Description

Technical Field

[0001] The present application relates to the field of computer technology, and in particular to a method, apparatus, computer device, and computer-readable storage medium for determining a post-processing region. Background Art

[0002] During the game development process, in order to improve the display effect of the game screen, a large number of post-processing effects will be used. Post-processing effects are further processing of the image obtained by the rendering process. For example, post-processing effects include: for stroking, for blurring, for glitch art, etc.

However, due to the large number of objects in the scene and the wide variety of parameters, performing post-processing based on the object parameters is cumbersome and time-consuming, and the processing effect is not improved, thus affecting the post-processing efficiency of the game screen.

[0052] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0053] The embodiments of the present application provide a method, apparatus, computer-readable storage medium, and computer device for determining a post-processing area. Specifically, the method for determining the post-processing area in the embodiments of the present application can be executed by a computer device. Among them, the computer device can be a terminal or a server, etc. The terminal can be a smart phone, a tablet computer, a notebook computer, a touch screen, a personal computer (PC), a personal digital assistant (PDA), and other terminal devices. The server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers. It can also be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN, and big data and artificial intelligence platforms.

[0054] For example, the computer device can be a terminal. The terminal can obtain the scaling parameter, rotation parameter, and the center point position in the world coordinate system corresponding to the target control area in the target virtual scene. The target control area is adjusted based on the scaling parameter, the rotation parameter, and the center point position; map the pixel point position of the target virtual scene in the world coordinate system to the spatial coordinate system corresponding to the target control area to obtain the mapped position of the pixel point in the spatial coordinate system; perform a rotation process on the pixel point according to the rotation parameter and the mapped position to obtain the rotated position of the rotated pixel point in the spatial coordinate system; determine the target position of the pixel point in the world coordinate system according to the center point position and the rotated position; determine the post-processing area from the target virtual scene based on the scaling parameter, the rotation parameter, the center point position, and the target position.

[0055] Based on the above problems, the embodiments of the present application provide a first method, apparatus, computer device, and computer-readable storage medium for determining a post-processing area, which can improve the post-processing efficiency of the virtual scene screen.

[0056] The following will be described in detail respectively. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments.

[0057] An embodiment of the present application provides a method for determining a post - processing area. This method can be executed by a terminal or a server. In this embodiment of the present application, the method for determining the post - processing area is described by taking the case where it is executed by a terminal as an example.

[0058] Please refer to Figure 1 , Figure 1 which is a schematic flow chart of a method for determining a post - processing area provided by an embodiment of the present application. The specific process of this method for determining the post - processing area can be as follows:

[0059] 101. Obtain the scaling parameter, rotation parameter corresponding to the target control area in the target virtual scene, and the center point position of the center point in the world coordinate system.

[0060] In an embodiment of the present application, the target virtual scene refers to a scene that simulates reality and is displayed through a terminal. For example, the target virtual scene can be a game scene. Different display effects of the target virtual scene can be achieved by rendering the target virtual scene.

[0061] Among them, the world coordinate system refers to the coordinate system used to create the target virtual scene. The target virtual scene is composed of multiple pixel points, and each pixel corresponds to a position coordinate in the world coordinate system.

[0062] Among them, the target control area refers to an area in the target virtual scene. The target control area can be set by the user. Specifically, the target control area is adjusted based on the scaling parameter, rotation parameter, and center point position. The scaling parameter can be used to adjust the size of the target control area, and the rotation parameter can be used to rotate the target control area.

[0063] For example, first determine a center point in the world coordinate system. This center point can be any coordinate point in the world coordinate system. Use this center point as the center of the target control area to be set. Then, by setting the scaling parameter and rotation parameter, generate the target control area.

[0064] 102. Map the pixel point positions of the pixel points in the target virtual scene in the world coordinate system to the spatial coordinate system corresponding to the target control area to obtain the mapped position of the pixel point in the spatial coordinate system.

[0065] Among them, the spatial coordinate system corresponding to the target control area refers to the coordinate system constructed based on the target control area, and the spatial coordinate system takes the center point position of the target control area as the coordinate origin.

[0066] In an embodiment of the present application, the world coordinate system and the spatial coordinate system can include multiple coordinate axes. For example, the world coordinate system can include: the X - axis, the Y - axis, and the Z - axis; the spatial coordinate system can include: the X’ - axis, the Y’ - axis, and the Z’ - axis.

[0067] For example, the position of the center point of the target control area in the world coordinate system can be:

[0068] (X1, Y1, Z1), and the position of the center point of the target control area in the spatial coordinate system can be: (X2, Y2, Z2), where (X1, Y1, Z1) and (X2, Y2, Z2) can be the same or different.

