#62Looks good the few seconds it works here. Then stops working and I have to close the tab and reopen for it to work again for another few seconds. Firefox, Windows 11, Nvidia Get the following in the console when it stops working: Uncaptured WebGPU error: Buffer binding 2 range 138024504 exceeds `max_*_buffer_binding_size` limit 134217728 Uncaptured WebGPU error: Buffer binding 1 range 138024504 exceeds `max_*_buffer_…
It looks like a webgpu driver issue - can you tell me what model of graphics chip you're using?
RTX 5090 with 610.62 drivers, Windows 11 25H2, Firefox 153.0b9.
FWIW I tried the other one linked here[1] which also throws the same error and stops. Using the same engine perhaps?

#63It’s beautifully done. A few questions I noticed that complex patterns - marble, some paintings, some stained glass - are rendered in what seems like stretched, hazy ellipses. Is that the fundamental building block of a splat? Also, I was interested if any specularity would be captured by the splat. Or any other aspect of the building which shifts from viewpoint - like lights reflected on the marble floor, or where a…
Splats can indeed come with view dependent colors to represent lighting, reflections… Those are captured in values called spherical harmonics of different levels 0, 1, 2, 3 representing different aspects like diffuse, directional lightning, highlights… Not all splat reconstructions come with spherical harmonics though. And they add rendering overhead.
Besides spherical harmonics splats are also good at representing high frequency detail that is harder with traditional meshes: Hair, clouds, vegetation… notice how trees in these reconstructions already look much better than in google maps / earth 3D views.

Hmm, today it works all of a sudden. No changes, no reboots, no new drivers, not restarted Firefox either. Just repeated what I did yesterday: open the link in a private window.
Yesterday when it didn't work I did try multiple times, and as mentioned that other site as well.
Guess Firefox on Windows has some flaky WebGPU support?
edit: must be, worked fine a couple of times, then it stopped with same error as before even after multiple attempts.

thanks for double checking, that's very good to know!

#66Combining the interior and exterior captures sounds like the hard part. How did you get the two sets registered to each other?
Anchor points on the windows!

#67Unreal. It’s been years since I’ve been here. It’s crazy the fidelity you can capture. Stunning work. Unrelated silly question. Are you the same Vincent Woo who went over the whole unit combination story on Medium of a supervisor?
yep
