Stereo Rendering
Stereoscopic viewing in Autodesk Navisworks allows the viewing of the 3D
model through stereo-enabled hardware, including active and passive stereo
viewing glasses in conjunction with both CRT screens and dedicated projectors.
IMPORTANT Using stereo rendering requires the host computer have an OpenGL
graphics card with stereo support. Additionally, some drivers require stereo to be
explicitly enabled in the driver and may require lower color or resolution settings
before the stereo rendering becomes available.
When the video output is in stereo mode, the view looks blurred without the
correct glasses being worn. If the camera is in orthographic mode, it needs to
be set to perspective for the effect to work correctly.
NOTE As the view for each eye has to be rendered separately it is not possible to
support incremental filling in of detail in stereo mode. The detail appears when
rendering is complete. Progress can be seen using the bar in the status area, and
it is still possible to interrupt and start interacting again at any time.
In focal point-based navigation modes (such as orbit, free orbit and constrained
orbit) the model is positioned so that parts closer than the focal point appear
in front of the screen, with the rest behind. In other navigation modes (such
as walk and fly), the focal point is set so that any avatar will be level with the
screen. Objects between you and the avatar will appear in front of the screen.
You can adjust the out of screen effect in the Stereo Options dialog box.
To enable stereo rendering
Click View tab Stereo panel Enable Stereo
.
NOTE This option is only available if you have the required hardware, and the
correct driver and display settings.
To adjust the stereo effects
1 Click View tab Stereo panel Stereo Options tool launcher
.
2 In the Stereo Options dialog box, move the Magnitude slider to vary
the strength of the effect.
3 To adjust the out of screen effect, select the Enable check box, and then
move the slider to control how much of the scene appears out of the
screen during navigation.