[0069] Specifically, mapping the pixel point position of the target virtual scene in the world coordinate system to the spatial coordinate system means obtaining the position of the pixel point in the spatial coordinate system. The position of the pixel point in the spatial coordinate system can be calculated through the position correspondence between the center point of the target control area in the world coordinate system and the spatial coordinate system, so as to obtain the mapped position.

[0070] In some embodiments, to reduce the computational complexity, the axis directions corresponding to the world coordinate system and the spatial coordinate system are parallel to each other, that is, the X-axis is parallel to the X'-axis, the Y-axis is parallel to the Y'-axis, and the Z-axis is parallel to the Z'-axis. Then, the step of "mapping the pixel point position of the target virtual scene in the world coordinate system to the spatial coordinate system corresponding to the target control area to obtain the mapped position of the pixel point in the spatial coordinate system" may include the following operations:

[0071] Calculate the difference between the pixel point position and the center point position to obtain the vector of the pixel point position relative to the center point position;

[0072] Determine the mapped position based on the vector.

[0073] Specifically, calculate the difference between the pixel point position of each pixel point in the world coordinate system and the center point position of the target control area in the world coordinate system to obtain the displacement value of each pixel point position relative to the center point, that is, the vector.

[0074] For example, the target virtual scene includes pixel point A. The pixel point position of this pixel point A in the world coordinate system can be: (aX, aY, aZ), and the center point position of the target control area in the world coordinate system can be: (X1, Y1, Z1). Calculate the difference between the pixel point position and the center point position to obtain the vector: (aX - X1, aY - Y1, aZ - Z1). According to this vector, the position of pixel point A in the spatial coordinate system, that is, the mapped position, is: (aX - X1, aY - Y1, aZ - Z1).

[0075] 103. Rotate the pixel point according to the rotation parameter and the mapped position to obtain the rotated position of the rotated pixel point in the spatial coordinate system.

[0076] Specifically, the mapped position of the pixel points mapped to the spatial coordinate system is rotated according to the rotation parameters of the target control area to obtain the rotated position of the pixel points in the spatial coordinate system.

[0077] In some embodiments, to ensure that the pixel points in the target virtual scene rotate following the target control area, the step "rotating the pixel points according to the rotation parameters and the mapped position to obtain the rotated position of the rotated pixel points in the spatial coordinate system" may include the following operations:

[0078] Determine a rotation transformation matrix according to the rotation parameters;

[0079] Calculate the product of the mapped position and the rotation transformation matrix to obtain the rotated position.

[0080] First, generate a rotation transformation matrix according to the obtained rotation parameters of the target control area, and then calculate the product of the mapped position of each pixel point and the rotation transformation matrix, that is, the rotated position of each pixel point in the spatial coordinate system can be obtained.

[0081] In some embodiments, the step "determining a rotation transformation matrix according to the rotation parameters" may include the following operations:

[0082] Generate a rotation matrix based on the rotation values in each axis direction in the spatial coordinate system to obtain a plurality of rotation matrices;

[0083] Multiply the plurality of rotation matrices to obtain the rotation transformation matrix.

[0084] Among them, the rotation parameters may include the rotation values in each axis direction of the target control area in the spatial coordinate system. For example, the coordinate axes of the spatial coordinate system include: X'-axis, Y'-axis, and Z'-axis, then the rotation parameters include: the rotation value in the X'-axis direction, the rotation value in the Y'-axis direction, and the rotation value in the Z'-axis direction.

[0085] Furthermore, according to each rotation value, generate corresponding rotation matrices respectively to obtain a plurality of rotation matrices, and then multiply the plurality of rotation matrices to obtain the rotation transformation matrix.

[0086] Among them, the rotation matrix is a matrix that changes the direction of a vector but does not change its magnitude when multiplying a vector.

[0087] Specifically, the mapped position refers to the displacement value of the pixel point position of each pixel point relative to the center point, that is, a vector. Calculating the product of the mapped position and the rotation transformation matrix, that is, calculating the product of the vector and the rotation transformation matrix, to obtain the rotated position.

[0088] 104. Determine the target position of the pixel points in the world coordinate system according to the center point position and the rotated position.

[0089] Specifically, the rotated position of each pixel point after rotation according to the rotation parameters in the spatial coordinate system is mapped to the world coordinate system to obtain the position of the rotated pixel point in the world coordinate system, that is, the target position.

[0090] In some embodiments, the step of "determining the target position of the pixel point in the world coordinate system according to the center point position and the rotated position" may include the following operations:

[0091] Calculate the sum value of the rotated position and the center point position to obtain the target position.

