In the field of laser simulation, Visualization of intensity data is a very important work. The laser intensity data is characterized by scattered volumetric data and does not have relation information between each data. We used an iso-surface, a representative indirect volume rendering method, as a method to analyze the geometric characteristics of the intensity data. However, iso-surface visualization requires the proper choice of an iso-value. If you determine the iso-value in a fully interactive manner without any guidance, then the value will not be what you want most. Hence, most visualization tools involve preprocessing that analyzes the values and calculates the appropriate iso-value, but this method is not suitable for laser intensity data, which is the scattered volume data. To solve this problem, we divide the whole grid, and calculate the weights for the specific areas to derive the appropriate iso-value that the user wants.
Particle accelerator has mainly used in nuclear field only because of the large scale of facility. However, since laser-plasma particle accelerator, which has smaller size and spends less cost, developed, the availability of this accelerator is expended to various research fields such as industrial and medical. In these, real-time and interactive applications, accelerating the compute time is a critical problem. We conduct a simulation discussed the method of visualization of multivariate data in three dimensional space by using colored volume rendering and surface rendering. This system offers real-time 3D images via convert various file format comes from PIC simulation into OpenGL texture type to analyze and modify plasma data. We also suggest new method to visualize plasma data by using alpha shape to achieve a different level of detail for the given plasma based particle acceleration data. Many scientists are not familiar with the concepts of programming languages. Therefore, we employ the visual- scripting engine to define the rendering context of plasma physics.
It costs high in both memory usage and time consuming to sample the space to compute charge density and calculate electric field on that with large size of plasma data. In real-time and interactive application, accelerating the compute time is critical problem. In this paper, we suggest new method to visualize electric field by using convolution theorem, and the parallel computing to accelerate computing time by using GPGPU. We conduct a simulation that compare running time between the methods with convolution and without convolution. We discussed the method of visualization of multivariate data in three dimensional space using colored volume rendering and surface construction.
