                       Tuple3D point)

countPlane

public void countPlane(Tuple3D a,
                       Tuple3D b,
                       Tuple3D c)

recountPlane

public void recountPlane(Tuple3D newNormal)

getCommonPoint

public Tuple3D getCommonPoint()

Used for testing the planes for equality. Can be used to obtain a point of plane (like in recountPlane()). Returns null if wrong equation (x, y, z coeficients == 0).

getCommonPoint

public Tuple3D getCommonPoint(double arg)

You can use it to obtain 2 different points and get a line. Used by getCommonVector(), getCommonLine();

getCommonVector

public Tuple3D getCommonVector()

getCommonLine

public Line3D getCommonLine()

project

public Tuple3D project(Tuple3D point)

distance

public double distance(Tuple3D point)

inPlane

public boolean inPlane(Tuple3D point)

perpendicularVector

public Tuple3D perpendicularVector(Tuple3D vectorInPlane)

inverseNormal

public void inverseNormal()

Will inverse normal vector of the plane, so it points to other half-space of the 3D space.
