Detailed Description

In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only partial embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

According to an aspect of an embodiment of the present application, there is provided a method of rendering an object. Alternatively, in the present embodiment, the rendering method of the object may be applied to a hardware environment formed by the terminal 102 and the server 104 as shown in fig. 1. As shown in fig. 1, the server 104 is connected to the terminal 102 through a network, which may be used to provide services (such as game services, application services, etc.) for the terminal or a client (e.g., game client) installed on the terminal, may be provided with a database on the server or independent from the server, may be used to provide data storage services for the server 104, and may be used to handle cloud services, and the network includes but is not limited to: the terminal 102 is not limited to a PC (Personal Computer), a mobile phone, a tablet Computer, and the like. The rendering method of the object in the embodiment of the present application may be executed by the server 104, may be executed by the terminal 102, or may be executed by both the server 104 and the terminal 102. The terminal 102 may perform the rendering method of the object according to the embodiment of the present application, or may perform the rendering method by a client (e.g., a client of a target game) installed thereon.

Taking the method for rendering an object in this embodiment executed by the server 104 as an example, fig. 2 is a schematic flowchart of an optional method for rendering an object according to an embodiment of the present application, and as shown in fig. 2, the flowchart of the method may include the following steps:

in step S202, a first height map corresponding to the target spraying object is acquired, where the first height map is used to represent height values of the spraying color at various positions of the target spraying object before the first spraying color is sprayed.

The rendering method of the object in this embodiment may be applied to a scene in which paint is sprayed on the spraying object in an event scene, where the event scene may be a game scene, or another scene in which paint needs to be sprayed on the spraying object in the scene.

The game scene may be a game scene (e.g., a three-dimensional game scene) of a target game. The target game can be a single-player game or a multi-player game; it can be a match-up game (for example, a multiplayer online match-up game with paint and graffiti as a theme) or a non-match-up game (for example, a commercial game); can be used for end-play or hand-play. For example, the target game may be an MMO (Massive Multiplayer Online) game, an AR (Augmented Reality) game, a VR (Virtual Reality) game, or another type of game, and the game type is not limited in this embodiment.

Taking a multiplayer competitive game as an example, the target game may be NVN (e.g., 1V1, 4V4, 5V5, etc.) multiplayer battle game, and the multiplayer battle may have at least two battle parties, and two battle parties are exemplified in this embodiment. The target game may have one or more modes, different game modes may correspond to one or more play difficulties (e.g., simple, standard, difficult, etc.), and the number of players permitted for each mode may be the same or different.

The target game may have one or more game scenarios, each game scenario may correspond to one or more game modes and may also correspond to one or more battle difficulties. The game scene can be divided into a plurality of fighting routes which can be criss-cross, so that the players can conveniently control the virtual characters in the game scene to carry out flexible fighting.

It should be noted that, in the present embodiment, the description is given by taking an example in which the server executes the rendering method of the object, and the rendering method of the object in the present embodiment is also applicable to a case in which the server and the client execute the rendering method of the object together or the client executes the rendering method of the object separately.

The client of the battle game application can be run on the terminal equipment of the user (corresponding to an object), and the client can be in communication connection with the server, and the server is a background server of the battle game. The user can log in to the client running on the terminal equipment of the user in the modes of account number, password, dynamic password, associated application (third-party application) login and the like, and enter a one-play battle game by operating the client.

In one-play battle games, different players can control different virtual characters to execute game operations in a game scene through clients of battle games running on terminal devices of the players, and thus multi-player battles are conducted. The player can control the virtual character in the battle game to spray the spraying paint on the spraying object by using the spraying prop. The paint may be paint or other paint that can distinguish different participants, the spraying prop may be an instrument prop, a virtual object prop (e.g., a seat or a ride), and the spraying object may be a ground surface, an object surface in a game scene, and the like, which is not limited in this embodiment.

In the process of fighting games, when the virtual character controlled by the player enters the pigment sprayed by the player or the player, the virtual character can have the advantages of acceleration of movement, ammunition recovery, hidden state, rock climbing operation and the like, so that the playability of the games is improved.

In a battle game, if it is determined that the first spray paint is sprayed on the target spray object, the server may first obtain a height map of the target spray object before spraying the first spray paint, i.e., a first height map, which may be used to indicate height values of the spray paint at various positions of the target spray object before spraying the first spray paint (indicating which spray paint is present and which spray paint is absent).

