Hi All,

I can see that I have to respond to this and clarify things. If you will
carefully read my original posting, I fully acknowledged the true 3D nature
of space in a computer modeled environment. I have used TrusSpace myself to
create stereo pairs and I like the program and what it does. 

What I was poking fun at was the deliberate choice on the part of 80%+++ of
the users of such programs like TrueSpace, to only create one image of a
given scene from their complex 3D environment and label that single 2D image
as "3D". 

It is so easy to take both a left and right image when such an environment
has been created, yet most don't bother. That's OK, but it's totally
eronneous to claim that the resulting 2D images are actually 3D. They are
equivalent to ordinary snapshots from ordinary real world 3D reality. This
is a disturbing popular trend throughout the computer industry. I chalk it
up to "overexcitement" with having the relatively new 3D environment to work
and play in along with widespread ignorance of the error. Maybe when stereo
viewing systems become more prevalent and less expensive the terminology can
be used more accurately?. Or maybe those who are knowledgable can make the
distinction better known?

I know about all the other depth cues other than "stereo" imaging. A stereo
pair format still allows all these cues plus stereo disparity for a complete
3D effect not possible without separate images provided to each eye. I will
point out that in traditional art, such efforts to present all possible
depth cues still don't qualify the images as 3D, even though we often
comment on how "realistic" or "3D" they may appear. Those same cues are easy
to accomplish with a program like TrueSpace because it is a true 3D
environment and allows you to position multiple cameras and lights to get
shading and perspectives that are very accurate. 

With all those advantages and a true 3D environment, why settle for the
Cyclops view of things? It's not true 3D until you take the extra 15 seconds
or so and create the second image. In a computer you don't even have to
worry about wasting film or waiting for processing. (Although rendering can
sometimes be time consuming)
