Now the advanced visual simulation system is usually equipped with the large-wide projection or multi-projection display system, and several graphic workstations to achieve the real-time rendering task for multiple channels, which can provide the large field of view for user and bring the immersive feeling with the interactive devices' supporting. This paper presented a novel multi-channel visual...
Particle-based models are widespread in the field of computer graphics and are mostly used in soft-body dynamics, for simulating surfaces such as cloth, fluids and biologic tissue. As model resolution and scenario complexity increases, the computation required for these particular applications becomes overwhelming for a single processing unit, especially when interactivity is required, thus parallelization...
The 2D to 3D conversion technique plays an important role in the development and promotion of three-dimensional television (3DTV), because it can provide adequate supply of high-quality 3D program content. This Paper focuses on the real-time implementation of 2D-3D system, of which the major parts are source depth-map generation and depth image-based rendering (DIBR). The depth-map is generated by...
Most Virtual Reality (VR) applications use rendering methods which implement local illumination models, simulating only direct interaction of light with 3D objects. They do not take into account the energy exchange between the objects themselves, making the resulting images look non-optimal. The main reason for this is the simulation of global illumination having a high computational complexity, decreasing...
This paper describes a prototype, the Visualized Architecture Knowledge Management Collaboration Services (VAKMCS), used for accessing and interacting with architecture knowledge to make effective implementation decisions on Information Systems used in enterprises. The tool incorporates the concepts of architecture knowledge and rationale while adding support for visualization and collaboration through...
Cellular signal transduction involves a transport step from the plasma membrane towards the nucleus, during which the signaling molecules are partly deactivated in control loops. This leads to a gradient in the concentration of active signaling molecules. The low number of molecules introduces spatio-temporal fluctuations and the asymmetric cellular architecture further increases the complexity. We...
Smart environments consist of several interconnected devices. The device ensemble can change dynamically as mobile devices enter or leave the environment. To utilize such environments efficiently for information visualization, we propose a service-oriented architecture.Various services run on different machines and visualizations are generated dynamically depending on the environment's current situation...
We present a new method for the combined visualization of software architecture diagrams, such as UML class diagrams or component diagrams, and software metrics defined on groups of diagram elements. Our method extends an existing rendering technique for the so-called areas of interest in system architecture diagrams to visualize several metrics, possibly having missing values, defined on overlapping...
This paper presents a generic software architecture developed to allow users located at different physical locations to share the same virtual environment and to interact with each other and the environment in a coherent and transparent manner.
Visualization, interaction, and simulation (VIS) constitute a class of applications that is growing in importance. This class includes applications such as graphics rendering, video encoding, simulation, and computer vision. These applications are ideally suited for accelerators because of their parallelizability and demand for high throughput. We compile a benchmark suite, VIS- Bench, to serve as...
This article consists of a collection of slides from the author's conference presentation. Some of the topics discussed include: Architecture Convergence; Larrabee Architecture; and Graphics Pipeline.
This paper describes the first use of a network processing unit (NPU) to perform hardware-based image composition in a distributed rendering system. The image composition step is a notorious bottleneck in a clustered rendering system. Furthermore, image compositing algorithms do not necessarily scale as data size and number of nodes increase. Previous researchers have addressed the composition problem...
