Advanced Interpolation Parameters

---

The advanced interpolation parameters appear when ticking the corresponding box in the interpolation options menu:

1. Flatten

This parameter is used to reduce oscillations in the interpolation by approaching a linear interpolation.

Flatten = 0 : Totally smooth interpolation with minimized curvature

Flatten = 50 : Smooth interpolation with reduced curvature radius

Flatten = 100 : Linear interpolation

2. Squeeze

This parameter stretches the Zoom/Focus plane so that the interpolation has less oscillations along one parameter.

Squeeze = 0 : high frequency oscillations on focus, low frequency on zoom

Squeeze = 50 : isotropic interpolation, same effect on both parameters

Squeeze = 100 : high frequency oscillations on zoom, low frequency on focus

3. Smooth

This parameter handles the weight of measured points on the interpolation.

Smooth = 0 : interpolation goes exactly through the measured points

Smooth = 100 : The points are only a rough guide for the very smooth interpolation going between them

4. Clump

This parameter groups close points together, creating a new virtual point instead that is the average of the clumped points. The unit of the clump is the radius between 0 and 1 of the clump circle in the Z/F plane.
