3D Scanning

Definition

3D scanning is the process of capturing the physical shape and appearance of a real-world object or environment and converting it into a digital 3D model. This technique uses various technologies, such as laser scanners and structured light, to create detailed representations that can be utilized in virtual production and CGI integration for films and video games. It allows for realistic textures, intricate details, and accurate dimensions, making it invaluable in creating immersive digital experiences.
