1) Time-varying vector field handling (256x128x128 grid), Streamline generation from line seed for each timestep
2) Line seed along z-axis at x=128, y=64, 50 seed points from z=20 to z=108
3) Bidirectional tracing with max length 150, Tube rendering with radius 0.5
4) Spectral color-coded temporal progression
5) Spectral colormap for magnitude, Color bar with label 'Velocity Magnitude'
6) Dark background (RGB: 0.0, 0.0, 0.02), Oblique camera view (azimuth 45, elevation 20), Output resolution 1024x1024
