Background

In three-dimensional modeling and virtual scene design, it is often necessary to quickly build up an array of models to create a large-scale layout of objects in a virtual scene. In the prior art, a virtual scene construction tool and three-dimensional modeling software generally provide a function of manually copying and pasting objects, namely, after a user manually selects an object to be copied, a copy model is generated by using the copy and paste function, only one model can be copied and generated once per operation, if a model array is required to be generated, a plurality of models are formed by repeating operation and copying for many times, and then the position and the rotation angle of each copy model are manually adjusted, so that the required model array can be finally generated. The following problems exist in this type of manual replication of model arrays:

(1) The operation process is very tedious, time-consuming and labor-consuming, and especially when a large-scale model array is created, the modeling efficiency is very low, the quick construction of a virtual scene is not facilitated, and errors are easy to cause.

(2) If the model parameters, such as the position and rotation angle of the model, are required to be adjusted, only manual adjustment can be performed on each model respectively, which is very time-consuming, adjustment accuracy is difficult to ensure, and the distance between the models may be inconsistent or the angle is inaccurate, so that the layout is inaccurate, and the quality of the virtual scene is reduced.

(3) For a specific model array, the user also needs to calculate corresponding angle and distance parameters, which further increases the modeling difficulty.

Detailed Description

The invention is further described below in connection with the drawings and the specific preferred embodiments, but the scope of protection of the invention is not limited thereby.

Example 1:

as shown in fig. 1, the method for generating model array replication in three-dimensional virtual scene modeling according to the embodiment includes the following steps:

and S01, after a model array copying function is started, obtaining a model array arrangement mode selected by a user and initial model parameter setting.

In an alternative embodiment, in the three-dimensional virtual scene construction environment, by setting a model array replication function button, when the user clicks the button, that is, the model array replication function is started, the model array arrangement mode selected by the user starts to be detected. The model array arrangement mode can be set into a linear array mode, an annular array mode and the like according to actual requirements, wherein the linear array mode is that all units in the array are arranged in a linear mode according to specified intervals, and the annular array mode is that all units in the array are arranged in an annular mode according to specified intervals. The model array arrangement mode can also be provided for user selection by setting corresponding buttons.

It can be understood that, besides the above modes, other modes can be adopted according to actual demands, for example, the mode of starting the model array replication function is triggered by a specific clicking mode, a list mode is adopted to allow a user to select the model array replication mode, besides the linear arrangement mode and the annular arrangement mode, the user can select other different arrangement modes according to specific demands, and the diversity of arrangement is increased.

In an alternative embodiment, the model parameters are related parameters such as model angle, inter-model distance, etc. The model parameter settings of different model array arrangement modes are different. For example, the model parameters in the linear array mode include the angle of the models, the distance between the models, the number of models, and the like. Model parameters for the annular array mode include the angle of the model, the radius of the annulus, the number of models, etc. The model parameters can be specifically configured according to actual requirements.

And S02, detecting the operation of selecting the target model object to be copied by the user, recording the coordinate position of the target model object and calculating the corresponding bounding box size when the target model object selected by the user is detected.

In an alternative embodiment, after the model array copying function is started, the user's selection operation on the target model object is started, if the user selects a certain target model object, the coordinate position of the target model object is recorded and saved, and meanwhile, the length, width and height of a rectangular bounding box surrounding the target model object are calculated to obtain the size data of the bounding box, and the bounding box is displayed at the target model object to identify that the bounding box has been selected.

S03, creating a plurality of bounding boxes with the same size according to the bounding box size of the target model object to form a bounding box array.

In an alternative embodiment, a plurality of bounding boxes with the same size are synchronously copied according to the size of the bounding box of the target model object, and each copied bounding box is displayed in the interface, wherein the copy number of the models can be set in advance through model parameters.

And S04, when a copy request operation of a user is received, starting to detect the position of a user operation point, mapping the position of the user operation point to a plane where the position height of a target model object in the virtual scene is located, and updating the positions of the bounding boxes in the bounding box array according to the starting point position selected by the user, the position of the user operation point, the model array arrangement mode selected by the user and the initial model parameters.

