The scene can be viewed in red-blue stereo mode when the checkbox “Stereo viewing” is activated. This feature is currently not supported for TerrainView-Globe™.

Configuring a view port for stereo rendering is simple to accomplish, as will be shown below. In the stereo viewing mode, physical-based parameters are very important. The reason for this can be traced back to the brains interpretations of the stereo images it receives, one from each eye. Since birth, our brain is trained to judge depth, often based on minute angle differences between the left-eye and right-eye images. The distance between the pupils of our eyes, called the inter-pupillary distance, or IPD, is responsible for generating the stereo image pairs needed for depth interpretation. For a typical human head, the IPD measures between 50 and 75 mm, with the average male having an IPD of about 64 mm. In order to generate accurately believable stereo 3D images, you should know this number. The second physical-based parameter associated with stereo viewing is the screen distance, or SD. SD comprises the distance between the viewer and the display surface. The SD parameter is important for shared surface configurations, such as Cathode Ray Tube (CRT) monitors and projection screens, where both eyes look at the same surface. For CRT monitors, SD is usually about 600 mm long, but may be much larger for larger surfaces. The screen intercept (SI) distance gives the virtual world distance at which rendered objects will appear at the real-world depth of the display surface. For example, if the screen distance, SD, is 600 mm, and SI is 30 meters, an object rendered at a distance of 30 meters in the virtual world appear to be at the real-world distance of the screen.
