This module creates a tube that connect all the given points. The tube has spheres at the ends. If the input mesh has a scalar node data, it
is used to color the tube, otherwise the values 1..N are internally assigned to the nodes. The tube radius is proportional to the point values.
||Mesh or Mesh plus Node_Data
||The set of points that should be connected by the tube.
||Scale factor for the radius of the tube to be created.
||Number of facets for the tube.
||Experimental! Smooth the tube reducing the number of intermediate points. The feature is disabled if the value is set to 0.0.
||The renderable version of the tube.
