 Note: Typically when constructing a perspective projection matrix for rendering the developer specifies the viewing frustum and the near and far clip planes. When displaying to an [=immersive XR device=] the correct viewing frustum is determined by some combination of the optics, displays, and cameras being used. The near and far clip planes, however, may be modified by the application since the appropriate values depend on the type of content being rendered.
