CMPoint3f

public CMPoint3f()

creates a default point object. (x,y,z) is set to (0.0f, 0.0f, 0.0f)

CMPoint3f

public CMPoint3f(float x,
 float y,
 float z)

creates an point object.

Parameters:

x - - the value of x axis

y - - the value of y axis

z - - the value of z axis

Method Details

setPoint

public void setPoint(float x,
 float y,
 float z)

sets the position information of the point object.

Parameters:

x - - the value of x axis

y - - the value of y axis

z - - the value of z axis

distance

public float distance(CMPoint3f p1)

calculates the Euclidean distance between this point and another point (p1).

Parameters:

p1 - - the point object from which this object calculates distance.

Returns:

- the distance between this object and p1.

distanceSquared

public float distanceSquared(CMPoint3f p1)

calculates the Euclidean squared distance between this point and another point (p1).

Parameters:

p1 - - the point object from which this object calculates distance.

Returns:

- the squared distance between this object and p1.
