Plot an object of class VoxelSpace

plot a VoxelSpace object.

plot(x, y, ...)

# S4 method for VoxelSpace,missing
plot(
  x,
  y,
  variable.name = "nbSampling",
  palette = "viridis",
  bg.color = "lightgrey",
  width = 640,
  voxel.size = 5,
  unsampled.discard = TRUE,
  empty.discard = TRUE,
  ...

# S4 method for VoxelSpace,data.table
plot(
  x,
  y,
  variable.name = "nbSampling",
  palette = "viridis",

Arguments

x

the object of class VoxelSpace to plot

y

a subset of voxel index. A data.table with i, j, k columns. Missing parameter means whole voxel space.

...

additional parameters which will be passed to rgl::plot3d().

variable.name

character, the name of the variable to plot

palette

character, a valid palette name (one of hcl.pals())

bg.color

character, a valid background color name (one of colors())

width

numeric, the width of the windows

voxel.size

numeric, the size of voxel in pixels

unsampled.discard

logical, whether to discard unsampled voxel

empty.discard

logical, whether to discard empty voxel (no hit)

Details

Plot an object of class VoxelSpace in a 3d device. By default it plots the sampling intensity but the user can choose any variable available in the voxel file.

Examples

if (FALSE) {
# load a voxel file
vxsp <- readVoxelSpace(system.file("extdata", "tls_sample.vox", package = "AMAPVox"))
# plot sampling intensity by default
plot(vxsp)
# plot PAD
plot(vxsp, variable.name = "PadBVTotal", palette = "YlOrRd")
# plot a subset
plot(vxsp, vxsp@data[k > 4, .(i, j, k)])
}
