@tojiro Have you done any additional work on WebXR + WebGPU?
In particular was wondering about:
- depth24plus as the depth format ... I use depth32float with reverse Z everywhere. The guidelines suggest the depth buffer should be accurate for the given projection matrix, so is reverse Z off the table?
- having to create new texture views, view descriptors, color attachments for every single frame seems terrible from a GC point of view? I usually manage all these statically.

@unconed@mstdn.io I haven't been able to give it much attention since getting the basics running behind a flag, unfortunately. To your questions: Reverse Z should work, pass a larger number to the renderState's depthNear than depthFar (which is explicitly allowed by the spec) https://immersive-web.github.io/webxr/#dom-xrrenderstate-depthnear
