Rendering of photo-realistic images at interactive frame rates is currently an extensively researched area of computer graphics. Many of these approaches attempt to utilize the computational power of modern graphics hardware for ray tracing based methods. When using path tracing algorithms the ray paths are highly incoherent, hence we propose an efficient technique that minimizes the divergence...

In this paper we present a logical language for representing and reasoning about drawings in the context of interactive computer graphics. We discuss the motivation for this kind of representation in graphics systems and its applications to geometric reasoning and constraint satisfaction. A formal deenition of the language and its interpretation process is presented and illustrated. The theoret...

Recent research has shown that scalable, high-performance graphics systems may be built from commodity graphics hardware running on clusters. The rendered images are then displayed on nodes directly connected to the local system area network. However, many application scenarios require remote display across low speed networks. In this paper we describe a remote, image-based, display system for ...

Digital interactive media augments interactive computing with video, audio, computer graphics and text, allowing multimedia presentations to be individually and dynamically tailored to the user. Multimedia, and particularly continuous media pose interesting problems for system designers, including those of latency and synchronization. These problems are especially evident when multimedia data i...

Shading and classification are among the most powerful and important techniques used in volume rendering. Unfortunately, for hardware accelerated volume rendering based on OpenGL, direct classification is only supported on SGI platforms and shading could previously only be approximated inaccurately, resulting in shading artifacts mostly visible in darkening artifacts. So far, the combination of...

Rendering realistic moving water is one of the key techniques that immerse the viewers into interactive graphics world including computer games. Physical simulations based on computational fluid dynamics (CFD) is useful for rendering the realistic behaviour of water. However, real-time fluid rendering has been one of the challenging tasks because of high computational cost of CFD. According to ...

Graph algorithms are fundamental to many fields including operations research, physically based simulation, mechanics, logistics management, and sensor networks. In this talk, we will celebrate a few graph algorithms that have helped us make significant progress in geometry processing for graphics applications. Since the time graphs were used only for representations such as the tree representa...

This thesis examines interactive computer graphics and biomechanical engineering analysis as components in a computer simulation system for planning plastic surgeries. A new synthesis of plastic surgery planning techniques is proposed based on a task-level analysis of the problem. The medical goals, procedures, and current planning techniques for plastic surgery are reviewed, and from this a li...
