Rendering realistic moving water is one of the key techniques that immerse the viewers into interactive graphics world including computer games. Physical simulations based on computational fluid dynamics (CFD) is useful for rendering the realistic behaviour of water. However, real-time fluid rendering has been one of the challenging tasks because of high(More)
Hospital information systems (HIS) have turned a hospital into a gigantic computer with huge computational power, huge storage, and wired/wireless local area network. On the other hand, a modern medical device, such as echograph, is a computer system with several functional units connected by an internal network named a bus. Therefore, we can embed such a(More)
For presenting virtual objects in a real space, mixed reality (MR) technique is very effective to simulate an overview of a scenery. In interior design, for instance, the coordinates of the arrangements and the colours of the items need to be determined based on various layout plans. We propose a new framework for interactively arranging and rendering(More)
This paper focuses on modeling and rendering of structural color in computer graphics. Structural color is derived from microstruc-ture of an object, which causes various optical phenomena, such as reflection , refraction, diffraction, interference, and so on. In this paper, the authors take 'play of color' of opal as a typical and complex phenomenon of(More)
Recently, we can render real-time CG of liquid which shows various phenomena by global lighting and physical simulation according to the improvement of the computing power. However, the effect sound for real-time CG of liquid should be made corresponding to all the behavior of the liquid beforehand. Therefore, it is difficult for high reproducibility to be(More)
Colors in nature can be classified into two categories: pigment colors and structural colors. Structural colors, which are caused by optical path differences of reflected rays in microstructures, change depending on viewing angle and lighting conditions. In the present paper, we propose a generic approach for rendering structural colors in real-time. The(More)
