First, a virtual scene according to an embodiment of the present application will be described.
A virtual scene is a screen that an application program displays (or provides) when running on a terminal or a server. Optionally, the virtual scene is a simulation environment for the real world, or a semi-simulated semi-fictional virtual environment, or a purely fictional virtual environment. The virtual environment may be sky, land, sea, etc., wherein the land includes environmental elements such as deserts, cities, etc.

The specific flow of the specific fluid effect processing method provided by the embodiment of the application can be as follows, as shown in fig. 1:
101. and acquiring scene data in the rendering buffer zone, and mapping coordinates of screen pixels into a three-dimensional space according to lens information of virtual lenses in the scene data and depth information corresponding to the screen pixels.
The rendering buffer may be a buffer for buffering scene data required for rendering the virtual scene, and in the embodiment of the present application, a scene with no fluid effect added may be rendered based on the scene data, and the virtual scene in step 105 is a scene with a fluid effect added.
A scene image may be obtained by rendering, which may also be referred to as a screen rendering, and displaying the scene image by a display device may present a virtual scene, so that a color to be displayed by each pixel on the display device depends on a corresponding pixel in the scene image.
The virtual lens can be regarded as an observation view angle in the three-dimensional scene, determines a part of the rendered scene in the three-dimensional scene, and renders the part of the scene to obtain the virtual scene in the embodiment of the application.
The purpose of mapping the screen pixels to the three-dimensional space is to decompose the distance between the screen pixels and the virtual camera into horizontal distances and increase the difference between the distances between different screen pixels and the virtual lens, so the three-dimensional space may be a space corresponding to the three-dimensional scene where the virtual scene is observed or may be another three-dimensional space.
The lens information of the virtual lens may include a conversion matrix which may convert a conversion relationship between a two-dimensional coordinate system corresponding to the scene image and a three-dimensional coordinate, so that the two-dimensional coordinate of the screen pixel may be converted into a three-dimensional coordinate in a three-dimensional space by the virtual lens information and the depth information of the screen pixel, and a coordinate component with respect to a coordinate axis perpendicular to a horizontal plane in the three-dimensional coordinate may represent a height of the screen pixel point in the three-dimensional space.
102. And calculating the target horizontal observation distance between the screen pixel and the virtual lens according to the three-dimensional coordinates of the screen pixel in the three-dimensional space.
For example, the three-dimensional coordinates are represented by (x, y, z), where x and y are coordinate components (hereinafter referred to as first coordinate components) of the three-dimensional coordinates projected onto a horizontal plane, and y is a coordinate component (hereinafter referred to as second coordinate components) projected onto a coordinate axis perpendicular to the horizontal plane.
The lens information of the virtual lens may further include three-dimensional coordinates of the virtual lens in the three-dimensional space, and the target horizontal observation distance between the screen pixel and the virtual lens may be a distance between projection of the screen pixel on a horizontal plane of the three-dimensional space and projection of the virtual lens on the horizontal plane, so the target horizontal observation distance may be calculated from the first coordinate component.
Assume that the three-dimensional coordinates of the virtual lens are (x 1 ,y 1 ,z 1 ) Three-dimensional coordinates (x 2 ,y 2 ,z 2 ) The target horizontal observation distance is
103. The target height of the screen pixels in three-dimensional space is determined from the three-dimensional coordinates.
For example, the height of the screen pixel in the three-dimensional space, i.e., the target height, may be determined from the second coordinate component of the screen pixel, assuming that the three-dimensional coordinates of the virtual lens are (x 1 ,y 1 ,z 1 ) Three-dimensional coordinates (x 2 ,y 2 ,z 2 ) Target height h=z 2 。
104. And determining target display parameters of the fluid special effects under the target horizontal observation distance and the target height based on a preset relation between the display parameters of the fluid special effects and the horizontal observation distance and the height.
The fluid effect may include a liquid effect and a gas effect, for example, a fog effect, a smoke effect, or a cloud effect, and the display parameter may include a parameter capable of adjusting a display effect of the fluid effect in the virtual scene, for example, the display parameter may include a concentration, a color, and the like.
The fluid special effect can be a fog special effect, the display parameters corresponding to the fog special effect can comprise concentration, color, density and the like, and through setting the density, the concentration and the color, the states of fog at different positions in the virtual scene can be different, so that the fog at the near view, the middle view and the far view in the virtual scene can be different, and the depth of field sense is created, namely in an embodiment, the fluid special effect is the fog special effect, and the display parameters comprise at least one of the fog concentration, the fog color and the fog density.
