In this paper, we derived an analytical estimator of the local slope in three-point implicit plane-wave destruction. On the basis of this result, we built an accelerated slope estimation algorithm. Examples show that the proposed method can produce a result that is similar to that of the iterative algorithm, at a reduced computation time.

Two or more conflicting slopes can be estimated simultaneously by the iterative algorithm. In this case, the PWD equation is a multi-variable polynomial, and the convergence analysis becomes complicated. The proposed noniterative method is not yet suitable for multi-slope estimation. However, we believe that it can find many applications in situations where one dominant slope is sufficient.