The target painted object may be a target painted surface, for example, a particular surface in a target game scene, such as a floor, a wall, a surface of a target object (e.g., a box) in the scene, and so on. The first spray paint is a spray paint that is sprayed during a certain spray.

The first height map may indicate the height of the paint of each participant, and the height may be a specific height of the paint, or may indicate the presence or absence of the paint and the participant to which the paint belongs, by different marks. The first height map may be pre-stored in a specific storage space, such as a memory, a cache, and the like, which is not limited in this embodiment.

The same type of paint, e.g., paint of the same color, may be used by the avatars of the same participant, thereby facilitating each participant to distinguish paint painted by the same participant from paint painted by different participants.

It should be noted that, in the present embodiment, the height map may be an RG map, and the R channel and the G channel respectively correspond to different parties, and are used to represent height values of the sprayed paint of different parties.

Step S204, a second height map corresponding to the first spraying paint is obtained, wherein the second height map is used for representing height values of the first spraying paint sprayed on each position of the target spraying object.

After spraying the first spray paint, the server may calculate a height value of the first spray paint sprayed at each position of the target spray object, that is, a second height map, for example, from the spray position and the spray amount of the first spray paint.

Step S206, mixing the first height map and the second height map to obtain a target height map, wherein the target height map is used for representing height values of the spraying paint on each position of the target spraying object after the first spraying paint is sprayed.

After obtaining the first height map and the second height map, the server may blend the first height map and the second height map to obtain a target height map. The different height maps may be mixed by simple superposition, or by overlaying, offsetting, etc. as described above.

The paint of the same party can have a superimposed effect (height value increased from the original) or a maintained effect (height value kept constant). The height values of the spray paint of different participants may have a covering effect (new spray paint may cover the spray paint of other participants), may have a counteracting effect (new spray paint may counteract the spray paint of other participants by a certain height value), and may also have a coexisting effect (the same location may be sprayed simultaneously by the spray paint of different participants).

For example, the target object may be painted in a location that is allowed to be covered by paint from only one participant, and new paint may either cancel (existing paint disappears) or cover (new paint remains) existing enemy paint. This location may also allow for coverage by multiple participants' paint sprays, and the new paint spray may offset some of the existing enemy paint or offset all of the existing enemy paint spray and retain some of the new paint.

And S208, rendering the target spraying object according to the target height map and the target surface map, wherein the target surface map is the surface map of the target spraying object.

A renderer (Shader) on the server may render the target spray object based on the target height map and the target surface map, which is a surface map of the target spray object representing the original color of the target spray object.

Optionally, in this embodiment, when performing rendering, based on the target height map, if two height values (corresponding to different channels, e.g., R channel, G channel) of a location (pixel point) are both smaller than a threshold value, indicating that the location is not covered by the paint of any one of the participants, the original color of the target paint object at the location is displayed at the location; if only one of the two height values of a position (pixel point) is higher than a threshold value, the position is covered by the spraying paint of a certain participant, and the corresponding color is displayed at the position.

Alternatively, when it is determined whether two height values of a certain pixel satisfy a height condition (higher than a threshold) in order of priority, for example, the R channel is determined preferentially, and if both the R channel and the G channel satisfy the height condition, the color of the R channel is displayed due to the preferential determination of the R channel.

For a game scene, the rendered game pictures can be synchronized to the clients of the players participating in the battle game so as to synchronously display the same game pictures.

Through the above steps S202 to S208, a first height map corresponding to the target spraying object is obtained, where the first height map is used to represent height values of the spraying pigments at various positions of the target spraying object before the first spraying pigment is sprayed; acquiring a second height map corresponding to the first spraying paint, wherein the second height map is used for representing height values of the first spraying paint sprayed on each position of the target spraying object; mixing the first height map and the second height map to obtain a target height map, wherein the target height map is used for representing height values of the spraying paint at various positions of the target spraying object after the first spraying paint is sprayed; the method comprises the steps of rendering a target spraying object according to a target height map and a target surface map, wherein the target surface map is the surface map of the target spraying object, solving the problem that the memory resource occupation is overlarge due to the fact that an original map needs to be reserved in a pigment spraying mode in a game scene in the prior art, and reducing the memory resource occupation while not reducing the rendering quality.

