No Smoothing Applied

Below are the contours that were created from the previous post, with no smoothing applied.

Smooth Contours

Tick the <Smooth Contours> option, to smooth the contours.

Hit the <Process> button to re-create the contour strings and labels.

The contours have now been rounded to look like a smoother string. Basically more points are added to the string when a change of direction occurs.

Preserve String Points

Once the <Smooth Contours> option is ticked, the ‘Preserve String Points’ option becomes available.

Tick the <Preserve String Points> option.

Hit the <Process> button to re-create the contour strings and labels.

The contours have now been rounded to look like a smoother string, but ensures that the contour string still goes through the original vertices of the original contour strings.

Another Example – Closer up

Here both the ‘Smooth Contours’ and the ‘Preserve String Points’ options are ticked, and the contours have been smoothed, as well as passing through the original contour string vertices.

Magenta Strings = Original Contour Strings

Grey Strings = New Smoothed Contour Strings

Here only the ‘Smooth Contours’ option is ticked, and the contours have been smoothed.

Magenta Strings = Original Contour Strings

Grey Strings = New Smoothed Contour Strings
