Overall 0.60 by 0.79 by 0.08 m (X by Y by Z). Metre units, +Y up, the side a customer or a patient approaches from toward +Z, resting on y=0. The blocks are abstract rectangles, never letters: nothing in this pack is readable. The panel rests on y=0, so place it at the height the wall needs, about 1.2 m to the bottom edge for a seated patient. Static geometry; no rig, collision or navigation data.","status":"published","url":"https://3dassets.dev/assets/opticians-and-eyewear-showroom-test-chart-60de2929","cdnUrl":"https://cdn.3dassets.dev/assets/35065/v1/model.glb","downloadUrl":"https://3dassets.dev/download/opticians-and-eyewear-showroom-test-chart-60de2929","thumbnailUrl":"https://cdn.3dassets.dev/assets/35065/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/35065/v1/poster.webp","blurhash":"UFD,7h-;004n%NxuRPIU00M{~qxuxuj[M{WB","category":{"slug":"props","title":"Props & Furniture"},"tags":[{"slug":"modern","title":"Modern"},{"slug":"realistic","title":"Realistic"},{"slug":"interior","title":"Interior"}],"license":{"slug":"cc0-1.0","name":"CC0 1.0 Universal","url":"https://creativecommons.org/publicdomain/zero/1.0/","attributionRequired":false},"contributor":{"username":"3dassets","name":"3D Assets","url":"https://3dassets.dev/u/3dassets"},"stats":{"fileSize":13240,"triangles":240,"vertices":560,"meshes":3,"materials":3,"textures":0,"animations":[],"boundingBox":{"min":[-0.30000001192092896,0,-0.04497905846017922],"max":[0.30000001192092896,0.7900129868576611,0.0320187842075159]},"sizeMeters":[0.6,0.79,0.077],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"Claude Opus 5","downloads":0,"publishedAt":"2026-09-11T11:15:39.203Z","updatedAt":"2026-09-11T11:15:39.309Z","usage":{"threejs":"import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js'\n\nconst loader = new GLTFLoader()\nloader.load('https://cdn.3dassets.dev/assets/35065/v1/model.glb', (gltf) => {\n  scene.add(gltf.scene)\n})","r3f":"import { useGLTF } from '@react-three/drei'\n\nexport function TestChartOpticiansAndEyewearShowroom(props) {\n  const { scene } = useGLTF('https://cdn.3dassets.dev/assets/35065/v1/model.glb')\n  return <primitive object={scene} {...props} />\n}\nuseGLTF.preload('https://cdn.3dassets.dev/assets/35065/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/35065/v1/model.glb\" alt=\"Test Chart (Opticians and Eyewear Showroom)\" camera-controls auto-rotate></model-viewer>","blender":"# Blender 4.x: File > Import > glTF 2.0, or from the Python console after downloading the file.\nimport bpy\nbpy.ops.import_scene.gltf(filepath='model.glb')  # from https://cdn.3dassets.dev/assets/35065/v1/model.glb\n# Metres and +Y up are converted to Blender's Z-up scene automatically.","godot":"# Godot 4: copy model.glb into res://models/ and the editor imports it as a scene.\nvar packed := load(\"res://models/model.glb\") as PackedScene\nvar model := packed.instantiate()\nadd_child(model)","unity":"// Unity: import model.glb with glTFast (Package Manager: com.unity.cloud.gltfast) and drag the prefab in,\n// or load it at runtime straight from the CDN:\nusing GLTFast;\nvar gltf = new GltfImport();\nif (await gltf.Load(\"https://cdn.3dassets.dev/assets/35065/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);"}}}