As an alternative embodiment, obtaining a second height map corresponding to the first sprayed paint comprises:

s11, when it is detected that the first spray paint is sprayed onto the target spray object, acquiring a second height map corresponding to the first spray paint, wherein the first spray paint is the spray paint sprayed by the target virtual character.

Obtaining the second height map corresponding to the first spray paint may be performed after the server detects that the first spray paint is sprayed onto the target spray object, the first spray paint being the spray paint sprayed by the target avatar.

The target object (corresponding to the target player) may control the target virtual character to perform a game operation, for example, to spray a first spray paint onto the target spray object. The target virtual character may be a virtual character belonging to the first participant.

The first spraying pigment may be carried by a target bullet and sprayed on the target spraying object in a manner of scattering after explosion after colliding with the target spraying object, or thrown onto the target spraying object in a manner of throwing, which is not limited in this embodiment.

The server may detect a game operation performed by a virtual character in the battle game, for example, detect that the first paint is sprayed onto the target paint object, the first paint being paint sprayed by the target virtual character.

By the embodiment, the height map of the sprayed object after spraying is triggered and acquired by detecting the operation of the virtual object in the event scene, so that the accuracy of acquiring the height map can be improved.

As an alternative embodiment, after detecting that the first spray paint is sprayed onto the target spray object, the method further includes:

and S21, determining collision parameters of the target spraying ammunition carrying the first spraying pigment and the target spraying object, wherein the collision parameters comprise: collision point, collision force and collision direction;

and S22, controlling the first spraying pigment to be sprayed on the target spraying object by taking the collision point as an anchor point according to the collision strength and the collision direction.

If the first sprayed color is sprayed onto the target sprayed object, the effect of displaying the first sprayed color sprayed onto the sprayed object can be controlled to enhance the realism of the color spraying.

Alternatively, in this embodiment, the collision parameters of the target paint powder carrying the first paint pigment with the target paint object may be determined first, and the collision parameters may include: the collision point, the collision strength and the collision direction can also comprise the spraying amount of the first spraying pigment.

According to the collision strength and the collision direction, the first spraying paint can be sprayed on the target spraying object under the control of taking the collision point as an anchor point, for example, in order to express the effect of the fluid spreading in the air, the displacement of each vertex along with the time can be calculated according to a parabolic formula for each vertex of the first spraying paint, so that the spraying effect of the first spraying paint on the target spraying object is controlled and displayed, and the spraying area of the first spraying paint is determined.

Through this embodiment, according to collision dynamics and collision direction, use the collision point as anchor point control with spraying pigment to spraying object on, can strengthen the sense of reality of pigment spraying.

As an alternative embodiment, rendering the target spray object according to the target height map and the target surface map comprises:

s31, rendering a first spraying area of the target spraying object according to the target surface map, wherein the first spraying area is an area where the height value of the spraying pigment on the target spraying object is smaller than a target height threshold value, and the first spraying area is rendered into a color corresponding to the target surface map;

and S32, rendering a second spraying area of the target spraying object according to the target height map, wherein the second spraying area is an area where the height of the spraying pigment on the target spraying object is greater than or equal to the target height threshold, and the second spraying area is rendered into a color corresponding to the spraying pigment sprayed by the second spraying area.

When rendering the target spray object, the rendered area may be divided by a target height threshold, for example, an area where the height value of the spray paint on the target spray object is smaller than the target height threshold may be divided into a first spray area, and an area where the height value of the spray paint on the target spray object is greater than or equal to the target height threshold may be divided into a second spray area.

The target height threshold may be a height threshold for one of the sprayed paint and the height thresholds for different sprayed paints may be the same. If the spraying pigment on one pixel point is one, the height value of the spraying pigment is smaller than the target height threshold value, the pixel point belongs to a first spraying area, and otherwise, the pixel point belongs to a second spraying area. If the spraying pigment on one pixel point is multiple, if the height value of each spraying pigment is smaller than the target height threshold value, the area belongs to a first spraying area, and if not, the pixel point belongs to a second spraying area.

For a pixel point belonging to the first spraying area, since the pixel point is not covered by the spraying pigment, or the height value of the spraying pigment covering the pixel point is too small, the pixel point can be rendered according to the target surface mapping, for example, the pixel point can be rendered as the color of the pixel point in the target surface mapping.

