3D Structure & Materials

This document explains the technical structure (Mesh, Material, Slot) of how items are composed on R.Design. This knowledge is necessary when brand representatives register products or perform advanced customization.

Mesh & Material

Items on R.Design are expressed by a combination of Mesh (shape data) and Material (surface texture data).

Mesh

3D data that defines the “shape” of an object. It is composed of a collection of polygons. For example, the Mesh of a coffee table holds only the shape information of the top board and legs, and does not hold color or texture information.

Material

Data that defines the “texture” of an object. It includes information such as color, gloss, reflectance, and bumps (normal map). By applying Material to Mesh, it is displayed as realistic furniture for the first time.

State where Material is applied to Mesh

Material Slots

There is a mechanism called Material Slot to apply multiple Materials to a single Mesh.

• Slot: Definition of the “place” to assign Material on the Mesh.
• For example, if a chair Mesh defines two slots, “Seat” and “Legs”, you can apply different Materials to each (Fabric for the seat, Wood for the legs, etc.).
