Rigid body transformations

Description

Applies a rigid body transformations to a landmark configuration or array

Usage

transx

negative shift in x-coordinates

transy

transz

negative shift in z-coordinates

thetax

Rotation about x-axis in degrees

thetay

Rotation about y-axis in degrees

thetaz

Rotation about z-axis in degrees

Value

The transformed coordinates (X - trans) Rx Ry Rz
