Detailed Description
cull props based on frustum coverage
- Date:
- 2002/01/22 15:38:32
- Revision:
- 1.24
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.
