Traditional computer graphics uses three-dimensional models to synthesise photorealistic images. But photorealism is just one rendering style amongst many. We invented “Q-mapping”,  which is a generalised form of cross hatching shading. Q-mapping is a procedural texture that maps painting cues onto objects, and works on polygonal data, on volumes, and even on video.  Q-mapping fits easily into the rendering pipeline, it can be used for scientific visualisation, and has been used by animation company Nanomation. All textures (expect the writing)  in this gallery are drawn with Q-maps.
