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.
