Hello! One of our faculty members would like to display a series of stereoptic images on a pair of projectors attached to a Macintosh. (His original reason for contacting me was to inquire about how to attach two displays to a single Macintosh, never dreaming that this would be the simplest part of the matter.) So now I'm looking for an application to display a series of stereoptic images. A sort of "stereo PowerPoint" (if you will.) Denis Pelli suggested that perhas someone on this forum had done something like this using the psychotoolbox. Thanks in advance for any assistance... ---

In the OpenGL Psychtoolbox, the demo "StereoDemo" would be a starting point for such a thing ("help StereoDemo"). In PTB, you can pass the optional 'stereomode' parameter to Screen('OpenWindow') to select a method of stereo presentation, then use the Screen('SelectStereoDrawBuffer') command to choose if following drawing commands should draw the left-eye stim or the right-eye stim. E.g., in extended desktop mode (two displays/projectors form a double-width, single desktop), mode 4 would do the job for you, whereas mode 1 is great for stereo goggles (shutter glasses) and modes 6 to 9 are useful for anaglyph stereo. -mario > --- In [psychtoolbox@yahoogroups.com](mailto:psychtoolbox@yahoogroups.com), "JoeSUNY" \ wrote: > \> > \> Hello! > \> > \> One of our faculty members would like to display a series of > \> stereoptic images on a pair of projectors attached to a Macintosh. > \> (His original reason for contacting me was to inquire about how to > \> attach two displays to a single Macintosh, never dreaming that this > \> would be the simplest part of the matter.) > \> > \> So now I'm looking for an application to display a series of > \> stereoptic images.
