Previsualization: History and Key Facts

Previsualization (also known as previsualisation, previs, previz, pre-rendering, preview, or wireframe windows) is the process of visualizing scenes, sequences, or environments before their physical production. Originally associated with film, where it is used to plan camera angles, staging, and visual effects before shooting, the practice has expanded into other creative disciplines including animation, live performance, concerts, theater, video game design, and still photography. Techniques range from traditional storyboarding with hand-drawn sketches to digitally assisted 3D simulations that allow directors and designers to explore timing, spatial composition, and technical feasibility in advance.
