Problems solved by technology

[0003] However, the existing web model editor does not have the function of automatic explosion and splitting of 3D models, and this function is very practical in lectures, so if users need to use 3D models for lectures, they need to manually split the 3D model , or ask a dedicated modeling engineer to make model animations, which is time-consuming and laborious, and the user experience is poor

Embodiment 2

[0077] The automatic splitting method of described three-dimensional model comprises the following steps:

[0078] S210. Calculate the coordinates of the explosion center point of the three-dimensional model according to a preset algorithm;

[0079] S220. Each of the sub-models moves a first target distance in a direction opposite to the line connecting the explosion center point, and the first target distance is equal to the distance from the sub-model to the explosion center point. a proportional relationship;

[0080] S230. If the bounding box surfaces of the sub-models intersect with each other, each of the sub-models moves again by the first target distance along the direction opposite to the line connecting the respective center point and the explosion center point, until no sub-model exists to enclose The box faces cross each other;

[0081]Specifically, the fact that the bounding box surfaces of the submodels intersect each other means that the bounding box surfaces ...

[0087] The automatic splitting method of described three-dimensional model comprises the following steps:

[0088] S310. Calculate the coordinates of the explosion center point of the three-dimensional model according to a preset algorithm;

[0089] S320. Each of the sub-models moves a first target distance in a direction opposite to the line connecting the explosion center point, where the first target distance is equal to the distance from the sub-model to the explosion center point. a proportional relationship;

[0090] S330. If the bounding box surfaces of the sub-models intersect with each other, each of the sub-models moves the second target distance along the direction opposite to the line connecting the respective center point and the explosion center point until no sub-models have bounding box surfaces intersecting each other. Intersection; the second target distance is in a second proportional relationship with the original distance from the center point of the sub-...

Abstract

The invention discloses an automatic splitting method of a three-dimensional model, computer equipment and a storage medium; the three-dimensional model is composed of at least two sub-models, and theautomatic splitting method of the three-dimensional model comprises the steps that coordinates of an explosion center point of the three-dimensional model are calculated according to a preset algorithm; each sub-model moves by a first target distance along the direction opposite to the connecting line of the sub-model and the explosion center point, wherein the first target distance and the distance from the sub-model to the explosion center point are in a first proportional relation; and the moved positions of all the sub-models are stored. The invention aims to realize automatic explosion splitting of the three-dimensional model, reduce time consumption and manpower consumption and improve user experience.

Description

technical field [0001] The invention relates to the technical field of three-dimensional model splitting, in particular to an automatic splitting method of a three-dimensional model, computer equipment and a storage medium. Background technique [0002] The existing web page model editor uses the web graphics library (English full name is Web Graphics Library, abbreviated as WEBGL) protocol. Allow users to directly edit the 3D model on the web page, and perform operations such as modifying the position, rotation angle, zoom size, texture material, ambient light and other parameters of the 3D model. It brings convenience to the teaching of 3D models. [0003] However, the existing web model editor does not have the function of automatic explosion and splitting of 3D models, and this function is very practical in lectures, so if users need to use 3D models for lectures, they need to manually split the 3D model , or invite a dedicated modeling engineer to make model animation...
