In this paper, we introduce a new direct volume rendering (DVR) algorithm for multi-view auto-stereoscopic displays. Common multi-view methods perform multi-pass rendering (one pass for each view) and subsequent image compositing and masking for generating multiple views. The rendering time increases therefore linearly with the number of views, but sufficient frame-rates are achieved by sub-res...

Interactive volume rendering for data set sizes larger than one million samples requires either dedicated hardware, such as three-dimensional texture mapping, or a sparse representation and rendering algorithm. Consumer graphics cards have seen a rapid explosion of performance and capabilities over the past few years. This paper presents a splatting algorithm for direct volume rendering that ut...

We propose a new model for visualization of high scale scenes. It is designed to enhance pertinent informations that become quickly viewable on a large scene. It consists in mixing different kind of rendering techniques in the same frame. This method is achieved in real-time during the rendering process using GPU programming. Moreover rendering techniques used and key points defined by the user...

Landscapes have been the main theme in Chinese painting for over one thousand years. Chinese ink painting is a form of nonphotorealistic rendering. Terrain is the major subject in Chinese landscape painting, and surface wrinkles are important in conveying the orientation of mountains and contributing to the atmosphere. Over the centuries, masters of Chinese landscape painting have developed var...

Non-photorealistic rendering (NPR) algorithms are used to produce stylized images, and have generally been evaluated on the aesthetic qualities of the resulting images. NPR-produced images have been used for aesthetic and practical reasons in media intended to produce an emotional reaction in a consumer (e.g., computer games, films, advertisements, and web sites); however, it is not understood ...

virtual reality, developing techniques for synthesizing arbitrary views has become an important technical issue. Given an object’s structural model (such as a polygon or volume model), it’s relatively easy to synthesize arbitrary views. Generating a structural model of an object, however, isn’t necessarily easy. For this reason, research has been progressing on a technique called image-based mo...

Medical illustrations use simple drawing styles to demonstrate shapes and features of organs and organ systems, while omitting irrelevant details. In this contribution, we present a non-photorealistic rendering algorithm for illustrating anatomical data. Unlike other existing methods that rely on available triangulations of the organs to be rendered, our approach relies only on a subset of surf...

SARA is an ongoing research project that investigates in a novel and artistic way the causes for social communication and emotion recognition deficits in children and adolescents with high-functioning autism spectrum disorders (ASD). The novelty of our work resides in the real-time generation and parameterization of emotional facial expressions of virtual characters by means of speed, intensity...

Applying non-photorealistic rendering techniques to stylise portraits needs to be done with care, as facial artifacts are particularly disagreeable. This paper describes a technique for watercolour rendering that uses a facial model to preserve distinctive facial characteristics and reduce unpleasing distortions of the face, while maintaining abstraction and stylisation of the overall image, em...
