A system for viewing and tracking stereoscopic video images in a dental setting, comprising:
- a first video camera configured to generate a first video feed of a patient's intraoral cavity, and
- a second video camera spaced at a pupilary distance from the first video camera and configured to generate a second video feed of the patient's intraoral cavity,
the head mountable stereoscopic display a head mountable stereoscopic display including
- a right video display and a left video display to create a near real-time stereoscopic video image from the first video feed and the second video feed, respectively,
- tracking module associated with the first video camera and the second video camera, the tracking module configured to cause the first video camera and the second video camera to be directed to a desired convergent point relative to a selected tracking point to maintain stereopsis as movement occurs for at least one of the patient's intraoral cavity, the first video camera, and the second video camera, and
- zooming module associated with the first video camera and the second video camera, the zooming module configured to provide a desired magnification of the near real-time stereoscopic video image.

A method for navigating a three dimensional (3D) stereoscopic scene displayed via a 3D stereoscopic display system the method comprising:
- enabling a user head tracking navigational mode of the 3D stereoscopic display system,
- establishing a reference point of view (POV), and
- tracking user head POV,
wherein the reference POV comprises
a reference user head position and a reference user head orientation,
wherein
- said adjusting is based on a non-linear mapping between changes in the camera POV and the user head positional displacements and user head angular rotations relative to the reference POV,
- said tracking monitors user head positional displacements and user head angular rotations relative to the reference POV,
- adjusting, in response to said tracking, a camera POV used to render the 3D stereoscopic scene,
- mapping of user head positional displacements relative to the reference POV to translational movements in the camera POV, and
- mapping of user head angular rotations relative to the reference POV to rotations in the camera POV,
wherein the non-linear mapping comprises:
