Hello,

The tar file

  http://mathcs.holycross.edu/~ahwang/epix/tubes.tar

contains some comented code (tubes.h) and an xp file illustrating use.
If the files are in the same directory, compile with

  elaps -I. tubes2.xp

The tubes/vessels are 3-D objects; you can add arrows, etc., manually. (As 
usual, you have to arrange scene elements in reverse order of distance to 
the camera, if appropriate.)