For the pixel point belonging to the second spraying area, because the height value of the spraying pigment covering the pixel point meets the height condition, the pixel point can be rendered into the color corresponding to the spraying pigment covering the pixel point.

The rendering of the whole target spraying object can be completed by rendering different areas or different pixel points on the target spraying object.

By the embodiment, the rendering of the spraying object is controlled by configuring the threshold value of the height value of the spraying pigment, and the rationality of object spraying can be improved.

As an alternative embodiment, rendering the second painting region of the target painting object according to the target height map includes:

s41, determining the area with the height value larger than the height value of the corresponding position on the target noise map as a second spraying area;

and S42, rendering the second spraying area into a color corresponding to the spraying pigment sprayed by the second spraying area.

In order to embody the flow properties of the pigments, the height map can be adjusted by superimposing (mixing) a noise map on the height map. The mode of superposition may be: and superposing the target height map and the first noise map to obtain the superposed target height map.

For example, as shown in fig. 3, the contour of the height map on the left side is fixed without adhesion, the matching degree of the flowing property of the pigment (such as paint) is poor, and a random edge can be rendered by overlapping the noise map, so that the flowing property and the adhesion of the pigment are reflected. As shown in fig. 4, c1 is a side noise map, c2 is a side height map of c2' (height map), and c is a height map after superposition.

For the superimposed target height map (or the target height map), an area in which the height value is greater than the height value of the corresponding position on the target noise map (the second noise map may be the same noise map as the first noise map or different noise maps) may be determined as a second spraying area, and the second spraying area is rendered into a color corresponding to the spraying pigment sprayed by the second spraying area.

For example, as shown in fig. 5, for a Shader (renderer) of a building, if the height value of a pixel point is greater than a noise threshold, a paint (an example of a paint) color is displayed, otherwise, a building body color is displayed.

Through this embodiment, combine the noise map to carry out the rendering of spraying object, can improve the fidelity degree that the object was rendered, promote user's use and experience.

s51, rendering a first sub-area of the second spraying area into a first color, wherein the first sub-area is an area in the second spraying area, the height value of the spraying pigment of the first participant is greater than or equal to a target height threshold value, the first participant is a participant to which the first spraying pigment belongs in a plurality of participants of the target event, and the first color is a color corresponding to the first participant;

and S52, rendering a second sub-area of the second spraying area into a second color, wherein the second sub-area is the other area of the second spraying area except the first sub-area.

In the rendering, for a first sub-area of the second painting area, which is an area in the second painting area where the height value of the painting pigment belonging to the first participant (first competitor) is greater than or equal to the target height threshold, the painting pigment can be rendered into a color corresponding to the first participant, that is, the first color. The first party is a party to which the first sprayed paint belongs among a plurality of parties (parties) to the target event (target match game).

For each pixel point in the first sub-area, it may be covered by only the paint of the first participant, or may be covered by paint of other participants (for example, the second competitor) except the first participant, and no matter whether the height value of the paint of the other participants is greater than or equal to the target height threshold, as long as the height value of the paint of the first participant is greater than or equal to the target height threshold, the pixel point may be rendered to the color corresponding to the first participant.

Since the height value of the sprayed paint of a participant on each pixel point in the second spraying region is greater than or equal to the target height threshold, the other regions of the second spraying region except the first sub-region can be rendered into a color different from the first color, for example, the second color. The second color may correspond to a color of a participant other than the first participant (e.g., a second competitor), e.g., a second participant.

Alternatively, in order to ensure the rendering accuracy, the height value of the spraying material of only one participant allowed to be greater than or equal to the target height threshold value on one pixel point may be set. Therefore, in the target height mapping, if the height value of the paint sprayed on a pixel point belonging to the first participant is greater than or equal to the target height threshold, there are two cases: before spraying the first spraying pigment, the height value of the spraying pigment belonging to the first party on the pixel point is greater than or equal to a target height threshold value; before spraying the first spraying pigment, the height value of the spraying pigment belonging to the first participant on the pixel point is smaller than the target height threshold, and after spraying the first spraying pigment, the height value of the spraying pigment belonging to the first participant on the pixel point is larger than or equal to the target height threshold, and in any case, the rendering mode can meet the requirement of pigment coverage (new pigment covers old pigment).

