What is Three-dimensional space in virtual production?

A three-dimensional space is a geometric representation of an object’s position and orientation in 3D, expressed through X-Y-Z coordinates and pitch-roll-yaw. This notion is fundamental to the field of virtual production – it's how we digitally create and manipulate our environment. A number of software packages are available to calculate three-dimensional space. Autodesk Maya and Cinema 4D are just two examples of this type of program that allow us to map out the parameters of an object or scene accurately. 

The importance of three-dimensional space in virtual production cannot be understated: It is the foundation on which all digital animation and effects are built upon. Three-dimensional space allows filmmakers to create worlds that defy physics, such as those seen in films like Avatar (2009) and Avengers: Endgame (2019). In these movies, characters move between dimensions, traverse into alternate realities, and even float off into outer space. 

This kind of impossible imagery was only made possible by using three-dimensional space in combination with motion capture technology. Motion capture artists donned suits equipped with sensors that could track their body movements in real-time, allowing for incredibly realistic animations that had never before been seen. With the help of three-dimensional space, visual effects wizards could transport viewers to surreal places without ever leaving the comfort of the studio.
