Based On Realistic Rendering Engine Architecture And Development

Physically-based render technology is the core and foundation of current computer graphics. It has the key role in many fields as movie effects, CAD, mechanic design, advertisement, digital entertainment and so on. Researching and implementing of it are not having incredible value in technology but also the same for commerce. Unfortunately, a physically-based render application is so complex and difficult to archive since the cross-domain attribute of this technology.CLRE (Coagel Light RayTracing Engine) is a personal project based by the physically-based render technology. It was designed by C++ and have only windows version currently. CLRE chose the Monte Carlo– Raytracing as its core render technology. The combination of Raytracing and radiometry technology made CLRE has a high render quality. CLRE also used a special strategy to tracing the ray that decreases the variant of Monte Carlo technology. At the prophase, CLRE introduced some ideas based on signal processing to benefit the Raytracing fragment's quality and performance. In the metaphase, CLRE used SPD (speculate power distribute) to described the color and light, this successfully led the effort to improve the final result only with a low cost. CLRE use some tone-mapping technology to improve the result's quality on display device (CRT, LCD) in the anaphase.This thesis will introduce the physically-based render technology in a short text, and then introduce the CLRE's framework, creatively technology and rendering pipeline step by step. CLRE is designed as pipeline pattern, so every module on the pipeline will be given a flow chart (by pseudo code) and interface design chart (UML). For the page, the basic algorithm like signal processing and Monte Carlo are not include.
