This paper presents a non-photorealistic rendering technique that automatically generates a
line drawing from a photograph. We aim at extracting a set of coherent, smooth, and stylistic …

This tutorial describes the geometry and algorithms for generating line drawings from 3D
models, focusing on occluding contours. The geometry of occluding contours on meshes …

Three-dimensional shape can be drawn using a variety of feature lines, but none of the
current definitions alone seem to capture all visually-relevant lines. We introduce a new …

We present a non-photorealistic rendering technique that automatically delivers a stylized
abstraction of a photograph. Our approach is based on shape/color filtering guided by a …

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 …

This article introduces a programmable approach to nonphotorealistic line drawings from 3D
models, inspired by programmable shaders in traditional rendering. This approach relies on …

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) …

This paper introduces a programmable approach to non-photorealistic line drawing from 3D
models, inspired by programmable shaders in traditional rendering. We propose a new …

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

This paper presents an approach for determining stroke thickness in computer-generated
illustrations of smooth surfaces. We assume that dark strokes are drawn to approximate the …
