summary.Lines3D {pcds}

Return a summary of a Lines3D object

Description

Returns the below information about the object:

call of the function defining the object, the defining vectors (i.e., initial and direction vectors), selected x, y, and z points on the line, equation of the line (in parametric form), and coefficients of the line.

Usage

## S3 method for class 'Lines3D'
summary(object, ...)

Arguments

object

An object of class Lines3D.

...

Additional parameters for summary.

Value

call of the function defining the object, the defining vectors (i.e., initial and direction vectors), selected x, y, and z points on the line, equation of the line (in parametric form), and coefficients of the line (for the form: x=x0 + A*t, y=y0 + B*t, and z=z0 + C*t).
