The HPS::CullingControl class is a smart pointer that is tied to a database object. Using this object, you are able to control the various options related to culling, such as enabling or disabling back face culling, vector culling, and frustum culling. This table lists default values for the various segment attributes accessible from HPS::CullingControl.

( |
| ) |
|
