in step S202, target point information of the target virtual object is acquired, where the target point information is used to represent a target point around which the target virtual object surrounds when rotating.

In the technical solution provided in step S202 of the present invention, the target virtual object is an object model that needs to be processed in the game scene, for example, an object model that needs to be controlled to rotate, which may be a vegetation model. The target point information of the target virtual object may be obtained by calculating the target virtual object to obtain target point information, where the target point information is used to indicate a target point around which the target virtual object rotates, the target point is also a rotation center, may be an origin of a rotation axis, and may be referred to as a pivot point, so that the rotation axis may also be referred to as a pivot axis, and the target point information of the target virtual object is obtained, and may also be pivot point information (model information) of the target virtual object, which may include a pivot point (PivotPoint) and rotation information.

In the technical solution provided by step S204 of the present invention, after the target point information of the target virtual object is obtained, the target point information is mapped to the target map associated with the target virtual object, so as to obtain the map coordinates of the target point.

In this embodiment, the target point information is mapped onto a target map associated with the target virtual object to obtain map coordinates (UV coordinates, texture mapping coordinates, and pivot point coordinates) of the target point, which may be one or more, that is, baking (Bake) the target point information, and the target point information may be mapped onto a third channel (referred to as a UV3 channel or 3U) of the texture coordinates of the target virtual object to obtain map coordinates, which may be referred to as pivot point coordinates or pivot point coordinates, and a corresponding point is a real pivot point of the target virtual object, for recording.

And step S206, determining rotation information of the target virtual object based on the map coordinates, wherein the rotation information is used for controlling the target virtual object to rotate in the game scene.

In the technical solution provided by step S206 of the present invention, after the target point information is mapped to the target map associated with the target virtual object to obtain the map coordinates of the target point, the rotation information of the target virtual object may be determined based on the map coordinates. Optionally, the embodiment may determine the offset of the target virtual object when rotating through wind field information, where the wind field information may be the world wind direction and the size owned by the world attribute, and the rotation information may include at least the direction of the target virtual object rotating around the axis.

That is to say, in the present application, the target point information of the target virtual object is mapped onto the target map associated with the target virtual object to obtain the map coordinates, so as to solve the true rotation center around which the virtual object rotates, calculate the obtained map coordinates, and determine the rotation information of the target virtual object, so as to achieve the purpose of controlling the target virtual object to rotate, which makes the stretching degree of the target virtual object relatively low, solves the technical problem that the stretching feeling of the virtual object during the motion cannot be effectively reduced, and thereby achieves the technical problem that the stretching feeling of the virtual object during the motion is effectively reduced.

The above-described method of this embodiment is further described below.

As an optional implementation manner, in step S202, acquiring target point information of the target virtual object includes: acquiring a vertex of a target virtual object; the vertex is determined as the target point, and the position information of the vertex is determined as the target point information.

In this embodiment, a target number of vertices of the target virtual object may be calculated, the target number being the number of all vertices of the target virtual object. Optionally, since the format of the default map coordinates (UV information) in the 3DSMAX is recorded in the form of a fixed point color, and a position transformation coefficient corresponding to the fixed point color is 255, in this embodiment, the position information of the vertex is first multiplied by 255 to obtain a model fixed point color, which may also be referred to as fixed point color information and may be denoted as invcpos, and then the target number may be regarded as a cycle number (getNumVerts obj), and in each cycle, the product of the position information of each vertex and 255 is mapped onto the target map, so as to map the fixed point color information of all vertices onto the target map, that is, write the fixed point color information of all vertices into the UV3 channel to obtain the map coordinates.

Alternatively, the embodiment may map the position information of the vertices onto the target map based on the target number to obtain the map coordinates in response to the operation instruction acting on the target function control. That is, this embodiment can be used conveniently by the art personnel by adding a target functionality control so that the position information of the vertex is written into the UV3 channel by one key.

Alternatively, in this embodiment, an algorithm for the pivoting of the target virtual object may be implemented in the target engine. Alternatively, a function of rotation around an axis (rota aboutaxis) can input a three-channel vector (x, y, z) related to the rotation, given a rotation axis, a certain point on the rotation axis, and a rotation angle, the function being suitable for producing an animation of better quality than a simple cut using a global position offset (WorldPositionOffset); this embodiment may also receive a normalized (0 to 1) vector by normalizing the rotation axis and angle (normalized rotation angle) function, which may be used to represent the rotation axis, rotation angle of the target virtual object, where a value of 1 is used to represent a full 360 degree rotation; a function of on-axis position (PositionOnAxis) is used to represent the three-channel vector that receives the representation of the pivot point about which the target virtual object will rotate; a Position function is used to receive a three-channel vector representing the Position of the target virtual object. Optionally, the embodiment may automatically create a world position function when creating the function of the rotation around the axis (rotababoutaxi), and take it as an input of the function of the rotation around the axis; in the embodiment, the vertex coordinates of the target virtual object after rotating around the axis can be obtained by converting the angle of the target virtual object in the polar coordinate into the plane coordinate through cosine (cos) and sine (sine).

