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, \
|
