Streamlines and timelines provide a snapshot of some flowfield characteristics, whereas streaklines and pathlines depend on the full time-history of the flow. However, often sequences of timelines (and streaklines) at different instants—being presented either in a single image or with a video stream—may be used to provide insight in the ...
Analytical methods that analyse a given flow and show properties like streamlines, streaklines, and pathlines. The flow can either be given in a finite representation or as a smooth function. Texture advection methods that "bend" textures (or images) according to the flow. As the image is always finite (the flow through could be given as a ...
File:Lagrangian vs Eulerian [further explanation needed] Eulerian perspective of fluid velocity versus Lagrangian depiction of strain.. In classical field theories, the Lagrangian specification of the flow field is a way of looking at fluid motion where the observer follows an individual fluid parcel as it moves through space and time.
Why not give the streamlines as initial-value ODEs like the streaklines and pathlines? Also, it might be stressed that pathlines are spatiotemporal lines while streamlines are only spatial lines. — Preceding unsigned comment added by 62.16.179.14 20:48, 7 August 2013 (UTC)

Methods for visualizing vector fields include glyphs (graphical icons) such as arrows, streamlines and streaklines, particle tracing, line integral convolution (LIC) and topological methods. Later, visualization techniques such as hyperstreamlines [7] were developed to visualize 2D and 3D tensor fields.
streaklines: the line produced by particles passing through a specific fixed point over various times; pathlines: showing the path that a given particle (of zero mass) would follow. streamlines (or fieldlines): the path of a particle influenced by the instantaneous field (i.e., the path of a particle if the field is held fixed). Magnetic fields.
In this reference frame, fluid parcels are labelled and followed through space and time. But also in the Eulerian frame of reference the notion of fluid parcels can be advantageous, for instance in defining the material derivative, streamlines, streaklines, and pathlines; or for determining the Stokes drift.
