Anaglyph Vision Mode |
|
Anaglyph vision mode is the simple and accessible stereoscopic viewing mode where the superimposed left and right eye views are displayed in different colors. Glasses with a colored filter like the ones used for 3D movies are needed to produce the three-dimensional effect. The red channel is used for the left-eye view, green or blue for the right-eye view. |
|
Auto Stereo Adjust (Auto Correlation) |
|
Adjusting the elevation of the cursor so that the cursor is on the same detail on both left and right images of a stereo model. |
|
Collection |
|
A collection is a collection of models (refer to models). A collection contains data of the same type or project characteristics (same dat, scale, GSD, etc.) |
|
DEM |
|
A digital elevation model (DEM) is a digital representation of ground surface topography or terrain. This is used to obtain the ground elevation (Z coordinate) at a given point. |
|
Hard Drive Cache |
|
Some space on your hard drive is used to load images for faster and seamless viewing. |
|
Image Memory Cache |
|
Some of your system’s memory is used to load images for faster and seamless viewing. |
|
Kappa Correction
|
|
Sometimes one of the two images of a stereo model has a slight rotation. Enabling Kappa Correction fixes this to have a better stereo view. |
|
Model
|
|
A model is a mathematical relationship providing the spatial orientation of images. A model can consist of a single image, monoscopic model. In most cases it is referenced to 2 images, with this being called a stereo model. |
|
Mono Vision Mode |
|
The view mode provides the viewing of a monoscopic model or an orthoimage. No special viewing device is required to view and use the imagery. 3D Z coordinates can be provided through the use of the collections associated DEM file. |
|
MyGeoPlayer |
|
MyGeoPlayer is a plugin to IE Internet Browser as well as a standalone application that allows the access and provides tools for the viewing and interaction with MyGeoWorld Collections. |
|
Side-by-Side Vision Mode
|
|
A stereo-viewing mode assisted by the use of a mirror stereoscope installed in front of the monitor. The left and right images are displayed “side-by-side” on the monitor. The ocular base of the mirror stereoscope is matched to the imagery base and the user is able to view the imagery in stereo. |
|
Stereo Model |
|
A Stereo model is a model with two images; left and right. This is similar to how the human vision works; left eye and right eye, where the brain analyzes both images to see in 3D. |
|
Stereo-ready Vision Mode |
| A stereo-viewing mode based on OpenGL that provides crystal clear full resolution stereo. A special video card with stereo-ready capabilities is required, as well as a stereo-ready viewing device. (A List of compatible video cards and viewing devices can be provided upon request – refer to your local representative for more information).

|
Vector File
|
All vectors, measurements, symbols and text inserted over a model is stored in a Vector File.
MyGeoPlayer supports the following Vector File formats:
- DVP 5.5 and DVP 6 (*.dvp)
- DGN V8 MicroStation (*.dgn)
- DWG Autodesk (*.dwg)
- DXF Autodesk (*.dxf)
- Text Point
