Web3D
A multi-category corpus of interactive 3D object assets — programmatic models, functional assemblies, deterministic behaviors, and expert-defined evaluation.
Overview
Copula Web3D is a structured training and evaluation corpus centered on multi-category interactive 3D object assets — spanning architecture, machinery, optics, aerospace, and biomimetic mechanisms — for reconstruction quality and complex interaction.
Each datapoint starts from task constraints, proceeds through programmatic modeling and assembly, and yields a 3D interactive artifact that opens in the browser — rotatable, disassemblable, and operable — with multi-view state screenshots, a continuous production trajectory, and itemized expert evaluation.
The focus is behavior construction, not static assets: moving complex mechanisms, real assemblies, and operable interactions. A single case can involve a hundred named parts, a dozen material and lighting responses, and a full set of deterministic action states. Scoring anchors are fitted to human 3D and manufacturing expert judgment.
Built for
