@stroughtonsmith Erm, is it real 3D?
@gklka it's Metal, it's not RealityKit

Hadn't tried the visionOS build, but it works too.
With a caveat.
visionOS is far more fragile to anything like 3D rendering. Saturating the GPU like this slows the compositor to a slideshow, and even got to a point where Metal was leaking out of the window into the OS and I was seeing squares of corrupted video memory in front of me until I got the equivalent to a SpringBoard crash.
Functionally, this could be a visionOS app.
Practically, no.
@stroughtonsmith have you tried closing your eyes to make it render faster?

@edmn the OS is doing it for me

@stroughtonsmith Too bad. These 3D editors are perfect fit for Vision

You can see here that the moment I invoke the raytracer, everything goes to shit on visionOS. The userspace went down right at the end of the video, where it cut
What if you could step into your Bryce scenes?

@tsturm @stroughtonsmith Yes, of course. We had radically different goals though. Producing what Steve has in a day, even if it’s just a throw-away bit of fun, remains striking to me.
Makes you wonder who's code the LLM learned from. Is there a full metal project out there already? Does it have similar default menu elements? How much of it is novel here? How much more optimized would it be hand crafted? Is it negligible?

Pretty much everything I've worked on with Codex up to now has been stuff I could have built myself, within my area of expertise (or learnable), it just would have taken weeks or months.
This 3D scene app is something I never would have been able to build myself. I would have needed a team of rendering experts with domain-specific knowledge and human-years of research

I love how visionOS, uniquely, *explodes* when rendering goes wrong.

@stroughtonsmith your results are amazing, but got me curious about Codex writing Metal, so I asked it to make a solar system simulation
After two hours of back-and-forth it still can't seem to texture a sphere in a way that doesn't cause the lighting and texture to rotate with the view
I gave it six goes at trying to get the bloom effect correct, but in the end had to paste an entire blog post into its context about how to render bloom in Metal

@simsaens I could suggest things, but if you want to take this offline, DM me your iMessage maybe

@stroughtonsmith watching you build these things over the past few weeks has been amazing. Do you think there is a chance you will create a blog post or have a thread with more details about how you are promoting the AI agents?

@jlaase I did blog about it, and it has one prompt session transcript: https://highcaffeinecontent.com/blog/20260301-A-Month-With-OpenAIs-Codex

@stroughtonsmith for my use, the "vibe Coding" is most helpful for edge cases where it would be a huge rabbit whole to implement a relatively small feature, so we're aligned there. Thank you for sharing your work online

Hello [MacBook] Neo.
So now that visionOS 26 lets you spawn immersive scenes from UIKit apps, I had Codex implement me an immersive scene using Metal and CompositorServices that mirrors the in-window viewport and lets you live in your scene
It's real frickin cool.
The raytracer might be off limits for visionOS, but there's a lot of interesting stuff to do in other areas

@stroughtonsmith to be honest, that concept might be one of the greatest use cases for Vision Pro. Imagine two controllers in your hand for much more precise input and you've got an awesome product

@gklka I blame you

@stroughtonsmith I imagine this screen still haunts some Apple engineers

I figured I needed some kind of glass shader
@stroughtonsmith but is it Liquid Glass
