33 PFN 3D Scan 3D scanning service Launched in June 2022, PFN 3D Scan allows users to create 3D models that are faithful in appearance to the actual objects. PFN 3D Scan takes advantage of a deep learning technique that reconstructs free-perspective 3D graphics from 2D photographs taken from multiple angles. The PFN 3D Scan system can reconstruct transparent, metallic or black objects which were previously hard to 3D-scan. PFN has scanned nearly 30,000 objects for use in virtual reality, e-commerce and more. Problems to solve ● Time and effort for building 3D models ● Difficulty to 3D-scan transparent, metallic and black objects https://youtu.be/RX4j6wxWev8 Details: https://pfn3d.com/ Objects scanned using PFN 3D Scan Solutions and Products Creative
