Particle tracing based techniques use point-shaped geometry to trace out paths through the vector field. Portions of the field are seeded with particles and paths are traced through the field following the vector field samples. The positions of the particles along their respective paths are animated over time to convey a sense of flow through the field. A variation on the techniques is to trace out the paths and display each path as a stream line using lines, ribbons or tubed shaped geometry.
