NOTE Occlusion culling can only be used on a machine with an OpenGL 1.5
compliant graphics card. Also, occlusion culling is not used in a 2D workspace.
Adjust Presenter Materials
You can adjust the appearance of Presenter materials in the Scene View to
get optimum performance from your graphics card when navigating around
heavily textured scenes.

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.
