SegmentOrientation
| Header: | AVL.h |
|---|---|
| Namespace: | avl |
| Module: | FoundationLite |
Computes the orientation of a segment.
Syntax
C++
C#
void avl::SegmentOrientation ( const avl::Segment2D& inSegment, avl::AngleRange::Type inAngleRange, float& outOrientationAngle )
Parameters
| Name | Type | Default | Description | |
|---|---|---|---|---|
 |
inSegment | const Segment2D& | ||
|
inAngleRange | AngleRange::Type | _0_180 | Switches between 0-90, 0-180 or 0-360 degrees |
 |
outOrientationAngle | float& |
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.
Examples
 |
SegmentOrientation performed on a segment with parameters: X1 = 50, Y1 = 50, X2 = 300, Y2 = 300 and inAngleRange set to _0_180.
outOrientationAngle returns 45.
