HDR-ABTF-Scanner

Short Description
The HDR-ABTF-Scanner digitizes optical material behavior of objects (e.g. textiles and leather) faster, easier and more precisely than conventional scanners. It captures texture and light-surface interaction of materials in different lighting situations using an Approximate Bidirectional Texturing Function (ABTF). Moreover, exposure bracketing per direction of incidence represents the object surface in High Dynamic Range (HDR). Users may apply the scanned material when working with programs for true-to-life 3D visualizations, e.g. as part of the design process.

 

Applications
The HDR-ABTF-Scanner captures optical material properties and lighting behavior of flat objects with sizes up to 15 cm x 15 cm. The 3D scanner can be adjusted to objects with a maximum height of 10 cm.
