Ray tracing is one of the classical global illumination methods to generate a photo-realistic rendering image with various lighting effects such as reflection and refraction. However, there are some restrictions on real-time applications because of its computation load. In order to overcome these limitations, many researches of the ray tracing based on GPU (Graphics Processing Unit) have been presented up to now. In this paper, we implement the ray tracing algorithm by J. Purcell and combine it with two methods in order to improve the rendering performance for interactive applications. First, intersection points of the primary ray are determined efficiently using rasterization on graphics hardware. We then construct the acceleration structure of 3D objects to improve the rendering performance. There are few researches on a detail analysis of improved performance by these considerations in ray tracing rendering. We compare the rendering system with environment mapping based on GPU and implement the wireless remote rendering system. This system is useful for interactive applications such as the realtime composition, augmented reality and virtual reality.

This paper presents a semi-autonomous authoring method which can intuitively create 3D game/ animation contents for unexperienced users. In particular, this method considers their convenience to provide them with easier authoring environments. The 3D game/animation contents created by this method consist of several scene components connected to each other in a logical flow structure. Thus, it is possible to easily understand the overview of 3D content description for its production and manipulate these scene components for efficient management. Four different genres of game/animation contents have been developed by using an authoring tool based on this method. According to results of a survey intended for game developers who created game contents with the authoring tool, this method is shown to save contents development cost/time as well as raise the efficiency and convenience of whole process of contents creation to the expected level.
