The camera command sets mono or stereo viewing and related
parameters. If given without arguments, it reports the current settings
in the Log, including position and view direction.
The camera mode can be:
The fieldOfView option specifies the horizontal
angular field of view (default 30°) for all modes
except 360° and orthographic.
The previous field-of-view angle is not remembered through uses of
orthographic or any 360° mode and the value will revert to 30°
upon switching from one of those modes to a relevant mode.
- mono (default) - monoscopic with perspective
(apparent size decreasing with distance from the viewer)
- ortho - orthographic, monoscopic without perspective
- stereo - sequential stereoscopic; see also the
--stereo startup option
- sbs - stereoscopic side-by-side layout (walleye)
- tb - stereoscopic top-bottom layout
- 360 - 360° monoscopic
- 360sbs - 360° stereoscopic side-by-side layout
- 360tb - 360° stereoscopic top-bottom layout
The eyeSeparation option specifies the distance between
left- and right-eye viewpoints in scene distance units,
usually Å, for all stereo modes
(default 0.2 for 360° modes, otherwise 5.0).
The pixelEyeSeparation option specifies the distance between
left- and right-eye viewpoints in screen pixels (default 200)
for sequential stereo.
This is usually determined adequately by the display, but adjustments
may be needed for comfortable viewing when sequential stereo is projected.
