Hi I am also interested in stereoscopic images. I have drawn left-eye,right-eye continuous wire drawings on a VT240, using a simple linear-algebra arithmetic package in Ada that I wrote, with my own ReGIS package. I put the left image on the left side ofthe screen and the right eye image on the right side of he screen. I am able to un-cross my eyes to merge the images. the screen. I am able to un-cross my eyes tomerge the images. Why do you need different colors again? I don't understand. The Ada makes everything so simple, I would hate to have to replicate it in Amiga Basic. Tom Janzen Digital Equipment Corporation 111 Locke Marlboro MA is not responsible for what I write. It just owns it. I've taken 3-D photos for years.

I feel obliged to point out the obvious, which is by no means directed at Tom
since I don't know what he means by left image vs. right image.
Stereoscopic images can be viewed by crossing the eyes. They may also be
viewed with a steroscopic viewer. The two (sub)images must be swapped to make
a proper stereoscopic image if you go from one method to the other. Think
about it.
The eye-brain system being the wonderful thing that it is (I don't know where
I'd be without it), if you have the images backwards you still get the very
effective impression of depth. However things are subtly wrong with the
perceived geometry.

Besides, the rest of the "view" becomes blurry or doubled when you do this. Different colors work with filters (red on left eye, blue on right) to seperate the views and produce a much less painful result. LCD shutter glasses are better, as they allow you color. >The Ada makes everything so simple, I would hate to have to replicate it in >Amiga Basic. Suprised to see "Ada" and "simple" in the same sentence :^) Amiga Basic? You've got to be kidding. On the flip side, though, I've resorted to assembler (!) for pure speed. I can rotate a 3D F16 at 16 frames a second. >Tom Janzen Digital Equipment Corporation 111 Locke Marlboro MA is not responsible >for what I write. It just owns it.
