Embodiment Construction

[0060] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0061] Please refer to figure 1 , figure 1 It is a schematic diagram of a hardware structure of a terminal provided in various embodiments of the present invention. The terminal includes components such as a communication module 01 , a memory 02 , and a processor 03 . Those skilled in the art can understand that, figure 1 The terminals shown in may also include more or fewer components than shown, or combine certain components, or have different arrangements of components. Wherein, the processor 03 is connected to the memory 02 and the communication module 01 respectively, the memory 02 stores a computer program, and the computer program is executed by the processor 03 at the same time.

[0062] The communication module 01 can be connected with external devices through the network. The communication module 01 can...

Abstract

The invention discloses a generation method of overflowing holes, a terminal and a storage medium. The method comprises the following steps: acquiring a second central point according to a first central point of a bounding box of a dental arch model, a tooth tip direction and a first preset offset distance; constructing n first rays by taking the second central point as a starting point; taking anintersection point of the first rays and the outer wall surface of the dental arch model as a first intersection point; constructing second rays along a negative direction of a normal of an outer wall surface at the first intersection point by taking the first intersection point as a starting point; acquiring an intersection point, which is nearest to the first intersection point, in the intersection points of the second rays and an inner wall surface of the dental arch model as a second intersection point; constructing a first cylinder penetrating the inner wall surface and outer wall surface of the dental arch model by virtue of a first preset radius; and carrying out Boolean calculation difference set processing on the dental arch model and the first cylinder, so as to generate the overflowing holes. According to the generation method, the problems that the sizes and shapes of overflowing holes generated for a dental arch model in dental three-dimensional design software are fixed,and therefore, partial overflowing holes cannot play a role of overflowing are solved.

Description

technical field [0001] The invention relates to the field of computer-aided design, in particular to a method for generating overflow holes, a terminal and a computer-readable storage medium. Background technique [0002] In order to save printing materials, generally when designing the dental arch model, an open cavity is provided at the bottom of the dental arch model, but when printing the dental arch according to the dental arch model with an open cavity at the bottom, it is first from the The bottom of the dental arch model starts to print, which will cause the bottom of the dental arch model to be in contact with the printing plate, and the originally designed open chamber will be closed to form a closed space, in which printing materials will accumulate and cause printing Material waste, in order to solve this problem, it is necessary to open overflow holes on the dental arch model to discharge the printing materials accumulated during the printing process. However, ...
