plot.Lines3D {pcds}

Plot a Lines3D object

Description

Plots the line together with the defining vectors (i.e., the initial and direction vectors).

Usage

## S3 method for class 'Lines3D'
plot(x, xlab = "x", ylab = "y", zlab = "z", phi = 40, theta = 40, ...)

Arguments

x

Object of class Lines3D.

xlab, ylab, zlab

Titles for the x, y, and z axes, respectively (default is xlab="x", ylab="y" and zlab="z").

theta, phi

The angles defining the viewing direction. theta gives the azimuthal direction and phi the colatitude. See persp3D for more details.

...

Additional parameters for plot.

Value

None

Examples

P<-c(1,10,3); Q<-c(1,1,3);
vecs<-rbind(P,Q)

Line3D(P,Q,.1,dir.vec=FALSE)

tr<-range(vecs);
tf<-(tr[2]-tr[1])*.1
#how far to go at the lower and upper ends in the x-coordinate
tsq<-seq(-tf*10-tf,tf*10+tf,l=3) #try also l=10, 20 or 100
