List of Parameter Types for Shape Interpolation
One of the following values:
PARAM_SIMPLE - Parameter space based on segments.
This simple interpolation is interpolating based on parameter space
-- If a spline has 4 segments, the first segment is parameter
values 0-0.25, the second 0.25-0.5, the third 0.5-0.75 and the
fourth 0.75-1.0. This is regardless of the length of each
segment.
PARAM_NORMALIZED - Parameter space normalized to
curve length. This interpolation normalizes the parameter space to
distance along the length of a spline. So parameter space 0 is the
start, 1.0 is the end and 0.5 is halfway along the actual length of
the curve.
