Stereo Viewing
Settings → Stereo Viewing
Sets options for using Adams View with stereo viewing. Stereo viewing is available on all Linux platforms but not Windows.
Before running Adams View in stereo-viewing mode, you need to set the MDI_STEREO environment variable MDI_STEREO (setenv MDI_STEREO 1). Learn more about setting
Adams View Environment Variables.
Stereo viewing is only available when running Native OpenGL graphics with the OpenGL_Software_Assisted registry setting set to disabled. You use the Registry Editor.
To set this registry setting:
1. From the Adams Toolbar, right-click the
Toolbar tool

, and then select
Registry Editor.
The Registry Editor appears.
2. Select AView → Preferences → Graphics → OpenGL_Software_Assisted.
Using Stereo Viewing on SGI Machines
There are two types of stereo views available on SGI machines:
■Above-and-below viewing - The first, and least useful, is above-and-below viewing. This type of viewing is used with non-stereo- ready hardware and splits the screen into two halfs, a top half and bottom half. The result is that the screen size in pixels is effectively cut in half in the vertical direction. For example, on a monitor set for a screen size 1024 x 768 pixels, the screen size changes to 1024 x 384. This changes the aspect ratio of the screen and of the resulting images displayed within Adams View and Adams PostProcessor. They appear to be one half as tall as they should be.
■Interlaced stereo viewing - The second type of viewing is Interlaced stereo viewing, which is available on stereo-capable graphics cards. This approach has the advantage that the screen aspect ratio is not changed and, therefore, the resulting images maintain the same proportions has their non-stereo counterparts. To enable this mode in the current Adams code, the video format for the monitor must be set to a format that supports interlaced stereo viewing. To do this, use the SGI setmon(1) shell command. For example, on a SGI tezro machine with a V12 graphics card, you could use the following command:
/usr/gfx/setmon -n 1280x1024_100s
For the option: | Do the following: |
|---|
Stereo viewing | Select to enable stereo viewing. |
Depth of Field | Slide to control the depth of the perspective matrix. |
Eye Separation | Slide to control of offset between the left and right modeling views. |
Parallax | Control the type of parallax view used to display the model: ■Positive - Positive parallax viewing produces images that appear to be within the space of the monitor. For engineering purposes where objects are often cut off by the window borders or partially obscured by dialog boxes, positive parallax viewing produces images that are less confusing to the viewer and are, therefore, easier to view. ■Negative - Negative parallax viewing produces images that appear to float in space in front of the display. Viewing floating images that are partially obscured by interface items produces confusing cues to the viewer. While the image appears in front of the screen, the interface items appear to be on the screen but these interface items can obscure part of the image. These conflicting inputs can be confusing and lead to extra strain. |
Eye Position | Use with Negative parallax viewing and use it to control how far the image floats in front of the screen. |
