Method Detail

calcDist

public static float calcDist(float x,
                             float y)

Calculate the distance between two X and Y points assuming that their counterparts are 0 using Pitagora's theorem.

Parameters:

x - X's coordonate of the first point (Y=0)

y - Y's coordonate of the second point (X=0)

Returns:

distance between [X, 0] and [0, Y] as a float

calcDist

public static float calcDist(java.awt.Point p1,
                             java.awt.Point p2)

Calculate the distance between two points (p1 and p2).

Parameters:

p1 - first point

p2 - second point

Returns:

the distance between p1 and p2

calcX

public static float calcX(java.awt.Point initP,
                          float dist,
                          float angle)

Calculate the X coordinate of a point situated at distance dist, angle angle from a given point initP.

Parameters:

initP - reference point

dist - distance from the reference point to the desired point

angle - angle from the reference point to the desired point

Returns:

the X coordinate of the point

calcY

public static float calcY(java.awt.Point initP,
                          float dist,
                          float angle)

Calculate the Y coordinate of a point situated at distance dist, angle angle from a given point initP.

Parameters:

initP - reference point

dist - distance from the reference point to the desired point

angle - angle from the reference point to the desired point

Returns:

the Y coordinate of the point

calcDistPoint

public static java.awt.Point calcDistPoint(java.awt.Point initP,
                                           float dist,
                                           float angle)

Calculate the coordinates of a point situated at distance dist, angle angle from a given point initP.

Parameters:

initP - reference point

dist - distance from the reference point to the desired point

angle - angle from the reference point to the desired point

Returns:

the coordinates of the new point as a Point (AWT)

calcAngle

public static float calcAngle(java.awt.Point p1,
                              java.awt.Point p2)

Calculate the angle between the line determined by the two points and the horizontal axis.

Parameters:

p1 - First point

p2 - Second point

Returns:

the angle as an integer
