re:Unusual 3d Concept/ Light for Viewer

[P3D sam smith <sam@xxxxxxxxxxx>]

I want to thank  JJ Larrea and Gerald Siegel in helping me understand one of
the more complicated 3d concepts I've encountered. I have a copy of " Three
Dimensional Projection " hidden in storage somewhere, I'll have to dig it
out and read the part on Francois Savoye.
I'm still working on my 2 1/4 stereo viewer and have not found the perfect
light source and transluscent material for it.  I tried 6 volt halogens, but
their too dim. If I switch to 120v source, I'd have to use a large dimmer to
control intensity instead of just a potentiometer. Thinner transluscent
material gives me hot spots around the bulbs.
Has anyone tried using fresnels ?
The rest of the viewer functions fine, I've made a slide carrier that
functions like a toaster, feeding from the top. The viewer raises from it's
base to change the viewing angle. If anyone is interested in a copy of my
drawing plan, I'd be happy to email them one.

Sam
