print.Lines3D: Print a Lines3D object

Description

Prints the call of the object of class "Lines3D", the coefficients of the line (in the form: x=x0 + A*t, y=y0 + B*t, and z=z0 + C*t), and the initial point together with the direction vector.

Usage

Value

The call of the object of class "Lines3D", the coefficients of the line (in the form: x=x0 + A*t, y=y0 + B*t, and z=z0 + C*t), and the initial point together with the direction vector.

Arguments
