Semi-Three-Dimensional Visualization of Electromagnetic Field Analysis Result With Volumetric Display

When visualizing a 3-D electromagnetic field analysis result, physical quantity on a surface or a cross section of objects is visualized mostly. It is, however, desired to observe the physical quantity and the phenomenon inside the objects in 3-D space. In this paper, the method to visualize the physical quantity inside the objects with a volumetric display is proposed. The volumetric display is based on a stack of liquid crystal displays (LCDs), and developed to separately display the images on the LCDs. With the volumetric display, the physical quantity, which changes on different cross sections of the objects in 3-D, can be visualized simultaneously. The volumetric display is also used for image comparison. In order to compare the results of magnetic field analysis, usually each image is compared by overlappingly visualizing these. However, it is easy to visualize the images and compare these, using the volumetric display. The volumetric display is a useful tool for postprocessing of the electromagnetic field analysis.
