翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク squircle ： ウィキペディア英語版 squircle A squircle is a mathematical shape with properties between those of a square and those of a circle. It is a special case of superellipse. The word "squircle" is a portmanteau of the words "square" and "circle". ==Equation== In a Cartesian coordinate system, the squircle centered on the point (''a'', ''b'') with axes parallel to the coordinate axes is described by the equation: : $\backslash left(\; x\; -\; a\; \backslash right)^4\; +\; \backslash left(\; y\; -\; b\; \backslash right)^4\; =\; r^4$ where ''r'' is the minor radius of the squircle (cf. equation of a circle). The case that is centered on the origin (that is, with ''a'' = ''b'' = 0) is called Lamé's special quartic. 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「squircle」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.
