Visual essay: AI cut 3D draft generation by 4 orders of magnitude, value shifts to topology
cpaik · x · 2026-11-04
An interactive visual essay, AI Topology, maps how AI reshaped 3D content: since 2022, generating a rough 3D draft went from 90 minutes to under a second — about four orders of magnitude — at well under a dollar per draft. But structure (topology) remains the bottleneck deciding whether a shape can be animated, edited, simulated, or manufactured, and value is shifting there.
Key threads:
- Create: drafts are nearly free; progress now goes into detail, not speed.
- Code: frontier models write CAD scripts and drive 3D tools, producing editable structure; leaders are tightly clustered.
- CAD: engineering still demands exact structure; no major vendor generates finished parts, so value sits in the CAD kernel and design history.
- Games: AI-made content spreads through releases while developer sentiment sours; clean topology, rigging, and style consistency remain open problems.
- Simulate: interactive world models became paid products and drew a multibillion-dollar acquisition, though pixels-vs-durable-3D is unresolved.
