WebGPU renderer

[pjcozzi]

This is a long-term roadmap issue to track development of NXT, the NeXT generation graphics API for the Web (similar to #797 for WebGL 2).

NXT is the old name. This is WebGPU now. https://en.wikipedia.org/wiki/WebGPU

WebGPU is coming to chromium: https://blog.chromium.org/2021/08/chrome-94-beta-webcodecs-webgpu.html.
They announce a plan to ship in chrome 99, early 2022.

When will it be released?🤔️
I'm... looking... forward....to...it.....😄

Hi @indeexx, we don't have any immediate plans to start work on this. We'll likely update this issue when we do. Let us know if you have any thoughts or questions regarding the implementation in the meantime. Thanks!

[tlightsky]

Do we have some plan for this feature?

It's about to be released. Any progress?

Any news on this?
Chrome 113 is released with WebGPU enabled!

Recently, I have been researching WebGPU, a new API for the web that exposes modern computer graphics capabilities, specifically GPU computing, to the Web. From my understanding, it has the potential to greatly enhance the performance of web-based graphics applications.

The capabilities of WebGPU, such as its high-efficiency rendering pipeline, low overhead, and better hardware utilization, seem to provide an exciting avenue for performance improvements in Cesium. Moreover, with its promise of providing a unified standard across different platforms and devices, I believe it can make Cesium more robust and versatile.

Given the enormous potential WebGPU has to offer, I kindly urge you to consider conducting research into integrating WebGPU into Cesium. Not only could this greatly improve Cesium's performance, but it could also put Cesium at the forefront of web graphics technology, enhancing its reputation as a pioneering platform in this field.

Thank you for considering my proposal. I look forward to witnessing the continued growth and evolution of Cesium.

Any new news?

You can pay attention to GEngine, which has a similar rendering layer package to cesium
example:

			const drawCommand = new DrawCommand({
				vertexBuffers: geometry.vertexBuffers,
				indexBuffer: geometry.indexBuffer,
				shaderData: material.shaderData,
				drawParams: {
					count: geometry.count,
					instanceCount: 1
				},
				renderState: material.renderState,
				shaderSource: material.shaderSource,
				useLight: material.light
			});

Any news on this?
We have fundamentals here https://webgpufundamentals.org/ and there are documents on MDN. WebGPU API has full support on Chrome and Edge now.

@s3xysteak We don't have any concrete plans at the moment, but are definitely excited for this to happen at some point.

If you are interesting in contributing, maybe working on a prototype of CesiumJS using WebGPU, please let us know and we'd be happy to discuss. Thanks!
