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: : 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
