3D modeling technology began in the 1960s with wireframe models on computers and evolved through major milestones including polygon-based graphics in the 1980s, real-time 3D rendering in the 1990s, and modern GPU-accelerated tools in the 2000s. Today, 3D modeling is used in film, games, engineering, medicine, and architecture.
