Upgraded my raytraced renderer with bounce lighting and true reflections. Now it looks pretty legit!
The floor also needed some bounce lighting

'Could somebody with no programming experience recreate Photoshop with an LLM?'
I have absolutely zero Metal and near-zero 3D modeling experience. I know the basics of how to use a scene editor, and the names of rendering terms.
And I effectively vibecoded all of this in less than half a day with Codex 5.3 Medium, based on screenshots of a cool-looking app I've never used (Valence3D) and just a general sense of what a 3D app should do

Raytracing uses every last ounce of my poor M1 Mac mini's GPU. It has never seen such a workout

@stroughtonsmith I don't think hardware raytracing was added until M3 — that M1 GPU must be cooking!

@stroughtonsmith Did you build the path tracer yourself or is that a system library?
And what exactly will this tool do? I assume you're not building a full modelling tool.

@k0bin Codex built it from scratch. I don't know what it will do yet, I'm just experimenting

@edmn yeah it's not using hardware-accelerated raytracing. I don't know enough about the feature to know whether that would even be useful in multi-minute raytracing of static images rather than optimizing things for realtime

Since I am doing this on the GPU, not CPU, finding a way to render complex meshes without blowing the budget is a headache. There's a hard cap on how much work you can do before the Metal driver crashes

@stroughtonsmith add in some radiosity to really test it

@fatlazycat it's already doing bounce lighting

@stroughtonsmith Sounds like you need to buy an M4 Mac mini!

@stroughtonsmith are you using Codex GUI app, or are you using codex trough the Xcode 16.3 AI CLI ?

@guybrooker the Codex app. Xcode has too many guardrails in place

@stroughtonsmith This is what vibe coding should be used for. AI should be used to screw over Autodesk and Adobe

I think I should probably add a denoiser to this…

It’s a warm, sunny day, so I moved outside to sit with the dog. My iPad has a much faster GPU anyway, so rendering works great here side by side with my Mac over VNC. And it’s a nanotexture model, so working in direct sunlight is effectively the same as working indoors

@stroughtonsmith sunny enough to sit outside?! It's 2.8C here. 🥶

@bigzaphod I’ve just had two months of non-stop rain, let me enjoy it

@bigzaphod @stroughtonsmith We’re back to rain today here, but we just ended a beautiful sunny week — got up to 17°C yesterday. Still frosty some mornings though.
It’s been an exceptionally mild winter overall for us: we never even bothered to cover the vents into the crawlspace, or drain and cover the outside water taps for the first time I can remember.
Which sounds nice, but it’s going to be rough come summer — there’s not nearly enough snowpack, which we kinda depend on.

Added some targeted calls to the hardware raytracing APIs, and a toggle switch so I can flip between non-accelerated RT and accelerated RT. There are plenty of bottlenecks in my renderer to stop it taking /full/ advantage of acceleration, but holy heck it’s much faster regardless. This is on the M5 iPad Pro
