Stereo

The camera mode refers to any of several stereo and mono viewing options. The camera mode of the Chimera graphics window can be controlled with the Camera tool or the command stereo. The Image camera mode (used for saving image files) can differ from the mode shown in the graphics window.

Available camera modes:

• mono - standard single view
• left-eye - single view from the left-eye position
• right-eye - single view from the right-eye position
• cross-eye stereo - side-by-side views, with the left-eye view on the right and the right-eye view on the left. Currently, there are problems with this mode in the graphics window. To save images in the cross-eye stereo configuration, set the Image camera mode to stereo pair (which will function regardless of the mode shown in the graphics window) rather than using this mode in the graphics window.
• wall-eye stereo - side-by-side views, with the left-eye view on the left and the right-eye view on the right
• red-cyan (anaglyph) stereo - superimposed left-eye and right-eye views tinged in different colors. Glasses with colored filters (such as used to view 3D movies) are needed to produce a three-dimensional effect.
• sequential stereo - rapid flickering between left-eye and right-eye views; special synchronized glasses are needed to produce a three-dimensional effect. Not all systems support this type of display:
  • Sequential stereo is only supported on workstation-class graphics cards with graphics drivers configured for stereo (e.g., ATI FireGL and NVidia Quadro graphics cards for Windows and Linux, NVidia Quadro for Mac OS X).
  • In addition, Chimera for Mac (X Windows) requires a recent update of X11 to show sequential stereo.
  • On some Windows systems, sequential stereo can only be used when --stereo has been specified at Chimera startup.
  • An extra step is needed to display sequential stereo remotely to an SGI.
• VRex row stereo - with rows of pixels alternating between the left-eye and right-eye views
