Sounds cool. Too bad it doesn't appear to work on Macs? (Or at least mine -- MacBook late 2016, macOS 10.14.3, Chrome 72.0.3626.109.)

Tried opening in Safari too, and the page is just white -- doesn't even load the menu interface or anything.

Hi, I'm the developer of the site. Safari doesn't seem to support WebGL2, which is why it shows up pure white. There should be an error message, but that appears to have broken at some point. Could you press F12 and tell me what the console says? I don't have a Mac myself, so I can't debug.

Chrome should be working. If it's rendering gibberish, could you go to http://webglreport.com/?v=2 and tell me what "Unmasked Vendor" and "Unmasked Renderer" say? There's a known ANGLE bug on AMD/Mac that I need to work around, but it causes performance issues so I try to limit it to platforms I know are broken; it sounds like you have a configuration that isn't in the whitelist.

Safari shows the red bar error message now.

In Chrome:

  Unmasked Vendor: Intel Inc.
  Unmasked Renderer: Intel(R) Iris(TM) Graphics 540

And on your site, immediately upon loading the console is giving me 29 different 404 errors across different filenames like:

  VM208:1 GET https://storage.googleapis.com/znoclip/z.noclip.website/j3d/smg/ObjectData/Hanachan.arc 404
  (anonymous) @ VM208:1
  i @ string_decoder.js:135
  e.getModel @ string_decoder.js:135
  c @ string_decoder.js:135
  e.spawnObject @ string_decoder.js:135
  e.spawnZone @ string_decoder.js:135
  y @ string_decoder.js:135
  ...
  string_decoder.js:135 Could not fetch archive 
  j3d/smg/ObjectData/Hanachan.arc 404

Hope that helps. Good luck! :) The idea sounds neat.

The 404 errors are to be expected. Several users have reported an issue with the Intel(R) Iris(TM) Graphics 540 chipset, but unfortunately as I do not have hardware to test with, I am unable to debug it. But I suspect it's a driver issue. Let me try a few different ideas based on something I read online.

EDIT: I attempted to push one workaround. I cannot test it here, so please let me know if it helped.

Glad you're trying to fix it! Just emptied my cache and refreshed but no change in Chrome or Firefox, sorry... happy to check again in the future, just click my profile and e-mail me directly there

Bummer that drivers are that sensitive... I remembering the nightmare of dealing with different browsers/OS quirks for the HTML5 audio API, but at least I could test everything using virtual machines... graphic cards sound like a whole other level of hell. I had no idea.

Just came back to this out of curiosity... it works now! However you did it, thanks :) super-cool!

Also having the rendering problem on Mac for some but not all levels (Zelda OOT is broken, Banjo Kazooie works okay):

Unmasked Vendor: ATI Technologies Inc. Unmasked Renderer: AMD Radeon Pro 555 OpenGL Engine

What's interesting is that it worked on my computer before reinstalling MacOS on new hdd, and now it stopped working, showing malformed geometry.

JS console output: "Batch 2 does not have TEX0. WTF? / Attributes: 600 index.js:14" (and the same for different batch ids) ATI Technologies Inc., AMD Radeon HD 6750M OpenGL Engine

I broke the workaround for Mac AMD accidentally in the process of trying to fix Mac Intel. Should be fixed now. The "Batch 2 does not have TEX0" message is a normal warning for Luigi's Mansion.

Same here.

FF and Safari don't work at all. Chromium shows something, but it isn't clear if I am seeing what is intended as the site has little to no information as to what it is.

It's supposed to look like a video game level. There are a lot of different hardware configurations. Could you please go to http://webglreport.com/?v=2 and tell me what "Unmasked Vendor" and "Unmasked Renderer" say?

For Firefox, could you open up the console with F12 and tell me what that says as well?

It's working on my Macbook late 2013 / 10.13.6 / Chrome 72.0.3626.109
