   This algorithm takes a polygon or line layer and generates a new one in which the geometries have a larger number of vertices than the original one. The geometries are densified by adding regularly placed extra nodes inside each segment so that the maximum distance between any two nodes does not exceed the specified distance.
 
   E.g. specifying a distance 3 would cause the segment [0 0] -> [10 0] to be converted to [0 0] -> [2.5 0] -> [5 0] -> [7.5 0] -> [10 0], since 3 extra nodes are required on the segment and spacing these at 2.5 increments allows them to be evenly spaced over the segment.
