Pre-visualization is a process in pre-production where complex scenes can be staged and planned out before shooting begins. It began with the use of storyboards for specific framing and art direction. More effects driven sequences use pre-visualization to create a detailed blueprint of the scene. With 3D technology, pre-visualization can imitate camera movement and blocking within a virtual space, recording camera data to use for the production and visual effects artists later down the line. Pre-visualization is an important tool of communication for the director, who must convince producers and maintain an overall vision throughout production.
