displayPixelBoundaries: Plot HEALPix pixel boundaries

In rcosmo: Cosmic Microwave Background Data Analysis

Description

Plot the HEALPix pixel boundaries at nside

Usage

displayPixelBoundaries(
  nside,
  eps = pi/90,
  col = "gray",
  lwd = 1,
  ordering,
  incl.labels = 1:(12 * nside^2),
  nums.col = col,
  nums.size = 1,
  font = 2,
  depth_test = "always",
  ...
)

Arguments

nside	the HEALPix nside parameter (integer number 2^k)
eps	controls the smoothness of the plot, smaller eps implies more samples
col	the colour of plotted boundary lines
lwd	the thickness of the plotted boundary lines
ordering	optionally specify an ordering scheme from which to plot HEALPix pixel numbers. Can be either "ring" or "nested"
incl.labels	If ordering is specified then this parameter sets the pixel indices that will be displayed (default is all indices at nside)
nums.col	specifies the colour of pixel numbers if ordering is specified
nums.size	specifies the size of pixel numbers if ordering is specified
font	A numeric font number from 1 to 5, used if ordering is specified
depth_test	The depth test to be applied. This controls how resistant the plotted object is to being obscured. See rgl.material
...	arguments passed to rgl::plot3d

Value

Produces a plot of the HEALPix pixel boundaries.

Examples

displayPixelBoundaries(1, eps = pi/90, col = "red")
displayPixelBoundaries(2, eps = pi/90, col = "green")
