Abstract
We present a method for frame coherent texturing and hatching of 3D models with a discrete set of colors. Our technique is inspired by various artistic styles that use a limited set of colors to convey surface shape and texture. In previous research discrete color shading was produced by modifying smooth shading with a threshold function. We extend this approach and specify threshold values with an image or a procedural texture. Texture values and mapping coordinates are adapted to surface orientation and scale. Aliasing artifacts are eliminated by the modified filtering technique. The threshold texturing approach enables an animator to control local shading and to display surface roughness and curvature with a limited set of colors.
