🚀 WIP A 360° 4D Gaussian Splatting video player with a novel approach
My solution: SPAG-4D (Spherical Pixel-Aligned Gaussians for 4D)
🔬 Technical approach:
• Bijective pixel-to-Gaussian mapping - each pixel in equirectangular frame maps directly to a Gaussian
• AI depth estimation converts 360° frames to 3D point clouds
• No iterative optimization needed - milliseconds per frame vs minutes
📦 Temporal compression format:
• Base PLY + quantized position/color deltas
• Int16 position deltas + Int8 color deltas
• 51x compression: 8.1GB → 156MB for 241 frames
⚡ Browser playback:
• NPZ parsing with flate decompression
• Frame reconstruction from deltas in JS
• 500K+ Gaussians at 60fps
🎮 Unity plugin:
• Compute shader reconstruction on GPU
• Custom splat rendering shader (BiRP + URP)
• TemporalNpzLoader for streaming playback

I was interviewed for Sky News on behalf of the AMETHYST team about our trial comparing two psychological therapies for people who hear voices. You can check out the interview and demo of avatar therapy here (1/2)

Excited to announce the integration of OpenAI's DALL-E into my magical VR storytelling tool! 🎨✨ Now, within just 6.2 seconds, witness stunning images transformed into a Triplane-Gaussian 3D model, dynamically illuminated with light attenuation.!
Prepare to be
enchanted!

And yet I saw this quality jump with the work of Louise Birkedal on schizophrenia. Deployed in real health settings. And the results. 🤯 I am sorry the whole session was behind close doors. But I will post here a documentary they are making when is out.
Mandag Morgen inviterer til digitalt læsermøde den 6. september klokken 15:30, hvor jeg glæder mig til at tale med @Therkel - @chris_carlsson og @PeterHesseldahl om fremtidens rummelige internet - Metaverset.

It’s a wrap! We have a deal on the #DSA! Two years after we tabled the proposal 🙏 @SchaldemoseMEP and @cedric_o - and our amazing teams - for great cooperation 🇪🇺
@khora_vr has been shortlisted for Danish Design Award 2022 in 3 categories!! So cross your fingers for us! 1) ‘Better learning’: https://t.co/8fkJICFAfJ 2) ‘Visionary concepts’ https://t.co/CDtImAnWg9 and 3) ‘Healthy life’ https://t.co/wdhVD04ovu #xr#danishdesign
This is the first example I have seen of automatic object substitution to create #augmentedreality that fits within the environment. With a #technology like this, it's up to the creatives to unleash their imagination.

Jeg var i @dr2deadline i går aftes for at tale om de økonomiske og sociale fordele ved at fordele #barslen mere lige mellem mænd og kvinder. Se link i tweetet nedenfor👇
Regeringen åbner så småt op for at fordele barslen mere ligeligt forældrene i mellem. Jeg har skrevet om, hvad økonomisk forskning viser om barselslængder og fordeling i dagens @weekendavisen: https://t.co/Ew1xCZpsst
På dagen hvor @regeringDK har holdt konference om fremtidens Danmark kommer jeg med min Vison for Danmark år 2040. Det sker som indspark til debat og diskusion af pejlemærker i Tigerrådet under @DanskErhverv https://t.co/9MxbEJkK8J #dkpol#dkbiz#tigerspring
