3D Scanning has become an essential tool in the VFX industry. It is used to create digital assets, which can be used in computer-generated imagery and other post-production processes. This article will discuss the basics of 3D Scanning and its uses in the VFX industry.
What is 3D Scanning?
3D Scanning is the process of capturing the physical geometry of an object or environment. The result is a digital 3D scan model, which can be used in various ways. There are different methods of 3D Scanning, but all of them involve the use of special equipment such as laser scanners, photogrammetry, structured light scanners, or CT scanners.
Uses of 3D Scanning in the VFX Industry
In the VFX industry, 3D Scanning is used to create digital assets for films, TV shows, and video games. These digital assets can be anything from characters and props to entire environments. In addition, the 3D digital models created through Scanning can be used in various VFX processes, such as compositing, match moving, and animation.
Character and Prop Scanning
One of the most common uses of 3D Scanning in the VFX industry is the creation of digital doubles for actors. A digital double is a 3D model of an actor’s body, which is used in place of the actor for certain shots. 3D Scanning is also used to create digital models of props, such as weapons or vehicles, which can be used in post-production.
Environment Scanning
3D Scanning also creates digital models of environments, such as buildings or cityscapes. These digital models can be used in various ways, for previsualization or compositing. For example, a digital model of a city could be used to add buildings or other elements to a shot.
Match Moving
Match moving is the process of tracking the movement of a camera in a live-action shot. This information can then be used to composite CGI elements into the image, making them appear as part of the scene. 3D Scanning creates digital models of the physical environment, which can be used for match moving.
Animation
3D Scanning is also used in animation to create digital models of characters and objects. These models can be used to create realistic animations, as the digital model’s movement will mimic the physical object’s movement.
Final Words
3D Scanning is an essential tool in the VFX industry, allowing digital assets to be created in various post-production processes. For example, it is used to create digital models of characters, props, and environments, which can be used in compositing, match moving, and animation.
As technology continues to improve, we expect to see more uses for 3D Scanning in the VFX industry.
