History of
• First anaglyph stereoscopy movie was in 1915 by Edwin S Porter
• First Polarization picture was in 1936 when Edwin H. Land applied this technique.

Anaglyph red/cyan illusion• Definition: Wikipedia - the name given to the stereoscopic 3D
effect achieved by means of encoding each eye's image using filters of different (usually chromatically opposite) colors, typically red and cyan
• Wait a minute, WHAT IS STEREOSCOPIC? Here we go!refers to a technique for creating or enhancing the
illusion of depth in an image by presenting two offset images separately to the left and right eye of the viewer

Possible color schemes; Patents and egos made filter colours rather confusing.

RGB, red, green, blue.But what is Red/Cyan• The red color is well, 255,0,0, and Cyan is 0,255,255

Other types of illusions?• Polarized? Wiki; create the illusion of three-dimensional images
by restricting the light that reaches each eye, an example of stereoscopy which exploits the polarization of light
• Passive requires that each eye sees only half the pixels on screen, the picture's resolution is effectively halved
• shutter glasses (active) enables rich stereoscopy without reducing the number of pixels and lights, but gets people sick!
• 2 types1) Passive = No movement in the left and right lenses, the
orientation of the oscillation of the light waves.2) Active = Movement in the lenses (opening and closing)
for the left and right in synchronization with the picture.

viewing without glasses• The holy Grail is 3D viewing without glasses
Recently Toshiba has launched a 3D TV without the need for glasses.
• Then we have 3D Holographic TV Technology or 3D Hologram TV
• They say in another 10 years it should be available widely.

How is Anaglyph created?
• A few ways.– 1
• take a photo of a object then move the camera over 3” and take the same picture. 3” is about the distance between our eyes.
– 2 • Mount cameras side by side shooting video or pictures, GoPro HD
example.
![Page 14: Driving a game engine with Revit in the backseat, on a 3D stereoscopic highway Kirk Bricker GTG Architects](https://reader038.vdocuments.net/reader038/viewer/2022110207/56649d8b5503460f94a72071/html5/thumbnails/14.jpg)
Well Gosh….Revit has cameras!• Why not create 2 cameras in Revit 3” apart and shoot them at a
object?• Place the subject/object in a setting with a lot of angles and
depth (not in front of a flat wall), and about 10 to 15 feet from the camera. Make sure your subject stays very still, yep Revit will stay still.

Game Engine stereoscopic ?
• What is it? In a nut shell, it’s a rendering engine. With lots of added bells and whistles to enhance the user experience.
• 2D or 3D graphics• Physics engine• Collision detection• Sound• Scripting – Java, C#, C++• Animations• Artificial Intelligent• Networking• Memory management• Shaders

Unity3D
• First off we need to get the Revit model into a collada file or a .fbx
• .fbx export is not separating the .fbm file Revit 2011? which is the material info, BAD!
• Use a Collada .dea exporter from an add-in from http://www.lumion3d.com
• Unity has a live data base Import, meaning as soon as you paste a file into the folder structure it loads into Unity3D even when running Unity3D.
