3Dガウシアンスプラッティングの論文が最初に発表されたのって2023年8月。ほんの2年前だよ。その後の進化が凄すぎて。。。やばい、楽しみ過ぎる。。

🚀 Real-time Gaussian Splat Morphing
Unlike typical cross-fades, this actually moves each splat through 3D world space from source → target positions. @theworldlabs
Features:
-Per-splat speed control with stagger effects
-3D turbulence noise for organic paths
-8 transition modes (radial, directional reveals)
-GPU compute shader - handles millions of splats

中国XGrids社の機器で街路をスキャン → 3D Gaussian Splats化し、夜間に車内からそのデータへリアルタイムで自己位置推定。3Dメッシュとライブ映像が重なり “X線透視”のように見える。RGB+LiDARのスキャナーで3Dマップを作り、Multiset AI がロボティクス/AR向けの機械-readableマップへ変換。
3d visual positioning experiment -- look at the alignment between the 3d mesh and the live camera view. Truly feels magical -- like x-ray vision.
Workflow:
1. Scanned a street in 15 mins w/ xgrids
2. Localized against that scan at night, in real-time, while sitting in a car
The xgrids scanner (w/ rgb + lidar) is perfect to build maps for humans (3d gaussian splats). Then multiset ai makes it easy to build machine-readable maps for AR and robotics to figure out exactly where they are in 3d space with cm-level accuracy.
