tetraplot: Plot a static tetrahedral colorspace

In pavo: Perceptual Analysis, Visualization and Organization of Spectral Colour Data

Plot a static tetrahedral colorspace

Description

Produces a static 3D tetrahedral plot.

Usage

tetraplot(
  tcsdata,
  theta = 45,
  phi = 10,
  perspective = FALSE,
  range = c(1, 2),
  r = 1e+06,
  zoom = 1,
  achro = TRUE,
  achro.col = "grey",
  achro.size = 1,
  achro.line = FALSE,
  achro.lwd = 1,
  achro.lty = 3,
  tetrahedron = TRUE,
  vert.cex = 1,
  vert.range = c(1, 2),
  out.lwd = 1,
  out.lcol = "darkgrey",
  type = "p",
  labels = FALSE,
  gamut = FALSE,
  ...
)

Arguments

tcsdata	(required) a data frame, possibly a result from the colspace() or tcspace() function, containing values for the 'x', 'y' and 'z' coordinates as columns (labeled as such).
theta	angle to rotate the plot in the xy plane (defaults to 45).
phi	angle to rotate the plot in the yz plane (defaults to 10).
perspective	logical, should perspective be forced by using point size to reflect distance from the plane of view? (defaults to 'FALSE“)
range,	vert.range multiplier applied to cex and vert.cex, respectively, to indicate the size range variation reflecting the distance from the plane of view.
r	the distance of the eyepoint from the center of the plotting box. Very high values approximate an orthographic projection (defaults to 1e6). See persp() for details.
zoom	zooms in (values greater than 1) or out (values between 0 and 1) from the plotting area.
achro	should a point be plotted at the origin (defaults to TRUE)?
achro.line	logical. Should the achromatic line be plotted? (defaults to FALSE)
achro.lwd, achro.lty	graphical parameters for the achromatic coordinates.
tetrahedron	logical. Should the tetrahedron be plotted? (defaults to TRUE)
vert.cex	size of the points at the vertices (defaults to 1).
out.lwd, out.lcol	graphical parameters for the tetrahedral outline.
type	accepts a vector of length 1 or 2 with 'p' for points and/or 'l' for lines from the point to the base of the tetrahedron.
labels	logical. Should the name of each cone be printed next to the corresponding vertex?
gamut	logical. Should the polygon showing the possible colours given visual system and illuminant used in the analysis (defaults to FALSE). This option currently only works when qcatch = Qi.
...	additional graphical options. See par().

Value

tetraplot() creates a non-interactive 3D plot.

Examples

# For plotting
data(sicalis)
vis.sicalis <- vismodel(sicalis, visual = "avg.uv")
tcs.sicalis <- colspace(vis.sicalis, space = "tcs")
plot(tcs.sicalis)
