LerpPoints

Advanced

Module: FoundationLite

Linearly interpolates between two points.

Name Type Range Description
Input value
 inPoint0 Point2D
Input value
 inPoint1 Point2D
Input value
 inLambda Real - - Interpolation between the input points where 0.0 value is equal to inPoint0 and 1.0 to inPoint1
Output value
 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.
Hence when inLambda = 0,0, outPoint is equal to inPoint0, while for inLambda = 1,0 it's the same as inPoint1 and for inLambda = -1,0 - as (inPoint0 - inPoint1). Other inLambda values interpolate between the input points and beyond.
