Constructor Detail

GroundProfileFromFile

public GroundProfileFromFile(java.lang.String BDITerrainFilePath,
                             int maxPointsInLeaves,
                             javax.media.j3d.Transform3D transform3D)

GroundProfileFromFile

public GroundProfileFromFile(java.lang.String BDITerrainFilePath,
                             javax.media.j3d.Transform3D transform3D)

GroundProfileFromFile

public GroundProfileFromFile(java.lang.String BDITerrainFilePath,
                             int maxPointsInLeaves,
                             javax.media.j3d.Transform3D transform3D,
                             GroundProfileFromFile.VariableType[] variableOrder)

Creates a KDTree from an array of (X, Y) terrain points and an equally sized array of (Z) terrain heights. The value MaxPointsInLeaves specifies the maximum number of points in a leaf Node. Use a small value (5-20) unless building the tree takes too long.

Parameters:

points - double[][]

maxPointsInLeaves - int

Method Detail

loadPoints3D

public static double[][] loadPoints3D(java.lang.String filename,
                                      javax.media.j3d.Transform3D transform3D,
                                      GroundProfileFromFile.VariableType[] variableOrder)

Loads an ASCII file of 3D points. The first line of the file must contain the number of points, and all subsequent lines must contain three scalar values.

Parameters:

filename - String

Returns:

OneDTerrainGrid

loadPoints3D

public static double[][] loadPoints3D(java.io.BufferedReader bufferedReader,
                                      javax.media.j3d.Transform3D transform3D,
                                      GroundProfileFromFile.VariableType[] variableOrder)

Loads terrain data from a BufferedReader and returns a 2D array of doubles. The first line of the file must contain the number of points, and all subsequent lines must contain three scalar values. Returns null if the operation does not succeed.

Parameters:

bufferedReader - BufferedReader

Returns:

BreadthFirstStateEnumerator
