Illustrative volume visualization frequently employs non‐photorealistic rendering techniques
to enhance important features or to suppress unwanted details. However, it is difficult to …

In this article we survey techniques for the digital simulation of hand-made stippling—one of
the core techniques developed within non-photorealistic/expressive rendering. Over the …

In this paper, we survey illustrative rendering techniques for 3D surface models. We first
discuss the field of illustrative visualization in general and provide a new definition for this …

Integral surfaces are ideal tools to illustrate vector fields and fluid flow structures. However,
these surfaces can be visually complex and exhibit difficult geometric properties, owing to …

Pen-and-ink line drawing techniques are frequently used to depict form, tone, and texture in
artistic, technical, and scientific illustration. In non-photorealistic rendering (NPR) …

Most 3D vector field visualization techniques suffer from the problem of visual clutter, and it
remains a challenging task to effectively convey both directional and structural information of …

Nonphotorealistic rendering techniques, including line drawings, can be remarkably efficient
at conveying shape and meaning with a minimum of visual distraction. This class will …

We present a novel scheme for automatically generating line drawings from 2D images,
aiming to facilitate effective visual communication. In contrast to conventional edge …

Abstract Models of topography, such as smooth and non-smooth, single-sided and double-
sided, appear to be of value in choosing algorithms to calculate topographic attributes, and …

When people compare a computer-generated illustration to a hand-drawn illustration of the
same object, they usually perceive differences. This seems to indicate that the two kinds of …
