[photo-3d] Stereoscopic Displays and Applications XII Last Day

I thought I posted this already but I guess not.

Stereoscopic Displays and Applications XII Last Day

The last day of this part of the conference started with a session on
the problems of compressing stereoscopic images for use in the
Internet.  The AM presentations dealt with multi-view and 2-image
stereo.   This was also the day with the most Photo-3ders present,
Including Lawrence Haines, Lawrence Kaufman, Michael Georgeoff, David
Lee, John Toeppan and the previously mentioned John Rupkalvis and Andrew
Woods.

Later the keynote speaker, Jeff Kleiser, of Kleiser-Walczak Construction
Company spoke of work they have done in several productions.  Kleiser
has worked on the Phillip Glass/Robert Wilson production “Monsters of
Grace”.  He showed a several minute documentary on the making of the
Opera.  The opera was produced with a 3D background because the original
plans for the set design involved a giant foot in the background.
Rather than truck around a giant foot for the productions they felt it
would be more expedite to produce a stereo image of the foot.  Later
they decided that the backgrounds for the rest of the opera could be
done using the stereo method.  They used 70mm film because of the
resolution needed.  Due to the slow movement of the backgrounds and
Wilson’s feeling that extensive texturing was not needed for the effect
he wanted to produce, photo-realistic images were not attempted.  Later
he showed slides of the images in the opera, most were “behind the
stereo window” because of the needs of the set designer.  Several images
were brought in front of the window but these were rare.

Later he showed the work that went into the production of Universal’s
the Adventures of Spiderman Ride”.  This ride mixed 3d projection with
sensory effects (spraying water, wind…) and props.  It is a moving
(mobile) ride that attempts to put the rider in the midst of a cartoon.
He went over the extensive testing that was done in deciding where in 3d
space (how far through the stereo window) some objects would have to
go.  They did this by ‘pulling people off the street’ because over time
most of the people who worked on the graphics would increase their
accommodation of stereo images and tolerate more separation than most
people.

He also demonstrated some of their non-3d work.  These include some
special effects for the feature length movie X-Men (which they are in
the running to be nominated for an Academy Award) and a children’s book
adapted into a short cartoon.

Demonstration Session

After the Keynote presentation, the much anticipated demonstration
session took place.  This included autostereoscopic, active, and passive
3d displays.  Unfortunately, I believe, none of the people who presented
at the Autostereoscopic presentation the day before had demonstrations
available.  So goes the proof is in the pudding expression.  Some of
them mentioned having displays available at Comdex but nothing presented
was shown here.  This is not to say that there were no autostereo
displays shown however.  There were some that were not presented at this
conference (see below)

Passive 3D Displays

John Rupkalvis of StereoScope International showed a simple but elegant
viewer for a two video camera 3D system that employed mirrors, TV
monitors and linear polarizers.  This allowed for the viewer to use
conventional polarized glasses to view the resultant 3D in a mirrored
viewing box in real time.

StereoJet had their display of StereoJet prints available for viewing.
Significantly the price for these has been recently reduced and are now
realistically in the range of most stereographers ($50 for an 8 x 10”
print).

Dynamic Digital Depth had examples of their streaming video content
(aimed at internet users) in anaglyphic format.

Active 3D Displays

I-O had their shutter glasses, camcorder attachment and new 3d titles.
These included some Mark Blum titles and Sports Illustrated Swimsuit in
interlaced 3D.

Shown for one of the first times in the US was the dedicated 3D
attachment made by Canon for its XL-1 prosumer camera. It is an
interchangeable compact zoom lens for the XL1 digital video camcorder
that enables the recording of three-dimensional images.  The 3D zoom
lens also incorporates a focusing unit that uses triangulation to
measure the distance to the subject and a motor to adjust the mirrors
inside the left and right lenses accordingly, enabling the angle of
convergence to be set automatically They believe the lens will retail
for about $6500 (The camera is $4,000 with a 2D lens, $3,000 with no
lens).  It should be available this year.

VREX was present and showing some of its new shutter glasses.  Rumor is
that a new version of Depth Charge will be available and later a new
DepthCharge Developer Studio.

Autostereo
Several autostereo systems were shown but were the basic lenticular
systems that have been seen before.  However, this did not detract form
their attractiveness.  Dimension Technologies of Rochester NY had a nice
lenticular display along with a slide show.  It had an LED that would go
off when you were in the correct position to see 3d.

Microscope Attachments
Two companies were present showing their microscope accessories for
viewing three-dimensionally through a microscope.

Edge had its Microscope Accessories for Direct-View 3D Imaging.  They
used a special light source to allow for stereo viewing using oblique
and dual oblique imaging

Digital Optical Technologies presented their microscope that provided
for optical conversion of mono-path high magnification microscopy to
dual-path stereoscopic video microscopy.  They have partnered with
Isee3d, Leica and DTI to integrate the technologies involved.
