The resulting bidirectional path-tracing algorithm (henceforth referred to as BDPT) is a generalization of the standard path-tracing algorithm that can be much more efficient. In contrast to stochastic progressive photon mapping, BDPT is …

MIS weight 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.

ACG 2 04 ' 57 (10.2) 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.

Bidirectional Path Tracing Posted by Zlekdiuson March 12, 2022 · 1 min read Beautiful caustics. Unweighted contribution, MIS weight (power heuristic), and weighted contribution The visualized MIS weights supported my earlier hypothesis that direct caustics in BDPT is mostly contributed by light tracing (t=1 case).

Later in 1993, Lafortune continued with his work and 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.
CALCULATION OF MIS WEIGHTS FOR BIDIRECTIONAL PATH …

There is an in nite set of weights in bidirectional MCRT with own set of weights for each join path length. The weights from di erent sets are de ned in di erent functional spaces (they have di erent number of arguments, i.e. vertices and so on), while all they are \coupled" in the noise functional. There are also problems with ray absorption etc.

bi-directional MCRT there is an infinite set of weights [2], with own set of weights for each join path length. The weights from different sets are defined in different functional spaces (they have different number of arguments, i.e. vertices and so on), while all …
Trace the Ray – Part 8 (Project: Bidirectional Path Tracing)

This issue can be solved by using bidirectional path tracing idea, where in addition to the camera ray path, we also trace a “light ray path” starting from a point on the light towards the objects in the scene, and then connecting these paths to get the final color contribution on the pixel. Below is a screenshot that demonstrates the process:

Getting the MIS weights for bidirectional path tracing is covered in part 2. Onwards! This image compares two methods of rendering a scene where the light source is pointed at a wall, and the rest of the scene is mostly illuminated indirectly.
