-gl I'm got this error when init WebGLRenderer object in threejs library. I'm using version 0.171.0 of threejs

This came about because I was relying on this GitHub project for headless rendering with three.js and it turns out it in turn relied on some WebGL1 APIs.

That said I completely understand the choice to drop it, given how much work has gone into supporting WebGPU ๐Ÿ˜…

When I started building EulerStudio I wasn't aware of how much a random choice like @threejs.org dropping WebGL1 support would set me back. ๐Ÿ’€

Early on I thought building a small business would involve a lot of work on interesting problems. And there is a lot of that.

But I found the most important thing is to just keep doing the rote, basic, obvious things. Over and over and over again. ๐Ÿ˜ฎโ€๐Ÿ’จ
