| Sumario: | Non-photorealistic rendering can be used to create abstracted images of real-life objects. Cross-hatching is a common style under the non-photorealisticrendering umbrella, where characteristics such as lighting and shape of objectsare represented by layered patches of parallel lines.The work in this master thesis explores the creation of cross-hatched ren-ders where lighting and shape can be implied by density and direction of thehatching lines. We choose to place the hatching lines following the curvaturecharacteristics of the object. For this purpose, we describe a way to computeand interpolate principal curvature directions and an image-space algorithm todraw lines following such directions. |
