(n) Line marks, usually curved, used in visualizations to depict the path of flow of a fluid or gas Streamlines are used in aerodynamic studies to evaluate the flow of air or water around a proposed design
A method for outlining the topology, i e the field lines, of a vector field One takes a set of starting points, finds the vectors at these points by interpolation, if necessary, and integrates the points along the direction of the vector At the new positions the vector values are found by interpolation and one integrates again This process stops if a predetermined number of integration steps has been reached or if the points end up outside the data volume The calculated points are connected by lines The streamlines technique considers the vector field to be static
