LerpSegments


Module: FoundationLite

Linearly interpolates between two segments.

Name Type Range Description
Input value inSegment0 Segment2D
Input value inSegment1 Segment2D
Input value inLambda Real - - Interpolation between the input segments where 0.0 value is equal to inSegment0 and 1.0 to inSegment1
Input value inIgnoreOrientation Bool
Output value outSegment Segment2D

Examples

Description of usage of this filter can be found in examples and tutorial: Pins.

LerpSegments performed on red inSegment0 and blue inSegment1 with inLambda = 0,25. Green is the resulting outSegment.

LerpSegments performed on red inSegment0 and blue inSegment1 with inLambda = -1,0. Green is the resulting outSegment.

Remarks

Please note that:
  • interpolation begins at inSegment0,
  • for positive inLambda values interpolation is performed in the direction of inSegment1 while for negative - in the direction of a segment which is the result of the following operation: (inSegment0 - inSegment1), in example a segment consisting of inSegment1 points mirrored by the corresponding inSegment0 points.
Hence when inLambda = 0,0, outSegment is equal to inSegment0, while for inLambda = 1,0 it's the same as inSegment1 and for inLambda = -1,0 - as (inSegment0 - inSegment1). Other inLambda values interpolate between the input segments and beyond.
