Application
    surfaceTransformPoints
 
Description
    Transform (translate, rotate, scale) a surface.
 
Usage
    \b surfaceTransformPoints "<transformations>" <input> <output>
    Supported transformations:
      - \par translate=<translation vector>
        Translational transformation by given vector
      - \par rotate=(<n1 vector> <n2 vector>)
        Rotational transformation from unit vector n1 to n2
      - \par Rx=<angle [deg] about x-axis>
        Rotational transformation by given angle about x-axis
      - \par Ry=<angle [deg] about y-axis>
        Rotational transformation by given angle about y-axis
      - \par Rz=<angle [deg] about z-axis>
        Rotational transformation by given angle about z-axis
      - \par Ra=<axis vector> <angle [deg] about axis>
        Rotational transformation by given angle about given axis
      - \par scale=<x-y-z scaling vector>
        Anisotropic scaling by the given vector in the x, y, z
        coordinate directions
 
    Example usage:
        surfaceTransformPoints \
            "translate=(-0.586 0 -0.156), \
            Ry=3.485, \
            translate=(0.586 0 0.156)" \
