Origin is the underside of the projector body, so place it with the plate at your ceiling: for a 3.2 m ceiling, place the model at y=2.81. The mains and signal leads are not modelled and the lens is glass, not a light source. 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-ceiling-projector-m-3875de72","cdnUrl":"https://cdn.3dassets.dev/assets/34742/v1/model.glb","downloadUrl":"https://3dassets.dev/download/university-lecture-hall-and-campus-ceiling-projector-m-3875de72","thumbnailUrl":"https://cdn.3dassets.dev/assets/34742/v1/thumb.webp","posterUrl":"https://cdn.3dassets.dev/assets/34742/v1/poster.webp","blurhash":"UDEMLCD*00%MD%xaNGNG00jY%Nxu~pIooL%L","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":45792,"triangles":1024,"vertices":2187,"meshes":5,"materials":5,"textures":0,"animations":[],"boundingBox":{"min":[-0.20000000298023224,0.000005950736907470167,-0.18799999356269836],"max":[0.20000000298023224,0.38999999314546585,0.2680000066757202]},"sizeMeters":[0.4,0.39,0.456],"hasDraco":false,"hasMeshopt":false,"hasKTX2":false,"extensionsUsed":["KHR_mesh_quantization"]},"aiGenerated":true,"aiModel":"Claude Opus 5","downloads":0,"publishedAt":"2026-09-11T10:10:34.685Z","updatedAt":"2026-09-11T10:10:34.800Z","usage":{"threejs":"import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js'\n\nconst loader = new GLTFLoader()\nloader.load('https://cdn.3dassets.dev/assets/34742/v1/model.glb', (gltf) => {\n  scene.add(gltf.scene)\n})","r3f":"import { useGLTF } from '@react-three/drei'\n\nexport function LectureTheatreCeilingProjectorOnADropMountUniversityLectureHallAndCampus(props) {\n  const { scene } = useGLTF('https://cdn.3dassets.dev/assets/34742/v1/model.glb')\n  return <primitive object={scene} {...props} />\n}\nuseGLTF.preload('https://cdn.3dassets.dev/assets/34742/v1/model.glb')","modelViewer":"<model-viewer src=\"https://cdn.3dassets.dev/assets/34742/v1/model.glb\" alt=\"Lecture Theatre Ceiling Projector on a Drop Mount (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/34742/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/34742/v1/model.glb\")) await gltf.InstantiateMainSceneAsync(transform);"}}}
