-            - <em>tube</em> A ForceField which exerts force only in the direction it is oriented. The force is only exerted on objects that are in a tube of length <em>length</em> and diameter <em>diameter</em>. The magintude of the force is proportional to the <em>velocity</em>, being highest when an object is in the middle of the tube (radius-wise), linearly decreasing with greater radii and finally reaching zero, when the object is <code>diameter/2</code> away from the orientation vector.
+            - <em>tube</em> A ForceField which exerts force only in the direction it is oriented. The force is only exerted on objects that are in a tube of length <em>length</em> and diameter <em>diameter</em> (with rounded start and end faces, so in fact the <em>length</em> parameter specifies a ball with <code>origin + length/2</code> as the center and <code>length/2</code> as the radius). The magintude of the force is proportional to the <em>velocity</em>, being highest when an object is in the middle of the tube (radius-wise), linearly decreasing with greater radii and finally reaching zero, when the object is <code>diameter/2</code> away from the orientation vector.
             - <em>sphere</em> A Force Field which exerts force radially away from itself, with the greatest magnitude (proportional to <em>velocity</em>) being in the origin of the ForceField, linearly decreasing with respect to the distance to the origin and finally reaching zero at distance <code>diameter/2</code>.
             Default is <em>tube</em>.
