Gondola
A low-poly Venetian-style gondola: a long black crescent hull with a toothed steel ferro on the bow, a terracotta passenger sofa and chairs in an open cockpit, gold seahorse ornaments, and a single oar resting in a carved forcola. It comes with a seamless 4 s rowing loop of the oar sweeping in its oarlock.

The brief given to 1DesignTool's “3D object” template:
Gondola for the Canal City 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 Canal City kit (Low-poly style, flat-lowpoly direction): A trading city of bridges and palaces. Use ONLY the kit palette, by name: terracotta #be5937, canal green #3a883a, stone white #f4f1ec, carnival gold #d0a225, terracotta dark #823d26, canal green dark #235223, terracotta light #d08971, canal green light #5db15d, 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 `waterLevel` (0–1, default 0.5) for the kit's "Water level" setting wherever it makes sense on this part, and keep that id.

Note: Size: the hull is 10.8 m long and 1.4 m in beam (about 1.46 m across the rails), about 11.5 m overall from the stern iron to the ferro's cap. The sheer is 0.52 m up amidships and sweeps up to 1.24 m at the bow and 1.02 m at the stern. The top of the ferro is the tallest point at 2.22 m. The oar reaches about 2 m outboard to starboard, so the footprint is not symmetric in x. Origin: x is centred on the hull, y = 0 is the flat bottom amidships, and z is centred on the stern-iron-to-ferro length. The bow faces +Z. No water is included; set the boat into your own canal surface at the waterLevel height. The GLB has 1,868 triangles in 15 meshes, merged per part and colour. It holds one baked 4 s clip, 'scene-motion', and the hull never moves in it. The oar is pivoted exactly in the forcola's notch: it yaws ±12° about the vertical axis and lifts its blade on the recovery about the horizontal axis through the same point. The exported static node pose is the t = 2 s frame (blade lifted), because three-check exports after its determinism seek. waterLevel (the kit's 'Water level') sets the canal surface from 0.12 to 0.32 m above the bottom. It only changes the oar's rest pitch, so the blade tip dips 5 cm under that surface at the catch; the hull is not repainted. length sets the hull length (9.5–11.5 m), ferroHeight scales the bow iron (0.7–1.15 m), and strokeSwing sets the oar's sweep (0–15°). Params are baked into the GLB at their defaults and only change geometry when the scene is rebuilt in the viewer. Only the defaults were captured by three-check; the param extremes were reasoned through in code but not rendered. The design is stylised: it has no gondolier, no felze cabin and none of a real gondola's port/starboard asymmetry, and the ferro is drawn slightly tall so it reads at thumbnail size. Every material is named exactly after a kit palette colour (7 of the 12 are used). The exporter writes one material per mesh, so a colour name repeats across materials: recolour by name. Fix rounds: (1) the keel was made to climb almost to the sheer at both tips, giving the crescent rocker and pointed ends (the first pass had blunt vertical ends and read as a rowing boat); the ferro was enlarged and changed from stone white to mid grey so it reads against the pale stage; (2) the seahorse outline was redrawn and shrunk, because the first version read as yellow lumps, and the hero and front views were reframed. glb-lint: 0 errors and heuristic warnings only (material count and duplicate materials from the per-mesh materials, nested cockpit and seat parts overlapping, rails, ornaments, irons and forcola flagged as 'detached' although they sit on the hull, and a height above the direction's 1 m reference). The verdict reads UNVERIFIED only because no host requirements contract was supplied. plan-check passes on a copy with the ids de-hyphenated; its part-id regex rejects the hyphenated slug ids this library requires, which three-check accepts and the GLB reload preserves.
About the Gondola 3D model
Gondola is a free animated low-poly 3D model from the Canal City set. It measures 2.6 m × 2.2 m × 11 m (W × H × D) at real-world scale and is built from 1,868 triangles across 15 meshes, with 11 named parts and a baked animation (4.0 s). Download the 176 KB GLB and drop it into three.js, React Three Fiber, Godot or Blender — free for commercial use, no attribution required.
- Is the Gondola 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), 176 KB: 1,868 triangles, 4,190 vertices and 15 materials, modelled in metres at 2.6 m × 2.2 m × 11 m.
- Is Gondola 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 Gondola 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.
