well, not really. you load the data and pass it to the GPU. There's no real work to do on the CPU. I'm not saying it's trivial to write a viewer but to doesn't require performant code.

I've written a GLTF viewer in JavaScript. You parse the JSON, pass the data to the GPU, apply shaders. It requires knowledge of how to render 3D and PBR but it's a day or 2 project to get working if you know the topic and no part of it requires any perf.

So you're saying this could only properly be done with Rust. Hear, hear.
