rtorus

Generate points in the torus

This function generates n random points within the torus whose minor radius is r, major radius is R and center is ct.

rtorus(n, r, R, ct = c(0, 0, 0), rotx = NULL)

`n`	Number of observations.
`r`	Minor radius (radius of the tube).
`R`	Major radius (distance from the center of the tube to the center of the torus).
`ct`	A vector with the coordinates of the center of the torus.
`rotx`	If not NULL, a rotation through an angle `rotx` (in radians) about the x-axis is performed.

T1 <- rtorus(2000, 0.5, 2.5)
rgl.bbox()
rgl.points(T1, col = 4)

T2 <- rtorus(2000, 0.5, 2.5, ct = c(2, 0, 0.5), rotx = pi/2)
rgl.points(T2, col = 2)
