Image-space Ambient Obscurance in WebGL

Abstract

Image-space approaches to ambient obscurance have become the de-facto standard for realistic ambient lighting in real-time applications. This thesis investigates the potential applicability of such approaches for a WebGL-based implementation. As image-space ambient obscurance has been an active field of research in computer graphics the last few years, a lot of different techniques and enhancements have emerged. This thesis presents a systematic survey of the current state of the art techniques, along with an assessment of their potential for successful implementation using WebGL. Finally, I present a working WebGL-based prototype, yielding good performance and acceptable quality.
