TwoPieceInterp

Discussion

THIS MODULE IS DEPRECATED AND NOT RECOMMENDED FOR NEW DESIGNS. PLEASE USE THE TwoPieceInterpV2 MODULE INSTEAD.

This module performs interpolation using two line segments with a knee between the two pieces. The parameter threshold specifies the point of intersection of the two lines. The kneeDepth specifies the curvature of the smooth region connecting the two line segments. If kneeDepth is zero, then there is no knee, simply two lines connected to each other at the threshold point. If kneeDepth is nonzero, then the curved region will begin at threshold-kneeDepth and ends at threshold+kneeDepth. The slopeL and slopeH are the slopes of the left hand side line and right hand side line respectively .
