Abstract:
In the field of computer-generated line drawings, line direction is among the most critical factors for conveying surface shape. Principal direction line drawings generated from volume data inspired us to target the widely-used polygonal surface representations. We use the principal directions of curvature to guide the lines over an arbitrarily curved 3D surface. The resulting line drawings are viewpoint independent and can be rendered in real-time.
