A path is a set of nodes that can be connected with each other or not. Once rendered in 3D, the path will appear as a tubular structure resembling a tree that traverses all the connected nodes.

These nodes can be distributed within the same slice or in different slices, thus allowing the path to span multiple slices along the Z axis.

Each node defines its diameter which in turn defines the section of the path at that given point.

BioVis3D uses the icon   to represent paths.
