3D simulation of autonomous tower crane erecting a full 8 storey steel building in three js
Why this works as a prompt class
Short domain-specific simulation prompts with:
- 1. Agent (autonomous tower crane)
- 2. Process (erecting)
- 3. Concrete deliverable (full 8-storey steel building)
- 4. Stack (Three.js)
…tend to produce coherent multi-minute sequences better than vague "cool construction scene" asks.
