traj: Calculates shape intermediates.

Description

Given a Nef object, and two positions on the set defined by $PC_1$ and $PC_2$, calculates and plots intermediate shapes along the euclidean distance between these two shapes.

Usage

traj(Nef, fr = c(0, 0), to = c(1, 1), nb.int = 50, nb.pts= 500, save = FALSE, prog = TRUE, pause=TRUE)

Arguments

Nef

the Nef object

fr

a vector with two numerics indicating the $(x; y)$ coordinates of the starting point. If not provided, locator(1) is called

to

a vector with two numerics indicating the $(x; y)$ coordinates of the ending point. If not provided, locator(1) is called

nb.int

code{integer} giving the number of shape intermediates to calculate

nb.pts

code{integer} giving the number of points of the reconstructed outlines

save

logical indicating whether to save the images in a dedicated folder

prog

logical indicating whether to plot or not a progression bar

pause

logical indicating whether to ask the user to display successive intermediate shapes

Examples

data(bottles.nef)
traj(bottles.nef)
traj(bottles.nef, fr=c(-0.05, -0.05), to=c(0.15, 0.05))
