A practical guide to 3D model viewer
3D Viewer loads supported model files into an interactive scene for orbiting, zooming, lighting, and basic model inspection. Geometry, materials, textures, units, and browser GPU limits affect the preview.
Example: inspect a model before handoff
Load the asset, orbit around every side, adjust exposure, check dimensions and materials, and confirm the up axis before conversion.
Task-specific steps
- 1
Choose a supported model and keep its external texture files available when the format references them separately.
- 2
Orbit, pan, zoom, and adjust lighting to inspect surfaces, orientation, scale, missing materials, and clipping.
- 3
Record any issues and open the same asset in the destination application before treating the preview as approval.
Options that affect the result
- Auto-rotation and camera controls expose the model from every side.
- Exposure and viewer details help distinguish lighting problems from missing geometry or materials.
Limitations to know first
- Advanced shaders, animations, rigs, CAD metadata, external textures, and format extensions may not render fully.
- Large meshes and textures can exceed browser memory or GPU limits and make interaction slow.
Questions specific to this task
Why is my 3D model gray?
Material or texture references may be unsupported, missing, or stored in separate files that were not loaded.
Why is the model lying on its side?
Authoring tools use different up axes. Correct orientation before conversion or in the destination scene.
