3D Input Devices
NVIDIA QuadroView is pre-configured to work with the following 3D input
devices when you are in QuadroView “Examiner Viewer” on page 14 mode.
• Logitech LogiCad Magellan 3D/Space Mouse, including CyberPuck
• Spacetec SpaceController
Using these devices, you can rotate and move the scene in real-time. You can
adjust the sensitivity of the 3D input devices by using the “3D Input Toolbar”
on page 50 which appears automatically when you select a 3D input device.
Option Description
Backface Culling When this option is checked, backfaces of polygons are excluded when
rendering the scene, which makes the process of rendering faster. You can
also activate this option for transparent objects if you can see rendering
artifacts; however, not checking this option yields better results for other
types of objects.
Fast Animation Fast Animation is turned on by default and used to speed up the
animation. Each Light Source slows down the rendering while rotating or
moving the scene.
When Fast Animation is checked, you can turn off all lights and only use
the Headlight while moving the scene
Complexity In order to control the quality of rendering, VRML (.WRL) files and Open
Inventor (.IV) files may contain elements that react to the Complexity
setting.
The higher the complexity, the lower the overall rendering performance.
Texture Quality To control the quality of rendering, VRML (.WRL) files and Open
Inventor (.IV) files may contain textures that react to the Texture Quality
setting.
The higher the texture quality, the lower the overall rendering
performance.
Default Restores all values to their standard settings.
