<group OdGi_Classes>
|
This class implements conveyor nodes performing selections.
|
|
\remarks
|
|
Behavior of this node depends on the selection mode.
|
* If the mode is "fence", the points specify polyline vertices.
|
* If the mode is "crossing" or "window", the points specify polygon vertices. If exactly two points
|
are specified, the polygon is rectangle, with the points opposite vertices.
|
|
For any input primitive, this node performs the following actions:
|
|
1. It checks for primitive intersections with the polygon border.
|
|
2. If intersections are found, the node MARKS current drawable, and stops to handle the primitive.
|
|
3. If the mode is mode is "crossing", and the primitive is inside the polygon, the node
|
node MARKS the current drawable and stops to handle the primitive.
|
|
4. If the mode is "window", and primitive is outside the polygon, the node
|
MARKS the current drawable and stops to handle the primitive.
|
|
To MARK the current drawable is means to currentDrawableDesc()->markBySelection(true).
|
If the drawable is neither a compound object nor uses nesting, means currentDrawableDesc()->markToSkip(true)
|
|
This conveyor node is used for implementation OdGsBaseVectorizeView::select()
|
and does not produce any output.
