#include <vtkFrustumCoverageCuller.h>
Inheritance diagram for vtkFrustumCoverageCuller:
vtkFrustumCoverageCuller will cull props based on the coverage in the view frustum. The coverage is computed by enclosing the prop in a bounding sphere, projecting that to the viewing coordinate system, then taking a slice through the view frustum at the center of the sphere. This results in a circle on the plane slice through the view frustum. This circle is enclosed in a squared, and the fraction of the plane slice that this square covers is the coverage. This is a number between 0 and 1. If the number is less than the MinumumCoverage, the allocated render time for that prop is set to zero. If it is greater than the MaximumCoverage, the allocated render time is set to 1.0. In between, a linear ramp is used to convert coverage into allocated render time.

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkCuller. |

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from vtkCuller. |

Set/Get the maximum coverage - props with more coverage than this are given an allocated render time of 1.0 (the maximum) |
