Geometry‑Grounded Video Diffusion for 3D‑Consistent World Generation

DreamWorld introduces a two‑stage Geometry‑then‑Appearance pipeline that first generates geometry features for the target viewpoint using a 3D foundation model and then conditions a video diffusion model on these features to produce high‑quality, 3D‑consistent RGB videos, achieving state‑of‑the‑art results on multiple benchmarks.

Why AI Can’t Crack the 3D Kakeya Conjecture – A Deep Analysis of Wang Hong’s Breakthrough

The article examines the century‑old 3D Kakeya conjecture, explains why the problem is dramatically harder than its 2D counterpart, reviews historic attempts, details Wang Hong’s multi‑scale proof that finally settled the conjecture, and argues that current AI lacks the strategic creativity to achieve such breakthroughs on its own.
