Plot 3D Delaunay tessellation — plotDelaunay3D • tessellation

Plot a 3D Delaunay tessellation with rgl.

Usage

plotDelaunay3D(
  tessellation,
  color = "distinct",
  hue = "random",
  luminosity = "light",
  alpha = 0.3,
  exteriorEdgesAsTubes = FALSE,
  tubeRadius,
  tubeColor
)

Arguments

tessellation: the output of delaunay
color: controls the filling colors of the tetrahedra, either FALSE for no color, "random" to use randomColor, or "distinct" to use distinctColorPalette
hue, luminosity: if color = "random", these arguments are passed to randomColor
alpha: opacity, number between 0 and 1
exteriorEdgesAsTubes: Boolean, whether to plot the exterior edges as tubes; in order to use this feature, you need to set exteriorEdges = TRUE in the delaunay function
tubeRadius: if exteriorEdgesAsTubes = TRUE, the radius of the tubes
tubeColor: if exteriorEdgesAsTubes = TRUE, the color of the tubes

Value

No value, just renders a 3D plot.

Examples

library(tessellation)
pts <- rbind(
  c(-5, -5,  16),
  c(-5,  8,   3),
  c(4,  -1,   3),
  c(4,  -5,   7),
  c(4,  -1, -10),
  c(4,  -5, -10),
  c(-5,  8, -10),
  c(-5, -5, -10)
)
tess <- delaunay(pts)
library(rgl)
open3d(windowRect = c(50, 50, 562, 562))
plotDelaunay3D(tess)
open3d(windowRect = c(50, 50, 562, 562))
plotDelaunay3D(
  tess, exteriorEdgesAsTubes = TRUE, tubeRadius = 0.3, tubeColor = "yellow"
)
#> Warning: You didn't set the option `exteriorEdges=TRUE` in the `delaunay` function, therefore the option `exteriorEdgesAsTubes` is ignored.
