Class EvaluateRadiationForCfTreeSegmentForest

java.lang.Object

de.grogra.lignum.stlLignum.EvaluateRadiationForCfTreeSegmentForest

All Implemented Interfaces:

Mathsym

public class EvaluateRadiationForCfTreeSegmentForest
extends java.lang.Object
implements Mathsym

Is just like EvaluateRadiationForCfTreeSegment but uses instead of Firmaments diffuseRegionRadiationSum diffuseForestRegionRadiationSum, that is, the tree is surrounded by identical trees that are taken care with Lambert-Beer extinction. The tree level input parameters for diffuseForestRegionRadiationSum (needle area, extinction coefficient, tree height, height of crown base, stand density, and location of tree (for calculation of distance from tree stem)) are specified in the constructor. Note that this uses ShadingEffectOfCfTreeSegment (not Forest!) since it uses only directions from Firmament and they are just the same in diffuseRegionRadiationSum and diffuseForestRegionRadiationSum. (original Lignum comment) Translated from orignal C++ Lignum code.
