I just updated CellWalk for the M5 Apple Vision Pro! This app really pushes the GPU (entire cells with billions of atoms) and it's a great way to test the M5.
CellWalk on M5 increases resolution and detail 1.5x over M2! Huge. It's super sharp and detailed. Apple Intelligence is also way faster.

I quietly released new features for Apple Vision Pro in the last update: Widgets and on-device AI explanations powered by Apple Intelligence.
I don't have an M5 yet, has anyone tried CellWalk on the M5 Apple Vision Pro?! How is it? more resolution (it should get more by default)?!

Oh! and a Liquid Glass redesign:

Concept chains: Tap and dive deep into unfamiliar terms and concepts. It's pretty cool.. because now everything in the app is interactive, from the visuals to the text itself.

CellWalk is featured in Apple's new article on Apple Intelligence and Foundation Models.
It's a really fun new way to learn about concepts and terms in the app, and I really enjoyed building it.

Getting ready for my talk tomorrow on "Thoughtful Spatial Design" at KWDC25 tomorrow!
Hanging out at Fritz Coffee in Gangnam, Seoul. I love this location, nostalgic vibe.

Ahh!! My app CellWalk is a finalist in this year's Apple Design Awards.
What?! 😮 I'm beyond excited.
Thank you Apple for the honor, and a huge thank you to the incredible people there.

I was honoured to guest lecture on visionOS development and CellWalk at the University of Calgary’s iOS Programming Course. Also got to check out some promising student projects—definitely some Y Combinator potential in the mix!

who else is watching in the vision pro? (sorry for the dirty windows, they only clean them when winter ends!)

I need your help!
I'm doing my first user study (ahhh!!), and I'm looking for a few awesome users to interview. If you have used my app CellWalk (any platform), would you be willing to hop on a zoom call with me for about 20-30 minutes?! I would love to buy you lunch (via PayPal). 🧪 #EduSky

It's the POSCO steel office building.. there is a steel theme, I love it. It's super cozy.

I finally finished a new optimization for CW's render tech on Apple Vision Pro (profiling on an M2 iPad GPU). Super happy because it took a few weeks to implement.
This is the Terarosa POSCO branch (Seoul). Super beautiful place to work

Happy New Year from Seoul
Far from home, I've been reflecting on the years developing CW. Even though the video starts with 2020, the journey began 12 years ago. It will take many more years to achieve the full vision, but in this moment I'm grateful for where we are.

More screenshots. CellWalk's new ambient occlusion technique (right) vs the old one (left). #AppleVisionPro
These are render targets captures.
8spp (old) vs 48spp (new)
1.2ms (old) vs 400us (new)
The new technique is super optimized. Loses final detail though.

Uncropped screenshots. Noise is very exhausting to look at inside a VR device, I'm so happy about this.

CellWalk's new ambient occlusion and noise filters. 48 samples/pixel. About ~300-400us for the ao kernel in this scene. Taken on #AppleVisionPro
Still a few more artifacts to fix, but it looks so *good* now, and it's 2-3x faster than before (and 6x more samples)

This week I focused on CellWalk's lighting on #visionOS (CompositorServices + Metal). Before (very noisy) vs after. I'm really happy with this result, but there is still so much to implement and improve.

WIP: sticking my head inside a cell.
I've been focusing on rendering performance and quality. I implemented a really fast first pass spatial denoiser, improved sampling, fixed rate rasterization artifacts, and fixed sphere rasterization artifacts.

I've been exploring this atomistic bacteria cell model in Apple Vision Pro for hours (the points, if you can see them, are individual atoms).
I just finished implementing rasterization rate maps in all parts of CellWalk's renderer (Metal + CompositorServices)
