In recent years, several techniques have been proposed for automatically producing line-art illustrations. In this paper a new non photo-realistic rendering scheme for triangulated surfaces is presented. In contrast to prior approaches with parametric surfaces, there is no global parameterization for triangle meshes. So a new approach is made to automatically generate a direction field for the ...

An artistic rendering method of free-form surfaces with the aid of half-toned text that is laid-out on the given surface is presented. The layout of the text is computed using symbolic composition of the free-form parametric surface S(u, v) with cubic or linear Bézier curve segments C(t) = {cu(t), cv(t)}, comprising the outline of the text symbols. Once the layout is constructed on the surface,...

We present a novel framework for non-photorealistic rendering (NPR) based on view-dependent geometric simplification techniques. Following a common thread in NPR research, we represent the model as a system of particles, which will be rendered as strokes in the final image and which may optionally overlay a polygonal surface. Our primary contribution is the use of a hierarchical view-dependent ...

Conventional marketing wisdom holds that a customer orientation provides a firm with a better understanding of its customers, which subsequently leads to enhanced customer satisfaction and firm performance. However, there are cautions that being too customer focused can lead to inertia, and anecdotal evidence suggests that it may be better to "ignore your customer" when developing new products....

The purpose of the present study was to extend knowledge on the relationship between athletic identity and achievement goal orientations. In addition, the present study investigated the impact of independent variables, such as sport divisions and the type of sports gymnastics on the formation of athletic identity. Participants were 140 boys and girls athletes ranging from 8 to 17 years of age (...

Prior research indicates that East Asians are more sensitive to contextual information than Westerners. This article explored aesthetics to examine whether cultural variations were observable in art and photography. Study 1 analyzed traditional artistic styles using archival data in representative museums. Study 2 investigated how contemporary East Asians and Westerners draw landscape pictures ...

Stippling is an artistic rendering technique where shading and texture is given by placing points or stipples on the canvas until the desired darkness is achieved. Computergenerated stippling has focused on producing high quality 2D renditions for print media, while stippling of 3D models in animations has received little attention. After describing current advances in stippling for print media...

The Prinzhorn Collection preserves and exhibits thousands of visual artworks by patients who were diagnosed to suffer from mental disease. From this collection, we analyzed 1,256 images by 14 artists who were diagnosed with dementia praecox or schizophrenia. Six objective statistical properties that have been used previously to characterize visually aesthetic images were calculated. These prope...

This issue presents a snapshot of Musical Research at Ircam between 2008 and 2011, following the very first issue of this journal in 1984 on Musical Thought at IRCAM (Tod Machover, Editor). Within this time span, whereas the role of Ircam as an institution dedicated to scientific research for artistic creativity has remained unchanged, the context of such innovative endeavors, the role of the i...

This paper presents an artistic rendering system for generating 3D images of Chinese paintings using graphics hardware. The user can adjust suitable parameters flexibly to generate different brush styles as his/her hobby, and see rendering results in real time. In this system, we propose a hardware-accelerated method to draw Chinese painting strokes efficiently along visible silhouettes. Three-...
