In this embodiment, a terminal is taken as an example for explanation, and this embodiment provides a mesh structure generating method, as shown in fig. 2, the specific flow of the mesh structure generating method may be as follows:

201. at least two reference objects are acquired.

The reference object refers to a pattern selected when generating a mesh structure in a game, and the pattern can be a two-dimensional pattern or a three-dimensional pattern, and can be a regular pattern or an irregular pattern. The dimensions and shape of the reference object may be selected according to practical situations, and the embodiments of the present application are not limited herein.

For example, the reference object may be as shown in fig. 3, and in this case, the reference object may be a two-dimensional graph or a three-dimensional graph.

Alternatively, the terminal may display an object selection interface, and then respond to a selection operation of the object selection interface by a user, taking an object corresponding to the selection operation as a reference object. Then, the terminal may also drag the reference object to a position corresponding to the drag operation in response to the drag operation of the user on the reference object.

Alternatively, the terminal may display an object drawing interface, and then acquire the reference object in response to a drawing operation of the object drawing interface by the user.

Or the terminal can also acquire an image containing the object, then the terminal identifies the image to obtain each object contained in the image, and finally determines a reference object according to each object, for example, each object can be directly used as the reference object, and for example, the reference object can be screened out from each object.

Alternatively, the user may operate on another terminal, and the other terminal acquires the reference object and transmits the reference object to the terminal, and the terminal acquires the reference object.

The form of the reference object acquired by the terminal may be selected according to practical situations, and the embodiment of the present application is not limited herein.

202. And carrying out point scattering processing on each reference object to obtain an initial reference point corresponding to each reference object, and carrying out point adding processing on the initial reference points to obtain a target reference point corresponding to the reference object.

The scattering point processing refers to processing of selecting coordinate points within the coordinate range of the reference object. The terminal may randomly select a coordinate point within the coordinate range of the reference object to obtain an initial reference point, or may select a coordinate point within the coordinate range of the reference object according to the shape and/or dimension of the reference object to obtain an initial reference point.

The number of initial reference points may be selected according to practical situations, and the number of initial reference points of different reference objects may be the same or different.

For example, as shown in fig. 3, when the reference object is a cuboid, a rectangle, and a bird, the initial reference points corresponding to the cuboid, the initial reference points corresponding to the rectangle, and the initial reference points corresponding to the bird may be as shown in fig. 4, and at this time, the number of initial reference points corresponding to the cuboid and the number of initial reference points corresponding to the rectangle are 3, and the number of initial reference points corresponding to the bird is 30.

The point adding process refers to a process of adding coordinate points between the reference objects, and after the point adding process is performed on the initial reference points, additional reference points can be obtained, so that a target reference point is obtained, wherein the target reference point comprises the initial reference points and the additional reference points.

In some embodiments, the process of adding points to the initial reference point to obtain the target reference point corresponding to the reference object may be:

performing interpolation processing or fitting processing according to the initial reference points to obtain interpolated reference points or fitted reference points;

And taking the initial reference point and the interpolated reference point as target reference points corresponding to the reference object, or taking the initial reference point and the fitted reference point as target reference points corresponding to the reference object.

Or, the process of adding points to the initial reference point to obtain the target reference point corresponding to the reference object may also be:

carrying out connection processing on the initial reference points to obtain lines connected between the reference objects;

and according to the line, performing point adding processing on the initial reference point to obtain a target reference point corresponding to the reference object.

For example, the initial reference points are connected in pairs, the obtained lines connected between the reference objects can be shown in fig. 5, then the initial reference points are added according to the lines, and the obtained target reference points corresponding to the reference objects can be shown in fig. 6.

The process of adding points to the initial reference point according to the line to obtain the target reference point corresponding to the reference object may be:

randomly selecting a preset number of coordinate points on the line to obtain target reference points corresponding to the reference object.

Or, according to the line, the process of adding the point to the initial reference point to obtain the target reference point corresponding to the reference object may be:

Performing interpolation processing on the initial reference point according to the line to obtain a reference point after interpolation;

and taking the interpolated reference point and the initial reference point as target reference points corresponding to the reference object.

Or, according to the line, the process of adding points to the initial reference point to obtain the target reference point corresponding to the reference object may also be:

acquiring a preset pattern length;

and adding points to the initial reference point according to the initial reference point, the interpolated reference point and the preset graph length to obtain a target reference point corresponding to the reference object.

The terminal can take coordinate points at two ends of the line as a start coordinate point and a stop coordinate point, then add the coordinate values of the start coordinate point and the stop coordinate point to obtain a total coordinate value, and divide the total coordinate value by 2 to obtain the coordinate value of the middle coordinate point. And finally, determining the current interpolation times, and if the current interpolation times do not reach the preset interpolation times, taking coordinate points at two ends of the line as initial coordinate points and taking the middle coordinate point as a termination coordinate point, and returning to execute the addition processing of the coordinate values of the initial coordinate point and the coordinate values of the termination coordinate point to obtain the total coordinate value. If the current interpolation times reach the preset interpolation times, stopping interpolation, and taking all the intermediate coordinate points obtained in the interpolation process as reference coordinate points after interpolation.

