How to load sampler3D data with URL?

I’m currently working on a project and I use huge volumes. due to browser limitations, I can only create arrays with limited sizes. So, I created a png image that contains the slices of the volume in a tiles manner and wanted to know how to send that to sampler3D.

I suggest normalizing the slices before casting the type to uint8array
