3D scanning of materials & surfaces - for CGI, e-commerce & AR

UV mapping is the process in which digitized surfaces are projected onto a 3D model. To do this, the 3D model is first "unfolded" (UV unwrapping) and converted into a 2D form. The 2D model is then provided with UV coordinates, which can be compared with X and Y axes. The digital surface texture is now placed on the flat 2D model to assign the texture to specific coordinates. Once the 2D model is converted back to 3D, the 3D artist can simply project the texture onto the model as they now know the exact coordinates.

3D surface scanning is a process in which the physical properties of a surface are digitally captured. To do this, surfaces are captured using 3D scanning methods and digitized as 3D textures. Diеsе technology is vеrwеndеt to еrstеllеn detailed 3D models of objеct surfaces for 3D visualization. PBR textures (Physically Based Rendering) ensure a particularly realistic behaviour of light on digitized surfaces. They are a central component of modern product visualization. CGTrader explains here why realistic 3D textures are indispensable, especially in e-commerce. Preparing material from photos/scans: Adobe Substance 3D Sampler - "Material from image" explains the workflow step by step.

Diеchniqueеn to digitize surfaces as 3D material can vary. 3D scannеn/photogrammеtriе and computеrgеnеriеrtеs Dеsign (computer generated imagery - CGI) are often used. 3D scannеn and photogrammеtriе еrfassеn the physicalеn dеtails еinеr Obеrflächеn and übеrtragеn siеn in еinе digitalе form to create a lifelike digital image. Alternatively, computеrgеnеriеrtеs Dеsign can vеrwеndеt wеrdеt with tools such as 3D shaders to compеxе Tеxturеn and Mustеllеr. Fine micro-relief is created performantly using normal maps instead of real geometry. The digitized 3D textures can then be projected onto the model to make the visualization look realistic. For real heights (joints/embossing), we use displacement maps depending on the use case. For reliable color reference in the capture, we recommend an X-Rite ColorChecker (official site) - reduces deviations during the shoot. If you also want to check whether your textures are tileable, our Tileable Texture Checker will help you.

The duration of the 3D surface digitization process depends on the complexity of the surface, the material, and the technology used. Simple surfaces can be digitized in just a few hours, while complicated surfaces with many details can take up several days.

In the marketing sector, surface digitization helps to present products in a lifelike way without having "real" product photos taken. The digital product images with digitized 3D surfaces can then be used for social media marketing, in advertisements, in online stores or on manufacturer websites.

Our case PBR fabric scan in the furniture project "Wittmann BELETAGE - CGI product images" shows what this looks like in practice.

There are various UV mapping software programs that you can use to project digitized textures onto 3D surfaces. These include, for example, the free UV mapping software Blender or the paid programs Autodesk Maya, Autodesk 3ds Max, Cinema 4D, Unfold3D and Rizom UV.

High resolution surface scans offer extremely high detail accuracy. They are used when you want to create realistic and detailed 3D visualizations, such as in architecture, the automotive industry, product design or advertising. Platforms like Quixel Megascans show how scanned materials can be used in CGI to achieve a realistic representation – e.g. in architecture, the automotive industry or product design.

If you would like to have the surfaces of your product digitized, you can contact our 3D digitization agency Danthree Studio. We not only offer digitizing services but can take care of the entire rendering process for you, from 3D modeling to visualization and rendering. We specialize in the home & living sector such as furniture, interior design, and decorative items. For our CGI surfaces, we can digitize numerous materials in order to optimally represent items made of fabric or steel, wooden, or upholstered furniture in 3D.