In the exponential high fog special effect, the farther the distance is, the more dense the fog is, which can cause some distant objects to be completely submerged in the fog, the user cannot observe the layout of the virtual scene, and the exponential high fog special effect is to determine the fog concentration according to the linear distance between the screen pixel point and the virtual lens, in some visual angles, for example, when looking at a high place, the difference of the linear distance between the screen pixel and the virtual lens in the virtual scene is smaller due to the higher virtual lens, and the scene depth effect of the fog special effect rendered based on the linear distance is poor.
In the embodiment of the application, the display parameters are determined according to the horizontal observation distance and the height, so that the difference between the display parameters of the screen pixels in the virtual scene about the special effect of the fluid can be increased.
The preset relation between the display parameter of the fluid special effect and the horizontal observation distance and the height can comprise a mapping relation between the combination of the horizontal observation distance and the height and the display parameter, for example, the horizontal observation distance a-height b corresponds to the display parameter c, and further, the target display parameter corresponding to the screen pixel can be determined according to the mapping relation, the target horizontal observation distance and the target height.
Optionally, the preset relationship between the display parameter of the fluid special effect and the horizontal observation distance and the height may be a relationship between the horizontal observation distance and the display parameter, and a relationship between the height and the display parameter, the relationship between the horizontal observation distance and the display parameter may be a proportional relationship between the horizontal observation distance and the display parameter, or may be other relationships that enable the virtual scene to present a larger horizontal observation distance, and the display effect of the fluid special effect is more obvious, while the relationship between the height and the display parameter may enable the screen pixels with the same horizontal observation distance and different heights in the virtual scene, and the display effects of the fluid special effect are different.
For example, the minimum height and the maximum height in the screen pixels with the same horizontal observation distance can be determined, the height drop under the same horizontal observation distance is obtained based on the difference between the maximum height and the minimum height, then the duty ratio of the difference between the maximum height and the height of each screen pixel to the height drop under the same horizontal observation distance is calculated, the duty ratio is used as a weight, and the display parameters are adjusted.
Optionally, the display parameters may be adjusted according to a scene layout in the virtual scene, for example, for determining a terrain distribution in the three-dimensional scene according to a terrain map of the three-dimensional scene corresponding to the virtual scene, the concentrations of the screen pixels belonging to the terrain may be adjusted according to the features of different terrains, so that the virtual scene may exhibit a staggered effect in the fluid special effect, that is, in an embodiment, the step of determining, based on a preset relationship between the display parameters of the fluid special effect and the horizontal observation distance and the height, the target display parameters of the fluid special effect under the target horizontal observation distance and the target height includes:
Acquiring scene layout information corresponding to a virtual scene, wherein the scene layout information comprises distribution positions of scene objects forming the virtual scene in a three-dimensional space and corresponding special effect heights;
determining the height of the target special effect corresponding to each screen pixel according to the distribution position and the three-dimensional coordinates of each screen pixel;
determining the distance display parameter of the fluid special effect for each screen pixel according to the corresponding relation between the display parameter and the horizontal observation distance in the preset relation and the target horizontal observation distance of each screen pixel;
and adjusting the distance display parameters according to the height relation between the target special effect height and the target height corresponding to each screen pixel to obtain the target display parameters of each screen pixel.
The scene layout information may indicate distribution conditions of different scene objects in the three-dimensional scene corresponding to the virtual scene and corresponding special effect heights, that is, the scene layout information may include distribution positions of the scene objects in the three-dimensional space in the virtual scene and corresponding special effect heights.
The scene object may be an object constituting a three-dimensional scene, such as an urban, a tall building, a mountain, a plateau, a plain, etc., and the special effect height may be an effective height at which the fluid special effect acts on the scene object, i.e., no fluid special effect is provided for screen pixels exceeding the effective height of the scene object.
In an embodiment, the scene layout information may reflect a distribution situation of a three-dimensional scene corresponding to the virtual scene on a horizontal plane, for example, the scene layout information includes a correspondence between coordinates and scene objects, and then, the scene object corresponding to a point in the three-dimensional scene may be determined according to the coordinates obtained after the point is projected to the horizontal plane.
The scene layout information may be generated when constructing a three-dimensional scene, and may be in different data forms, for example, may be a scene layout map.
