WIP: This is magic! I'm walking around a bacteria cell in #AppleVisionPro!!! It's an atomistic cell model (you can see atoms when I get close to something). I just got this prototype working in CellWalk's renderer. #science #biology #scicomm #education #gamedev #apple

I'm using the new Metal passthrough mode in vision OS 2 beta. There is still a great deal to do. I need to sort out a number of bugs and limitations (which Twitter compression kindly hides), and get more of the rendering performance features working with foveated rendering.

Download CellWalk on the iOS and Apple Vision Pro App Store (older portal mode, which is like looking at those 3D movies, which is still cool):

@CellWalkApp Wait a minute. Are the innards to scale? I would have assumed there was a lot more empty space.

Yes, cells are super dense. @dsgoodsell shows this in his illustrations of cellular environments (he's one of the scientists who built the cell model we're using in CellWalk). This is my favorite painting, a cross section through a neuron's axon (and topical given your background!)

Zooming around a bacteria cell. It's so cool I just got the cell imported (including lipids) and rendering correctly with the new rendering engine (it's called Angstrom). 3x performance boost! So much detail (too much?!) #screenshotsunday #gamedev #scicomm #xcode #swiftlang

Suddenly a wild Mycoplasma appears! I'm getting ready for #WWDC23. This is going to be insane in the Apple VR headset. So excited! 😆 It's a 250 million atom bacterial cell model rendered in real-time on an iPad (or iPhone). #gamedev #scicomm #vr

Zooming around a 300 million atom bacteria cell on my iPad in a beautiful cafe (my favorite ever actually). I was working on an update for the slice UI today. The cafe is Terarosa on Jeju island S Korea (southern branch). Good coffee, but an even better atmosphere! Looking forward to home though :) CellWalk #scicomm #gamedev #ipad

Back on the water with the Viceroy prototype. Man I love this job. I'm not sure people realize just how big this vehicle is... something you need to see in person.

How a Death Row Inmate Found Peace Before Execution “Every day when the cell door closes in the evening, I thought, this is my grave. But now when the cell door closes, I close my eyes and this has become my Bodhi tree. Prison is an extreme situation in so many ways. The sense of ‘I am not free’ is the deepest suffering in a human being. People cannot understand this unless they see what happens there.” Sadhguru

Some wandering around a WIP map for this #screenshotSaturday ^^ I'm drowning under some construction works irl so i rest a little... by doing construction works in my prototype >< ! Main project : #gamedev #soloDev #indiegame #game #AnimeStyle

This is Huge! RFK Jr. says he will be working with states to get cell phones out of schools. “Cell phones produce electric magnetic radiation, which has been shown to do neurological damage to kids when it's around them all day.” “It’s also been shown to cause cellular damage and even cancer.” “Cell phone use and social media use on the cell phone has been directly connected with depression, poor performance in schools, suicidal ideation, and substance abuse.” “The states that are doing this have found that it is a much healthier environment when kids are not using cell phones in schools.”

Hood classic Throw Back Thursday Don dada letter to god He actually got a deal off this with Jeezy. “I don't get it lord talk to me How can I have faith in something I just can't see This is a small example son listen very closely You can't see oxygen, but you believe you can breathe” This real rap 4 ya.

Twenty-five years of working with RNA taught one medical biochemist three things you should never do with it: modify it, stabilize it, or inject it. The mRNA COVID vaccine did all three, and I asked him to walk me through why that's important. He described RNA as the blueprint of a cell, the instructions it uses to translate into proteins that do the actual work. If that blueprint is modified mid-construction, you don't get the protein you designed. You get fragments, and he said that's what is being produced in the majority of cases after the modification and injection of the spike protein RNA. The greater danger is reverse transcription. When the RNA template persists in the cell long enough, it can be converted back into DNA. A cell with more DNA than it should have is something every physician recognizes. It's called aneuploidy, and it's a transformed cell. It's cancer. He told me that, in his assessment as someone who has spent his career studying exactly this biology, the impact of all of this is beyond a disaster.

Imagine stepping into your embeddings that power RAG. 📚 In this proof of concept, you’re surrounded by courses. Semantically similar ones float right next to each other. I've built an XR prototype with Rémi at In The Pocket where you can stand inside your knowledge base on Apple Vision Pro. Ask a question and the AI lights up the relevant documents in space, so you literally see where your answer comes from. When you ask something specific like "I want to be an astronaut, what can I learn", only a few tight clusters glow. But ask "I'm bored, what could be something fun to study" and clusters across the space light up. #applevisionpro #artificialintelligence #xr #rag

This is insane!🔥 This is a 720p (2D) video I shot of my kids 15 years ago! I used AI to upscale it, depth-map it, & used the depth map to convert it to 3D SBS, & then converted that to Spatial Video for Apple Vision Pro (MV-HEVC). My son is currently a senior in high school, and my daughter is a sophomore in college. This video has complete spatial depth when viewed in the Apple Vision Pro. Obviously, you can't appreciate that via this post. But it's like I'm there & I can see into this room. Talk about giving you the feels.🥹 This can be done with ANY video. 🤯 I'm working on refining the workflow, as it's a bit cumbersome. I plan to share it, but holy cow! I had to post this.

A ~Special~ date with Nikki ~ I wanted to try something doing something really "out there" for this Valentine's. So I went with, "Using hypnosis on a date in Huniepop." This isn't exactly what I had in mind, but it's as close as I can get. I hope you guys enjoy it

It’s an absolutely incredible experience to see in real life at Kennedy in Florida. But I had special SpaceX access in Texas to a Starship launch (2X the power) Where I was allowed to get 4 times closer than NASA allows. Look at how close I was. This was my cell phone. Look at the shockwaves rippling in the exhaust

Another tool that I'm coding: Automatic level theme changer! Makes it easier to prototype levels and experiment with different ideas Visuals for the levels are WIP! This is all working way too well that makes me consider an in-game level editor.. #indiegame #gamedev #lowpoly
