| Popis: | We present a method to create animations expressing the movement of volumetric smoke by combine still images of Computer Graphics (CG) with a dynamic luminance information. Volume rendering is one of the rendering methods considering absorption and scattering of light by a medium involved in the air such as smoke. It can express smoke more realistic more than normal rendering, and it takes time to create CG video with smoke. In this research, we express smoke motion of the video created using volume rendering by combining a still image by normal rendering with a brightness kinetic information. We experimented to compare perceptual quality of videos created by proposal method and using volume rendering. We used image quality evaluation index and questionnaire for evaluation of perceptual quality. Experiment results show the proposal method can shorten the creation time and create videos keeping perceptual quality of videos using volume rendering. |
