	ftl::Array<fil::Path>& outInnerPaths
)

Parameters

Name Type Range Default Description
Input value inPaths const Array<Path>& Input paths from which the inner ones will be selected
Input value inCenterPoint const Point2D& Reference point used to determine path visibility
Input value inTolerance float 0.0 - 1.0 0.0f Fraction of the path characteristic points that are allowed to be invisible from the inCenterPoint not rendering the path not-inner
Output value outInnerPaths Array<Path>& Paths classified as inner
