plot_stand {rTwig}

Plot Stand

Description

Plots multiple QSMs in a forest stand using the rgl library

Usage

plot_stand(
  qsms,
  radius_type = "modified",
  qsm_colors = NULL,
  cyl_sides = 8,
  clouds = NULL,
  pt_colors = NULL,
  pt_sizes = NULL,
  axes = TRUE
)

Arguments

qsms

A list of QSM cylinder data frames.

radius_type

Radius type as either "modified", "unmodified", or "old". Defaults to "modified".

qsm_colors

Optional qsm color parameters. Colors vector of hex colors with the same length as the qsms list. Defaults to distinct random colors.

cyl_sides

The number of sides in the polygon cross section. Defaults to 8, but can be increased to improve visual smoothness.

clouds

A list of point cloud data frames where the first three columns are the x, y, and z coordinates in the same coordinate system as the QSMs.

pt_colors

A vector of hex colors. Defaults to the same random color as the QSM.

pt_sizes

Size of the points as a number. Defaults to 0.1.

axes

Show plot axes. Defaults to TRUE.

Value

A rgl QSM plot

Examples

# Import QSMs
file1 <- system.file("extdata/QSM.mat", package = "rTwig")
qsm <- import_qsm(file1)
cylinder <- qsm$cylinder
cylinder <- update_cylinders(cylinder)

# Create a list of QSM cylinder data frames
qsms <- list(cylinder)

# Optionally import and create a list of point clouds
file2 <- system.file("extdata/cloud.txt", package = "rTwig")
cloud <- read.table(file2, header = FALSE)
clouds <- list(cloud)

# Plot QSMs and clouds
plot_stand(qsms = qsms, clouds = clouds)
