The core difference
| 3D Product Viewer | 3D Product Configurator | |
|---|---|---|
| Main task | Inspect a product | Build or compare a configuration |
| Product state | Usually fixed | Changes with selections |
| User action | Rotate, zoom, inspect | Select options and see the result |
| Best fit | One main product form | Products with meaningful variants |
When is a viewer enough?
Choose a viewer when the product has few or no variants, the goal is to inspect shape and details, photography cannot show every angle, or the experience is mainly a product showcase.
When does a configurator make more sense?
A configurator is more appropriate when different selections change the product, buyers need to compare combinations, or materials, finishes, dimensions, components, or accessories affect the final appearance.
Can a viewer become a configurator?
Yes, but scope changes. A configurator adds an option model, valid-combination rules, visual states, selection UI, and sometimes structured output.
The decision rule
If the question is “What does this product look like?”, a viewer may be enough. If the question is “What will this product look like with these options?”, a configurator is the stronger fit. See What Is a 3D Product Configurator? and INTR's 3D Product Configurator service.
