I added a new open source app, LaserPointer, to ARKitVision (link in comments). This has a simple setup for tracking the Logitech Muse stylus, and uses the primary button to change laser beam colors.

Apple Vision Pro Developer Strap (2nd Generation) just arrived.
Curiously, it has some more more metal near the connector on both sides, and is just a bit visible on the right.

MeshInstancesComponent Stress Test in visionOS 26.
Here I'm using MeshInstancesComponent with 160,000 instances to create a 4-iteration Menger Sponge / Sierpinski Cube. Since each cube is rather simple, I'm able to squeeze this many instances. in one RealityKit Entity.

WWDC25 just dropped their “group labs” you can sign up for. I’m basically planning to do all of them! So excited to see what the next versions of visionOS, iOS, macOS, watchOS, tvOS, Xcode, and Swift Playgrounds have in store for us!

Here’s a scene from my latest visionOS project. This has particle emitters from the space all around you, and from your hands, and has a mirroring representation of you. I’m using this as a stand in for another visionOS person to get a feel for how my scenes will feel to share them with others.

Preview of my latest open source for visionOS, macOS, and iOS: EntityView
Why
1. Multiple overlapping RealityViews on visionOS aren’t really possible on iOS and macOS
2. Combining several clusters of Entities in the same RealityView doesn’t have a good pattern
What would you want to add to this?

Since discovering that I can bring .STL files directly in to RealityView with ModelEntity, I’ve started using OpenSCAD for some of my layout thinking. This “programmer” style tool suits my thought process better for laying out and manipulating 3D elements.

Some days I am very productive with my hobby projects. Today was not one of those days. But, I did decide on what numbering system my aliens use. Can you figure it out?

Here’s another video from my new game. I added a Patrol Component and System and got some fun bouncing behavior when I gave them a goal above the floor level. I think I will keep this happy accident!

ARUnderstanding 2.0 is a bit of a hefty update.
Here are the features planned:
* updated visualizations for most of the visionOS anchors
* ARUnderstandingSession infrastructure for a more efficient runtime
* PackCodable to transform anchors into small Data
Here’s a peek of the visuals:

I worked thru a lot of different interactions while building Cards Together this year. I’m really happy with where this landed:
Tap to flip a card
Drag to move a card (and any cards on “top” of it
Drag around to gather cards, swipe into it to move the whole stack
Drag into a stack to fan them out

Added an auto finish to Cards Together when playing Klondike (Solitaire). It’s pretty satisfying. 🙂 🃏 #ios #BuildInPublic

Announcing HandGesture #openSource Swift package for #visionOS with an API you can build on to create semantic hand gestures.
Here’s a video of my HandGestureApp I’ll be adding to ARKitVision soon showing off the different included gestures.

I updated my TargetPractice #openSource app with my new HandGesture Swift package using the FingerBlasterGesture, with some unexpected results. I need to add a bit of state to only fire once for each thumb down gesture! 😂
