“…One means by which to focus on a particular subset, area of interest, or feature of a flow field is via a streamline seeding strategy. In general, three popular streamline seeding strategies are often used: (1) image-based seeding strategies such as that described by Turk and Banks [17] or the evenly spaced-streamline seeding strategy presented by Jobard and Lefer [7], (2) topological or feature-based, seeding strategies such as those presented by Verma et al [21] or Sanna et al [13], or (3) interactive seeding strategies using a streamline seeding rake used by Bryson and Levit [2] or Schultz et al [15]. Our approach falls into the third category-an interactive streamline seeding strategy.…”

Figure 1: Visualization of swirl and tumble flow using a combination of direct color-mapping, streamlines, isosurfaces, texture-based flow visualization and slicing. (Left) visualizing swirl flow using 3D streamlines and texture-based flow visualization on an isosurface, (middle-left) a clipping plane is applied to reveal occluded flow structures, (middle-right) an isosurface and 3D streamlines visualize tumble motion, and (right) the addition of texture-based flow visualization on a color-mapped slice. ABSTRACTWe investigate two important, common fluid flow patterns from computational fluid dynamics (CFD) simulations, namely, swirl and tumble motion typical of automotive engines. We study and visualize swirl and tumble flow using three different flow visualization techniques: direct, geometric, and texture-based. When illustrating these methods side-by-side, we describe the relative strengths and weaknesses of each approach within a specific spatial dimension and across multiple spatial dimensions typical of an engineer's analysis. Our study is focused on steady-state flow. Based on this investigation we offer perspectives on where and when these techniques are best applied in order to visualize the behavior of swirl and tumble motion.

“…Another class of methods aim at automatically placing seed points throughout the domain in order to achieve an even distribution of the corresponding streamlines [44][45][46][47][48]. Following this approach, Sachse et al devised a new streamline seeding technique, specifically designed for the visualization of the electrical current, that distributes streamlines in the volume based on the local value of the current density [49,50].…”

This paper presents two new hardware-assisted rendering techniques developed for interactive visualization of the terascale data generated from numerical modeling of nextgeneration accelerator designs. The first technique, based on a hybrid rendering approach, makes possible interactive exploration of large-scale particle data from particle beam dynamics modeling. The second technique, based on a compact texture-enhanced representation, exploits the advanced features of commodity graphics cards to achieve perceptually effective visualization of the very dense and complex electromagnetic fields produced from the modeling of reflection and transmission properties of open structures in an accelerator design. Because of the collaborative nature of the overall accelerator modeling project, the visualization technology developed is for both desktop and remote visualization settings. We have tested the techniques using both timevarying particle data sets containing up to one billion particles per time step and electromagnetic field data sets with millions of mesh elements.
