In r3js: 'WebGL'-Based 3D Plotting using the 'three.js' Library

Add lines segments a 3js object

Description

Add lines segments a 3js object

Usage

segments3js(
  data3js,
  x,
  y,
  z,
  lwd = 1,
  col = "black",
  highlight,
  geometry = FALSE,
  ...
)

Arguments

data3js	The data3js object
x	x coords
y	y coords
z	z coords
lwd	line width
col	line color
highlight	highlight characteristics (see highlight3ks())
geometry	logical, should the lines be rendered as a physical geometries
...	further parameters to pass to material3js()

Value

Returns an updated data3js object

Examples

# Draw three lines
x <- seq(from = 0, to = 6, length.out = 100)
y <- cos(x*5)
z <- sin(x*5)
linecols <- rainbow(100)

p <- plot3js(
  xlim = c(0, 6),
  ylim = c(0, 6),
  zlim = c(-1, 1),
  aspect = c(1, 1, 1),
  label_axes = FALSE
)

# Add a line using the linegl representation
p <- segments3js(
  data3js = p,
  x, y + 1, z,
  col = linecols
)

# Add a thicker line using the linegl representation
p <- segments3js(
  data3js = p,
  x, y + 3, z,
  lwd = 3,
  col = linecols
)

# Add a line as a physical geometry to the plot
p <- segments3js(
  data3js = p,
  x, y + 5, z,
  lwd = 0.2,
  geometry = TRUE,
  col = "blue" # Currently only supports fixed colors
)

# View the plot
r3js(p, rotation = c(0, 0, 0), zoom = 2)
