We present in this paper a new particle-based method for sampling and rendering several types of the nonphotorealistic feature contours on implicit surfaces: silhouette, shadow and suggestive contours. We introduce a curve adhesion behavior for dynamic particles that brings up the possibility to render any contour that is defined as an intersection of two smooth implicit surfaces. In the case o...

The nonphotorealistic rendering is recognized as one of the major topics in the recent computer graphics society. The general issue in this research area is achieving methods for imitating the artists’ rendering styles, such as oil-paintings, technical illustration, etc. The painterly rendering is one of the nonphotorealstic rendering methods dealing with the effects as the oil-paintings. It is...

This paper describes how technical illustrations containing opaque and non-opaque objects can be automatically generated. Traditional methods to show transparency in manual drawings are evaluated to extract a small and effective set of rules for computer-based rendering of technical illustrations, leading to a novel view-dependent transparency model. We propose a hardware-accelerated depth sort...

DesignScript, as the name suggests, is positioned at the intersection of design and programming. DesignScript can be viewed as part of the continuing tradition of the development of parametric and associative modeling tools for advanced architectural design and building engineering. Much of the thought processes that contribute to the effective use of DesignScript builds on the tradition of par...

Zurich where he became 'privat-dozent' for neurology, the first appointment of its kind in Switzerland. The following year in a borrowed room in the Pathological Institute, von Monakow assisted by a young American zoologist, Henry Donaldson, established the laboratory which was to become the Hirnanatomisches Institute. Von Monakow developed a very active private practice, first as a general phy...

In this paper we describe non-photorealistic rendering techniques for volumetric data sets. First, we outline an automatic approach that generates line drawings to illustrate such data sets and to augment traditional volume rendering techniques. For a number of seed points that are placed appropriately to represent selected volume structures curvature lines are traced and encoded by a sparse se...

In this research project, I focus on transnationalism through trans-Pacific migratory processes and its implications on the evolution of identity in Hong Kong families in Vancouver, Canada. Under the system of reference of social and cultural geography, three main parts are discussed: a conceptual one presenting surrounding aspects of transnationalism and its underlying concepts of identity, pe...

We introduce a novel volume illustration technique for regularly sampled volume datasets. The fundamental difference between previous volume illustration algorithms and ours is that our results are shape-aware, as they depend not only on the rendering styles, but also the shape styles. We propose a new data structure that is derived from the input volume and consists of a distance volume and a ...
