Abstract:
In this paper we present an efficient approach to cartoon
style rendering of an image with an approximated crayon
texture. The algorithm generates a crayon texture map,
with two crayon textures (illuminated color texture and
shadowed color texture) combined into one. The crayon
texture is generated using crayon stroke generation
technique. The texture is then mapped onto the image in
cartoon style using per-vertex mapping concept. This
algorithm results in an improved transition boundary
between the two texture colors, comparable to the normal
cartoon shaded image without crayon texture. If the image
generated by this algorithm is animated, then the
transition boundary would move logically with the object
as compared to our earlier algorithm (described in the
text), where transition boundary changed drastically with
slight movement of an object in the image. The present
approach can be used to generate variations in cartoon
shading easily and efficiently. We have also attempted to
approximate the effect of distribution of wax in the
resulting image.
