Abstract(ENG)

For the 3D game visual effects, the deferred rendering can only consider only the scene image resolution regardless of the scene complexity. Therefore, it is effective in processing realistic visual effects using many geometric buffers as multiple render targets. This paper uses the deferred rendering for the 3D game visual effects such as dynamic lights, specular, shadow, motion blur, and water shading. The 3D game supporting deferred rendering is developed to evaluate various 3D rendering effects with variation of the screen resolution in terms of the rendering speed and PSNR image quality. The performance results show that the rendering speed of the 3D visual effect techniques with 1280x960 resolution is average 56.0% better than that with 640x480 resolution. Also, the average PSNR is getting better as the screen resolution gets higher. The PSNR of the 3D visual effect techniques with 1152x864 resolution is average 30.9% better than that with 640x480 resolution.
