I never really thought about it before, but multitouch is actually legit for 3D modeling tools, maybe even better than a desktop. On a Mac, you need to hold modifier keys (or buy a multi-button mouse) to do everything you want with the viewport, but on touch you can orbit, pan, zoom, and multi-select very easily. If you special-case the stylus too, like I am, it feels very powerful.
Almost all of this extends to spatial computing, though visionOS struggles a bit with two-hand gestures
@stroughtonsmith I mostly use Shapr3D on my iPad for CAD stuff I am so much faster than on my Mac with the same app.

@stroughtonsmith it’s great to use with the pencil and as you said touch for navigation.

@gregggreg oh no this runs on devices before that. I think it needs an M1/A14-class device or higher

@gregggreg do you have a source for that? I haven’t seen that documented

"...which is that the iPhone 16 Pro does not support background GPU. I don't know of anywhere we formally state exactly which devices support it, but I believe it's only support on iPad's with an M3 or better (and not supported on any iPhone)."

iPadOS has never been better for rich, complex, desktop-class apps. Almost all of the old barriers and blockers are gone.
Sadly, Apple waited until most developers had run out of patience with the platform.
If this thing had Xcode, a real Xcode, it would be effectively complete

Even my iPhone 12 Pro Max can raytrace!
Which I guess is not all that surprising, considering the A14 chip is the same generation as the M1

@stroughtonsmith The moment you vibe code it and it doesn’t have a modal pop up whenever it connects to the watch, we will know we’ve achieved the singularity

@stroughtonsmith Petition to rename all A Series SoC as M Series "Mini".
A14 -> M1 Mini
A18 Pro -> M4 MiniThe benchmarks don't lie.

That’s a whole lot of raytracing from a little iPad. Biggest render to date, at 5120x2880 — took about an hour to get to the final pass.
Crashed right at the end, so I didn’t get to take a picture of the final output 🥲
The raytracer still needs a bunch of work, but it’s more and more capable day by day

@stroughtonsmith Much like with the windowed UI, I feel like Apple is putting in more work avoiding Xcode while previously making Swift Playgrounds nearly capable enough. It seems simpler to just have Xcode at this point.

@stroughtonsmith yes please! Would be interesting how much of the toolchain can be included out of the box (of course not AppStore compatible)

I was tired of running into raytracer resource limits, so now it uses wavefronts and a scheduler with a 4+ Kloc rewrite. Seems a lot better for complex scenes and lots of glass. All that work spent optimizing the previous renderer's performance ramp and failure recovery pays off now that the new renderer is so much more robust
