STRETCH_CURVE

Description

Stretches the curve(s) defined in the 'CurvesNode' over the X axis by a factor defined in 'StretchNode'. You can specify the X coordinate at where the stretching begins with the 'StartNode' parameter. The stretching begins at 0 by default. The X coordinates are represented by the Sequence level in 'CurvesNode'. The Y coordinates are represented by the values of 'CurvesNode'.

Syntax

STRETCH_CURVE(CurvesNode, StretchNode [, StartNode])

Parameters

• CurvesNode: The definition of curves as a set of (X, Y) points in the coordinate system. X are values of the Sequence level in the parameter, Y values are the values of the parameter. It must contain the Sequence level.

• StretchNode: The stretch factor. It must not contain the Sequence level and only contain levels that are present in the CurvesNode parameter. Can also be a constant.

• StartNode: Where the stretching of the curve begins. It must not contain the Sequence level and only contain levels that are present in the CurvesNode parameter. Can also be a constant. It is an optional parameter. All the curves will start stretching 0 if omitted.
