Abstract:
This research contributes two approaches for pen-and-ink stroke extraction and stylization from 3D polygonal meshes. The pen-and-ink medium is commonly used by artists to highlight shape and form of objects. The first approach presents a general solution to remove errors from silhouettes extracted from polygonal meshes in object space. This approach uses reverse-subdivision multiresolution to remove errors and perform automatic smoothing stylization on silhouette strokes. The second approach creates accurate, technical pen-and-ink styles using an edge-based approach. Ink is placed using edge-based shape measures generalized from geomorphology and controlled by a user-driven interface. The focus of this work is to provide a user with high-level interactive control of ink placement, while automatically generating individual strokes.
