• Bidirectional search — is a graph search algorithm that runs two simultaneous searches: one forward from the initial state, and one backward from the goal, and stopping when the two meet in the middle. The reason for this approach is that each of the two searches has… …   Wikipedia

• Bidirectional scattering distribution function — The definition of the BSDF (Bidirectional scattering distribution function) is not well standardized. The term was probably introduced in 1991 by Paul Heckbert ref|endnote veach1997 a. Most often it is used to name the general mathematical… …   Wikipedia
