Description

Background Art

[0002] Virtual terrain production is a key link in the virtual game production process. During the virtual terrain production process, virtual object models such as rocks, low vegetation or large plants can be used to decorate the virtual terrain model to make the virtual terrain model more visually rich.

[0003] Usually, since the normals of the surface of the open virtual object model that contacts the virtual terrain model are substantially parallel, decorating the virtual terrain model with the open virtual object model facilitates the connection between the two models and can achieve a better fusion effect.

[0004] However, due to the working characteristics of the 3D engine, after the opening virtual object model is placed in the virtual terrain model, the opening area of ​​the opening virtual object model will be exposed outside the surface of the virtual terrain model, resulting in poor visual effects of the virtual terrain.

[0088] In the related art, a three-dimensional engine can be used to create a three-dimensional virtual scene, wherein in the process of creating a virtual terrain, the three-dimensional engine can determine the normal direction of the surface of the contact portion of the opening virtual object model and the virtual terrain model according to the type of the selected opening virtual object model, and place the opening virtual object model in the virtual terrain model according to the normal direction of the surface of the ground surface in the virtual terrain model and the normal direction of the surface of the contact portion of the opening virtual object model and the virtual terrain model. The three-dimensional engine can include a three-dimensional virtual scene creation engine such as a game engine or an animation engine.

[0089] However, since the three-dimensional engine does not consider the actual shape of the opening virtual object model when placing the opening virtual object model on the virtual terrain model, the opening area of ​​the opening virtual object model placed on the surface of the virtual terrain model will be exposed outside the surface of the virtual terrain model, resulting in a poor visual effect of the produced virtual terrain.

[0090] For example, Figure 1As shown, Figure 1 A partial schematic diagram of a three-dimensional virtual scene provided in a related art is shown, wherein the three-dimensional virtual scene includes a virtual terrain model 101 and an open virtual object model 102 placed on the surface of the virtual terrain model 101, wherein an area 1021 where an opening point of the open virtual object model 102 is located is exposed outside the surface of the virtual terrain model 101, affecting the visual effect of the virtual terrain.

[0093] In which, in an optional implementation, the first terminal 210 can receive a 220 virtual model processing request sent by the second terminal 220, and parse the file to be parsed in the virtual model processing request, wherein the file to be parsed is a three-dimensional virtual scene file including an opening virtual object model; further, the first terminal 210 can load the file to be parsed based on a three-dimensional engine, and according to the virtual model processing method provided in the embodiment of the present disclosure, adjust the position of the opening virtual object model in the three-dimensional virtual scene whose position will affect the visual effect of the virtual terrain.

[0094] In an optional embodiment, the first terminal 210 can create a three-dimensional virtual scene including an opening virtual object model based on a three-dimensional engine, and adjust the position of the opening virtual object model in the three-dimensional virtual scene whose position will affect the visual effect of the virtual terrain according to the virtual model processing method provided in the embodiment of the present disclosure.

[0095] The present disclosure provides a virtual model processing method. Figure 3 A flowchart of a virtual model processing method provided in an embodiment of the present disclosure, the virtual model processing method can be applied to Figure 2 The three-dimensional engine of the first terminal is shown as Figure 3 As shown in , the method includes the following steps S301 to S303:

[0096] Step S301, determining the position information of the opening point of the opening virtual object model in the three-dimensional virtual scene;

[0097] In the disclosed embodiment, the open virtual object model is a virtual object model in a three-dimensional virtual scene, in which there are open edges in the constituent surfaces of the virtual object model, and the open edges are the edges of the constituent surfaces of the open virtual object model that are not co-linear with the constituent surfaces; the open points are the endpoints of the edges of the constituent surfaces of the open virtual object model that are not co-linear with the constituent surfaces, i.e., the endpoints of the open edges. The constituent surfaces may be triangular surfaces or quadrilateral surfaces, etc.

[0098] Step S302, determining the positional relationship between the opening point and the virtual terrain model according to the position information of the virtual terrain model and the position information of the opening point;

[0099] Step S303: if it is determined according to the position relationship that the model position update condition is met, the position of the opening virtual object model is updated.

[0100] To summarize, in the embodiments of the present disclosure, the positional relationship between the opening point of the opening virtual object model and the virtual terrain model can be determined based on the position information of the opening point of the opening virtual object model in the three-dimensional virtual scene and the position information of the virtual terrain model. If it is determined based on the positional relationship that the model position update condition is met, the position of the opening virtual object model is updated, and whether the position of the opening virtual object model in the three-dimensional virtual scene is correct can be determined. The position of the opening virtual object model with an incorrect position can be adjusted to ensure that the opening virtual object model does not affect the visual effect of the three-dimensional virtual scene, thereby improving the aesthetics of the terrain model in the three-dimensional virtual scene.

