Cloud/Point Transformation Tool
(PCITransfEdit)
Short Description
With this tool you can move, rotate or scale clouds or a set of points.
Usage
This tool works on selected clouds or points only, so you have to select
them e.g. with the selection tool before. Then you can easily chose
an action in the custom editor and apply it by mouse interaction or
by entering discrete values. For rotation and scaling you need an associated
point called Pivot or center point in the following, which is shown as purple
marker in the 3D-window. This point defines the rotation- or scaling-center
and may be positioned by the user (see subsection center point).
mode:
- move: Move the selection in x- and y-direction with the left mouse button, in z-direction with the right mouse button.
- rotate: Rotate the selection around x- and y-axis with the left mouse button, around z-axis with the right mouse button.
- scale: Scales the selection uniformly. If you want to perform non-uniform scaling hold down the
<ctrl>-key. Attention: Non-uniform scaling is not a good idea for clouds due to some reasons.
transform:
- clouds: Let the tool work on selected clouds.
- points: Let the tool work on selected points.
- use world-coordinates: Here you can setup the tool to work in camera- or in world-coordinates. This affects the axes taken for transformation.
direct values:
Here you can enter exact values for x-, y- and z-directions. Apply the appropriate transformation by pressing the apply-button.
center point:
- move pivot: By enabling this button you can move the Pivot with the mouse as you can move points.
- center on selected clouds: Moves the Pivot to the centroid of the selected clouds.
- center on selected points: Moves the Pivot to the centroid of the selected points.
- lock pivot to cloud/point movement: Here you can set the Pivot to follow the clouds or points movement. E.g. check this box if you move a cloud
and want the Pivot to stay at the same place relative to this cloud.
stepwise:
- move by: By activating this checkbox, movement of clouds or points will be restricted to the fixed step size which you can enter in the floating-number-box behind it.
- rotate by: By activating this checkbox, rotation of clouds or points will be restricted to the fixed step size which you can enter in the floating-number-box behind it.
If you want to move or rotate the selection in defined steps, these settings are what you need. E.g. you can easily rotate your selection in steps of 45 degrees with this.
Tip: For easier and faster use, you alternatively can press the <shift>-key to toggle this function while interacting in the scene-window with the mouse.
display coordinate systems::
- show world c.s.: By enabling this checkbox you can display a green world coordinate system in the "world" origin.
- show pivot c.s.: Here you have the possibility to display a purple coordinate system in the Pivot point. If the box is grayed (standard), the coordinate system will only
be visible if a mouse button is pressed and thus you want to do some transformation. Of course you can show it permanently or never by fully enabling or disabling this checkbox.
- size: Here you can enter a scaling value for the display of the coordinate systems which will make them smaller or larger.
