詳解

MGCylinder is a Cylinder in 3D space.

Cylinder is expressed by an ellipse and a straight line. Cylinder function f(u,v) = m_ellipse(u) + m_axis(v), where u and v are two parameter of surface representation. Here, m_axis is a straight line whose root point is the origin. MGCylinderクラスは3次元空間における円筒面を表すクラスである。 MGCylinderクラスでは以下のようなパラメータ表現を使用します。 f(u,v) = m_ellipse(u) + m_axis(v);
