Understanding brute force GI

Brute force is a term used to designate a problem-solving method that simply tries all possible permutations to crack a given problem. Because the Brute force GI mode in V-Ray adopts this all possible permutations approach, it is theoretically capable of producing a perfect GI solution. The Brute force GI engine, which was, for a brief time, called DMC GI, is a calculation method that in many ways is the opposite of the Light cache system.

It is extremely good at picking out scene detail; it is slow when asked to calculate high number of light bounces. It really is not adaptive in anyway at all. It has very few interface controls; in fact, it has only two, and is generally at its best when used as a primary bounce engine. Unlike irradiance mapping, and light cache, the brute force method recomputes the GI values for every single shady point separately and independently from other points.

No interpolation of any sort takes place. There is no averaging across points. In fact, there is no ...
