Cevap için ümidi kesmişken yanıt ustasından geldi.Teşekkür ederim sad-t.Yeni derslerini sabırsızlıkla bekliyorum.
Bende şöyle bir yanıt buldum.

Interpolation type - a way of interpolation of light exposure of not counted points on light exposure calculated. In the most simple case light exposure of a point is interpolated on the calculated light exposure of the nearest points in the quantity specified in Calc. Pass interpolation samples. Light exposure are summarized with the weight factors depending on distance and a direction of normals. There are only 4 types of interpolation (4 different ways of calculation of weight factors), from them three types are connected with washing out - Weighted average, Least squares fit, Least squares with Voronoi weights and one type without washing out - Delone triangulation. By default VRay uses Least squares fit if the type of interpolation without washing out is necessary - it is applied Delone triangulation, that provides more exact and precise image. However this type of interpolation demands increase in quantity subdivs irradiance map as because of absence of washing out noise in the image does not smooth out.
Sample lookup - a way of a choice of points with the calculated light exposure for interpolation of light exposure of the given point. It is presented three types, the idle time - Nearest, selects successively, everything, that close lays to the given point. The second way - Nearest quad-balanced, divides area near to a point into four parts and tries to take from each part identical quantity of samples, that often leads to use not the best samples for interpolation (too removed). The third way demands an additional step for preliminary processing, but works is not fastest almost than the others - Precalculated overlapping. Demands additional calculation so-called " radiuses of influence " for each calculated light exposure. Such radiuses of influence will be more there where the density irradiance map is less and on the contrary. Then, at rendere light exposure of a point is interpolated only on those points, in lists of " radiuses of influence " which there is this point. The method provides the highest quality.
