public class TLcdMinimalVisibilityComposite extends Object implements ILcdVisibilityComposite
This ILcdVisibilityComposite
will output a minimum value of all provided
visibilities.
For instance, if an instance of TLcdMinimalVisibilityComposite
would obtain visibilities 0.2, 0.5 and 0.8 respectively, then
the result of this composite would be 0.2.
A possible use case for this composite implementation is the combination of multiple objects for the same 3D scene, each of which individually cause the scene to become more invisible in their projections away from the observer. For instance, if each object is a building, and each building has a viewshed, then combining the viewsheds of these buildings can be combined to form a single viewshed of the scene.
