The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

The invention provides a three-dimensional scene switching control method and device, electronic equipment and a storage medium, which are respectively described below.

As shown in fig. 1, a schematic flowchart of an embodiment of a three-dimensional scene switching control method provided in an embodiment of the present invention is shown, where the method includes:

s101, respectively loading at least two three-dimensional models in a three-dimensional scene, wherein the at least two three-dimensional models are overlapped;

s102, creating at least two cutting models which correspond to the at least two three-dimensional models one to one; the at least two cutting models are overlapped, the normals of the at least two cutting models are opposite, and the at least two cutting models cover the at least two three-dimensional models along the normal directions of the at least two cutting models;

s103, binding the at least two cutting models with the at least two three-dimensional models respectively;

and S104, controlling the at least two cutting models to move along the normal directions of the at least two cutting models at a preset speed and a preset path so as to realize three-dimensional scene switching.

The three-dimensional model in the embodiment of the invention can be any one of a building model, a three-dimensional map model or a game model, and the three-dimensional scene switching control method provided by the embodiment of the invention can be used for carrying out three-dimensional scene switching control on any one of the models.

It should be noted that: the number of the cutting models corresponds to the number of the three-dimensional models one by one, and when the three-dimensional models are bound in the S103, only one cutting model and one three-dimensional model need to be bound.

Compared with the prior art, the three-dimensional scene switching control method provided by the embodiment of the invention has the advantages that the at least two cutting models which are in one-to-one correspondence with the at least two three-dimensional models are created, the at least two cutting models are arranged to be overlapped, and the normals of the at least two cutting models are opposite, so that when the at least two cutting models move along the normal directions of the at least two cutting models at a preset speed and a preset path, the at least two three-dimensional models can be gradually visible or gradually invisible along with the movement of the at least two cutting models because the three-dimensional models are visible in the normal directions of the cutting models corresponding to the three-dimensional models, and the three-dimensional scene switching is realized, namely: the three-dimensional scene display can be gradually switched from one three-dimensional model to other three-dimensional models through the movement of at least two cutting models, the time consumption for switching the three-dimensional scene is short, and the switching is smoother and more vivid.

It should be understood that: the number of loaded three-dimensional models can be adjusted according to actual conditions, and is not limited herein. For convenience of explanation, the following embodiments will be described by taking an example in which two three-dimensional models are loaded in a three-dimensional scene.

In one embodiment of the present invention, as shown in fig. 2, first, a first three-dimensional model a and a second three-dimensional model B are loaded in a three-dimensional scene, wherein the first three-dimensional model a and the second three-dimensional model B may be cylinders, cubes or cones in shape, and in some embodiments of the present invention, the first three-dimensional model a is a cube and the second three-dimensional model B is a triangular pyramid.

In an embodiment of the present invention, as shown in fig. 3, after the first three-dimensional model a and the second three-dimensional model B are loaded, a first cutting model a and a second cutting model B corresponding to the first three-dimensional model a and the second three-dimensional model B are respectively created, wherein the first cutting model a and the second cutting model B are completely overlapped, and normals of the first cutting model a and the second cutting model B are opposite.

Further, since the first three-dimensional model a and the second three-dimensional model B are arranged in an overlapping manner, in order to avoid errors or other problems occurring in the three-dimensional scene after the first three-dimensional model a and the second three-dimensional model B are loaded, after S101, the first three-dimensional model a needs to be set as a visible model, and the second three-dimensional model B needs to be set as an invisible model.

Similarly, when a plurality of three-dimensional models are loaded in a three-dimensional scene, one three-dimensional model needs to be set as a visible model, and other models need to be set as invisible models, so as to avoid errors or other problems of the three-dimensional scene.

Similarly, after S103, in order to realize that the at least two three-dimensional models are respectively visible or invisible with the movement of the at least two cutting models, after S102, the second three-dimensional model B should be set as a visible model, avoiding the problem that the second three-dimensional model B is not visible even with the movement of the second cutting model B.

Further, as shown in fig. 4, when the first and second cutting models a and B intersect the first and second three-dimensional models a and B, the first three-dimensional model a is visible in a normal direction of the first cutting model a; the second three-dimensional model B is visible along the normal direction of the second cutting model B.

Further, to increase the variety of three-dimensional scene cuts, in some embodiments of the invention, the first cut model a or the second cut model b comprises at least one cut plane; and the cutting surface is a plane or a curved surface. The cutting surface can be an irregular plane such as a Bessel curve or a torus.

Specifically, as shown in fig. 3 and 4, the first cutting pattern a or the second cutting pattern b is a plane.

As shown in fig. 5, the first cutting pattern a and the second cutting pattern b are a curved surface.

As shown in fig. 6, the first cutting pattern a and the second cutting pattern b are composed of two planes.

Through the arrangement, the animation diversity of three-dimensional scene switching can be increased, the requirements of different customers are met, and the interestingness and the applicability of three-dimensional scene switching are improved.

Further, the preset speed is constant speed or variable speed.

Through the arrangement, the interestingness and the applicability of three-dimensional scene switching can be further improved.

The specific speed value of the preset speed may be adjusted according to actual requirements to obtain an optimal or most required three-dimensional scene switching effect, which is not specifically limited herein.

Further, in order to avoid increasing the area of the cutting surface when the first three-dimensional model a and the second three-dimensional model B have a large difference in depth, which results in the switching of the three-dimensional scene, in some embodiments of the present invention, the preset path is a straight line or a curved line.

The preset path can be a curve, so that the area of a cutting surface can be reduced, and the three-dimensional scene switching fluency can be further improved.

Furthermore, after the three-dimensional scene is switched, the user needs to perform the scene switching again, and in order to avoid re-creating or calling the cutting model, in some embodiments of the present invention, the preset path may be a reciprocating path, that is: the three-dimensional scene switching can be performed for multiple times, and the speed of performing three-dimensional scene switching again is improved.

Further, as shown in fig. 7, S102 includes:

s701, designing cutting parameters according to requirements, wherein the cutting parameters comprise the initial position of a cutting model, the boundary of the cutting model and the number of cutting surfaces;

s702, at least two cutting models corresponding to the at least two three-dimensional models one by one are created according to the initial positions of the cutting models, the model boundaries and the number of cutting surfaces.
