Visualising two-dimensional vector fields using directed halftone cells (original) (raw)

AI-generated Abstract
Digital halftoning is a technique for converting an image with multiple levels of grey into a bi-level (bitmap) image, typically in preparation for printing on paper. It is standard practice to 'optimize' the halftoning process to reduce visibility of artifacts that appear as textures within a region of uniform or slowly varying intensity. A method is presented for modifying the halftoning process to visualize two-dimensional vector fields, indicating field direction through texture and field magnitude through intensity. This method offers rapid visualization suitable for laser printing and bitmapped displays and is effective for measuring electromagnetic and flow fields.