As an alternative embodiment, in the target engine, the determining the rotation information of the target virtual object based on the map coordinates includes: in a target engine, acquiring offset corresponding to a target virtual object based on a map coordinate; the rotation information is determined based on the offset.

In this embodiment, in the target engine, the offset corresponding to the target virtual object may be obtained based on the map coordinates, the offset of the target virtual object in the global wind field, the offset of the target virtual object in the local wind field, and the outward offset of the target virtual object applied to the periphery with the position of the virtual game character as the center may be obtained based on the map coordinates, the offsets may be world coordinate offsets, all the world coordinate offsets may be added to obtain a final offset of the target virtual object, and the rotation information of the target virtual object may be determined based on the offsets.

As an optional implementation manner, obtaining an offset corresponding to the target virtual object based on the map coordinates includes: determining a first offset of a target wind field of the game scene to a target virtual object based on the map coordinates, and/or determining a second offset of a virtual game character in the game scene to the target virtual object based on the map coordinates; determining rotation information based on the offset, including: and determining rotation information based on the first offset and/or the second offset, wherein the rotation information at least comprises a rotation direction of the virtual object and a rotation axis, and the rotation axis is used for representing the direction of the target wind field.

In this embodiment, the renderer of the target engine includes a global wind farm whose wind farm strength, frequency, and direction can be affected with the public variables in the editor environment. The embodiment may sample a wind field map corresponding to the global wind field, which may be referred to as a wind wave map, for representing a wind field change state in the game scene, for example, determining a wind field frequency change in the world space, and optionally, the wind wave map is a noise map with gradually changing brightness. Optionally, the embodiment may perform spatial transformation on the texture coordinates, for example, perform spatial transformation on the vertex coordinates to transform the position (local) space of the target virtual object into the world space, and then define, in combination with the wind field map, the wind wave fluctuation offset (wind field offset) in the horizontal (U) direction and the vertical (V) direction, so as to achieve the purpose of generating different wind wave fluctuation offsets of the target virtual object in different directions by sampling the wind field map.

Alternatively, the embodiment may calculate the wind wave fluctuation offset by substituting it into the above-mentioned pivoting function to convert it into the offset of the world position vertex.

Optionally, the embodiment may obtain a correct Instance (Instance) matrix space by rewriting the world matrix, and may perform dynamic batch Processing (dynamic batch Processing) on all target virtual objects using the renderer by using the GPU Instance, so that the number of call commands (drawcall) of the underlying graphics rendering interface by a Central Processing Unit (CPU) is reduced, thereby improving the game frame rate.

The World coordinate transformation matrix may be represented by a World Ins matrix when dynamic batching of the plurality of target virtual objects is not enabled, and otherwise, by a variable synthesized World Ins matrix for enabling when batching hardware of the plurality of target virtual objects.

The embodiment introduces a wind field system based on target point information (pivot point information), the target point information is mapped to a target map associated with a target virtual object for recording, the obtained map coordinates are substituted into a renderer of a target engine for calculation, and further rotation information of the target virtual object is determined based on the map coordinates to control the target virtual object.

The above-described method of embodiments of the present invention is further illustrated below in conjunction with the preferred embodiments. Specifically, the target virtual object is taken as a vegetation model, and the target point is taken as a pivot point for illustration.

In the related art, a vegetation model can be manufactured by adopting bone animation, for example, the high-quality vegetation wind field effect is manufactured by adopting the bone animation, but the method has extremely large calculation amount because the bone animation is operated in a bone space and each bone and a father bone have relative space, and is not suitable for processing the vegetation model at a moving end.

Related art also generally processes the vegetation model using a three-dimensional plant tree growth modeling software (SpeedTree) output animation, but the file output by this method is too large and is not suitable for virtual objects without a backbone.

Related art also typically samples and controls the vertex offset in world space through noise, which, while it may exhibit a wave effect, is not fine enough, motion details are too low, and the correlation model stretches more heavily when in motion, depending on the accuracy of the noise mapping.

The related art also typically employs a virtual, unbaked pivot point to effect rotation of the vegetation model about the pivot point. Although the pivot point rotation mode can reduce the stretching condition, the actual pivot point of the vegetation model cannot be effectively eliminated if the actual pivot point is not solved.

MAXScript (3ds Max built-in scripting language) can store pivot point and rotation information in the texture of vegetation models. The texture renderer (Shader) of the NeoX game engine may utilize the texture described above, including pivot point and rotation information, to access and decode the pivot point information of the MaxScript store of the pivot point bag. Every texture that is output by MAXScript can be directly referenced in the texture, but if the appropriate steps are not applied after sampling the texture, the value of the reference will be incorrect.

