Low level triangulation mesh plotting

Description

Plots a triangulation mesh using rgl.

Usage

plot_rgl(x, ...)

lines_rgl(x, ..., add = TRUE)

## S3 method for class 'fm_segm'
lines_rgl(
  x,
  loc = NULL,
  col = NULL,
  colors = c("black", "blue", "red", "green"),
  ...,
  add = TRUE
)

## S3 method for class 'fm_mesh_2d'
plot_rgl(
  x,
  col = "white",
  color.axis = NULL,
  color.n = 512,
  color.palette = cm.colors,
  color.truncate = FALSE,
  alpha = NULL,
  lwd = 1,
  specular = "black",
  draw.vertices = TRUE,
  draw.edges = TRUE,
  draw.faces = TRUE,
  draw.segments = draw.edges,
  size = 2,
  edge.color = rgb(0.3, 0.3, 0.3),
  t.sub = seq_len(nrow(x$graph$tv)),
  visibility = "",
  S = deprecated(),
  add = FALSE,
  ...
)

## S3 method for class 'fm_segm'
plot_rgl(x, ..., add = FALSE)

## S3 method for class 'fm_segm_list'
plot_rgl(x, ...)

## S3 method for class 'fm_segm_list'
lines_rgl(x, ...)

Arguments

x	A fm_mesh_2d() object
...	Additional parameters passed to and from other methods.
add	If TRUE, adds to the current plot instead of starting a new one.
loc	Point locations to be used if x$loc is NULL.
col	Segment color specification.
colors	Colors to cycle through if col is NULL.
color.axis	The min/max limit values for the color mapping.
color.n	The number of colors to use in the color palette.
color.palette	A color palette function.
color.truncate	If TRUE, truncate the colors at the color axis limits.
alpha	Transparency/opaqueness values. See rgl.material.
lwd	Line width for edges. See rgl.material.
specular	Specular color. See rgl.material.
draw.vertices	If TRUE, draw triangle vertices.
draw.edges	If TRUE, draw triangle edges.
draw.faces	If TRUE, draw triangles.
draw.segments	If TRUE, draw boundary and interior constraint edges more prominently.
size	Size for vertex points.
edge.color	Edge color specification.
t.sub	Optional triangle index subset to be drawn.
visibility	If "front" only display mesh faces with normal pointing towards the camera.
S	Deprecated.

Value

An rgl device identifier, invisibly.
