AUFLIC Flow-Driven Seeding Strategy Key Points Spatial flexibility arbitrary position with a pixel (not necessarily the center) Temporal flexibility within a small fractional time shortly after the SCAP begins Spatially-evenly Pathline sampling convolution is simplified to averaging Fourth-order Runge-Kutta integrator with adaptive step-size and error control Cubic Hermite polynomial interpolation If possible, seeds (S) are released at some sample points along an available pathline (seed S 0 ) at the same time as S 0 passes through these sample points only a small number of seeds need to actually advect pathlines a significant number of seeds extract pathlines by pathline copying & pathline reuse Pathline copying intra- SCAP operation S and S 0 are released in the same SCAP Pathline reuse inter- SCAP operation S and S 0 are released in different SCAPs A relatively-continuous, flow-structure based seeding strategy to replace the intermittent ( only at integer time steps ), pixel-center based scheme of UFLIC High temporal-spatial coherence is maintained due to a still dense value scattering coverage
