Loviscach, Jörn2015-11-122015-11-1220021017-4656https://doi.org/10.2312/egs.20021017Most commercial 3-D software packages used for animated films and still picture production offer merely rudimentary support for non-photorealistic rendering. However, nearly all of these packages possess interfaces which allow the user to add custom shader programs. We present a solution which uses a custom shader combined with post-processing software in order to draw outlines and creases of 3-D scenes in a way which simulates artistic tools like pencils and ink brushes.
