The use of textures provides a rich and diverse set of possibilities for the visualization of flow data. In this paper, we present methods designed to produce oriented and controlled textures that accurately reflect the complex patterns that occur in vector field visualizations. We offer new insights based on the specification and classification of neighborhood models for synthesizing a texture that accurately depicts a vector field. Secondly, we introduce a computationally efficient method of texture mapping streamlines utilizing outlining textures to depict flow orientation.
