It has worse quality than something like a Lanczos filter, and it requires computing image pyramids first, i.e., it is also slower for the very common use case of rescaling images just once. And that article isn't really about projected/distorted textures, where trilinear filtering actually makes sense.

Have you never downscaled and upscaled images in a non-3D-rendering context?

I very much do want that since the WebGPU API is far easier and nicer to use than Vulkan or OpenGL. Also, it makes apps much more accessible to distribute them over web, and it is much more secure to use web apps than native apps. Unfortunately WebGPU is way too limited compared to desktop APIs.

One of the turning points for the worse was the introduction of WGSL. Before WGSL, you could do lots of stuff with spirv shaders because they weren't artifically limited. But with WGSL, they went all in on turning WebGPU into a toy-language that only supports whatever last decades mobile phones support. I was really hopeful for WebGPU because UX-wise, it is so much better than anything else. Far better than Vulkan or OpenGL. But feature-wise, WebGPU so limited that I had to go back to desktop OpenGL.

In one way WebGPU really has become a true successor to WebGL though - it is a graphics API that is outdated on arrival.

"Using a pointer in a shader - In Vulkan GLSL, there is the GL_EXT_buffer_reference extension "

That extension is utter garbage. I tried it. It was the last thing I tried before giving up on GLSL/Vulkan and switching to CUDA. It was the nail in the coffin that made me go "okay, if that's the best Vulkan can do, then I need to switch to CUDA". It's incredibly cumbersome, confusing and verbose.

What's needed are regular, simple, C-like pointers.

I wish AMD&Intel would extend compute shaders with pointers&pointer casting, arbitrary large buffers instead of just 4GB, device-wide sync, and function pointers. Those are kinda my must-have functionality. Even better, just use C++ for compute shaders.
