Load and View Models
Drag and drop GLB/GLTF files or load from a URL. The viewer handles complex geometries, multiple meshes, and embedded textures. Models render instantly with orbit controls for rotation, pan, and zoom.
GLB 3D Model Viewer
Most CAD tools export GLB/GLTF files, but reviewing them usually requires installing heavy software. This viewer runs entirely in the browser: drag a file, inspect the geometry, adjust the view, and share the result. No plugins, no accounts, no downloads. #GLBViewer #3DModels #CADVisualization
Open GLB ViewerWhat You Can Do
Inspect Geometry
Toggle wireframe overlay to see mesh topology. View model bounding box dimensions. Examine how your CAD export translates to triangle meshes, useful for 3D printing and FEA mesh quality checks.
Control Lighting and Environment
Adjust ambient and directional lighting to reveal surface details. Change background color. Rotate the light source to check for surface defects, draft angles, and fillet quality on injection-molded parts.
Share and Export
Take screenshots of specific views. Share the viewer link with colleagues for collaborative design reviews without requiring CAD licenses.
Supported Formats
| Format | Extension | Description |
|---|---|---|
| GLB | .glb | Binary GL Transmission Format. Single file containing geometry, textures, and animations. Most compact format for web delivery. |
| GLTF | .gltf | JSON-based GL Transmission Format. Human-readable structure with external texture references. Standard export from FreeCAD, Blender, and SolidWorks. |
Both formats are part of the glTF 2.0 specification maintained by the Khronos Group. FreeCAD, Blender, Fusion 360, SolidWorks, and most modern CAD tools support direct GLB/GLTF export.
Use Cases
-
Design Review Export your FreeCAD or Blender model as GLB. Open in the viewer and rotate to check clearances, draft angles, and assembly fit. No need to install CAD software on the review machine.
-
3D Print Pre-Check Toggle wireframe to inspect mesh quality before sending to a slicer. Check for non-manifold edges, missing faces, or overly dense tessellation that could cause print failures.
-
Student Submissions Students in the Parametric CAD and Code-Based Mechanical Design courses can export their assignments as GLB and verify geometry before submission.
-
Documentation Capture specific view angles as screenshots for technical reports, assembly instructions, or patent illustrations.
