Is the Fountain jets 3D model free for commercial use?

Yes. It is free under the 1DesignTool 3D library license: use it in personal and commercial work — games, apps, websites, renders, ads and client projects — and modify it as you like, with no credit required. What you can't do is re-sell or re-distribute the file on its own or inside a model pack.

What file format is it, and how big is it?

A single binary glTF 2.0 file (.glb), 360 KB: 2,930 triangles, 3,496 vertices and 48 materials, modelled in metres at 3.8 m × 2.5 m × 3.8 m.

Is Fountain jets animated?

Yes — the GLB carries a baked animation (4.0 s), ready to play with any glTF animation mixer.

Which engines and tools can open it?

Anything that reads glTF 2.0. three.js, React Three Fiber, Babylon.js, Godot 4 and Blender import the GLB directly; Unity and Unreal Engine load it through their glTF importers. The snippets above show the exact code for three.js, React Three Fiber, Godot and Blender.

How was the Fountain jets 3D model made?

Claude Code (Claude Opus 5.5) generated it inside 1DesignTool's 3D template from a written brief, then the design kit's checks verified the geometry and the GLB before it was published. You can make your own the same way with 1DesignTool.

Fountain jets

A low-poly park jet fountain: a round stone basin on a paving ring, with eight rim nozzles throwing white water arcs toward a grey centre hub and a tall crowned jet in the middle. The arcs rise and fall in a chase around the basin in a seamless 4-second loop.

How it was made

The brief given to 1DesignTool's “3D object” template:

Fountain jets for the City Park kit. Design it as one clear asset at believable real-world scale for that setting (state the size in metres in meta.notes), with its main parts modelled and named, readable at thumbnail size and from every orbit angle. It moves: author a seamless baked loop (2–12 s) with every pivot exactly at its hinge, axle or swivel, and keep the base still. This is one part of the City Park kit (Low-poly style, flat-lowpoly direction): Green space in the middle of town. Use ONLY the kit palette, by name: grass green #3a883a, path beige #d6c5a9, pond blue #2e67b8, iron black #151619, grass green dark #235223, path beige dark #bda375, grass green light #5db15d, path beige light #ede8de, soot black #1b1b22, warm white #f2ede2, mid grey #7d828c, dark wood #3d2a1c. Every material's `name` must be exactly the palette colour it uses — the GLB carries these names so the kit recolours as one; an unnamed material fails delivery. Kit knob: expose a param `season` (0–1, default 0.5) for the kit's "Season" setting wherever it makes sense on this part, and keep that id.

Note: Size: 3.84 m across the paving ring x 2.48 m tall to the crown at the defaults. The basin is 3.2 m across with its rim at 0.42 m, and the centre jet rises 1.9 m from the hub nozzle. The origin is the bottom centre, resting on y = 0. The fountain is radially symmetric, so +Z is the front by convention only. The GLB has 2,930 triangles in 48 meshes and one 4 s looping clip, 'scene-motion', made of rigid translation, rotation and scale tracks only. In the clip, each arc jet scales in height about its nozzle tip (one chase revolution per loop) and the centre jet pulses twice about its hub nozzle tip. Droplets travel along the arcs and fall from the crown, and the foam ring breathes about its centre on the water. Arc tails stay below the water surface at every pose. The paving, basin, rim, pool, hub and nozzles never move. Every material is named exactly after a kit palette colour; 6 of the 12 are used. The exporter writes one material per mesh, so a colour name repeats across materials; recolour by name. Params are baked into the GLB at their defaults and only change the geometry when the scene is rebuilt in the viewer. Only the defaults were rendered and checked. season (the kit's 'Season') is water pressure: spring (0) runs about 15% lower and summer (0.5) is full. From 0.6, up to 14 fallen leaves (a 'Fallen leaves' part not present at the default) float on the pool. Toward winter (1) the jets drop to about 45% height but never switch off, so the loop always plays. glb-lint: 0 errors and 6 heuristic warnings. Two come from the per-mesh export: the material count and duplicate same-colour materials. One flags non-indexed flat-shaded geometry. One flags overlapping sibling boxes, which are the intended embedded joins of paving, wall, pool and foam. One flags 'detached' parts: the jets and droplets are water in the air by design. The last is a scale warning against a 1 m reference height, but 2.48 m is the intended real-world size. plan-check passes except for its part-id pattern, which rejects the hyphens in the slug-based ids this library requires. three-check accepts those ids, and all 11 survive the GLB reload.
