翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Gradient noise ： ウィキペディア英語版 Gradient noise Gradient noise is a type of noise commonly used as a procedural texture primitive in computer graphics. It is conceptually different, and often confused with value noise. This method consists of a creation of a lattice of random (or typically pseudorandom) gradients, which are then interpolated to obtain values in between the lattices. An artifact of some implementations of this noise is that the returned value at the lattice points is 0. Unlike the value noise, gradient noise has more energy in the high frequencies. The first known implementation of a gradient noise function was Perlin noise, credited to Ken Perlin, who published the description of it in 1985. 〔David Ebert, Kent Musgrave, Darwyn Peachey, Ken Perlin, and Worley. ''Texturing and Modeling: A Procedural Approach.'' Academic Press, October 1994. ISBN 0-12-228760-6〕 Later developments were Simplex noise and OpenSimplex noise. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gradient noise」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
