LerpPoints
Linearly interpolates between two points.
Syntax
void avl::LerpPoints ( const avl::Point2D& inPoint0, const avl::Point2D& inPoint1, const float inLambda, avl::Point2D& outPoint )
Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
![]() |
inPoint0 | const Point2D& | |||
![]() |
inPoint1 | const Point2D& | |||
![]() |
inLambda | const float | -![]() ![]() |
0.5f | Interpolation between the input points where 0.0 value is equal to inPoint0 and 1.0 to inPoint1 |
![]() |
outPoint | Point2D& |
Examples
![]() |
LerpPoints performed on red inPoint0 and blue inPoint1 with inLambda = 0,25. Green is the resulting outPoint.
![]() |
LerpPoints performed on red inPoint0 and blue inPoint1 with inLambda = -1,0. Green is the resulting outPoint.
Remarks
Please note that:
- interpolation begins at inPoint0,
- for positive inLambda values interpolation is performed in the direction of inPoint1 while for negative - in the direction of a point which is the result of the following operation: (inPoint0 - inPoint1), in example a point acquired by mirroring inPoint1 by inPoint0.