[0101] Below Figure 3 Each step is described in detail:

[0102] In step S301, the first terminal determines position information of an opening point of an opening virtual object model in a three-dimensional virtual scene.

[0103] In the embodiment of the present disclosure, the position information of the opening point is the position information of the opening point in the three-dimensional coordinate system of the three-dimensional virtual scene, wherein the three-dimensional coordinate system of the three-dimensional virtual scene can be a three-dimensional coordinate system used to construct the three-dimensional virtual scene, for example, a world coordinate system; the position information can be the position coordinates of the opening point in the three-dimensional coordinate system.

[0104] In an optional embodiment, the process of the first terminal determining the position information of the opening point of the open virtual object model in the three-dimensional virtual scene may include: the three-dimensional engine in the first terminal responds to the model virtual model processing instruction, or receives the virtual model processing operation to obtain model processing information, and the model processing information includes the open virtual object model to be processed in the three-dimensional virtual scene; further, the first terminal can determine the position information of the opening point of the open virtual object model in the three-dimensional virtual scene.

[0105] The process of the first terminal determining the position information of the opening point of the open virtual object model in the three-dimensional virtual scene may include: identifying at least one opening edge of the open virtual object model; determining the position information of the endpoints of each opening edge, and obtaining the position information of the opening point of the open virtual object model. The speed of determining the position information of the opening point of the open virtual object model can be improved by identifying the opening edge of the open virtual object model and obtaining the position information of the opening point.

[0106] In an optional embodiment, when the three-dimensional engine does not have the ability to identify open edges, the process of the first terminal identifying at least one open edge of the open virtual object model can be implemented based on the geometry processing (GeometryProcessing) plug-in and the constructor in the three-dimensional engine. The process of the first terminal identifying at least one open edge of the open virtual object model based on the geometry processing (GeometryProcessing) plug-in and the constructor in the three-dimensional engine can include: using the geometry processing GeometryProcessing plug-in to determine the geometric feature data of the open virtual object model, and determining at least one open edge based on the constructor to process the geometric feature data. The geometric feature data may include feature data of the constituent faces of the open virtual object model, for example, the position information of the three vertices of the triangular face constituting the open virtual object model in the three-dimensional coordinate system, and the identification of the triangular face, etc.

[0107] In step S302, the first terminal determines the positional relationship between the opening point and the virtual terrain model according to the position information of the virtual terrain model and the position information of the opening point.

[0108] In the embodiment of the present disclosure, the positional relationship between the opening point and the virtual terrain model is the positional relationship between the opening point and the surface of the virtual terrain model. The positional relationship between the opening point and the virtual terrain model may include the opening point being above the surface of the virtual terrain model, or the opening point being below the surface of the virtual terrain model, or the opening point and the surface of the virtual terrain model overlapping.

[0109] In an optional embodiment, the process of determining the positional relationship between the opening point and the virtual terrain model by the first terminal according to the position information of the virtual terrain model and the position information of the opening point can be implemented based on a ray detection algorithm, wherein the process of determining the positional relationship between the opening point and the virtual terrain model based on the ray detection algorithm according to the position information of the virtual terrain model and the position information of the opening point can include: determining the position of the opening point in the three-dimensional coordinate system according to the position information of the opening point, taking the position of the opening point as the ray origin, emitting a detection ray in the first target direction, and obtaining a first ray detection result; further, the first terminal can determine the positional relationship between the opening point and the virtual terrain model according to the first ray detection result and the position information of the virtual terrain model, wherein the first ray detection result can include the position information of the target object, and the target object is a virtual model in the three-dimensional virtual scene that collides with the detection ray, wherein the first target direction can be a first preset direction of the three-dimensional coordinate system in which the three-dimensional virtual scene is located. wherein the first preset direction can be determined based on the type of the three-dimensional coordinate system in which the three-dimensional virtual scene is located; for example, if the three-dimensional coordinate system in which the three-dimensional virtual scene is located is a world coordinate system, then the first preset direction can be the negative direction of the Z axis.

[0110] Among them, the process of determining the positional relationship between the opening point and the virtual terrain model based on the first ray detection result and the position information of the virtual terrain model may include: comparing the position information of the target object with the position information of the virtual terrain model, if the position information of the target object is the same as the position information of the virtual terrain model, then determining that the target object is a virtual terrain model, and determining that the opening point is above the surface of the virtual terrain model; if the position information of the target object is different from the position information of the virtual terrain model, then determining that the target object is not a virtual terrain model, and further, if it is determined that the position information of the opening point is different from the position information of the virtual terrain model, then determining that the opening point is below the surface of the virtual terrain model; determining that the position information of the opening point is the same as the position information of the virtual terrain model, then determining that the opening point and the surface of the virtual terrain model overlap.

[0111] It should be noted that, in the disclosed embodiment, when all opening points of the opening virtual object model are located below the surface of the virtual terrain model, and the distance between the opening point and the surface of the virtual terrain model is less than a certain distance, it can be determined that the setting position of the opening virtual object model in the three-dimensional virtual scene will not affect the visual effect of the virtual terrain. Therefore, when it is determined that the opening point is located below the surface of the virtual terrain model, it is necessary to determine the distance value between the opening point and the surface of the virtual terrain model.

[0112] In an optional embodiment, the process of the first terminal determining the distance value between the opening point and the surface of the virtual terrain model may include: determining the position of the opening point in the three-dimensional coordinate system based on the position information of the opening point, taking the position of the opening point as the ray origin, emitting a detection ray in the direction of the second target, and obtaining a second ray detection result; wherein the second ray detection result includes the distance value between the opening point and the virtual terrain model, and the distance value between the opening point and the virtual terrain model is used to represent the distance between the opening point and the surface of the virtual terrain model.

[0113] In an optional embodiment, after determining the positional relationship between the opening point of the opening virtual object model and the virtual terrain model, the first terminal can also determine whether the model position update condition is met according to the positional relationship, wherein the process of determining whether the model position update condition is met according to the positional relationship may include: if the positional relationship indicates that the opening point is located below the surface of the virtual terrain model, and the distance value between each opening point of the opening virtual object model and the virtual terrain model is less than or equal to the distance threshold, then it is determined that the model position update condition is not met; otherwise, it is determined that the model position update condition is met. It can be understood that when it is determined that the model position update condition is not met, it means that the position of the opening virtual object model in the three-dimensional virtual scene does not affect the aesthetics of the virtual terrain in the three-dimensional virtual scene.

[0114] In step S303, if the first terminal determines that the model position update condition is met according to the position relationship, the position of the opening virtual object model is updated.

[0115] In the embodiment of the present disclosure, when it is determined based on the position relationship that the model position update condition is met, it can be determined that the current position of the opening virtual object model will affect the visual effect of the terrain model at the location of the opening virtual object model in the three-dimensional virtual scene, and the position of the opening virtual object model needs to be corrected.

[0116] In an optional embodiment, if the position relationship indicates that the opening point is located above the surface of the virtual terrain model, it is determined that the model position update condition is met; the process of the first terminal updating the position of the opening virtual object model may include: moving the opening virtual object model along the first target direction by a first preset distance to obtain the opening virtual object model after the position is updated. Among them, the first preset distance can be obtained from the model processing information, and the first preset distance can be determined based on actual needs, which is not limited in the embodiment of the present disclosure. When it is determined that all the opening points of the opening virtual object model are located above the surface of the virtual terrain model, the opening points of the opening virtual object model can be controlled to move to a position below the surface of the virtual terrain model to prevent the opening points from being exposed outside the surface of the virtual terrain model, which will adversely affect the visual effect of the virtual terrain at the location of the opening virtual object model in the three-dimensional virtual scene.

[0117] In an optional implementation, if the position relationship indicates that at least one opening point is located above the surface of the virtual terrain model, it is determined that the model position update condition is met; Figure 4 As shown, the process of the first terminal updating the position of the opening virtual object model may include steps S401 to S402:

[0118] Step S401 : determining the rotation axis of the opening virtual object model according to the position information of the target opening point and the position information of the center point of the opening virtual object model.

[0119] In the embodiment of the present disclosure, the target opening point is an opening point located above the ground surface of the virtual terrain model in the opening virtual object model, and the position information may be a position coordinate.

[0120] In an optional implementation, based on a rotation axis formula, the rotation axis of the opening virtual object model is determined according to the position information of the target opening point and the position information of the center point of the opening virtual object model. The rotation axis formula is:

[0121]

[0122] Among them, Dir is the rotation axis, A i is the position information of the i-th target opening point among the n target opening points, and B is the position information of the center point of the opening virtual object model; Normalize means normalization, and the rotation axis can be determined according to the target opening point, so as to quickly adjust the position of the opening virtual object model to a suitable position according to the rotation axis to prevent the opening point from being exposed outside the surface of the virtual terrain model.

[0123] Step S402: rotating the opening virtual object model by a preset angle based on the rotation axis, and moving the rotated opening virtual object model by a second preset distance along a first target direction.

[0124] In the embodiment of the present disclosure, the first preset angle and the second preset distance may be obtained from model processing information, and the preset angle and the second preset distance may be determined based on actual needs, which is not limited in the embodiment of the present disclosure.

[0125] In an optional embodiment, the first terminal may rotate the opening virtual object model by a preset angle based on the rotation axis, and move the rotated opening virtual object model by a second preset distance along the first target direction, wherein the process of rotating the opening virtual object model by a preset angle based on the rotation axis may include: rotating the opening virtual object model by a preset angle clockwise based on the rotation axis; or rotating the opening virtual object model by a preset angle counterclockwise based on the rotation axis.

[0126] It should be noted that, in the embodiment of the present disclosure, for an opening virtual object model in which some opening points are located above the surface of the virtual terrain model and some opening points are located below the surface of the virtual terrain model, the position of the opening virtual object model can be adjusted by rotation and movement, and the opening points of the opening virtual object model can be controlled to move to a position above the surface of the virtual terrain model to prevent the opening points from being exposed outside the surface of the virtual terrain model, which would adversely affect the visual effect of the terrain model at the location of the opening virtual object model in the three-dimensional virtual scene.

[0127] In an optional embodiment, if the position relationship indicates that the opening point is located below the surface of the virtual terrain model, then when it is determined that the distance value between at least one opening point and the virtual terrain model is greater than the distance threshold, it is determined that the model position update condition is met; the process of the first terminal updating the position of the opening virtual object model may include: moving the opening virtual object model along the second target direction by a third preset distance, wherein the second target direction is the second preset direction of the three-dimensional coordinate system in which the three-dimensional virtual scene is located, and the distance threshold and the third preset distance may be obtained from the model processing information, and the distance threshold and the third distance threshold may be determined based on actual needs, and the embodiments of the present disclosure do not limit this. Among them, the second preset direction may be determined based on the type of the three-dimensional coordinate system in which the three-dimensional virtual scene is located; for example, if the three-dimensional coordinate system in which the three-dimensional virtual scene is located is the world coordinate system, then the second preset direction may be the positive direction of the Z axis.

[0128] It should be noted that, in the disclosed embodiment, when all the opening points of the opening virtual object model are located below the ground surface of the virtual terrain model, although there is no problem of poor visual effect of the terrain model at the location of the opening virtual object model in the three-dimensional virtual scene due to the opening points being located above the ground surface of the virtual terrain model; however, when the opening points located below the ground surface of the virtual terrain model are far away from the ground surface of the virtual terrain model, there will be a situation where the portion of the opening virtual object model retained above the ground surface of the virtual terrain model is small, and the problem of poor visual effect of the terrain model at the location of the opening virtual object model in the three-dimensional virtual scene will also occur. Therefore, when the position relationship indicates that the opening point is located below the ground surface of the virtual terrain model, and when it is determined that the distance value between at least one opening point and the virtual terrain model is greater than the distance threshold, the opening point of the opening virtual object model is controlled to move to a position close to the ground surface of the virtual terrain model, so as to prevent the portion of the virtual terrain model above the ground surface from being small, which will cause adverse effects on the visual effect of the terrain model at the location of the opening virtual object model in the three-dimensional virtual scene.

[0129] It can be understood that in the embodiment of the present disclosure, if the position relationship indicates that the opening point coincides with the surface of the virtual terrain model, it is determined that the model position update condition is met; the process of the first terminal updating the position of the opening virtual object model may include: if all the opening points of the opening virtual object model coincide with the surface of the virtual terrain model, the opening virtual object model is moved along the first target direction by a fourth preset distance to obtain the opening virtual object model after the position is updated. Among them, the fourth preset distance can be obtained from the model processing information, and the fourth preset distance can be determined based on actual needs, which is not limited in the embodiment of the present disclosure. When it is determined that the opening point of the opening virtual object model coincides with the surface of the virtual terrain model, the opening point of the opening virtual object model can be controlled to move to a position below the surface of the virtual terrain model to prevent the opening point from being exposed outside the surface of the virtual terrain model, which will adversely affect the visual effect of the terrain model at the location of the opening virtual object model in the three-dimensional virtual scene.

