Research And Application Of Real Time Rendering Component Based On Global Illumination Algorithm

PC machine and the processing ability is improved based on graph, the real-time 3D rendering technology gradually moving into every portions of daily life. Many of them like digital entertainment, architecture design, city layout, and scene simulation have been given continually improving requirements in this technology. Among these requirements, photorealistic, One of the most common, Become an important research topic in the field of computer graphics.At present, the graphics accelerator has the ability to render the scene in real time with millions of triangles. By using the GPU, Local lighting can also be carried out at the same time. Global illumination(GI) has become one of the most important methods. Different local lighting, GI not only consider direct interaction between light and surface but also include radiance distributing after light transferring between different surfaces. Currently, there already has many offline photorealistic renderer shipped with GI rendering engine. Because of the time and memory complexity of the algorithm is expensive, there isn’t any system can do real-time GI on current mainstream PC hardware.The purpose of this thesis is to develop a reusable components of real-time rendering, Provide all kinds of real-time rendering system support. The goal is not to realize completely real-time GI computation, instead to provide a complete solution to use offline computation result in real-time rendering. The final rendering components will be able to use GI and real-time rendering in real-time system results reach the global lighting scenes.
