                  StereoCamera

Known Subclasses:
StereoRedBlueCamera, StereoTopBottomCamera

Camera for stereo camera functionality. Initialize with a non-stereo camera.

This class wraps the original (non-stereo) camera instance, passing most method calls through to it. It implicitly creates a second camera for second eye, using a SubordinateEyeCamera and installs that camera in the engine.

The and calc methods maintain the position of this camera and also of the subordinate camera.
Method Summary
  __init__(self, camera, interOc)
Initialize newly constructed camera.
  __getattr__(self, attname)
Delegate most attribute lookups.
  __setattr__(self, attname, val)
Delegate most attribute lookups.
  calc(self)
Recalc position, and pass on to subordinate camera.
  calcEyes(self)
Calculate the two eye pos's.

Method Details

__init__(self, camera, interOc=None)
(Constructor)

Initialize newly constructed camera.
Parameters:
camera - a non-stereo camera instance.
interOc - the distance between the eyes. if omitted, defaults to 1/30th of near distance.
           (type=float)
Overrides:
__builtin__.object.__init__

__getattr__(self, attname)
(Qualification operator)

Delegate most attribute lookups.

__setattr__(self, attname, val)

Delegate most attribute lookups.
Overrides:
__builtin__.object.__setattr__

calc(self)

Recalc position, and pass on to subordinate camera.
Returns:
None

calcEyes(self)

Calculate the two eye pos's.
Returns:
eye tuple (x,y,z), center tuple (x,y,z)