In an embodiment, the pixel values of the pixels in the scene layout are used to represent the corresponding scene object, and the corresponding image pixels can be found in the scene layout according to the first coordinate component of the screen pixels, and the correspondence between the screen pixels and the image pixels of the scene layout can be one-to-one or many-to-one. According to the pixel value of the image pixel, determining a scene object to which the screen pixel belongs in the three-dimensional scene, and taking the special effect height corresponding to the scene object as the target special effect height corresponding to the screen pixel.
Optionally, a relationship between the corresponding special effect height and the target horizontal observation distance may be set for each scene object, and the relationship between the special effect height and the target horizontal observation distance may be a pow curve, specifically may be y=x p Wherein x is a horizontal observation distance, y is a special effect height, and p is a parameter for controlling the shape of a curve.
In another embodiment, the pixel values of the pixels in the scene layout are used to represent the special effect heights, for example, the special effect heights of different scene objects are different, the distribution condition of the scene objects corresponding to the different special effect heights in the three-dimensional space can be determined through the pixel values of the pixels in the scene layout, the corresponding image pixels of the screen pixels in the scene layout can be determined according to the first coordinate components of the screen pixels and the scene layout, and the special effect heights indicated by the pixel values of the image pixels are used as the target special effect heights corresponding to the screen pixels.
The special effect heights corresponding to different scenes can be adjusted according to the horizontal observation distances, so that in the virtual scene, for the same scene object, the part exposed by the scene object with the shorter horizontal observation distance is less, and the part of the scene object line with the longer horizontal observation distance is less, namely in an embodiment, the step of determining the target special effect height corresponding to each screen pixel according to the distribution position and the three-dimensional coordinate of each screen pixel can specifically include:
determining a scene object where each screen pixel is located according to the three-dimensional coordinates and the distribution position of each screen pixel;
Obtaining candidate special effect heights of each screen pixel according to the special effect height of the scene object where each screen pixel is located;
and adjusting the corresponding candidate special effect height according to the target horizontal observation distance of each screen pixel to obtain the corresponding target special effect height of each screen pixel.
For example, according to the scene layout information and the three-dimensional coordinates of the screen pixels, the scene object where the screen pixels are mapped to the three-dimensional space can be determined, the special effect height of the scene object is used as a candidate special effect height, the horizontal observation distance of the screen pixels is used as a weight factor, and the candidate special effect height is adjusted to obtain a target special effect height, so that for the scene object with the same scene object, the closer the horizontal observation distance is, the target special effect height is lower, and the more the scene object with the closer horizontal observation distance is, the more parts are not blocked by the fluid special effect.
And determining the corresponding distance display parameter under the target horizontal observation distance according to the relation between the horizontal observation distance and the display parameter in the preset relation.
If the target height is smaller than the special effect height, the target height can be used as the weight for adjusting the distance display parameter, and the larger the target height is, the smaller the corresponding weight is, so that the display effect of the fluid special effect is gradually weakened along with the increase of the height; if the target height is larger than the special effect height, the distance display parameter is adjusted to a value which enables the fluid special effect to have no corresponding display effect, the target display parameter is obtained, the gradual change effect of the fluid special effect on the height can be achieved, and the top of the scene object is not shielded.
Optionally, the height difference may be used as a weight for adjusting the distance display parameter, where the greater the height difference, the greater the corresponding weight, and the more obvious the display effect of the fluid special effect is at the position with lower bit effect height, that is, in an embodiment, the step of adjusting the distance display parameter according to the height relationship between the target special effect height and the target height corresponding to each screen pixel to obtain the target display parameter of each screen pixel may specifically include:
calculating the height difference between the target special effect height and the target height of each screen pixel;
and adjusting the distance display parameters according to the ratio of the height difference of each pixel to the target special effect height to obtain target display parameters.
For example, the target height is subtracted from the special effect height to obtain a height difference between the special effect height and the target height, and then the distance display parameter is adjusted based on the height difference, so that the display effect is more obvious when the fluid special effect is lower in height. And when the height difference is smaller than zero, namely the target height is higher than the special effect height, the distance display parameter is adjusted to a value which enables the fluid special effect to have no corresponding display effect, so that the target display parameter is obtained, the top of the scene object is not blocked by the fluid special effect, the scene object can be displayed in the virtual scene, the fluctuation of the scene object is observed in the virtual scene, and the near view and the distant view in the virtual scene can be distinguished.
