Culling lets you navigate and manipulate large and complex scenes at interactive rates by intelligently hiding less-important objects as you work.
In Autodesk Navisworks, you can use the following methods of culling objects:
- Area - the objects’ size in pixels determines whether the objects are rendered or not. By default, any objects smaller than 1x1 pixels in size are discarded.
- Backface - by default, only the front face of every polygon is drawn in Autodesk Navisworks. Sometimes, during the conversion process the front and back face of polygons get mixed, in which case, you need to adjust the Backface option.
- Near and Far Clipping Planes (frustum culling) - objects closer to the camera than the near clipping plane or beyond the far clipping plane are not drawn. You can let Autodesk Navisworks automatically constrain the location of the clipping planes, or you can constrain their location manually.
Note: Backface and Clipping Planes are not used in a 2D workspace.
