A 3D configurator enables the user to customize and configure the product according to personal preferences. Various options such as colors, materials, sizes and features can be selected and visualized via the 3D configurator.
A 3D viewer allows the user to view and rotate the product from different perspectives to get a comprehensive idea of it. In contrast, a 3D viewer generally does not offer the option of customizing or configuring the product.
In the world of augmented reality (AR), for example, customers can "project" a 3D model of a sofa into their personal living room and see how it would look there without physically holding the actual piece of furniture in their hands.
