plot: Plot an object of class VoxelSpace

In AMAPVox: LiDAR Data Voxelisation

Plot an object of class VoxelSpace

Description

plot a VoxelSpace object.

Usage

plot(x, y, ...)

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

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

## Not run: 
# 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)])

## End(Not run)
