Fluid dynamics is the science that underlies the movement of liquids and gases. To study fluid flow, computationally expensive methods must be used to model the intricate and complex interactions of many molecules in a gas or liquid for applications such as air flow around an experimental aircraft or analyzing cloud formation. Scientists rely on visualization strategies to aid in interpreting the results of a complex fluids simulation. Current methods of creating visual feedback from flow simulations result in cluttered and hard to understand images.

Researchers at Purdue University have developed a new, interactive, volume rendering and visualization system for flows and volumes that stimulates and enhances traditional illustration, experimental advection, and photographic flow visualization techniques. A combination of varying styles is used to allow interactive visualization, explorations, and comparative analysis of scalar, vector, and time-varying volume datasets. This system produces effective reduction of visual clutter, the required utilization of only one-dimensional or two-dimensional oriented structural information, the ability to allow both spatially varying and data-varying specification of rendering styles, and the ability to interactively visualize, explore, and analyze scalar, vector, and time-varying volume datasets.

Advantages:
-Clearer, more concise image of 3-D flow datasets
-Compact and manageable parameters with interactive results
-Can work at interactive rates on modern PCs
-Reduces visual clutter
-Less expensive compared to flow photography process or manual sketch illustration process

Potential Applications:
-Analysis of scalar, vector, and time-varying volume datasets
