Artificial Intelligence and 3D
12:00PM - 12:30PM PDT
Presenter: Gordon Au
Many modern developments in AI deal with the 3rd dimension, from self-driving cars that perceive and navigate their environments in 3D, to programs that can build 3D models of scenes simply by analyzing 2D videos of them. Though some of these AIs are only accessible to researchers and tech companies, some AI applications like upscaling images or colorizing black and white photos are immediately useful and available to all. This workshop will show you how to use AIs of special interest to stereographers, via the free tool Google Colab, to do things like: create depth maps and stereopairs from single images, change the depth of stereopairs, and create videos and stereovideos.Workshop notes (external page- goes live Sunday August 15th)

Based in Brooklyn, New York, Dave is a stereographer, hacker, reverse engineer, and futurist. He grew up with a fascination for View-Masters, and rediscovered 3D in 2001 when he realized in a dream that digital stereo video was easily achievable. In 2010 his contributions led to Star Wars Uncut winning an Emmy award (scene 458/473!) Currently he is Secretary of the New York Stereoscopic Association, and probes the digital beyond through experimentation in Virtual Reality, XR, photogrammetry, and brain hacking.
When Steve was in the second grade, he found a book on his grandfather’s bookshelf called '101 Things Any Boy Can Make' that had a chapter on learning how to free view stereo cards and how to draw them. He was fascinated by the examples in the book and learned to draw his own cards. It turned into a lifelong interest. When he found out about the existence of other people who shared his interests, he joined the NSA and became active in the organization giving workshops and participating in competitions.Over the years he has produced all forms of 3D, often manufacturing his own 3D equipment, but his first love remains making stereo cards.
Hi. My name is Barry Rothstein, and I'm known to be "the phantogram guy." I saw my first phantograms at the 2004 NSA convention in Portland, Oregon. Steve Hughes exhibited a couple and provided the NSA's first phantogram workshop. Terry Wilson showed and sold her line of phantogram note cards, beautiful flower images, and a mushroom phantogram I bought.
Like all of you I fell in love with 3-D. I'm especially fascinated by phantograms.
A phantogram is an attempt to visually re-create reality, to imitate normal vision. It's key component is in the way the images are cropped to reverse the effects of perspective. Given a point of view and a precisely defined stereo window, I strive to give the eyes what they'd get in real life.A phantogram is most typically viewed from an angle and not straight on. It's shot at an angle relative to a reference frame (stereo window). Some people claim they always should be shot from a 45 degree angle. Owen Western calls them "phantoglyphs" and shoots from 30 degrees. I choose to shot them from practically any angle, mostly looking for a visual moment I find pleasing to my eyes.
Jim Swallow is a professional photographer in St Petersburg Florida with over 40 years of professional experience. He has been creating stereo images for the past 12 years and more seriously for the past 4 years. Jim has worked in Photoshop for the past 25 years. The techniques he will share are simple and easy and can turn an ordinary image into a more interesting image in mere minutes. Creating a compelling 3D photograph is about having elements in the foreground, mid-ground and background, but is also about light and shadow. Jim is going to show you how to add light and shadow to images to aid in the 3d experience.
Greg Perez has been photographing in stereo since the early 80's and has recently taken up VR. He is a long time member of NSA and the Puget Sound Stereo Camera Club. He is now retired and living near Wichita Kansas. He is currently co-chair of 3D-Con 2022.
Gordon is an avid stereographer and 3D experimenter/tinkerer, making stereophotos, stereovideos, anaglyphs, extractions, and conversions, drawing upon a variety of sources, including TV and film, artwork, NASA data, found footage, and more. His experiments include catadioptric stereos, artificial intelligence, slices and shapes, asymmetric framing, video panning / zooming of 3D stills, x‑rays and fog as depth map sources, and more. Gordon is a proud member of and have presented and/or written for the NSA, ISU, New York Stereoscopic Association, Virtual Stereoscopic Community, and LA3D Club.
Dr. Guenter Pomaska worked for many years in the fields of photogrammetry and application software development and support. He was teaching computer graphics and related topics in higher education institutes. After retirement he became a member of DGS and ISU and directed his activities into special applications of stereoscopy.
