At its core, 3D scanning is the process of capturing the physical shape and texture of an object or environment with high precision. Using specialized scanners like lidar, photogrammetry rigs, or structured Camera & Lighting systems professionals generate detailed digital models that can be integrated into computer-generated imagery (CGI). These digital assets are often used in post-production to blend real-world elements with computer-generated content, enhancing realism and narrative possibilities.
