The ubiquity of computer-generated imagery around us, in movies, advertising or on the
Internet is already being taken for granted and what impresses most people is the …

Even as developments in photorealistic computer graphics continue to affect our work and
leisure activities, practitioners and researchers are devoting more and more attention to non …

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 …

Drawing surfaces using hatching strokes simultaneously conveys material, tone, and form.
We present a real-time system for non-photorealistic rendering of hatching strokes over …

Ab stract Researchers in nonphotorealistic rendering (NPR) have investigated a variety of
techniques to simulate the styles of artists. Recent work has resulted in methods for pen-and …

Photorealism is one of the most quoted aspects of nowadays games. However, realistic
game graphics is not the only style desirable. This paper surveys the many graphical styles …

We propose a new system to produce pencil drawing from natural images. The results
contain various natural strokes and patterns, and are structurally representative. They are …

We present a semantics-driven approach for stroke-based painterly rendering, based on
recent image parsing techniques [Tu et al. 2005; Tu and Zhu 2006] in computer vision …

We present a method that takes a raster image as input and produces a painting-like image
composed of strokes rather than pixels. Our method works by first segmenting the image into …

Video sequences contain many cues that may be used to segment objects in them, such as
color, gradient, color adjacency, shape, temporal coherence, camera and object motion, and …
