x3ptools (version 0.0.4)

x3p_image: Plot x3p object as an image

Description

Plot an interactive surface plot of the x3p matrix. This implementation uses the rgl package. In case rgl.useNULL is set to TRUE (i.e. no separate window will be opened), an rgl widget can be used to show the surface in the viewer window (see the example).

Usage

x3p_image(
  x3p,
  file = NULL,
  col = "#cd7f32",
  size = 750,
  zoom = 0.35,
  multiply = 5,
  update = FALSE,
  ...
)
image_x3p(
  x3p,
  file = NULL,
  col = "#cd7f32",
  size = c(750, 250),
  zoom = 0.35,
  multiply = 5,
  ...
)

Arguments

x3p

x3p object

file

file name for saving, if file is NULL the opengl device stays open. The file extension determines the type of output. Possible extensions are png, stl (suitable for 3d printing), or svg.

col

color specification

size

vector of width and height. If only one value is given, height or width will be adjusted proportionally to the dimensions of the surface matrix of the scan to reach an upper bound of size.

zoom

numeric value indicating the amount of zoom

multiply

exaggerate the relief by factor multiply

update

Boolean value indicating whether a scene should be updated (defaults to FALSE). If FALSE, a new rgl device is opened.

...

not used

Examples

save <- getOption("rgl.useNULL")
options(rgl.useNULL=TRUE)

logo <- x3p_read(system.file("csafe-logo.x3p", package="x3ptools"))
x3p_image(logo, size = c(741, 419), zoom=0.5)
# add crosscut:
logoplus <- x3p_add_hline(logo, yintercept = 50*.645e-6, color = "#e6bf98", size = 5)
x3p_image(logoplus, size = c(741, 419), zoom=0.5)
widget <- rgl::rglwidget()
if (interactive())
  widget

options(rgl.useNULL=save)
