Parallelization of Particle Based Volume Rendering on Tiled Display Wall

In this paper we present a parallelized particle-based volume rendering (PBVR) system to obtain super linear speedup, i.e. the speedup with N processors is greater than N, on a distributed computing system. PBVR is a technique of volume rendering which does not need any sorting therefore it is suitable for parallel execution. We implemented the parallel version by using Open CABIN middleware and measured the performance. We confirmed that the parallelized PBVR is 1.5 to 8 times faster than the serial version.

Fusion Visualization System as an Open Science Foundation

This is an introduction paper of a project named the same as the title which is supported by Japan Science and Technology Agency. We plan to develop an interactive visualization system with both volume and surface rendering and big data analysis functions. It is for two years project that started at April 1st in 2016. Integrating 1D, 2D and 3D visualization tools, we aim to provide a new post processing tool that assists to reveal a causal relationship between variables among big data. This paper introduces the basic concept and the fundamental visualization technologies implemented in the system.

Data Reduction by Applying an Image-Based Modeling and Rendering Technique to CG Models

We applied an image-based modeling and rendering technique to reduce the data size of a CG model to be obtained as a visualization result. To date, this technique has been applied to the reconstruction of 3D graphical models from real objects; the size of the models can be reduced effectively because both color information and geometric information can be reduced. We applied a silhouette-and-voxel method that does not require design data for geometric simplification. Using our system, we simplified two models, one of which, involving medical data, was reduced by about 85% in file size. An accompanying subjective quality test showed that our approach maintains approximately the same visual quality as the geometric simplification method traditionally used.

Server System of Converting from Surface Model to Point Model

Handling the 3D CG model as a point clouds uniformly, it will be possible to easily perform data conversion, 3D shape search, and data downsizing. We have developed a system to convert a surface model to a point model and a system to downsize the point model. Then in order to publish these tools, we are currently proceeding to release these software as a service. In this paper, we introduce the service system.

Development of Integrated Visual Analytic Tool with 3D Visualization.

This is an interim report of a project to develop a new type of visualization system which integrates the conventional 3D visualization with data analysis tools such as parallel coordinates plot, correlation diagram and correlation matrix map. In this paper, we introduce the key functions and the usage. Through the interview to the potential customers, we learned that the collaboration of visualization and data analysis bring us a new data extraction ways but the design is suitable for observation based studies but not to some simulation studies.

Parallelized fusion visualization system

The speed-up of supercomputers has increased the complexity of simulations. To analyze such kind of data, we believe that new types of visualization software are needed. Therefore, we have been developing a visualization system called “Fusion Visualization”, and the progresses were reported in the AROB 18th and 19th International Symposiums. We introduced the overall concept at the AROB 18th International Symposium, and then demonstrated a sample of flow visualization in a blood vessel in the AROB 19th International Symposium. To extend our system to enable the handling of larger data, we have implemented the proposed system on a parallelized visualization system; AVS/Express PCE (Parallel Cluster Edition). This paper describes the implementation and the benchmark results.

An Introduction of Large Screen Stereo Viewer by PC cluster system

I introduce two 3D stereo viewing systems. One is for the large screen stereo system by cluster Pc system. The other one is the 3D stereo glass system that requires no power and no special CRT. It is available everywhere. The printed image can be seen in stereo by only the 3D glass. Im expecting that the system expands the 3D Viewing market.
