ref.srctodest.add: Linking two existing frames of reference in T.MAT

Description

The ref.srctodest.add function links the source frame of reference with the destination frame of reference.

Usage

ref.srctodest.add(src.ref, dest.ref, TM = diag(4), T.MAT = NULL)

Value

Returns a "t.mat" class object, which contains the transfer matrices from or to dest.ref pseudonym of the new frame of reference. If the T.MAT is NULL, then the returned object will contain only 4 matrices: "src.ref<-src.ref", "src.ref<-dest.ref", "dest.ref<- dest.ref", "dest.ref<-src.ref".

Arguments

src.ref

Character string, pseudonym of the source frame of reference.

dest.ref

Character string, pseudonym of the destination frame of reference.

TM

4x4 tansfert matrix for moving from src.ref to dest.ref.

T.MAT

"t.mat" class object created by load.patient.from.dicom, load.patient.from.Rdcm or load.T.MAT. If T.MAT = NULL, then only the link between src.ref and dest.ref is established.

Examples

local.Tmat <-  ref.srctodest.add ("ref1","ref2", 
                                  TM = matrix(c (0.5, -sin (pi / 3), 0, 0,
                                                 sin (pi / 3), 0.5, 0, 0,
                                                 0, 0, 1, 0, 0, 0, 0, 1),
                                              ncol = 4))
