The expressions that a lump of the energy strongly emits light and transforms shape are used as method of attack or special effects in the creation contents. That expressions are called Energy-Wave. This study suggests a new Energy-Wave expression method, in interactive creation contents such as the 3 dimensional video game. The basic concept of this technique is similar to Ray-Casting which is a kind of the Volume Rendering. We omitted a generation of volume data by prescribing 3 dimensional energy distribution data by a line integral. Furthermore, we succeeded of speed up by calculating at line integral function using GPGPU. From these, we drew strength of the light and shape deformation of the Energy-Wave precisely in real-time.
