Bidirectional path tracing is used to create images of 3D scenes, such that the global illumination is faithful to reality. The naive algorithm is quite inefficient, so many optimized modifications have been developed where one of the most efficient and important extensions is the bidi- rectional approach.

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 …

Different from unidirectional path tracing, bidirectional path tracing generates path from both light sources and eye point and then combines each pair of vertices at two sides, including the traditional path tracing path and light tracing path. In some sense that bidirectional path tracing is a super set of path tracing and light tracing.

Viewed 445 times 1 I'm making a bidirectional path tracer and I have some troubles. To be clear : 1) One point light 2) All objects are diffuse 3) All objects are spheres, even walls (they are very large) 4) NO MIS WEIGHTING The light emission is a 3D vector. The BRDF of a sphere is a 3D vector. Hard coded.

Bidirectional Path Tracing A normal forward path tracer recursively evaluates the rendering equation using Monte Carlo integration. In order to reduce variance, forward path tracers usually evaluate direct and indirect lighting separately at …

1 Bidirectional Path Tracing The Light Transport equation is a self dual, or a self adjoint, process that can swap the incoming and outgoing directions and get the same result. This property is called reciprocity and this symmetric property is a fundamental point of light transport. We have the equation: L r= KGL r+L o
