Compose homogeneous affine matrix from CMTK registration parameters

cmtkparams2affmat( params = NULL, tx = 0, ty = 0, tz = 0, rx = 0, ry = 0, rz = 0, sx = 1, sy = 1, sz = 1, shx = 0, shy = 0, shz = 0, cx = 0, cy = 0, cz = 0, legacy = NA )

params | 5x3 matrix of CMTK registration parameters or list of length 5. |
---|---|

tx, ty, tz | Translation along x, y and z axes (default 0) |

rx, ry, rz | Rotation about x, y and z axes (in degrees, default 0) |

sx, sy, sz | Scale for x, y and z axes (default 1) |

shx, shy, shz | Shear for x,y,z axes (default 0) |

cx, cy, cz | Centre for rotation |

legacy | Whether to assume that parameters are in the format used by CMTK <=2.4.0 (default value NA implies FALSE, see details). |

4x4 homogeneous affine transformation matrix

If the `legacy`

parameter is not set explicitly, then it will
be set to `TRUE`

if params has a version attribute <2.4 or FALSE
otherwise.

translation and centre components are assumed to be in physical coordinates.
