Constructor Detail

DistanceMeter

public DistanceMeter(javax.vecmath.Vector3d a,
                     javax.vecmath.Vector3d b,
                     javax.vecmath.Vector3d c)

Creates a DistanceMeter using 3 points to calculate a 2 dimensional Area in 3d worldspace. Then we calculate some numbers to calculate the distance of a given point without solving the equation system

Parameters:

a - vector describing first point

b - vector describing second point

c - vector describing third point

Method Detail

testlinearab

private boolean testlinearab(javax.vecmath.Vector3d a,
                             javax.vecmath.Vector3d b)

This function tests if the two given vectors are pointing to the same direction

getDistance

public double getDistance(javax.vecmath.Vector3d ov)

This function calculates the distance between a given point and the area used to create DistanceMeter

Parameters:

ov - the 'Ortsvektor' of the point
