MINRES is formally equivalent to applying CR to Ax=b when A is positive definite, but is typically more stable and also applies to the case where A is indefinite. WitrynaImprovement with Hermitian Smoothing ----- Smoothing yields an improved result, but there are obvious grid features in there. Some of it is Mach bands, a known perceptual artifact of linear interpolation of color. A standard trick is to use a Hermite cubic to round off the interpolation: ~~~~~ C++ class perlin ( public: ...