In an alternative embodiment, the user sends the copy request operation through the mouse click operation or other specified operation, and when the mouse click operation or other specified operation of the user is detected, the detection of the position of the user operation point is further started, for example, the position of the user mouse is detected, the position of the user mouse is taken as a starting point when the mouse clicks operation, the real-time movement position of the mouse is taken as an end point position, and the position of the bounding box array is updated in real time according to the initial model parameter configuration according to the user selected starting point position, end point position and the user selected model array configuration mode, so that the effect that the bounding box array changes correspondingly along with the change of the user operation point is presented. For example, if the model is a linear array model, determining the position of the bounding box array according to the starting point position and the real-time position of the operating point selected by the user, so that the bounding box array is in linear arrangement, determining the angle, the distance, the number and the like of the model according to the initial model parameter configuration, and updating the position of the bounding box array after the operating point of the user moves.

According to the embodiment, before the confirmation operation is received, the positions of the bounding boxes in the bounding box array are updated in real time according to the positions of the user operation points, so that the functions of instant preview and real-time feedback can be achieved, the model array copying state can be displayed to the user in real time when the positions of the different operation points are displayed, the user can better understand the layout of the model array, and errors and unsatisfied conditions are reduced.

It can be understood that the detection of the copy request operation and the detection of the user operation point can be realized in other modes besides the above mode according to the actual demand configuration. For example, a double click or other specific clicking manner may be used to click on a location of the target model object as a copy request operation.

And S05, stopping updating the positions of the bounding box arrays when receiving confirmation request operation of a user, and copying data of the target model object to the positions of all bounding boxes in the bounding box arrays respectively to generate a required model array.

In an alternative embodiment, if a confirmation request operation of a user, such as a mouse click operation of the user, is detected during the process of updating the position of the bounding box array in real time, the position of the bounding box array is stopped from being updated by taking the confirmation operation of the user as a final end position, that is, the position of the bounding box array is determined, and after the data of the target model object are copied to the positions of the bounding boxes, the model array consisting of a plurality of models can be directly generated in batches.

According to the method, a user can quickly establish a batch of model arrays, complicated manual operation is reduced, the method can be suitable for complex scene modeling tasks, quick replication of model arrays with various sizes is achieved, the whole operation process is simple, model parameters can be automatically calculated in the process of establishing the model arrays, efficient and accurate layout of virtual scene models can be achieved, efficiency and accuracy of virtual scene modeling are greatly improved, operation difficulty of the user can be reduced, and user experience is improved.

In an alternative embodiment, the method further comprises a model parameter adjustment step, the model parameter adjustment step comprising:

detecting modification data of a user on model parameters;

and modifying the data according to the detected model parameters to adjust the corresponding parameter states of the model array.

In the conventional model replication method, once the model array is created, if the layout needs to be changed or the number of replication objects needs to be increased/decreased, the user needs to perform manual operations again, which makes it difficult to further adjust and maintain the model. According to the application, the model array parameters are generated in an editable mode according to the initial model parameters, and then the angles, the intervals, the quantity and other states of the model array are automatically adjusted according to the modification data of the user when the adjustment is needed, so that the user can flexibly adjust the parameters of the model array according to the requirements, the modeling requirements of different scenes are met, the flexibility of scene modeling is improved, the layout accuracy of the model array can be ensured, the errors and inaccuracy of manual adjustment of the user are reduced, and the modeling accuracy is improved. The user can immediately see the change of the model array when adjusting the parameters, does not need to wait for a complex calculation process, can realize a real-time feedback function, and further improves the modeling efficiency of the user.

In an alternative embodiment, the above scheme is implemented by adopting an intelligent interaction technology, so that the user can adjust the layout in an intuitive manner, and the interactivity between the user and the virtual scene can be increased.

