Practical implementation of MIS in Bidirectional Path Tracing
https://agraphicsguynotes.com/posts/practical_implementation_of_mis_in_bidirectional_path_tracing/
For a naive bidirectional path tracer, the weight for connecting two sub-paths is simply 1/(s+t+1) where s is the number of vertices in the eye sub-path and t is the number of vertices in the light sub-path, both counting the first vertex sampled on light source or camera sensor.

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

Bidirectional-Path-Tracing. This project extends a rendering framework provided by McGills ECSE 446/546 course to provide Bidirectional Path Tracing and the implementation of perfect mirrors and transmissive materials. This means that there is support for light transport for paths with delta distributions like specular reflection and refraction. The implementation of BDPT …

This paper discusses an experimental implementation of the bidirectional path tracing algorithm. The mathematical derivation of the bidirectional estimator using the Monte Carlo method is shown. Moreover, an explanation on how path tracing and light tracing are subsets of the bidi-rectional approach. Furthermore, a comparison between
