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 …

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) …

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 …

Homomorphic filtering (HF) is a methodology that separates an image into two components:
illumination and reflectance. Through the processing of these components, it is possible to …

Object recognition and tracking are two of the most dynamic research sub-areas that belong
to the field of Computer Vision. Computer vision is one of the most active research fields that …

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

While 3D line drawing techniques have become well established in the past decade, most
are only suitable for polygonal meshes. This paper presents splatting lines, a unified …

Sketch-drawing is one of the simplest and most direct means to illustrate 3-D objects. It can
not only present geometric features, but also greatly facilitate us to identify and understand …

Immersive technology may offer novel user interaction modalities to manipulate and design
spacecraft trajectories within complex dynamical environments. This paper presents an …

We present a novel line drawing approach for 3D models by introducing their skeleton
information into the rendering process. Based on the silhouettes of the input 3D models, we …