For example, as shown in fig. 6, when performing rendering, rendering is performed preferentially according to the height value of the spray paint of the participant corresponding to the spray paint that is sprayed most recently, and the spray paints of other colors in a dot shape may be displayed in the spray paint of one color, so that the displayed spray paint has a higher degree of simulation.

Through the embodiment, the painting object is rendered according to the condition that the height value of the painting pigment belonging to the first party meets the threshold requirement, and the rendering rationality of the painting object can be improved.

As an optional embodiment, before rendering the second painting region of the target painting object according to the target height map, the method further includes:

and S61, adjusting the height value of the second spraying pigment in a third subarea of the second spraying area to be smaller than the target height threshold value, wherein the second spraying pigment belongs to a second participant in the plurality of participants, and the height value of the second spraying pigment in the third subarea of the second spraying area sprayed by the second spraying pigment belongs to an area where the height value of the first participant is larger than or equal to the target height threshold value.

The other participants than the first participant include a second participant, and the paint color used by the second participant is a second paint color. In the second sprayed region, the region to which the second sprayed color is sprayed is the fourth subregion. In the fourth sub-area, the height values of the sprayed pigments belonging to the first participant on part of the pixel points are greater than or equal to the target height threshold, and the height values of the sprayed pigments belonging to the first participant on part of the pixel points are less than the target height threshold.

For the part of the fourth sub-area where the height value of the paint of the first participant is greater than or equal to the target height threshold, that is, the third sub-area, in order to ensure that the condition that the height value of the paint of only one participant is allowed to be greater than or equal to the target height threshold on one pixel point (which is convenient for the renderer to render) is met, the height value of the second paint on each pixel point in the third sub-area may be adjusted to be less than the target height threshold.

Through this embodiment, through the height value of the spraying pigment of adjustment belonging to the second party, can make things convenient for the renderer to render, improve the accuracy that the object was rendered.

As an alternative embodiment, adjusting the height value of the second sprayed color within the third sub-area of the second sprayed area to be less than the target height threshold comprises:

s71, reversing the height value of the spraying paint belonging to the first party in the fourth sub-area by taking the target height threshold value as an axis;

s72, the minimum value between the inverted height value and the height value of the paint color belonging to the second party in the fourth sub-area is determined as the height value of the paint color belonging to the second party.

In order to adjust the height value of the second spraying pigment in the third sub-area to be smaller than the target height threshold, the height value of the spraying pigment belonging to the first party in the fourth sub-area may be inverted with the target height threshold as an axis, the inverted height value may be a value greater than or equal to zero, and for a value smaller than zero, the inverted height value may be uniformly configured to be zero; the minimum value between the inverted height value and the height value of the spray paint belonging to the second party in the fourth sub-area is determined as the height value of the spray paint belonging to the second party.

For example, as shown on the left side of fig. 7, a display region having a color a height value greater than or equal to the threshold value overlaps with a display region having a color B height value greater than or equal to the threshold value. The color B is the color of the newly sprayed paint, and a new color (color B) is required to cover the old color (color) in the battle in order to improve the playability of the game. If the determination logic of the renderer preferentially determines whether the height value of the color A is greater than the threshold, the overlapping area displays the color A. In order to adjust the height value of the overlap area color a to be smaller than the threshold value, the height value of the color B may be inverted with the threshold value as an axis to obtain B ', and min (a, B') may be used as the height value of the color a to obtain a display effect as shown in the right side of fig. 7.

By this embodiment, by inverting the height value of the new paint with the threshold value as the axis and taking the minimum value of the inverted height value and the height value of the paint of the other party as the height value of the paint of the other party, the rationality of the height value adjustment can be ensured.

It should be noted that, in the actual rendering process, each pixel point of the spraying object may be rendered in a sequential rendering manner, and it is not necessary to render the area after the spraying area is first divided, and the final rendering result is to render different spraying areas.

As an alternative embodiment, after obtaining the target height map corresponding to the target spraying object, the method further includes:

s81, dynamically generating a first normal map corresponding to the spraying paint on the target spraying object according to the target height map;

and S82, generating a diffuse reflection shadow for the spraying paint on the target spraying object by using the first normal map.

To enhance the display effect of the spray paint and improve the realism of the spray paint display, a normal map (i.e., a first normal map) of the spray paint may be used to generate a diffuse reflection shadow for the spray paint on the target spray object.

