What are the Observer "assumptions" that are included in RS2?

The primary assumptions are taken from how we view the external world. Imagine you are carrying a camera... what are the components involved with getting the "outside" into your brain?

  • The "camera" -- what is detecting the image (your eyes are also a "camera" on the world)
  • The focal/projective plane, which determines what you see clearly.
  • The type of lens used (orthographic, projective, stereoscopic, fisheye)
  • The environment that determines what is "coordinate" through its geometry (in RS2, "space" is rectilinear and "time" is polar).
  • The object under observation, with all its structure (rotations, locations, etc).

The concepts can be summarized by this figure:
