The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.

The embodiment will be described from the perspective of a virtual component changing apparatus of a virtual object model, which may be specifically integrated in a terminal device, where the terminal device may include a smart phone, a notebook computer, a tablet computer, a personal computer, and other devices.

The method for changing a virtual component of a virtual object model provided in the embodiment of the present application may be executed by a processor of a terminal, as shown in fig. 2, a specific flow of the method for changing a virtual component of a virtual object model mainly includes steps 201 to 205, which are described in detail as follows:

step 201, determining a virtual object model and a virtual component model arranged on the virtual object model.

In this embodiment of the application, the virtual object model may be a three-dimensional virtual object appearing in a game scene, for example, a virtual character model, a virtual prop model, a virtual building model, and the like. The virtual object model may be composed of a plurality of model meshes, and the plurality of model meshes connected to form the virtual object model may be triangular meshes, quadrangular meshes, or the like. Taking a triangular mesh as an example, the vertices of a plurality of triangular meshes are attached and bound to a bone model of the virtual object to form an external contour of the virtual object, and the vertices of each triangular mesh can be controlled by a plurality of bones and thus change along with the change of the bones.

In the embodiment of the present application, in order to make the virtual object more realistic, enrich the external features of different virtual objects, and meet the visual characteristics of the virtual object in different game scenes, at least one virtual component model may be disposed on the virtual object model, for example, the virtual component model may be an attachment of the virtual object, i.e., a wound dressing attached to the face of the virtual character, an eye contour of the virtual character (i.e., a transition treatment between an eyeball and a skin of the virtual character), or a personalized component of the virtual object, i.e., hair, beard, eyelashes, and the like. The model mesh connected to form the virtual part model may be a triangular mesh, a quadrangular mesh, or the like, and the model mesh connected to form the virtual part model may be the same as or different from the model mesh connected to form the virtual object model.

In the embodiment of the present application, in order to form virtual object models in different game scenes, virtual object models before and after transformation may be formed in an art production tool (e.g., 3Dmax, Maya) in advance, and may be represented in a game engine in the form of a skeletal animation or a blendshape.

In the embodiment of the present application, the virtual part model may be set on the virtual object model by a painting manufacturer when the virtual object model is created, or may be set on the virtual object model by a player who acquires the virtual part model for a reason such as completing a mission during a game.

Step 202, obtaining model transformation parameters of the virtual object model.

In this embodiment of the present application, the model transformation parameters may be position parameters of the virtual object model before and after transformation, that is, "obtaining the model transformation parameters of the virtual object model" in step 202 may be: acquiring a first position parameter of a model mesh vertex included in a virtual object model; acquiring a transformed virtual object model according to the first position parameter, wherein the transformed virtual object model comprises a second position parameter of a model mesh vertex; and taking the first position parameter and the second position parameter as model transformation parameters.

In this embodiment, a coordinate system may be created for the virtual object model, the first location parameter may be a coordinate value of a vertex of the model mesh included in the virtual object model in the coordinate system, and the second location parameter may be a coordinate value of a vertex of the model mesh included in the transformed virtual object model in the coordinate system. If the virtual object model is expressed in the game engine in the form of skeleton animation, the model mesh vertex of the virtual object model is connected with the skeleton joint point of the virtual object in a hanging mode, when the virtual object model is changed, the model mesh vertex of the virtual object model moves along with the connected skeleton joint point, namely the first position parameter changes, and finally the second position parameter is formed.

And step 203, controlling the model mesh of the virtual object model to be transformed from the first position to the second position according to the model transformation parameters of the virtual object model.

In the embodiment of the present application, after the model transformation parameters of the virtual object model are obtained, the step 203 of "controlling the model mesh of the virtual object model to be transformed from the first position to the second position according to the model transformation parameters of the virtual object model" may be: determining model mesh vertexes included by the virtual object model according to the first position parameter; connecting model mesh vertexes included in the virtual object model, and determining a first position of the virtual object model; determining model mesh vertexes included in the transformed virtual object model according to the second position parameter; connecting model mesh vertexes included in the transformed virtual object model, and determining a second position of the transformed virtual object model; the model mesh controlling the virtual object model is transformed from a first position to a second position.

And 204, determining position transformation parameters of the model mesh vertexes of the virtual component model according to the second position and the corresponding relation of the relative positions of the model mesh vertexes of the virtual component model and the model mesh of the virtual object model.

In this embodiment of the application, the step 204 of determining the position transformation parameter of the model mesh vertex of the virtual component model according to the second position and the corresponding relationship between the model mesh vertex of the virtual component model and the model mesh of the virtual object model may specifically be: obtaining the position of the model mesh of the transformed virtual object model according to the second position; acquiring a relative position corresponding relation between a model mesh vertex of the virtual component model and a model mesh of the virtual object model; determining the position of a transformed association graph related to the model mesh vertex of the transformed virtual component model according to the position of the model mesh of the transformed virtual object model and the corresponding relation of the relative position; and determining the position transformation parameters of the model mesh vertexes of the transformed virtual component model according to the corresponding relation between the positions and the relative orientations of the transformed associated graphs.

In this embodiment of the application, the second position is a position where the transformed virtual object model is located, so that a position where the model mesh of the transformed virtual object model is located can be obtained according to the second position.

In one embodiment of the present application, in order to obtain a relative orientation correspondence between model mesh vertices of the virtual component model after transformation and model meshes in the virtual object model when the virtual object model changes, a relative orientation correspondence between each model mesh vertex of the virtual component model and a model mesh in the virtual object model may be preset, and the relative orientation correspondence may be recorded in the game engine.

In the embodiment of the present application, the model mesh vertices of the virtual component model may be vertices forming an outer contour of the virtual component model, or may be vertices of all model meshes included in the virtual component model. When the model mesh vertices change, the shape of the virtual part model changes accordingly.

In this embodiment of the present application, the "obtaining a corresponding relationship between model mesh vertices of the virtual component model and relative orientations of the model meshes of the virtual object model" in the above steps may specifically be: acquiring an initial association graph related to a model mesh vertex of the virtual component model in a model mesh of the virtual object model; acquiring a corresponding relation between model mesh vertexes of the virtual component model and the initial associated graph, and projecting the model mesh vertexes of the virtual component model on projection parameters generated in the corresponding initial associated graph; and taking the corresponding relation and the projection parameters as a corresponding relation of relative orientation.

In some embodiments of the present application, in order to make model mesh vertices of the virtual component model vary with the variation of the model mesh of the virtual object model, a corresponding model mesh, i.e. an initial association graph, may be found in the model mesh of the virtual object model for each model mesh vertex of the virtual component model. The method comprises the steps of obtaining the corresponding relation of the model mesh vertexes of a virtual component model and the initial associated graphs, achieving the binding relation of each model mesh vertex of the virtual component model and the corresponding initial associated graph, and after the virtual object model is transformed, transforming the initial associated graphs along with the transformation of the virtual object model to form the transformed associated graphs, so that the transformed associated graphs corresponding to each model mesh vertex of the virtual component model can be obtained in the transformed virtual object model, and determining the positions of each model mesh vertex of the transformed virtual component model in the transformed virtual object model according to the transformed associated graphs having the binding relation with each model mesh vertex of the virtual component model, thereby forming the transformed virtual component model.

In one embodiment of the present application, in order to ensure that each model mesh vertex of the transformed virtual component model is at a unique position in the transformed virtual component model, each model mesh vertex of the virtual component model may be set to uniquely correspond to one initial associated graph in the virtual object model.

In this embodiment of the present application, in order to make the position change of the virtual component model in the virtual object before and after the change smoother and more reasonable, an initial association graph may be determined based on distance relationships between vertices of each model mesh of the virtual component model and the model mesh in the virtual object model, where the obtaining of the initial association graph related to the vertices of the model mesh of the virtual component model in the model mesh of the virtual object model may be:

obtaining a vertex which is closest to a model mesh vertex of the virtual component model from model mesh vertices included in the model mesh of the virtual object model, and taking the vertex as an associated vertex;

obtaining a model mesh taking an associated vertex as a vertex from the model mesh of the virtual object model as a candidate associated graph;

acquiring candidate projection points of model mesh vertexes of the virtual component model projected to each candidate associated graph;

and acquiring a candidate projection point with the closest distance to the associated vertex from the candidate projection points as a target projection point, and acquiring a candidate associated graph where the target projection point is positioned as an initial associated graph.

In one embodiment of the present application, the associated vertex may be a vertex that is closest to a model mesh vertex of the virtual part model on the surface of the virtual object model, i.e. the model mesh vertex of the virtual part model is closest to the associated vertex along the surface of the virtual object model.

In some embodiments of the present application, the associated vertex may also be the vertex that is the closest straight-line distance from a model mesh vertex of the virtual part model, i.e. the straight-line distance between the associated vertex and the model mesh vertex may be the distance formed by penetrating the virtual object model.

In this embodiment, the candidate associated graph may be a model mesh in which the associated vertex is any one of vertices in each direction of the virtual object model.

In an embodiment of the present application, the candidate projection point refers to a point at which each model mesh vertex is projected into the corresponding candidate associated graph, and if the candidate associated graph is small, the corresponding model mesh vertex can be projected into an extended region of the candidate associated graph, so as to form a target projection point in the extended region of the candidate associated graph.

In the embodiment of the present application, the target projection point may be a point closest to the associated vertex along the surface of the virtual object model, and the target projection point may also be a point closest to the associated vertex by a straight line distance.

