Modelled with the bottom of the fabric on y=0, so mount the whole model at the drop height you want; the cassette top sits 2.15 m above it. The fabric is a rigid sheet and does not roll: a retracting screen is a deforming surface, which a rigid node transform cannot do. Metre units, +Y up, the user side toward +Z, resting on y=0. Static geometry; no rig, collision or navigation data.","status":"published","url":"https://3dassets.dev/assets/university-lecture-hall-and-campus-projection-screen-f41396d5","cdnUrl":"https://cdn.3dassets.dev/assets/34739/v1/model.glb","downloadUrl":"https://3dassets.dev/download/university-lecture-hall-and-campus-projection-screen-f41396d5","thumbnailUrl":"https://cdn.3dassets.dev/assets/34739/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/34739/v1/poster.webp","blurhash":"UIFPKc%M00WBR*-;xuD%00Rj~qxbt7RkRj%M","category":{"slug":"buildings","title":"Buildings & Architecture"},"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":24368,"triangles":512,"vertices":1151,"meshes":3,"materials":3,"textures":0,"animations":[],"boundingBox":{"min":[-1.784999966621399,0.00007220607843372306,-0.08997009200444081],"max":[1.784999966621399,2.149927889288998,0.06997008872618535]},"sizeMeters":[3.57,2.15,0.16],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"Claude Opus 5","downloads":0,"publishedAt":"2026-09-11T10:10:32.795Z","updatedAt":"2026-09-11T10:10:32.897Z","usage":{"threejs":"import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js'\n\nconst loader = new GLTFLoader()\nloader.load('https://cdn.3dassets.dev/assets/34739/v1/model.glb', (gltf) => {\n  scene.add(gltf.scene)\n})","r3f":"import { useGLTF } from '@react-three/drei'\n\nexport function LectureTheatreProjectionScreenUniversityLectureHallAndCampus(props) {\n  const { scene } = useGLTF('https://cdn.3dassets.dev/assets/34739/v1/model.glb')\n  return <primitive object={scene} {...props} />\n}\nuseGLTF.preload('https://cdn.3dassets.dev/assets/34739/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/34739/v1/model.glb\" alt=\"Lecture Theatre Projection Screen (University Lecture Hall and Campus)\" 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/34739/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/34739/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);"}}}
