# 3.9.4: Cull Curves

Fig.3.9.4.1: A data tree of line segments thinned out based on their mutual distance

Components like

**“Line Results on Shells”**may result in a dense pattern of lines. The**“Cull Curves”**- component lets you thin out the line segments based on their mutual distance. The input at**“C”**expects a data tree, where each branch contains curve segments which make up a stream line.**“LDist”**sets the minimum distance of curve segments from different branches below which a curve segment gets removed. Proximity is determined on the basis of equidistant control points along the curve segments. By default three points are used per segment. The number of points can be set via the**“NSamples”**-input.
