I fixed the shader imports in spark.js to work with static analysis, so you can estimate bundle sizes for WebGL and WebGPU.

In practice, though, shaders are imported dynamically. You only pay for what you use, so the actual overhead is tiny.

I've put together an updated version of the Sponza scene with uncompressed PNG and compressed AVIF textures. I wrote about the process and compared the results against KTX.

While working on spark.js, I realized that normal map compression formats weren’t supported in popular frameworks like three.js. I addressed that gap by adding the necessary support to three.js and wrote an article to shed some light on the topic, drawing from my experience in real-time 3D graphics.
