Translation guide
A torus is a doughnut-shaped geometric surface. In Japanese, it is usually referred to by the loanword トーラス or the native term 円環面. The concept appears mainly in mathematics, 3D modeling, and some traditional objects.
The mathematical surface or solid shaped like a doughnut, generated by revolving a circle around an axis.
The standard loanword from English, widely used in mathematics, computer graphics, and technical contexts.
Objects that resemble a torus, such as certain traditional rings or ceremonial items.
In most modern contexts, especially in computer graphics and informal math discussions, トーラス is preferred. 円環面 is more formal and may appear in academic papers or textbooks.
トポロジーでは、トーラスはよく使われる例です。
In topology, the torus is a commonly used example.
This 3D model is made of a torus.
A native Japanese term meaning 'circular ring surface'. Used in mathematical contexts, but less common than トーラス.
円環面の体積を計算してください。
Please calculate the volume of the torus.
Literally 'doughnut shape'. Used informally to describe the shape, but not a formal mathematical term.
この部品はドーナツ形をしています。
This part has a doughnut shape.
This metal ring is made of iron.
A ring or circle, often used for large rings like those on a ship or in traditional settings. Not specifically a torus, but can describe a ring shape.
