Volume data are widely used in many areas, especially in biomedical science and geology. Visualizing volume data is very important to enable intuitive understanding of 3D structures, making them easier to analyze. However, current visualization technologies for volume data cannot satisfy human requirements. In this study, we propose a holographic display method for volume data by volume rendering. Based on this holographic display method, we can generate holograms for transparent objects and multi-layer objects. In this paper, to increase the speed of calculation, we propose an approximate volume rendering based CGH calculation method with elemental holograms.
