| dc.description.abstract | It is the aim of this thesis to conduct a thorough analysis related to the effects of parameters on render efficiency or image quality of Path Tracing algorithm known as ReSTIR. In this case, the paper is based on the prior algorithms like ReSTIR, ReSTIR GI, and ReSTIR PT, and provides an integrated viewpoint. The analysis begins by first clearly explaining the ReSTIR algorithm before conducting an extensive examination regarding its multiple parameters influencing it provided speed. As a result, considerable exchanges between/among these parameters and rendering modes are bound to occur. So, the goal is to balance the efficiency gains and quality of the images produced with a ray tracing supported GPU. In this case, therefore, we have employed plots in determining the best values for parameters that dramatically affect the efficiency and image quality of ReSTIR real time rendering. These are all beneficial in mapping which parameters need tuning in order to yield specific renderings. In conclusion, this thesis provides a clear insight about the influence of parameters in ReSTIR (PT) at render efficiency and quality. Such recommendations suggest improvement strategies for different facets of the algorithm, which offer prospects for increasing the runtime rendering speed and the quality of images in ReSTIR-based systems. | |
