main/supernova-velocity_pathline/task_description.txt

Load the supernova explosion velocity field time series from "supernova-velocity_pathline/data/supernova-velocity_pathline_{timestep}.vti", where "timestep" in {0000, 0005, 0010, 0015, 0020} (5 timesteps, VTI format, 128x128x128 grid each). 
Visualize the temporal evolution of flow patterns by generating streamlines from each timestep and overlaying them. 
Seed 50 particles from a spherical shell centered at (64, 64, 64) with radius 20 (near the explosion center). 
For each timestep, trace streamlines in the forward direction with maximum length 80. 
Render streamlines as tubes with radius 0.25. Color each timestep differently to show temporal progression (blue for t=0 through red for t=20). 
Also include a magnitude-colored version using the 'Turbo' colormap for the final timestep. 
Add a color bar labeled 'Velocity Magnitude'. Use a dark background (RGB: 0.02, 0.0, 0.04). Set an isometric camera view. Render at 1024x1024 resolution.
Save the paraview state as "supernova-velocity_pathline/results/{agent_mode}/supernova-velocity_pathline.pvsm".
Save the visualization image as "supernova-velocity_pathline/results/{agent_mode}/supernova-velocity_pathline.png".
(Optional, if use python script) Save the python script as "supernova-velocity_pathline/results/{agent_mode}/supernova-velocity_pathline.py".
Do not save any other files, and always save the visualization image.