[0092] Specifically, add the rotated position obtained after rotating each pixel point in the spatial coordinate system to the center point position, and based on this, map the position of the rotated pixel point to the world coordinate system to obtain the target position of each pixel point after rotation in the world coordinate system.

[0093] 105. Determine the post-processing area from the target virtual scene based on the scaling parameter, rotation parameter, center point position, and target position.

[0094] Among them, the post-processing area refers to the area where post-processing is performed. Post-Process Effect is a technology for reprocessing the rendered image. For each scene image, before being drawn to the user window, the entire image is processed twice, and then the decorated image is presented to the user.

[0095] In the embodiments of the present application, when performing post-processing on the target virtual scene, in order to facilitate the user to select the post-processing area by themselves, the post-processing area can be selected from the target virtual scene according to the scaling parameter, rotation parameter, and center point position of the target control area.

[0096] In some embodiments, in order to accurately select the post-processing area, the step of "determining the post-processing area from the target virtual scene based on the scaling parameter, rotation parameter, center point position, and target position" may include the following operations:

[0097] Determine the target area in the world coordinate system based on the scaling parameter, rotation parameter, and center point position;

[0098] Determine the post-processing area from the target virtual scene according to the target area and the target position.

[0099] Specifically, determine a range of area in the world coordinate system according to the scaling parameter, rotation parameter, and center point position of the target control area, so as to obtain the target area, which can be implemented by BoxMask-3D in the material system. The logical nodes in the material system are used to define a box range according to the input.

[0100] In some embodiments, in order to select the area that needs to be post-processed, the step of "determining the post-processing area from the target virtual scene according to the target area and the target position" may include the following operations:

[0101] Determine whether the target position is within the target area to obtain a judgment result;

[0102] Determine the target pixel points from the pixel points of the target virtual scene according to the judgment result;

[0103] Form the post-processing area based on the target pixel points.

[0104] First, determine a position range according to the target area, and then determine whether the target position of each pixel point is within this position range to obtain a judgment result.

[0105] In some embodiments, the step of "determining the target pixel points from the pixel points of the target virtual scene according to the judgment result" may include the following operations:

[0106] If the judgment result indicates that the target position is within the target area, obtain the target pixel points according to the pixel points at the target position.

[0107] For example, the pixel points may include: the first pixel point, the second pixel point, the third pixel point, and the fourth pixel point, etc. Among them, the first pixel point corresponds to the first target position, the second pixel point corresponds to the second target position, the third pixel point corresponds to the third target position, and the fourth pixel point corresponds to the fourth target position. If the first target position and the second target position are within the target area, the target pixel points can be determined as: the first pixel point and the second pixel point.

[0108] Furthermore, form the post-processing area according to the first pixel point and the second pixel point.

[0109] In some embodiments, after determining the post-processing area, the method may further include the following steps:

[0110] Obtain the preset post-processing effect;

[0111] Add the preset post-processing effect to the pixel points in the post-processing area;

[0112] Wherein, the preset post-processing effect refers to the post-processing effect that is pre-designed and needs to be displayed in the target virtual scene. For example, the post-processing effect may include: image effects such as blur effect, mosaic effect, etc.

[0113] Specifically, a preset post - processing effect is added to the pixel points in the post - processing area of the target virtual scene, and the pixel points outside the post - processing area in the target virtual scene are displayed according to the previous rendering effect. In this way, post - processing of a specified area of the target virtual scene can be achieved, and the display of the post - processing effect in the specified area can be realized.

[0114] The embodiment of the present application discloses a method for determining a post - processing area. The method includes: obtaining a scaling parameter, a rotation parameter, and the center point position of the center point of the target control area in the world coordinate system in the target virtual scene, where the target control area is adjusted based on the scaling parameter, the rotation parameter, and the center point position; mapping the pixel point position of the pixel points in the target virtual scene in the world coordinate system to the spatial coordinate system corresponding to the target control area to obtain the mapped position of the pixel points in the spatial coordinate system; performing a rotation process on the pixel points according to the rotation parameter and the mapped position to obtain the rotated position of the rotated pixel points in the spatial coordinate system; determining the target position of the pixel points in the world coordinate system according to the center point position and the rotated position; determining the post - processing area from the target virtual scene based on the scaling parameter, the rotation parameter, the center point position, and the target position. In this way, the post - processing efficiency of the virtual scene picture can be improved.

