RL Grows a Third Dimension: Why Text-to-3D Finally Needs Reasoning

A mechanism-first reading of why reinforcement learning for text-to-3D generation needs specialized rewards, token-level optimization, reasoning-heavy benchmarks, and coarse-to-fine training.

SceneMaker: When 3D Scene Generation Stops Guessing

SceneMaker shows why open-set 3D scene generation needs separate priors for de-occlusion, geometry, and pose instead of forcing one pipeline to guess everything at once.
