Plot an ellipsoid

Usage

# S3 method for ellipsoid
plot(
  x,
  add = TRUE,
  i = 0,
  levels = 1,
  res = 128,
  scale = 1,
  N = 2,
  xlab = "x",
  ylab = "y",
  ...
)

Arguments

x: ellipsoid
add: logical
i: Normal 1,2 or 3. Plot intersection of 3d ellipsoid.
levels: If i>0, draw this many levels from origin to tip of the axis
res: 2d resolution
scale: 1. use to enlarge or shrink
N: 2, iteration of refinement in 3D (resolution)
xlab: axis-label
ylab: axis-label
...: passed on to lines or rgl::shade3d

Details

#' For 3D ellipsoid, if i=1,2 or 3, plot 2D intersection of plane: i = 1 yz-plane; i = 2 xz-plane; i = 3 xy-plane.