[0115] According to the content introduced above, the following will give examples to further illustrate the method for determining the post - processing area of the present application. Please refer to Figure 2 , Figure 2 which is a schematic flowchart of another method for determining the post - processing area provided by the embodiment of the present application. Taking the application of this method for determining the post - processing area to a terminal as an example, the specific process can be as follows:

[0116] 201. Obtain the center point position, rotation parameter, and scaling parameter of the area culling control box created through the blueprint system.

[0117] The content of the embodiment of the present application can be implemented based on the Unreal Engine. The Unreal Engine is a complete game development platform that provides a large number of core technologies, data generation tools, and basic support required by game developers. The Unreal Engine includes a blueprint system and a material system, which are two programmable systems of the Unreal Engine. The blueprint is mainly responsible for writing and processing game business logic, and the material system is mainly responsible for shader writing and rendering processing.

[0118] Specifically, when creating an area culling control box through the blueprint system, an Actor, that is, a blueprint system Blueprint object, can be created through the blueprint system, a box is added, and a Translucent (semi - transparent) material (the transparency can be set to 0) is assigned to the box to obtain a transparent box as the area culling control box.

[0119] In the embodiments of the present application, in order to ensure that the logic for obtaining the attribute parameters of the area culling control box can be responded to both in the editor state and the running state, the logic for obtaining the attribute parameters of the area culling control box can be added after the Construction Script (blueprint constructor, which can respond to the logic in the editor state) and Tick (blueprint frame function, which can respond to the logic in the game running state) functions.

[0120] Specifically, the rotation parameter can be obtained through the Get Actor Rotation function in the blueprint system, the center point position can be obtained through GetActor Lotation, and the scaling parameter can be obtained through the Get Actor Scale function.

[0121] Among them, the rotation parameter obtained through Get Actor Rotation is represented in radians, and the D2R (DegreeToRadius, which converts the value from degrees to radians) node is required to convert the radians to degrees.

[0122] 202. Pass the center point position, rotation parameter, and scaling parameter to the material system through the material parameter set.

[0123] Among them, the material parameter set is used to transfer parameters from the blueprint to the material system.

[0124] Among them, the rotation parameter includes the rotation values in the directions of each coordinate axis in the world coordinate system. For example, the coordinate axes can include: the X-axis, the Y-axis, and the Z-axis, then the rotation parameter can include: the rotation value Roll around the X-axis direction, the rotation value Pitch around the Y-axis direction, and the rotation value Yaw around the Z-axis direction.

[0125] Specifically, through the Set Scalar Parameter Value function in the Unreal Engine, the rotation values in the directions of each axis can be passed to the MPC (Material Parameter Collection, material parameter set) respectively, and then the relative position of the blueprint Actor in the world coordinate system, that is, the center point position, can be passed to the MPC through the SetVector Parameter Value function; through the Set Scalar Parameter Value, the scaling values of the three axes of the blueprint Actor, that is, the scaling parameter, can be passed to the MPC respectively. In order to realize the real-time transfer of the position, rotation, and scaling attribute values of the area culling control box represented by the blueprint Actor into the MPC.

[0126] In terms of the MPC material parameter set, you can create six floating-point value Scalar Parameters, which are defined as the scaling values in the three coordinate axis directions and the rotation values in the three coordinate axis directions passed by the Blueprint Actor (excluding the control area box), and create a vector defined as the relative position in the world coordinate system passed by the Blueprint Actor.

[0127] 203. Rotate the pixels in the virtual scene according to the center point position and the rotation parameters through the material system to obtain the rotated position corresponding to each pixel.

[0128] First, change the material domain to PostProcess, representing a post-processing material. Then connect the main logic. The main logic is the logic of the material system shader, which controls the rendering effect. This logic is the Actor object properties passed by the Blueprint system (excluding the properties of the control area box).

[0129] Specifically, the pixel points in the virtual scene are rotated according to the center point position and the rotation parameters, that is, the pixel points in the target virtual scene are rotated and translated, thereby obtaining the rotated positions of the pixel points after rotation and translation.

[0130] In the rotation part, a Custom node (a node in the material system that can customize the shader) can be defined. Its internal logic is as follows:

[0131] According to the Roll, Pitch, and Yaw angle values passed from the MPC material parameter set, create a 3x3 rotation matrix corresponding to each angle value, and obtain three 3x3 rotation matrices;

[0132] Multiply these three rotation matrices to get the final rotation transformation matrix;

[0133] The absolute world position of the pixel in the virtual scene in the world coordinate system is subtracted from the center point position of the culling control area box passed from the MPC material parameter set to obtain the vector of the pixel's absolute world position relative to the center point position;

[0134] Multiply the vector by the rotation transformation matrix to get the pixel's absolute world position relative to the center of the culling control region.

