| 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)" \ | |
