lengthThreshold : MESHFREE will cluster all those geometry node points, whose distance is less than the given threshold.
Prior to the clustering, all node points obtain an importance-weight. Points on a geometry edge have a higher weight than
regular node points.
The new location of the clustered points \( NP_1 , NP_2\) is the mean value \( \mathbf{x}_{clustered} = \frac{1}{2} \left( \mathbf{x}_{NP_1} + \mathbf{x}_{NP_2} \right)\), if the weights are equal.
Otherwise, \( \mathbf{x}_{clustered} = \mathbf{x}_{NP_k}\) where \( {NP_k}\) is the index with the bigger weight.
