void avl::SegmentNormalVector ( const avl::Segment2D& inSegment, avl::Vector2D& outNormalVector )
Parameters
Description
Note that because of inaccuracies of floating-point arithmetic, some geometric operations (including this one) may lead to unpredictable results for degenerated cases. In this filter such a case occurs when an empty segment is given on input.