Creating actions in the manner described above has its advantages. Vegetation models processed using this technique, while using only one more UV channel than static grids, are far less costly to animate than skeletal animations, as they are all computed in real time. In terms of Graphics Processors (GPUs), vertex shaders are generally not as prone to performance issues as pixel shaders, because the number of vertices on a vegetation model is typically significantly less than the number of pixels drawn by the vegetation model.

In the embodiment, for the vegetation model, pivot point information is solved, the pivot point information is mapped into the attribute (UV third channel) of the vegetation model, the coordinate of the pivot point can be substituted into the Shader of the game engine for calculation, and the direction of the vegetation model rotating around the shaft is controlled according to the world wind direction and the size of the world attribute of the NeoX engine. The method of this embodiment is further described below.

Fig. 3 is a schematic view of a vegetation model according to an embodiment of the present invention. As shown in fig. 3, the initial position of the vegetation model needs to be at the origin of coordinates, i.e., its coordinates (X, Y, Z) are (0.0, 0.0, 0.0).

Fig. 4 is a schematic diagram of a vegetation wind farm system based on pivot point information according to an embodiment of the present invention. As shown in fig. 4, the wind farm system of this embodiment is largely divided into a 3d scax model information part and a Shader part in the NeoX engine. Wherein, the 3DSMax model information part comprises: a preprocessing model (a cuboid model is arranged to enable a pivot axis to be consistent with a coordinate axis in the vertical direction and combined with a vegetation model); baking Pivot point information (Bake Pivot information).

Shaders in the NeoX engine of this embodiment may include: global wind field and local wind field. The method comprises the steps that a global wind field can sample a wind map, the strength, the frequency and the direction of the global wind field are influenced by public variables in an editor environment, a periodic function can be made through a sine function in a local wind field, and a swing wind field of a vegetation model in a local coordinate system is made; custom interaction radius and strength, which means that an outward offset to vegetation is applied to the periphery, centered at the virtual game character's position (Get platover).

After the world coordinate offsets of the vegetation in the global wind field, the local wind field and the interaction are obtained, all the world coordinate offsets can be added to obtain a final Offset (WorldPos Offset) of the vegetation, and then the vegetation model is controlled to rotate.

The above technical solution of this embodiment is further described below.

FIG. 5 is a schematic diagram of baking hub point information in 3DSMax according to an embodiment of the invention. As shown in fig. 5, the positions (X, Y, Z) × 255 of the vertices of the vegetation model may be denoted as invcpos, and the model fixed point color may be obtained. And calculating all vertex numbers of the vegetation model, taking the vertex numbers as cycle times (getNumVerts obj), writing invcpos into a UV3 channel of the vegetation model in a cycle body to obtain UV coordinates, wherein for example, U is 0.87, and V is 0.25, and writing the fixed point color information of all the vertices into 3U is realized. Note that in 3DSMAX, the default UV information format is recorded in the form of fixed point colors, and therefore the positions of the vertices of the vegetation model need to be multiplied by 255.

Fig. 6 is a schematic diagram of adding pivot point information of a vegetation model to a UV3 channel according to an embodiment of the invention. As shown in fig. 6, a function button (BakeUV3) is added and the art is facilitated to use the function button, and pivot point information of the vegetation model is added to the UV3 channel.

The pivoting algorithm of this embodiment is described below.

A rotate around axis (rota aboutaxis) function inputs a three-channel vector related to rotation given a rotation axis, a point on the rotation axis, and a rotation angle, the expression being suitable for producing animations with better quality than simple cuts using a global position offset (worldpositiontoffset).

The normalized rotation axis and angle (normalized rotation axis and angle) receives a normalized (0-1) vector that represents the rotation axis, rotation angle, of the object. Where a value of 1 may be used to represent a full 360 degree rotation.

The position on axis (PositionAxis) function is used to represent a three-channel vector that receives the pivot point about which the vegetation model can rotate.

A Position function receives a three-channel vector representing the Position of the vegetation model.

When creating an expression for the function of rotation around the axis (rotababoutaxi), a world position function is automatically created and used as an input to the function of rotation around the axis.

In the embodiment, the vertex coordinates of the vegetation model after pivoting can be obtained by converting the angle in the polar coordinate into the plane coordinate through cos and sine.

According to the embodiment, a wind field map is sampled and used as the wind field frequency change of the vegetation model in the world space, the local swing of the vegetation model can periodically swing through a sine function, and the interactive function of a player on the vegetation model is added.

The embodiment can perform space conversion on the vertex coordinates of the vegetation model, convert the position (local) space of the vegetation model into the world space, define the wind field offset of the vegetation model in the U direction and the V direction, and generate different wind wave fluctuation offsets in different directions according to the sampling of the wind field map.

