Hồ Tuyền Lâm, Lâm Đồng

A tabletop diorama of Tuyền Lâm Lake in Đà Lạt: a calm blue lake among pine-covered hills, the Trúc Lâm Zen Monastery with curved tiled roofs, a bell tower, stone steps and flower gardens, a cable car over the canopy and small wooden boats.

How it was made

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

Tuyền Lâm Lake in Đà Lạt as a diorama. A calm blue lake among rolling hills covered in tall pine forest; on the hill above the shore the Trúc Lâm Zen Monastery with traditional curved tiled roofs, a bell tower, stone steps and flower gardens; a cable-car line with a few gondolas crossing the pine canopy; small wooden boats on the lake; light mist. Loop (12 s): the gondolas travel along the line and a boat drifts. Make it a polished, elegant model in the stylised-PBR direction: clean proportions, smooth curvature, soft bevels on every edge, crisp silhouettes and a restrained palette of named materials (name each material for what it is, e.g. "limestone", "red lacquer", "glazed roof tile", "sea water"); every material in the exported GLB must carry that name — set `material.name` on each one, because an unnamed material fails review. It must be recognisable at a glance as the real place. No text, lettering, logos or signage anywhere. Reference photos of the real place are in `reference/` (ref1.jpg, ref2.jpg, ref3.jpg): open and study them before planning if you can view images, and compare your hero capture with them before delivering. Natural sites and large complexes are presented as a tabletop diorama on a clean rounded plinth with slate-grey sides; state the real-world scale and the diorama scale in meta.notes. Hard requirement: the exported GLB must contain AT LEAST 100,000 triangles (target 120,000–200,000) — measure it before delivering. Spend the budget on real modelled detail (roof tiles, carvings, railings, mouldings, rock strata, foliage clusters, water surface, boats), never on invisible subdivision. Keep the GLB under 20 MB: index all geometry, instance repeated parts, no image textures.

Note: Real-world scale about 2.5 km x 1.9 km; diorama 1.0 m x 0.76 m on a slate plinth, roughly 1:2,500 across the plan. Relief, buildings, pines and the cable car are exaggerated several times so they read at thumbnail size, so building proportions are stylised rather than surveyed. 176,162 triangles, 24 named materials, 7.4 MB, no textures. The 12 s loop is a baked clip: gondolas circulate on the cable (one full loop) and the boats drift or bob. The GLB root node is part 'hotuyenlam' because the plan checker rejects hyphens in a root part id; child parts use the ho-tuyen-lam.* ids. The tree, gondola, boat and mist params rebuild the model in the viewer; the downloaded GLB is the default setting. Mist is alpha-blended and may sort imperfectly in some engines. glb-lint reports 0 errors; its warnings are the deliberately raised triangle, material and draw-call budgets (declared as overrides in the plan) and the diorama's scale.
