Construct · examples

Describe a thing. Get a hologram, a 3D model and its parts.

Construct lets any AI agent build an animated holographic model of a thing from a description, and takes it further: into Blender and game engines as a 3D model with working parts, or, for a simulation, a model's whole run drawn in time.

From light to a finished 3D model

From light to a finished model

Every construct is also a 3D model. What the agent wrote (named parts in metres, joints, the order they assemble in) exports as one glTF file, and a material map finishes it.

  1. Hologram. Lines of light, as the agent built it.
  2. Plain model. Every part a solid, named object; joints that open.
  3. Finished. Paint, chrome, glass, wood: one map per object, kept beside it.

The page shows four gallery constructs as their exported files: the Land Cruiser FJ62, the James Webb Space Telescope, the Revox A77 and the MiniFreak. Slide each from hologram to plain to finished, open its joints, take it apart, and download it.

Anything you can describe

Each made by an AI agent from a description, in fast or masterpiece mode. Open one to watch it build itself; drag to turn it, R replays the assembly, P shows how each part is known.

Constructs that assemble to music

A construct can assemble across a whole piece of music: the build pauses, surges and flares with it, and you get a video with the music in it. Each opens on its live construct; the film is one click away. Film mode.

4 · Models come alive

Agent-based models, two ways

A NetLogo model can come into Construct as a live simulation you run on the page, or as one recorded run, drawn with time as height.

The model itself runs on the page: rebuilt rule for rule in JavaScript, so you can build new networks, change the settings, run it tick by tick and compare a hundred runs with NetLogo's own, while the construct grows with the run.

Recorded runs, drawn by the bridge

No simulation runs on these pages. Each is one run, recorded in NetLogo by Construct's bridge and drawn from the recording, so its assembly replays the run; the data comes from the run, never from an AI. An AI art-direction pass adds the labels and milestones on top, and a data lock keeps it off the data. The NetLogo bridge.
