[photo-3d] Re: The "wobble" effect

[Ron Beck <rbeck@xxxxxxxx>]

I wonder if there's an "optimum" wobble speed.  Would a faster wobble
speed give better depth perception?  Would a slower speed negate the 3D
appearance?

Obivously when we see a static 2D object, such as the snowflake below,
we have some perception of depth based on our knowledge of the world. 
It appears that the wobbling image provides us with additional depth
queues.  Thus, we perceive an additional depth to the image that we
couldn't do with a static image.

Now, can anyone do this with one of their stereo images?  If I can find
my gif animation software, I may try it.

Regards,
Ron
