dc.description.abstract-translatedThis paper introduces a new algorithm for real-time rendering that builds upon bidirectional path tracing, reservoir based spatio-temporal importance resampling, and dynamic diffuse global illumination. The combination of these algorithms produces an image with reduced noise compared to real-time run algorithms like path tracing, while retaining details like caustics. The resulting darkening, which is discussed in greater detail in this paper, is also reduced due to the usage of importance resampling of points on light-emitting surfaces. While the standard al gorithms, such as bidirectional path tracing, cannot be run in real-time with satisfactory quality, a set of novel approaches have emerged to fill this gap. These algorithms are capable of running in real-time, although they do suffer from certain limitations. This paper describes the combination of bidirectional path tracing, DDGI and ReSTIR. This rectifies the drawbacks of missing indirect reflection, darkening and missing caustics of these al gorithms. Ultimately, all the results of these algorithms are compared by verifying real-time rendering time and comparing quality to reference images. The quality is evaluated by using comparions for darkening and the sim ilarity of the real-time rendered result to an offline path-traced result. The results of this paper demonstrate that the algorithm presented improves upon previous algorithms in terms of quality, while still maintaining real-time rendering constraints.en
