WebDec 21, 2024 · New objects can also be generated. These include streamlines and stream surfaces or tubes, vortex lines and vortex tubes, particles and their trajectories, streaklines, and material lines or surfaces. The third step is the generation of objects that will be rendered in the next step. WebStreamlines and pathlines represent valuable tools for flow visualization. It is easier, however, to inject some tracer at a certain location of the flow field, and observe the pattern thus created. The locus of all fluid particles that have previously passed through a common point is called a streakline.