In a specific application embodiment, the first click of the mouse is used as a start copy request, the second click of the mouse is used as a confirm copy request, namely, the first click of the mouse is detected as a starting position, the start of the real-time update calculation of the position of the bounding box array is started, the second click of the mouse is used as a determined end position, and the update is stopped. As shown in fig. 2, firstly, whether a model is selected is detected, and if the model is selected, a surrounding square array with the size of the model is generated; detecting whether a mouse clicks, if so, calculating an angle and a distance and surrounding square array positions according to the position of the mouse, and updating and displaying; detecting whether the mouse clicks again, if so, determining the end point position, and stopping updating the model array position; detecting whether the parameters in the model parameter setting panel are modified, if so, recalculating the model array position, updating the array effect, and if the pressing of the confirm button is detected, generating a final array.

Example 2:

The present embodiment is basically the same as embodiment 1, except that the present embodiment is a case where the model array arrangement mode selected by the user is a linear array mode. After a model array copying function is started, detecting that a user selects a linear array mode, wherein model parameters in the linear array mode comprise angles, distances, quantity and the like, when the positions of all bounding boxes in the bounding box array are updated in real time, the positions of all the bounding boxes in the bounding box array are updated according to niPos = startPos +offset, wherein i=1-n are sequence numbers of the bounding boxes, n is the quantity of the bounding boxes in the bounding box array, startPos is a starting point position coordinate, offset is an offset between an end point position coordinate and the starting point position coordinate, the angle of the bounding box array is obtained according to an included angle between a first vector and a second vector, the first vector is a vector in which the orientation of a target model object is located, and the second vector is a vector between the starting point position and the end point position.

In this embodiment, the specific step of adjusting the corresponding parameter states of the model array according to the detected model parameter configuration data includes:

If the angle parameter modification data are detected, the world Z-axis direction vector is rotated by a designated angle according to the modification data to obtain a new v1 unit vector, the end position and the offset are recalculated according to the new v1 unit vector, and then the position of the model array is calculated and updated according to the recalculated offset.

Specifically, when it is detected that the angle parameter is modified, the world Z-axis direction vector is rotated by an angle to obtain a v1 unit vector, the end position endPos is recalculated according to endPos = startPos +distance v1, the offset value offset is recalculated according to the formula offset= endPos-startPos, the new array model position is calculated according to the formula niPos = startPos +offset i (i=1 to n) according to the offset value offset, and the position of the model array is updated.

If the distance parameter modification data are detected, a new end point position is calculated according to the modification data and a direction vector v2 between the initial position and the end point position before modification, an offset is recalculated according to the new end point position, and then a new array model position is calculated according to the recalculated offset and updated.

Specifically, when a modification of the distance parameter is detected, the end position is calculated according to the formula endPos = startPos +distance v2.normalized according to the original direction vector v2= endPos-startPos from the start position to the end position, normalize represents vector normalization for maintaining the direction of the vector unchanged, the offset is recalculated according to the formula offset= endPos-startPos according to the new endPos, the new array model position is calculated according to the formula niPos = startPos +offset i (i=1 to n) according to the offset, and the position of the model array is updated.

If the distance parameter modification data is detected, regenerating a corresponding number of array models, calculating the position of a new array model according to the current offset and updating.

Specifically, when the modification of the quantity parameter is detected, a corresponding quantity of array models are regenerated, new array model positions are calculated according to the offset according to the formula niPos = startPos +offset, and the positions of the array models are updated.

The following takes a state machine to implement the replication process of the model array in a specific application embodiment as an example, and includes three states of switching, specifically:

State one: detecting target model objects

After detecting that a user starts a linear array mode, switching to a first state, after detecting that the user selects a model object, recording the coordinate position of the model as p1 (x 1, y1, z 1), calculating the length, width and height size s1 of a bounding box of the model, creating n square bounding boxes according to the number n of arrays initially configured, wherein the position and the length, width and height size are the same as those of the selected model object, and switching to a second state.