For example, as shown in a schematic diagram of the initial association graph determining method shown in fig. 3, in the virtual object model before change, a vertex closest to a model mesh vertex V of the virtual component model is J, a model mesh 301, a model mesh 302, a model mesh 303, and a model mesh 304 with J as a vertex are obtained, the model mesh vertex V is projected onto the model mesh 301, the model mesh 302, the model mesh 303, and the model mesh 304, respectively, to obtain a target projection point P closest to the vertex J, and the model mesh 301 where the target projection point P is located is the initial association graph.

In this embodiment of the application, "obtaining a correspondence between a model mesh vertex of the virtual component model and the initial associated graph, and obtaining a projection parameter generated by projecting the model mesh vertex of the virtual component model onto the corresponding initial associated graph" may be:

acquiring the corresponding relation between the first identifier and the second identifier as the corresponding relation between the vertex of the model mesh of the virtual component model and the initial associated graph;

acquiring a model mesh vertex of the virtual component model, and projecting a first projection distance generated in the corresponding initial associated graph;

and taking the relative position relation and the first projection distance as projection parameters.

In the embodiment of the present application, the first identifier is a unique identifier for identifying each model mesh vertex of the virtual part model, for example, the model mesh vertices may be sequentially numbered according to the position distribution of the model mesh vertices on the virtual part model, and the number of each vertex may be the first identifier of each model mesh vertex.

In some embodiments of the present application, the second identifier is a unique identifier for identifying each initial associated graph, for example, each initial associated graph may be numbered in sequence according to a position relationship of the initial associated graph on the virtual object model, and a number corresponding to each initial associated graph may be used as the second identifier of each initial associated graph. It should be noted that, all model meshes on the virtual object model may be numbered, and the number of each initial associated graph is recorded as the second identifier, or only the initial associated graphs may be numbered to obtain the second identifier of each initial associated graph.

In an embodiment of the present application, different identifiers may be added to each model mesh vertex of the virtual component model as a first identifier, different identifiers may be added to each initial associated graph as a second identifier, and the identifier of the model mesh vertex of the virtual component model is the same as the identifier of its corresponding initial associated graph. Wherein, the different marks may be different colors, different shapes, etc. of the marks.

In an embodiment of the present application, the first projection distance may be a distance between a model mesh vertex of the virtual component model and the corresponding target projection point.

In the embodiment of the present application, when the virtual object model changes, the shape of the model mesh on the virtual object model may change, the position of the whole part or all of the model mesh may change, and the like, the relative position relationship between the model meshes does not change, and in the transformed virtual object model, the corresponding relationship between the model mesh vertices of the transformed virtual component model and the relative position of the transformed associated graph does not change, so that the transformed associated graph corresponding to the model mesh vertices of the transformed virtual component model may be obtained based on the preset relative position relationship. In step 203, determining the position of the transformed associated graph related to the model mesh vertex of the transformed virtual component model according to the position of the model mesh of the transformed virtual object model and the corresponding relationship between the relative orientations may be:

acquiring a first identifier of a model mesh vertex of a virtual component model;

and obtaining the model mesh corresponding to the second identifier in the model mesh of the transformed virtual object model as the transformed associated graph, and obtaining the position of the transformed associated graph.

In some embodiments of the present application, the first identifier of each model mesh vertex of the virtual component model does not change with the change of the shape or position of the virtual component model, and the second identifier of the model mesh of the virtual object model does not change with the change of the virtual object model, so that the second identifier corresponding to the first identifier of each model mesh vertex can be obtained according to the correspondence between the first identifier and the second identifier, and the model mesh corresponding to the second identifier in the transformed virtual object model is obtained, that is, the transformed associated graph is obtained, and thus the position where the transformed associated graph is located is obtained.

For example, taking the number of the model mesh vertex of the virtual component model as the first identifier and the number of the model mesh of the virtual object model as the second identifier, based on the correspondence, the number m corresponding to the model mesh vertex with the number n is obtained, and in the transformed virtual object model, the model mesh with the number m is obtained, that is, the transformed associated graph is obtained.

In the embodiment of the application, because each model mesh vertex of the virtual component model is bound with the corresponding initial associated graph, the model mesh vertex can change along with the change of the bound initial associated graph, and therefore, the corresponding relation between the position of the transformed associated graph and the relative position according to which the associated graph is bound is obtained, and the position transformation parameter of the model mesh vertex of the transformed virtual component model can be obtained. The step of determining the position transformation parameters of the model mesh vertices of the transformed virtual component model according to the corresponding relationship between the positions and the relative orientations of the transformed associated graphics may include:

obtaining the relative position relation between the target projection point and the initial associated graph according to the relative position corresponding relation;
