Introduction
A domain-specific language (DSL) is usually defined as a computer language that specifically targets certain special problems. It is not intended to solve non-domain problems. The formal research on DSL has been going on for many years until recently, when programmers try to solve their problems in the most readable and concise way, internal

The image rotation is slightly complicated: The corresponding point after the θ angle is rotated by P0 (x0, y0) is p (x, y ). By using vectors, we can get the following:
X0 = r cos αY0 = r sin α

This section will show you how to generate a ring and various ring-related graphs, including cyclide surface, Horn torus, and tore de Klein.

I have previously written a C ++ program for generating a ring. The code is published on the Generation Algorithm of the ring graph.
