Download or read book GPU based Techniques for Global Illumination Effects written by László Szirmay-Kalos and published by Morgan & Claypool Publishers. This book was released on 2008 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents techniques to render photo-realistic images by programming the Graphics Processing Unit (GPU). We discuss effects such as mirror reflections, refractions, caustics, diffuse or glossy indirect illumination, radiosity, single or multiple scattering in participating media, tone reproduction, glow, and depth of field. The book targets game developers, graphics programmers, and also students with some basic understanding of computer graphics algorithms, rendering APIs like Direct3D or OpenGL, and shader programming. In order to make the book self-contained, the most important concepts of local illumination and global illumination rendering, graphics hardware, and Direct3D/HLSL programming are reviewed in the first chapters. After these introductory chapters we warm up with simple methods including shadow and environment mapping, then we move on toward advanced concepts aiming at global illumination rendering. Since it would have been impossible to give a rigorous review of all approaches proposed in this field, we go into the details of just a few methods solving each particular global illumination effect. However, a short discussion of the state of the art and links to the bibliography are also provided to refer the interested reader to techniques that are not detailed in this book. The implementation of the selected methods is also presented in HLSL, and we discuss their observed performance, merits, and disadvantages. In the last chapter, we also review how these techniques can be integrated in an advanced game engine and present case studies of their exploitation in games. Having gone through this book, the reader will have an overview of the state of the art, will be able to apply and improve these techniques, and most importantly, will be capable of developing brand new GPU algorithms.

Download or read book A GPGPU accelerated Texture based Radiosity Technique with Support for Dynamic Environments written by Sungkono Surya Tjahyono and published by . This book was released on 2012 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: Real-time global illumination is the holy grail of the computer graphics field. Even with the current generation of graphics hardware, real-time global illumination is still a very challenging concept. This thesis investigates the applicability of the Graphics Processing Unit in calculating the radiosity of 3D scenes using computing frameworks. Support for dynamic environments in a radiosity technique is also investigated. A radiosity framework has been developed which combines techniques such as texture-based subdivision, hemicube rendering, and multiplier map in addition to the CUDA and OpenCL frameworks to calculate the radiosity of 3D scenes. The framework is used to investigate the effects of rendering parameters such as texture array dimensions and hemicube resolutions on the overall performance of the Graphics Processing Unit. The radiosity framework shows that the Graphics Processing Unit can perform calculations at a much faster rate than the Central Processing Unit. Increasing texture array dimensions increases the performance logarithmically while increasing the hemicube resolution reduces the performance linearly. One of the main contributions of this research is the implementation of a radiosity technique that supports dynamic environments in the forms of geometry and surface property modifications. The main advancement over existing techniques is that the support for dynamic environments is built-in as part of the radiosity calculations. Furthermore, the radiosity can be calculated while the modification is processed and no prior knowledge of the modifications is needed. The dataset and framework presented in this thesis can be used for further development and a foundation for integrating global illumination into interactive virtual environments such as computer games.

Download or read book Real time Realistic Rendering of Nature Scenes with Dynamic Lighting written by Kévin Boulanger and published by . This book was released on 2008 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rendering of natural scenes has interested the scientific community for a long time due to its numerous applications. The targeted goal is to create images that are similar to what a viewer can see in real life with his/her eyes. The main obstacle is complexity: nature scenes from real life contain a huge number of small details that are hard to model, take a lot of time to render and require a huge amount of memory unavailable in current computers. This complexity mainly comes from geometry and lighting. The goal of our research is to overcome this complexity and to achieve real-time rendering of nature scenes while providing visually convincing dynamic global illumination. Our work focuses on grass and trees as they are commonly visible in everyday life. We handle geometry and lighting complexities for grass to render millions of grass blades interactively with dynamic lighting. As for lighting complexity, we address real-time rendering of trees by proposing a lighting model that handles indirect lighting. Our work makes extensive use of the current generation of Graphics Processing Units (GPUs) to meet the real-time requirement and to leave the CPU free to carry out other tasks.
