🚀 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

It is now possible to create 360 equirectangular VR 8K seamless videos from a single image! 😃

Thanks to AI, designing my dream kitchen is now easier than finding the right lid for Tupperware!

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.

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👇

[Philip Rosenbaum @philrosenb]

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
