Trajectory actor, together with a transfer function.

The trajectory actor draws Lagrangian particle trajectories (path lines) or streamlines into a scene, either as 3D tubes or as particle positions.

• Supports precomputed particle trajectories that are available in a file format similar to NetCDF-CF. Currently, a converter is available for LAGRANTO trajectories (please contact us).
• Trajectories can be drawn as 3D tubes, coloured by pressure elevation and (new in Met.3D 1.7) any other variable that has been traced/sampled along the trajectory.
• Shadows of the trajectories are rendered to the surface.
• The individual positions of the trajectory particles can also be drawn, either for the entire trajectories or for individual time steps.
• Animations of particle positions are possible. Also, trajectory tubes can be drawn for the part of the trajectory between trajectory start and current time.
