display.3D.contour {espadon}

Display the 3D contours of the RoI

Description

The display.3D.contour function performs a 3D display of the selected RoI in the chosen coordinate system.

Usage

display.3D.contour(
  struct,
  roi.name = NULL,
  roi.sname = NULL,
  roi.idx = NULL,
  roi.col = NULL,
  roi.print = FALSE,
  roi.lwd = 1,
  roi.cex = 1,
  display.ref = struct$ref.pseudo,
  T.MAT = NULL,
  FoR.axis = FALSE,
  FoR.col = "black"
)

Arguments

struct

"struct" class object. See espadon.class for class definitions.

roi.name

Vector of exact names of the RoI in the struct object. By default roi.name = NULL. See Details.

roi.sname

Vector of names or parts of names of the RoI in the struct object. By default roi.sname = NULL. See Details.

roi.idx

Vector of indices of the RoI that belong to the struct object. By default roi.idx = NULL. See Details.

roi.col

Color of the RoI. If roi.col = NULL (default),the RoI colors are specified in the struct$roi.info.

roi.print

Boolean vector indicating whether to display the pseudonym of the RoI.

roi.lwd

Line width of the RoI, by default at 1.

roi.cex

Numeric character expansion factor of RoI name if roi.print = TRUE, defaults to 1.

display.ref

Pseudonym of frame of reference of the display.

T.MAT

"t.mat" class object, created by load.patient.from.Rdcm or load.T.MAT. If T.MAT = NULL, display.ref must be equal to NULL or to struct$ref.pseudo.

FoR.axis

Boolean or numeric, by default set to FALSE. If FoR.axis = TRUE, the function displays 200 mm length director vectors of the frame of reference. If FoR.axis is numeric, it represent the length in mm of the director vectors.

FoR.col

Color of the frame of reference.

Details

If roi.name, roi.sname, and roi.idx are all NULL, then all of the RoI are selected.

Value

If the concerned regions of interest (RoI) struct exist, it displays the 3D contours of these RoI in the current RGL window if it exists, in a new window otherwise.

Examples

# loading of toy-patient objects (decrease dxyz for better result)
step <- 4
patient <- toy.load.patient (modality = "rtstruct", roi.name = "eye",
                             dxyz = rep (step, 3))
library (rgl)
open3d()
bg3d ("black")
display.3D.contour (struct = patient$rtstruct[[1]], roi.print = TRUE)