In an embodiment, the fluid special effect is a fog special effect, and the display parameters may include fog concentration, fog density, and fog color, for example, the fog display effects at different positions in the virtual scene may be different by adjusting the fog concentrations corresponding to different screen pixels; the method can also be that the fog density is fixed, the fog density is adjusted, so that the fog display effects of different positions in the virtual scene are different, and in addition, the far and near views can be distinguished through color adjustment.
In an embodiment, the fog concentration and the fog color can be adjusted according to the horizontal observation distance and the horizontal observation height of the screen pixels, and the fog concentration can be adjusted, so that the fog concentrations at different positions in the virtual scene are different, and the colors are different. Optionally, the fog concentration can be adjusted according to the horizontal observation distance and the height of the screen pixels, and then the corresponding fog colors in different horizontal observation distance ranges and the corresponding fog colors in different height ranges are divided to adjust the fog concentration and the fog colors.
105. Rendering is carried out based on the target display parameters corresponding to the screen pixels and scene data, and a virtual scene with a fluid special effect and a depth sense is obtained.
For example, the virtual scene added with the fluid special effect can be rendered according to the target display parameters and the scene data corresponding to the screen pixels, and since the step 104 adjusts the display parameters of the fluid special effect according to the horizontal observation distance and the height, the depth of field change in the virtual scene can be distinguished and the height fluctuation of the scene object in the virtual scene can be observed through the display effect of the fluid special effect, so that the depth sense created by the virtual scene can be represented as shown in fig. 2.
The virtual scene can be further provided with an illumination effect, illumination parameters of the fluid special effects of each screen pixel can be obtained through calculation according to an illumination model, such as a BRDF reflection model, the illumination parameters can represent light receiving positions of the fluid special effects in the virtual scene, shadow positions of the fluid special effects can be calculated, and the illumination parameters can comprise colors corresponding to illumination.
According to the target display parameters of the light receiving positions, the illumination parameters are respectively adjusted, for example, the target display parameters and the illumination parameters are multiplied to realize the fluid special effect, so that the light receiving effect can be shown, if the target display parameters indicate that the corresponding positions do not have the fluid special effect, the illumination parameters can be adjusted to the parameters indicating that the illumination effect does not exist through the target display parameters, the illumination is realized to act on the fluid special effect, and similarly, the fluid special effect can have the shadow effect.
The embodiment of the application can render the virtual scene in a delayed rendering mode and the like, and if the delayed rendering mode is adopted, the calculation results (including data such as illumination parameters and the like) of the light receiving and shadow receiving (shadow receiving) of the virtual scene can be obtained from the buffer zone corresponding to the delayed rendering mode.
Optionally, the near-field fluid special effect may be eliminated according to the depth information, that is, in an embodiment, the step of rendering based on the target display parameter and the scene data corresponding to the screen pixel to obtain a virtual scene with the fluid special effect and the depth feel may specifically include:
selecting a target screen pixel from the screen pixels according to the depth information, wherein the target screen pixel corresponds to a near-field region of the virtual scene;
adjusting target display parameters of target screen pixels to eliminate the display effect of the fluid special effect in a close-range area;
rendering is carried out according to the adjusted target display parameters and scene data, and a virtual scene is obtained.
For example, the depth information indicates a straight line distance between a screen pixel and a virtual lens in a three-dimensional space, a near-view region in the virtual scene may be determined according to the depth information, for example, a depth threshold may be set, and a screen pixel within a range smaller than the depth threshold among screen pixels for displaying the virtual scene is taken as a target screen pixel, which is applied to the near-view region in the virtual scene.
And adjusting the target display parameters of the target screen pixels again to eliminate the fluid special effects of the near-field region in the virtual scene.
Rendering according to the adjusted target display parameters of the target screen pixels, the display parameters of other screen pixels and scene data to obtain a virtual scene.
The virtual scene may be a game scene for a player to play a game, in some games, the visible range of the player is blocked by the foggy, for example, as shown in fig. 3, the foggy is tiled in the game scene, and part of the scene in the game map is blocked to show the player that the current operation is equivalent, but the foggy is irrelevant to the topography, and the fog presenting effect is poor.
Obtaining a target special effect mask map for shielding a visible range of a game player in a virtual scene;
adjusting the target display parameters according to the pixel values of the pixels in the target special effect mask image;
Rendering is carried out based on the adjusted target display parameters and scene data, and a virtual scene with a fluid special effect and a depth sense is obtained.
The target special effect mask diagram is used for shielding the visible range of the player in the virtual scene, so that only part of scenes relevant to the player are displayed in the virtual scene.
