Abstract: Light transport simulation algorithms are remarkably adept
at recreating a variety of light phenomena which occur in
nature. As such, they have seen widespread adoption across
the industry, which made it paramount to create efficient
and robust algorithms. Probabilistic connections for bidi-
rectional path tracing (PCBPT) represents one such recent
algorithm. Unfortunately, no implementation of PCBPT
was publicly available, which is why we implemented it
into the open-source renderer Mitsuba 1 . We evaluate the
algorithm against standard bidirectional path tracing on a
variety of different scenes. Our comparisons provide in-
sight into the type of scenes for which PCBPT can provide
an improvement and we examine cases where the additional
computational cost presents too much overhead.
