Syntax
public static void SelectOuterPaths( AvlNet.Path[] inPaths, AvlNet.Point2D inCenterPoint, float inTolerance, out AvlNet.Path[] outOuterPaths )
Parameters
| Name | Type | Range | Default | Description | |
|---|---|---|---|---|---|
 | inPaths | AvlNet.Path | Input paths from which the outer ones will be selected. | ||
| inCenterPoint | AvlNet.Point2D | Reference point used to determine path visibility. | ||
| inTolerance | float | <0.0f, 1.0f> | 0.0f | Fraction of the path sections that are allowed to obstruct visibility of other paths not rendering the path not-outer. Default value: 0.0f. |
 | outOuterPaths | AvlNet.Path | Paths classified as outer. |

The operation select those paths from the inPaths array that do not obstruct the visibility of any other path. Visibility of a characteristic point is obstructed by a path iff the segment connecting this point to inCenterPoint intersect the path.
