  abstract = {We present Q-mapping which is a technique for rendering
              three-dimensional objects using nonphotorealistic cues, by
              applying Q-maps. Q-maps are three-dimensional textures that make
              marks on objects, and thus provide visual cues for shape, shade,
              and texture. Q-maps adapt to light intensity, typically by making
              more marks in darker areas. Q-maps can produce images with a very
              wide range of visual styles (e.g. half tone shading, and
              pen-and-ink colour wash). The primary contribution is that these
              styles reside in a single parametric space. Importantly this space
              includes photorealism as a style, which is therefore regarded as a
              special case of nonphotorealistic image rendering in general. We
              illustrate our explanation of Q-mapping using examples from
              scientific visualisation and computer graphics - and provide a
              gallery of images to show the versatility of the approach.},
