Below are some examples of non-photorealistic shading made with the EVA renderer and the Expressive Effects plugins for Maya. In all but two cases the images were rendered directly from 3D geometry. The pig and straw hat pictures result from 2D image filters. Most of the effects are frame-to-frame coherent, meaning they animate smoothly. A few animated examples can be seen on the Non-photorealistic Animation Gallery page.
