- LowLevelMesh with disconnected geometry
- Marching Cubes + SDF for vertex positions
- Vertex normals from SDF gradient
- Polynomial smooth-min to blend the shapes

Beta 5 fixed the manipulation bug that I talked about in beta four 👍👍

Porta Nubi is getting more and more reviews, and it’s so rewarding to see I’ve reached my goal of creating a fun spatial experience 🕹️

It’s incredibly motivating to keep building for visionOS 👨‍💻

Downloading visionOS 26 beta 4 🫡

Xcode 26 Beta 4 is also available!

Still no Paris ;(

Here's a simple burn fade example. The ShaderGraphMaterial directly sets the color and opacity from the UV2 attribute of the LowLevelMesh vertices and the Metal compute shader updates those color/opacity values

My NEW app Metaballs: Spatial – coming this fall to visionOS 26 – got some MASSIVE updates this week🤯

I think I also had to disable user interface debugging. It helped on iPhone but not on Vision Pro.

LowLevelMesh Torus Spinner
- incrementally adds vertices/indices (or shifts the indexOffset when removing)
- multiple layers of varying opacity and minor radius are stacked with additive blend mode for the glow effect

I have the same issue. There are some Settings that can make things better like disabling gpu frame capture. However debugging for me on Vision Pro has become terrible for this reason.

Alright XR peeps of Bluesky — I've got something NEW for you. Sneak peek at Metaballs: Spatial for Apple Vision Pro. This might be the most amazing app I've ever built 🤯

Will be on vacation ;( hope they do the same in Paris

RealityKit experiment #71

- Loads mesh & texture from USDZ
- LowLevelMesh verts use float4 color+alpha in uv2
- ShaderGraphMaterial blends texture with uv2.rgb, sets opacity from uv2.w
- Metal Compute Shader animates uv2

There are a ton of deals to be had today and tomorrow - don't miss your chance to find some apps and tools you can't live without!

Thanks so much to @macstories.net for posting!

Porta Nubi is featured on the App Store 🚀

It’s the first time that one of my apps is featured for the Vision Pro and in the US - super happy to see this 🙌

Happy  26 beta 3 day, everyone!

iOS, macOS, visionOS, watchOS

tvOS remains at 26 beta 2
Xcode remains at 26 beta 2

visionOS 26 Beta 3 is available!

I've been asking for RoomPlan on visionOS since day 1 and just noticed this in the documentation 🧐 Looking at the archive of the website, the deprecated tag has been here at least since visionOS 2. I really hope we get this framework in visionOS 27 🙏

5DPlan version 1.8 is now available!

What's new:
- Improved detailed PDF reports
- Detailed Wall and Window Measures

It has never been easier to align 2D and 3D content, thanks to the new depth alignment features in SwiftUI Layout.
