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:
