SegmentNormalVector
Computes an unitary vector perpendicular to the segment.
Syntax
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.

SegmentNormalVector performed on a segment with parameters: X1 = 50, Y1 = 50, X2 = 300, Y2 = 300.
outNormalVector result shown on the right picture.