State two: real-time update adjustment array

Starting to detect a user clicking mouse event during the state, when the user clicking mouse is detected, mapping the mouse position onto a plane with the height of the model position height y1 in the virtual scene, recording the starting point position as mapping coordinates startPos (x 2, y1, z 2), mapping the user mouse position (operation point position) onto the plane every frame to obtain a real-time end point position endPos (x 3, y1, z 3), subtracting the starting point position from the end point position coordinate to obtain an offset (x 3-x2,0, z3-z 2), and obtaining coordinate positions niPos = startPos +offset i (i=1-n) of n bounding boxes in the model array, and updating the bounding box array position in real time.

Wherein, the distance in the model parameter is the distance between the two points of the starting point and the end point, and the calculation mode is distance= v ((x 3-x 2) 2+ (z 3-z 2) 2); the angle is the angle between the model object towards the a vector and the vector b from the start point to the end point, and is calculated in such a way that angle=vector 3.Angle (a, b) ×mathf. Sign (vector 3.Dot (n, vector3.Cross (a, b))), wherein vector3.Angle (a, b) represents the angle between the a vector and the b vector, mathf. Sign (n) represents the sign of n, 1 if n is a positive number, -1 if n is a negative number, -0 if n is a 0, vector3.Cross (a, b) represents the cross product of the a, b vectors, and vector3.Dot (a, b) represents the dot product of the a, b vectors. Therefore, the real-time distance and angle data can be calculated and displayed on the parameter panel, so that the model array can be observed and generated in real time to be in a parameter state.

When the second mouse click operation of the user is detected, the final end position is determined, the position of the entire model array is not updated any more, as shown in fig. 3 (b), and then the state is switched to the state three.

State three: detecting parameter adjustment array effects

Quantity: when a number parameter modification is detected, a corresponding number of array models are regenerated, new array model positions niPos = startPos +offset i (i is 1-n) are calculated according to the offset and the positions of the array models are updated.

After detecting that the user presses the confirm button, the linear array model of the target model is finally generated according to the array pre-generation position, and as shown in fig. 3 (c), the state is switched back to the state to wait for the next copy.

Example 3:

The model parameters in the annular array mode comprise parameters such as angles, radiuses and quantity, after a model array copying function is started, when the user selects the annular array mode, after the copying request operation of the user is received, an identifier is generated at the position (the position of the user operation point is mapped to the position carried on the plane where the position height of the target model object in the virtual scene is located) after the position mapping of the user operation point is received, and the positions of the bounding boxes in the bounding box array are updated according to the positions of the generated identifiers serving as circle centers and the distances from the circle centers to the target model object serving as radiuses.

In this embodiment, when updating the position of each bounding box in the bounding box array, specifically, an angle between the world Z-axis direction dz and a vector v1 is obtained according to the formula angle=vector3.angle (dz, v 1), where the vector v1 is a vector obtained by subtracting the center coordinates from the mapping coordinates obtained by mapping the user operation points, the position of each bounding box in the bounding box array is niPos =quaternion.angle (i×angle, vector3.up) ×p 1-startPos) + startPos, i=1 to n is the number of bounding boxes in the bounding box array, n is the starting point position coordinates, startPos is the starting point position coordinates, quaternion.angle is (a, b) is the rotation reference axis direction, vector3.up is the Y-axis quantity with coordinates of (0, 1, 0), and p1 is the position of a state in which p1 is the model (x 1, Z1).

In this embodiment, the step of adjusting the corresponding parameter states of the model array according to the detected model parameter configuration data includes:

if the angle parameter modification data are detected, the coordinate positions of the models in the array are recalculated and updated according to the modified angle data.

Specifically, when the modification of the angle parameter is detected, the coordinate positions of n models in the array are calculated according to the formula niPos =quaternion.

If radius parameter modification data are detected, recalculating the circle center position according to the modification data and a direction vector v2 between the target model object and the circle center before modification, calculating the positions of the models in the model array according to the recalculated circle center position, and updating.

Specifically, when the radius parameter is detected to be modified, calculating the center position according to the formula startPos =p1+r×v2.normalized according to the original direction vector v2= startPos-p1 between the starting point position and the center position, and recalculating the position of the model array according to the new startPos according to the formula niPos =quaternion.
