Texture-based methods

Definition

Texture-based methods refer to techniques used in the visualization and post-processing of data that emphasize the surface characteristics of a flow field. These methods enhance the representation of complex flow structures, allowing for a better understanding of phenomena such as turbulence and boundary layers by visually distinguishing different regions based on texture variations. By applying these techniques, researchers can gain insights into fluid dynamics that may not be immediately apparent through traditional visualization approaches.
