CMU prof's LLM-built implicit-surface 3D dragon: primitives as geometric prior
keenanisalive · x · 2026-10-10
Part of Keenan Crane's thread on building a 3D dragon as a closed-form implicit surface: lifting 3D from two possibly inconsistent 2D projections is ill-posed, so he uses a geometric prior — "the object is made by blending basic primitives like boxes and ellipsoids." See the thread's first post for full details.
