Rotate

Rotate command lets you rotate a point cloud interactively. The point cloud is rotated around a center point and only in horizontal direction.

To rotate a point cloud:

1. Select Rotate command from the Measurement pulldown menu.

This opens the Rotate measurement dialog:

rotate

2. Define settings.

3. Place a data click inside a view in order to define the center point of the rotation.

If the mouse pointer is moved, a temporary line illustrates the base line for the rotation.

4. Place another data click inside the view in order to define the origin point of the rotation (= end point of the base line).

If the mouse pointer is moved, a temporary line illustrates the direction and angle of the rotation.

5. Place another data click inside the view in order to define the destination point of the rotation (= rotation direction and angle).

This rotates the point cloud to the new position.

SETTING

EFFECT

Measurement

Points that are effected by the rotation: points from all scans or only from one specific scan. The list contains all scan numbers that are available in the loaded point cloud.

Rotate

Rotation method:

By mouse clicks - source and target points for computing the transformation are defined manually. No additional settings are required for this method.

By normal vectors - rotate the cloud to make the dominant normal vector direction point up.

90 deg clockwise - 90 degrees around vertical axis in clockwise direction. Sample center defines the rotation center point.

180 deg - 180 degrees around vertical axis. Sample center defines the rotation center point.

90 deg counter clockwise - 90 degrees around vertical axis in counter clockwise direction. Sample center defines the rotation center point.

Apply to trajectories

If on, the rotation is applied to active trajectories / scanner positions.

Apply to images

If on, the rotation is applied to the loaded image list.