[0130] In an optional implementation, after updating the position of the opening virtual object model, the first terminal may also obtain updated position information of the opening point of the opening virtual object model; determine the updated position relationship between the opening point of the opening virtual object model and the virtual terrain model according to the updated position information of the virtual terrain model and the opening point; if it is determined according to the updated position relationship that the model position stop updating condition is satisfied, then stop updating the position of the opening virtual object model; if it is determined according to the updated position relationship that the model position update condition is satisfied, then update the position of the opening virtual object model again until it is determined according to the updated position relationship that the model position stop updating condition is satisfied, and the position adjustment of the opening virtual object model is completed. After updating the position of the opening virtual object model, when it is determined that the position update result of the virtual formation model is not ideal (i.e., the updated position will also affect the visual effect of the terrain model at the position of the opening virtual object model in the three-dimensional virtual scene), the position adjustment of the opening virtual object model may be adjusted again through the virtual model processing process, and the position of the opening virtual object model is adjusted to a suitable position so as not to affect the visual effect of the terrain model at the position of the opening virtual object model in the three-dimensional virtual scene.

[0131] Among them, the process of the first terminal obtaining the updated position information of the opening point of the opening virtual object model can refer to the above-mentioned step S301, and the present embodiment of the disclosure will not elaborate on this; the process of the first terminal determining the updated position relationship between the opening point of the opening virtual object model and the virtual terrain model based on the virtual terrain model and the updated position information of the opening point can refer to the above-mentioned step S302, and the present embodiment of the disclosure will not elaborate on this; the process of the first terminal updating the position of the opening virtual object model again can refer to the above-mentioned step S303, and the present embodiment of the disclosure will not elaborate on this.

[0132] Among them, the process of the first terminal determining whether the model position stop updating condition is met according to the updated position relationship may include: if the updated position relationship indicates that the opening point is located below the surface of the virtual terrain model, and the distance value between each opening point and the virtual terrain model is less than or equal to the distance threshold, then it is determined that the model position stop updating condition is met. When the position of the opening virtual object model is adjusted to not affect the visual effect of the terrain model at the position of the opening virtual object model in the three-dimensional virtual scene, it is determined that the position of the opening virtual object model does not need to be adjusted again, and the virtual model processing flow is terminated in time to prevent waste of data processing resources.

[0133] For example, Figure 5 As shown, Figure 5 A partial schematic diagram of a three-dimensional virtual scene provided in an embodiment of the present disclosure is shown. Figure 5 The three-dimensional virtual scene shown in Figure 1 The three-dimensional virtual scene shown in FIG. 1 is a three-dimensional virtual scene after the position of the opening virtual object model in the three-dimensional virtual scene is adjusted. Figure 5 As shown, the three-dimensional virtual scene includes a virtual terrain model 101 and an opening virtual object model 102 placed on the surface of the virtual terrain model 101, wherein the opening virtual object model 102 has an area outside the surface of the virtual terrain model 101 where there are no opening points, and does not affect the visual effect of the virtual terrain.

[0134] It should be noted that, in the embodiment of the present disclosure, the above virtual model processing process can be implemented in a non-blocking form in the 3D engine, that is, the 3D engine can allow the designer to perform other operations during the execution of the above virtual model processing method, which can further improve the modeling efficiency of the 3D virtual scene.

[0135] For example, Figure 6 As shown, Figure 6 1 shows a flowchart of a virtual model processing method executed by a first terminal. The three-dimensional engine in the first terminal may be a game engine, and the game engine may be a Houdini engine. Figure 6 As shown, the method includes the following steps S601 to S609:

[0136] Step S601, determining the position information of the opening point of the opening virtual object model in the three-dimensional virtual scene;

[0137] Step S602, determining the positional relationship between the opening point and the virtual terrain model according to the position information of the virtual terrain model and the position information of the opening point;

[0138] Step S603, determining whether a model position update condition is met according to the position relationship;

[0139] Step S604: if it is determined based on the position relationship that the model position update condition is not met, the process ends;

[0140] Step S605, if it is determined according to the position relationship that the model position update condition is met, then the position of the opening virtual object model is updated;

[0141] Step S606, obtaining updated position information of the opening point of the opening virtual object model;

[0142] Step S607, determining an updated positional relationship between the opening point of the opening virtual object model and the virtual terrain model according to the updated position information of the virtual terrain model and the opening point;

[0143] Step S608, determining whether a model position stop updating condition is satisfied according to the updated position relationship;

[0144] Step S609, if it is determined according to the updated position relationship that the model position stop updating condition is met, then the position of the opening virtual object model is stopped from being updated, and the process ends;

[0145] Among them, if it is determined according to the updated position relationship that the model position update condition is met, the position of the opening virtual object model is updated again; it is mainly to be noted that, in the embodiment of the present disclosure, the process of updating the position of the opening virtual object model again may include executing the above steps S606 to S609 again, until it is determined according to the updated position relationship that the model position stop updating condition is met, thereby completing the position adjustment of the opening virtual object model.
