Detailed Description
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.

This function returns the true type of the underlying object. This function is useful for finding the type of smart pointer objects that have been cast to more generic types.
- Warning
- This function must synchronize the database (by waiting for all pending database operations to complete) in order to know the type status of this object with certainty. Therefore this function can negatively impact performance. You should vigorously avoid using this function in high-traffic or peformance-critical areas of your code.
- Returns
- The true type of the object in question.
