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 …

Visual Computing for Medicine, Second Edition, offers cutting-edge visualization techniques
and their applications in medical diagnosis, education, and treatment. The book includes …

Sketch-based 3D shape retrieval has become an important research topic in content-based
3D object retrieval. To foster this research area, two Shape Retrieval Contest (SHREC) …

Curves on objects can convey the inherent features of the shape. This paper defines a new
class of view-independent curves, denoted demarcating curves. In a nutshell, demarcating …

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 …

Over the last few years, researchers in computer graphics have developed sophisticated
mathematical descriptions of lines on 3D shapes that can be rendered convincingly as …

Edge detection in images has been a fundamental problem in computer vision from its early
days. Edge detection on surfaces, on the other hand, has received much less attention. The …

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 novel techniques for visualizing, illustrating, analyzing, and generating carvings
in surfaces. In particular, we consider the carvings in the plaster of the cloister of the …

Incorrect spatial interpretation of 3D vascular models is a main perceptional problem in
medical visualization. For improved depth perception, we propose supporting anchors …
