The results of this experience are three technical contributions targeted at an NPR (Non-Photorealistic Rendering) research audience. The first is a formal definition of hatching, a traditional drawing technique. The second is the "hatching shape," a software primitive for rapidly performing hatching. The third is the invented problem of "mashing up" two drawings, along with an algorithm for solving this problem. In addition to these technical contributions, I relate how researching NPR changed me as an artist.enline artnprexpressive renderingnon-photorealistic renderingillustrationhatchinghuman-centered computingDoctoral Thesis
