Load the supernova explosion velocity field from "supernova-velocity_isosurface/data/supernova-velocity_isosurface.vti" (VTI format, 128x128x128). Extract an isosurface of velocity magnitude at threshold 0.7. Color the isosurface by the vz component using 'Blue to Red Rainbow' colormap. Add a color bar labeled 'Vz Component'. Dark background (RGB: 0.0, 0.0, 0.0). Isometric camera view. Render at 1024x1024. Save the paraview state as "supernova-velocity_isosurface/results/{agent_mode}/supernova-velocity_isosurface.pvsm". Save the visualization image as "supernova-velocity_isosurface/results/{agent_mode}/supernova-velocity_isosurface.png". (Optional, if use python script) Save the python script as "supernova-velocity_isosurface/results/{agent_mode}/supernova-velocity_isosurface.py". Do not save any other files, and always save the visualization image.