For example, the line L1 is illustrated as an example as shown in fig. 6. The coordinate points at the two ends of the line L1 are respectively A and B, A is used as a starting coordinate point, B is used as a stopping coordinate point, the coordinate value of A and the coordinate value of B are subjected to addition processing to obtain a total coordinate value, and then the total coordinate value is divided by 2 to obtain the coordinate value of the middle coordinate point C.

At this time, the current interpolation frequency of the line L1 is 1 and does not reach the preset interpolation frequency, so that both a and B are used as the start coordinate point, C is used as the end coordinate point, then the coordinate value of a and the coordinate value of C are subjected to addition processing to obtain a total coordinate value, then the total coordinate value is divided by 2 to obtain a coordinate value of the intermediate coordinate point D, the coordinate value of B and the coordinate value of C are subjected to addition processing to obtain a total coordinate value, then the total coordinate value is divided by 2 to obtain a coordinate value of the intermediate coordinate point E, at this time, the current interpolation frequency of the line L1 is 3 and reaches the preset interpolation frequency, and therefore, the interpolation is stopped, and C, D and E are used as reference points after the interpolation.

The preset pattern length refers to a preset length value for dotting processing. The terminal may add a first reference point at a preset pattern length from the initial reference point, add a second reference point at a preset pattern length from the interpolated reference point, and then use the initial reference point, the first reference point, the interpolated reference point, and the second reference point as target reference points.

Or, the terminal may also draw a graph corresponding to the initial reference point and a graph corresponding to the interpolated reference point with the initial reference point and the interpolated reference point as a graph center and with a preset graph length as a graph length, and then perform point scattering processing on the graph to obtain a target reference point corresponding to the reference object.

The dimensions and shapes of the graph corresponding to the initial reference point and the graph corresponding to the interpolated reference point may be selected according to practical situations, for example, the initial reference point and the interpolated reference point may be centers of spheres, the preset graph length may be radii of the spheres, the graph corresponding to the initial reference point and the graph corresponding to the interpolated reference point may be spheres, the spheres may be as shown in fig. 7, for example, the initial reference point and the interpolated reference point may be centers of rectangles, the preset graph length may be side lengths of the rectangles, and the graph corresponding to the initial reference point and the graph corresponding to the interpolated reference point may be rectangles.

In some embodiments, the drawing the graph corresponding to the initial reference point and the graph corresponding to the interpolated reference point with the initial reference point and the interpolated reference point as the graph center and the preset graph length as the graph length includes:

drawing a graph corresponding to the initial reference point by taking the initial reference point as a graph center and taking the graph length after the first adjustment as the graph length;

and drawing a graph corresponding to the interpolated reference point by taking the interpolated reference point as a graph center and taking the second adjusted graph length as a graph length.

The first length adjustment coefficient may be the same as the second length adjustment coefficient, or may be different from the second length adjustment coefficient. The first length adjustment coefficients of different initial reference points may be the same or different, and the second length adjustment coefficients of different interpolated reference points may be the same or different.

In the embodiment of the application, a first length adjustment coefficient corresponding to an initial reference point and a second length adjustment coefficient corresponding to an interpolated reference point are obtained, the first length adjustment coefficient is multiplied by a preset graph length to obtain a first adjusted graph length corresponding to the initial reference point, the second length adjustment coefficient is multiplied by the preset graph length to obtain a second adjusted graph length corresponding to the interpolated reference point, finally, the initial reference point is taken as a graph center, the first adjusted graph length is taken as the graph length, a graph corresponding to the initial reference point is drawn, the interpolated reference point is taken as the graph center, the second adjusted graph length is taken as the graph length, and a graph corresponding to the interpolated reference point is drawn, so that a user can set the graph corresponding to the initial reference point and the size of the graph corresponding to the interpolated reference point according to actual requirements, the subsequently obtained mesh structure can better meet the requirements of the user, and the user experience is improved.

After obtaining the graph corresponding to the initial reference point and the graph corresponding to the interpolated reference point, the terminal can directly perform point scattering processing on the graph, so as to obtain a target reference point corresponding to the reference object. For example, the target reference point may be as shown in fig. 8.

After obtaining the target reference points, the terminal can determine the distance between the target reference points, and then perform the connection processing on the target reference points corresponding to the distances meeting the first preset distance condition to obtain the first candidate grid body corresponding to the reference object.

The first preset distance condition may be selected according to practical situations, for example, a target reference point in a preset range may be used as a target reference point that meets the first preset distance condition, or a target reference point corresponding to a distance equal to the preset distance may be used as a target reference point that meets the first preset distance condition.

For example, when the target reference point may be as shown in fig. 8, the target reference point corresponding to the distance satisfying the first preset distance condition is subjected to the connection processing, and the first candidate mesh body corresponding to the reference object may be as shown in fig. 9.

In some embodiments, in order to make the mesh structure obtained according to the first candidate mesh body more realistic, the process of performing the connection processing on the target reference point corresponding to the distance satisfying the first preset distance condition to obtain the first candidate mesh body corresponding to the reference object may be:
