抄録

A visual expression called Energy-Wave, which shows light emission from high-energy fields, is popularly used in creative contents such as animations and computer games. This research proposes a new method for representing energy-Wave in real-time 3D graphics. Conventional energy-wave rendering techniques use the animation texture or the particle animation. However, the animation-texture method restricts the view point, and the boundaries of the energy-wave appear too clearly. The particle-animation method is not suitable for showing a dense energy field and not appropriate for covering a wide region. This paper presents a new method in which the energy distribution is described as a continuous scalar function. The new method is advantageous over the conventional methods since there is no restriction of the view point, resolution, and the covering region. The proposed method also utilizes GPGPU, and the output images are dynamically created from small input and can quickly deform the shape of the energy wave. The previous work of this research was able to deal with point-centered and line-centered energy-distribution functions. The new method can deal with torus-shaped and quadratic curve-centered distribution functions quickly.
