LerpPoints


Linearly interpolates between two points.

Name Type Range Description
inPoint0 Point2D
inPoint1 Point2D
inLambda Real - - 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.
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.
