Further this implementation is compared to a parallel implementation of the standard, unidirectional path tracer, in terms of quality and speed. Interactive frame rates have been achieved for parallel bi-directional path tracing, proving the possibility of using such algorithm on GPUs.

3. GPU-OPTIMIZED BPT Instant bidirectional path tracing (IBPT) is unbiased rendering algorithm which generates an image in two independent passes (can be executed in any order): • Path tracing pass (PT). Tracing a path starting at the eye (camera lens). The path is extended until it is terminated with a certain probability by Russian roulette.

The following paper proposes a new parallel implementation of the bi-directional path tracing algorithm for the GPUs. Our approach is compared with existing solutions in terms of both performance and image quality. As the references we use the standard unidirectional GPU path tracer and commercial off-line bidirectional path tracers.
Path tracing - Wikipedia
https://en.wikipedia.org/wiki/Path_tracing
Path tracing is a computer graphics Monte Carlo method of rendering images of three-dimensional scenes such that the global illumination is faithful to reality. Fundamentally, the algorithm is integrating over all the illuminance arriving to a single point on the surface of an object. This illuminance is then reduced by a surface reflectance function to determine how …

Bidirectional path tracing consists of a family of different importance sampling tech-niques for this integral. Each technique samples a path by connecting two independently generated pieces, one starting from the light sources, and the other from the eye. For exam-ple, in Figure 10.1 the light subpath 3 H 82 is constructed by choosing a random point

presented a new technique–bidirectional path tracing [3] which combines the eye path together with the light path, which enormously reduces number of rays with zero con-tribution. The basic idea is that rays are shot at the same time from the viewing point and from a selected light source. After that, all hit points on their paths are inter-
