Three.js: Improving Shadows

[Usnul]

Better Shadows.

More specifically, i want to see a better shadow-mapping implementation than PCF. Such as Variance shadowmaps. Second, i wish to see a cascading shadowmaps. They were once at the core of thee.js, but fell victim to bitrot and lack of support.

Motivation

Currently shadows require a fair amount of artistry just to make them look okay. If we had a better shadowmap algorithm - a lot of existing problems with acne and filtering would go away. If we had a cascading shadowmap implementation - it would remove the need for artistry currently required to set up shadow camera for each shadow-casting light in the scene.

Such as Variance shadowmaps.

This is supported since R108, see #17171 🎉

Both techniques are now in the library. I think this issue can be closed.

Not to be a spoilsport, but I don't think CSM (Cascaded Shadowmaps) is part of three.js in any way, or did I miss something?
