What is the Projection View Matrix in Spatial Computing
The area within the point of view of a camera that is visible in an augmented reality (A/R), virtual reality (V/R), mixed reality (M/R) or spatial computing experience.

When creating an A/R, V/R, M/R or Spatial Computing experience some designers or developers question why the camera doesn't visualize things that are either too close or too far.
The reason behind this is that the camera that they have chosen for the experience is configured through two planes, the near plane and the far plane, and only render visuals for the elements of the camera's point of view that fall within the two planes.
The mathematics behind the calculation of this volume is demonstrated below.