For the local coordinates of the vegetation model in this embodiment, a sine function may be combined to realize the periodic swing offset of the vegetation model, and the periodic swing offset may be substituted into the above-mentioned function of rotation around the axis (rotababou axis), so as to calculate the offset in the world position.

The embodiment can judge the distance between the virtual game character and the vegetation model, and if the distance is within the set interaction range, the virtual game character is determined to interact with the vegetation model. In the case that the intensity and the interaction range are public exposure variables, a vector can be made towards the vertex position of the vegetation model by taking the virtual game character as the center, and the offset is the product of the vector and the offset intensity.

And finally, adding all the obtained offsets to obtain the final offset of the vegetation model.

Alternatively, the embodiment may derive the correct Instance (Instance) matrix space by rewriting the world matrix. The embodiment can use the GPU Instance to perform dynamic batch processing on all vegetation models using the shader, so that the number of drawcalls is reduced, and the game frame rate is improved.

In this embodiment, the World coordinate transformation matrix of the GPU instance may be represented by a World matrix when dynamic batching is not enabled, otherwise, the World Ins matrix synthesized by variables may be used for enabling at hardware batching. The dynamic batch processing is to calculate a plurality of parameters through the batch operation of the GPU, may be batch processing for parameters of objects with simple models and the same material but in a motion state, and may occur during program operation. Before each dynamic batch processing is performed, a plurality of parameters which can be batch processed are firstly sorted together, then are combined, and then a command is sent to the GPU once, so that the whole operation calculation of the parameters can be completed, and the number of drawcall is reduced, so that the game frame rate is improved, for example, the wind wave chartlet, Texture (Texture), wind field noise index, normalized wind field, local random bending change rate, local random change influence strength, initialized deflection angle, interaction range, interaction smoothness and interaction bending strength are calculated in batch through the GPU, as shown in fig. 7.

Fig. 7 is a schematic diagram of a Shader art user interface in which a plurality of parameters for dynamic batch processing can be set, and optionally, a storm map which is a gray scale map and can be used for describing the intensity change of a wind field can be set according to an embodiment of the invention; texture (Texture) can be set; the value of the wind field noise can be set, and the larger the value is, the smaller the noise transformation of each pivot point is; the wind field noise wave index can be set; the deviation of each pivot point can be controlled; the wind field can be normalized to control the wind direction; a local random bending change rate can be set, which is a swinging speed parameter and can be used for unifying the bending approximation degree of the vegetation model when the vegetation model swings too disorderly; local random variation impact strength can be set; an initial deflection angle can be set for controlling the deflection angle of the model in the initial state; an interaction range can be set, wherein the interaction range is a distance range in which the virtual game role and the vegetation model are subjected to interaction influence; smoothness of interaction, interaction bending strength may be set.

Optionally, the dynamic batch processing of this embodiment may also be a batch operation calculation on multiple parameters of the global wind farm, as shown in fig. 8. Fig. 8 is a schematic diagram of parameters of a global wind farm according to an embodiment of the present invention, where the parameters of the global wind farm may include: the direction, the intensity and the speed can be calculated in batch operation, so that the purpose of calculating the direction, the intensity and the speed in batch operation is realized. The direction is the global wind field direction, the intensity is the global wind field intensity, and the speed is the global wind field speed, so that the setting of the environment of the game scene is realized.

For a game scene which is generated automatically, a large number of vegetation models need to be added with a wind field system to control the shaking direction, and the related art method has the problems of high consumption or low quality. However, the method of the embodiment is applicable to a mobile-end large-batch vegetation wind field system, and DrawCall can be further reduced by using the GPU Instance, so that the performance consumption is reduced and the frame rate is optimized.

The embodiment can calculate the pivot point information of the vegetation; mapping the pivot point information of the vegetation to a UV third channel of the model for recording; the coordinates of the pivot point are substituted into the Shader of the game engine to be calculated, the world wind direction owned by the world attribute of the NeoX engine and the direction of the size control model rotating around the shaft are used, so that the stretching degree of the model is very low, the stormy animation is normal, the technical problem that the stretching sense of the virtual object during motion cannot be effectively reduced is solved, and the technical problem that the stretching sense of the virtual object during motion is effectively reduced is solved.

In this embodiment, in 3DSMAX, the pivot point information is baked in 3U (in UV third channel) of the vegetation model for recording, in game engine NeoX, the wind field direction can be represented by the customized rotation axis with the pivot point as the rotation center, and a noise map with gradually changing brightness can be sampled as the wind field wave change. Thus, a wind field system based on the pivot point information is added into the NeoX engine.

Compared with the wind field system scheme in the related art, the scheme of the embodiment based on the pivot point has the advantages that the stretching degree of the virtual object is very low, the storm animation is normal, and the future expansion can be influenced by constructing multiple layers of wind power by solving the pivot point Index information.