The paint spraying can be dynamically generated based on a target height chartlet, and in order to improve the efficiency of the normal chartlet, each pixel point in the height chart can be sampled twice, for example, the height value of the upper pixel point and the height value of the right pixel point are calculated according to the formula (1), and the normal value of the pixel point is calculated to obtain the corresponding normal chartlet:

New_Normal=(∆hx,∆hy,1-(∆hx)²+(∆hy)²) (1)

wherein, Δ hx = (tex (u, v) -tex (u +1, v)). Scale,. hy = (tex (u, v) -tex (u, v + 1)). Scale,. New _ Normal is the value of the corresponding pixel in the Normal map,. _ Scale is the specific coefficient,. tex (u, v) is the height value of the pixel (u, v) in the height map, and.New _ Normal is the value of the corresponding pixel in the Normal map.

For example, as shown in fig. 8, the left side of fig. 8 is a height map, and the right side of fig. 8 is a normal map generated based on the left height map.

For the first normal map obtained in the above manner, a diffuse reflection shadow may be generated for the spray paint on the target spray object using the first normal map, for example, a diffuse reflection shadow may be generated for the spray paint on the target spray object based on the distance between the value in the first normal map and the camera in the scene. For example, a diffuse reflection shadow can be created for the spray paint by lambert's diffuse reflection, half-lambert's diffuse reflection, or other modifications.

According to the embodiment, the normal map is generated for the spraying pigment through the height map, and the diffuse reflection shadow is generated for the spraying pigment based on the normal map, so that the display effect of the spraying pigment can be enhanced, and the reality of the display of the spraying pigment is improved.

As an alternative embodiment, after generating the diffuse reflection shadow for the paint on the target painted object using the first normal map, the method further comprises:

and S91, generating the light-reflecting bright spots for the spraying paint sprayed on the target spraying object by using the target bright spot map.

In order to enhance the display effect of the spray paint, a light reflecting bright spot for characterizing light irradiation may be displayed on the spray paint. The reflective speckles may be added on the paint spray using a speckle pattern.

For example, as shown in fig. 9, the highlight map may be a cube map, where a plurality of highlights are distributed on a cube, and the cube map is sampled (e.g., using a texCUBE function provided by Unity) to generate reflective highlights for the paint.

Through the embodiment, the light-reflecting bright spots are generated for the spraying pigment, so that the display effect of the spraying pigment can be enhanced, and the reality of the display of the spraying pigment is improved.

As an alternative embodiment, after dynamically generating the first normal map corresponding to the spraying paint on the target spraying object according to the target height map, the method further includes:

and S101, rendering by using the first normal map and the second normal map of the target spraying object so as to control and generate an animation in which the first normal of the spraying pigment sprayed on the target spraying object and the second normal of the target spraying object appear alternately.

In addition to the first normal map of the sprayed paint, the target sprayed object itself has one normal map, i.e., the second normal map, and the reality of the sprayed paint displayed on the sprayed object can be increased by fusing the normals in the two normal maps.

Optionally, in this embodiment, the first normal map and the second normal map of the target spraying object may be used for rendering to control generation of an animation in which the first normal of the sprayed paint sprayed on the target spraying object and the second normal of the target spraying object appear alternately.

For example, as shown in FIG. 10, the paint sprayed has a first normal, the ground has a second normal, and the first normal and the second normal can be controlled to alternate in the Shader, thereby generating a normal blending animation.

Through this embodiment, through the normal line of fusing spraying pigment and the normal line of spraying object, can improve the authenticity that the spraying effect shows.

The following explains a rendering method of an object in the embodiment of the present application with an optional example. In this example, the target event is a target battle game, the paint is paint, and the target object is the ground.

As shown in fig. 11, the flow of the rendering method of the object in the optional example may include the following steps:

and step S1102, detecting that the paint sprayed by the virtual character is sprayed on the ground.

In step S1106, the target spray object is rendered using the surface map, the normal map, and the height map of the floor.

The client can use the surface map of the ground, the normal map of the paint, the normal map of the ground and the height map to render the target spraying object so as to control and display the effect that games of different opponents are sprayed on the ground, wherein the normal map of the paint is obtained through dynamic calculation of the height map, and the normal map of the ground and the normal map of the paint can be subjected to normal fusion.