[0135] In the translation part, its internal logic is as follows:

[0136] The relative position obtained by the above rotation is added to the absolute world position of the center point of the culling control area frame in the world coordinate system to obtain the absolute world position of each pixel point in the virtual scene after rotation and translation, that is, the rotated position corresponding to each pixel point.

[0137] 204. Determine the position range in the world coordinate system according to the center point position, rotation parameters, and scaling parameters.

[0138] Specifically, determine the boxed range, that is, the position range, according to the scaling parameters. The size of this Bounds can be defined by the scaling values in the three coordinate axes passed in by the MPC. The size values are input through this three-dimensional vector Bounds to define the boxed range and obtain the position range.

[0139] 205. Determine the target culling area from the virtual scene based on the rotated position and the position range, and superimpose the post-processing effect on the area outside the target culling area in the virtual scene.

[0140] In the embodiments of the present application, the node that defines the post-processing color output node Emissive Color is the Lerp node. The Lerp node can select the corresponding input A or B as the final output according to whether the Alpha value is 0 or 1.

[0141] For example, when the Alpha value is 0, the output content A is the post-processing stroke effect applied to the picture; when the Alpha value is 1, the output content B is the color information of the original picture.

[0142] Among them, the value of Alpha is determined by whether the rotated position is within the position range. For example, when the rotated position is within the position range, the Alpha value can be 1; when the rotated position is not within the position range, the Alpha value can be 0.

[0143] Specifically, according to the Alpha value, determine the target pixel points where the rotated position is not within the position range from the pixel points of the virtual scene. Obtain the target culling area according to the positions of the target pixel points, determine that the target culling area is the area where the post-processing effect does not need to be added, and then superimpose the post-processing effect on the area outside the target culling area in the virtual scene.

[0144] In some embodiments, a new culling control area box can also be added, and only relevant content needs to be added correspondingly in the blueprint system, MPC, and material system. The details are as follows:

[0145] Regarding the MPC material parameter set: Add 6 floating-point values and 1 vector value, including the scaling size values of the XYZ three axes of the control area, the Roll, Pitch, and Yaw angle values of the rotation, and the center point position value of the control area. Regarding the control area blueprint: Duplicate one more control area blueprint Actor. The basic logic does not need to be changed, and the transparent material does not need to be changed either. Only the name of the value passed to the MPC in the logic (the 7 values added above) needs to be changed.

[0146] In terms of post - processing materials: Copy the same logic, change the names of the values received from the MPC (the 7 values added above), multiply the result by the result of the previous operation to obtain a new value for controlling Alpha. By simply copying and changing the parameter names, a new control area can be added, and the expansion effect is good.

[0147] In some embodiments, please refer to Figure 3 , Figure 3 which is a schematic diagram of an application scenario of a method for determining a post - processing area provided by an embodiment of the present application. Figure 3 The shown user operation interface allows the user to set the culling area. Among them, the user operation interface includes a partial virtual scene and area adjustment controls. The user can set the culling area through the area adjustment controls. The area adjustment controls can be located at any coordinate point in the coordinate space of the virtual scene. Specifically, the user can adjust the size of the culling area in each axis by operating the indication icons of each axis of the area adjustment controls. For example, in Figure 3 , the user obtains a target culling area (i.e., Figure 3 the white dashed - line area) through the operation of the area adjustment controls. The target culling area is the area in the virtual scene that does not need to be post - processed.

[0148] Furthermore, please refer to Figure 4 , Figure 4 which is a schematic diagram of another application scenario of a method for determining a post - processing area provided by an embodiment of the present application. After determining the target culling area, when rendering the post - processing effect for the virtual scene, no post - processing operation is required for the objects in the target culling area. That is, in Figure 4 , post - processing operations are performed on the areas outside the target culling area in the virtual scene, and according to user requirements, post - processing operations are customized for some objects in the virtual scene.

[0149] An embodiment of the present application discloses a method for determining a post - processing area, which includes: obtaining the center point position, rotation parameters, and scaling parameters of the area culling control box created through the blueprint system, transmitting the center point position, rotation parameters, and scaling parameters to the material system through the material parameter set, rotating the pixel points in the virtual scene by the material system according to the center point position and rotation parameters to obtain the rotated positions corresponding to each pixel point, determining the position range in the world coordinate system according to the center point position, rotation parameters, and scaling parameters, determining the target culling area from the virtual scene based on the rotated positions and the position range, and superimposing the post - processing effect on the areas outside the target culling area in the virtual scene. In this way, the post - processing efficiency of the virtual scene image can be improved.
