transformPoints
|
|
|
|
Description
|
|
Transforms the mesh points in the polyMesh directory according to the
|
|
translate, rotate and scale options.
|
|
|
|
Usage
|
|
Options are:
|
|
|
|
-translate vector
|
|
Translates the points by the given vector,
|
|
|
|
-rotate (vector vector)
|
|
Rotates the points from the first vector to the second,
|
|
|
|
or -yawPitchRoll (yawdegrees pitchdegrees rolldegrees)
|
|
or -rollPitchYaw (rolldegrees pitchdegrees yawdegrees)
|
|
|
|
-scale vector
|
|
Scales the points by the given vector.
|
|
|
|
The any or all of the three options may be specified and are processed
|
|
in the above order.
|
|
|
|
With -rotateFields (in combination with -rotate/yawPitchRoll/rollPitchYaw)
|
|
it will also read & transform vector & tensor fields.
|
|
|
|
Note:
|
|
yaw (rotation about z)
|
|
pitch (rotation about y)
|
|
roll (rotation about x)
