Cloud/Point Selection Tool
(PCISelectionTool)
Short Description
With this tool you can select clouds or points in different ways.
Usage
In the custom editor you have different buttons to chose how you want to select/deselect
the clouds or points. The single-, brushes- and areas-buttons allow
you to directly pick clouds or points with the mouse. With the actions- and
attribs-buttons you can perform some automatically selection by one click.
single:
- cloud: Select or deselect single clouds with the mouse.
- point: Select or deselect single points with the mouse.
brushes:
- circle: Use a circular brush to select or deselect points.
- quadratic: Use a quadratic brush to select or deselect points.
- brushsize: Here you can adjust the size of the brush
- surface mode: By activating surface mode, the brush tries to select/deselect
only those points of an object, which lie on the visible surface pointing to you. If
not in surface mode, all points you see inside the brush-area will be selected/deselected
not considering their distance or location.
areas:
- rectangle: Allows you to pull up a rectangular area to select/deselect points by moving the mouse with pressed mousebutton.
- circle: Allows you to pull up a circular area to select/deselect points by moving the mouse with pressed mousebutton.
actions:
- clear clouds: This button clears the cloud selection.
- all clouds: Press this button to select all clouds in the scene.
- clear points: After pressing this button, all points are deselected.
- all points: Press this button to select all points in the scene.
- invert points: This button inverts the point-selection. All selected points will be deselected afterwards and vice versa.
attribs:
Here you can select points by the attributess they have. Actually just selection-by-color is implemented, but this may be enhanced in future.
- color: By pressing this button all points with the specified color will be selected.
- color-box: (initialy a black box) Use this to chose a color.
- tolerance: Here you can adjust a tolerance-level for the color-selection. The higher the value the less precise the color search will be.
deselect:
If you enable this checkbox all of the operations above will deselect clouds or points instead
of selecting them. Alternatively you can hold down the <ctrl>-key while interacting
in the scene-window to change faster between selection and deselection.
