| description | The invention relates to the technical field of medical teaching aids, in particular to a rapid generation method of a blood vessel teaching aid based on automatic advancing of a bounding box, which comprises the following steps of: manually operating to give an initial point and an initial direction vector on original three-dimensional data, and establishing the bounding box by using the initial point and the initial direction vector; performing offset rotation calculation through the initial point and the initial direction vector to obtain the range of the bounding box; based on the range, six surfaces of the bounding box are cut out through a slicing algorithm; solving a blood vessel outlet based on the six surfaces and the blood vessel inlet, and making direction vectors by using the blood vessel inlet and the blood vessel outlet to obtain a known direction vector; re-establishing a bounding box by using a blood vessel outlet and a known direction vector until a point data group is obtained; fitting the p |
