P3D Re: The Imagination Effect

["Oleg Vorobyoff" <olegv@xxxxxxxxxxxxx>]

I experienced a similar effect first time last year and found it too
real and stunning to be completely "imagined."  I think each eye
selectively concentrates on different parts of the image sufficiently
to trigger 3D perception.  In this respect I'd say it is stereoscopic.
Sort of like perceiving the notes of a an arpeggio as a chord, except
that the necessary cues are strung out in a 2D field instead of time.
The effect happened to me after an evening of staring at stereograms.
I think the training partly involves decoupling oneís facility of
focusing from that of depth perception.
