Studies in Comparative Visualization of Flow Features

This chapter introduces two important concepts: feature visualization and comparative visualization. Features are patterns or structures hidden in complex data describing physical phenomena. Comparative visualization is concerned with the analysis of differences and sources of error in a simulation or visualization process. Using examples from fluid dynamics, different types of comparative visualization of flow features are illustrated and analysed. Feature extraction techniques for vortices, shock waves, and skin friction are described, and comparative analysis shows their strengths and weaknesses. Some important lessons may be learned from these examples. Comparative visualization is identified as an important tool for data exploration, which provides incentives for explanations and further investigations, and increases awareness of possible problems within the visualization process itself.
