Based on one or more of the above problems, in this exemplary embodiment, there is provided a game scenario generation method, which may be executed on a device terminal, where the device terminal may include a PC end, a mobile end, and the like; of course, those skilled in the art may also operate the method of the present invention on other platforms as required, and this is not a particular limitation in the present exemplary embodiment.

and S140, rendering the first scene element, the second scene element and the target third scene element according to the rendering groups and the rendering levels corresponding to the first scene element, the second scene element and the target third scene element to obtain a target game scene.

According to the game scene generation method, on one hand, first scene elements included in a game scene are obtained, and the first scene elements are subjected to preset processing to obtain second scene elements taking the first scene elements as light sources; acquiring a third scene element included in the game scene and a pixel corresponding to the third scene element, and calculating a gradient value of the pixel; obtaining edges of the third scene elements according to the gradient values and the normalized depth values of the second scene elements, and superposing the edges and the second scene elements to obtain target third scene elements; rendering the first scene element, the second scene element and the target third scene element according to a rendering group and a rendering level corresponding to the first scene element, the second scene element and the target third scene element to obtain a target game scene, and determining the display sequence of the scene elements in the game scene according to the rendering group and the rendering level of the scene elements in the game scene instead of determining the shielding relation of the scene elements by using depth buffering in a 3D scheme, so that transparent pixels and saw teeth do not exist at the edges of the scene elements, and the performance consumption of rendering is reduced; on the other hand, as the second scene elements are normalized, the scene elements included in the game scene are converted into texture maps, the scene elements are displayed through the rendering groups and the rendering levels corresponding to the texture maps, and the advantages of the 2D scheme and the 3D scheme are combined, so that the resource consumption of rendering calculation is reduced, the rendering efficiency is improved, and meanwhile, the rendering effect is improved, so that the game scene has immersion feeling and reality feeling.

Hereinafter, each step involved in the game scene generation method of the exemplary embodiment of the present disclosure is explained and explained in detail.

First, an application scenario and an object of the exemplary embodiment of the present disclosure are explained and explained.

Specifically, the embodiment of the disclosure may be used for a game client of a user, and after the user enters a game scene, the light rays of scene elements included in the game scene may be adjusted according to illumination changes at different positions in the game scene, so that the immersion and realism of the game scene are improved.

According to the embodiment of the invention, the texture map obtained after the scene element normalization is used as a basis, the texture maps of different scene elements are processed to obtain the target scene elements, the display sequence of each scene element in the game scene is determined according to the rendering group and the rendering level of the target scene elements in the game scene, and the scene elements are rendered according to the sequence, so that the resource consumption of rendering calculation is reduced, the rendering effect of the game scene is improved, and the game scene has immersion and reality. The specific reasons are as follows: on the one hand, the texture map of the first scene element is obtained, the texture map of the first scene element is used as a light source, a plurality of texture maps corresponding to the texture map of the first scene element are shifted, the shifting direction is opposite to the direction of the light source, so that the light beam map taking the first scene element as the light source is obtained, and the sense of reality of the second scene element when being displayed in a game scene is improved; on the other hand, the rendering group and the rendering level of the scene element in the game scene are determined, and the display relation of the scene element in the game scene is determined according to the rendering group and the rendering level of the scene element instead of using depth buffering, so that transparent pixels can exist at the edge of the scene element, and meanwhile, saw teeth are not generated, thereby reducing the resource consumption of rendering calculation.

Next, explanation and explanation are made of a game scene display system involved in an exemplary embodiment of the present disclosure. Referring to fig. 2, the game scene display system may include: a game character generation module 210, a map acquisition module 220, a shader 230, and a user client 240. Wherein, the game role generation module 210 is configured to generate a third scene element included in the game scene, that is, a game role, using the 2D skeletal animation editing tool, where the generated third scene element is a texture map of the third scene element; the map obtaining module 220 is connected to the game role generating module 210 in a network manner, and is configured to obtain a texture map of a scene element included in a game scene, and normalize a depth value of the stereoscopic scene element when the game scene includes the stereoscopic scene element, thereby obtaining the texture map of the stereoscopic scene element; a shader 230, which is connected to the map obtaining module 220 in a network manner, and is configured to determine a display order of the scene elements according to a rendering group and a rendering level of the texture map of each scene element in the game scene, and render the scene elements according to the display order; the user client 240 is connected to the shader 230 in a network manner, and is used for displaying the rendered scene elements.

Hereinafter, the steps S110 to S140 will be explained and described in detail with reference to fig. 2.

In step S110, a first scene element included in a game scene is acquired, and a preset process is performed on the first scene element, so as to obtain a second scene element using the first scene element as a light source.

Wherein, the game scene can comprise one or more scene elements; the preset processing is to offset the first scene element; the first scene element is a light source, which may be a natural light source, for example: sun, flame, lightning, etc., may also be artificial light sources, such as: a lighted candle, a lighted electric lamp, or the like, the light source is not particularly limited in this example embodiment; the preset processing of the first scene element may be: performing offset processing on the first scene element along the direction of generating the light beam when the first scene is a light source; the second scene element is a beam map generated by taking the first scene element as a light source.

In the present exemplary embodiment, acquiring a first scene element included in a game scene includes:

By converting the stereoscopic scene elements into normalized texture maps, the computational performance consumption in rendering is reduced. Specifically, firstly, obtaining depth values of three-dimensional scene elements included in a game scene, wherein the depth values are distances between pixel points and a camera in a three-dimensional world, and the greater the depth values, the more distant the pixel points are from the camera; secondly, carrying out normalization processing on the depth values of the scene elements to obtain a game scene normalized texture map, wherein in the game scene normalized texture map, the maximum depth value is 1, the minimum depth value is 0, and in the normalized texture map, the scene element with the maximum depth value can be positioned at the center of the texture map, or the scene element with the minimum depth value can be positioned at the center of the texture map, and the specific limitation is not made in the example; and determining the texture map belonging to the first scene element in the normalized texture map of the game scene, namely the texture map belonging to the light source according to a preset depth threshold after obtaining the normalized texture map of the game scene, wherein the preset depth threshold can be 0.9 or 0.8, and the preset depth threshold is not particularly limited in the application.

Referring to fig. 3, after obtaining the texture map of the first scene element included in the game scene normalized texture map, that is, the texture map of the light source, the second scene element may be generated according to the first scene element, which may specifically include step S310 and step S320:

In step S310, one or more first target scene element maps corresponding to the maps of the first scene element are generated;

In step S320, it is determined that the direction of the light beam generated when the first scene element is the light source is the first direction, and the one or more first target scene element maps are subjected to preset processing based on the first direction, so as to obtain a map of a second scene element using the first scene element as the light source.

Hereinafter, step S310 and step S320 will be explained and explained. Specifically, the second scene element is a light beam map generated when the first scene element is a light source, so when the second scene element is generated, firstly, one or more texture maps corresponding to the first scene element need to be generated according to the texture maps of the first scene element, wherein, in order to enable the generated second scene element to have a sense of reality and immersion, when the number of the generated texture maps is 1, the width and the height of the texture maps are larger than those of the first scene texture maps, when the number of the generated texture maps is multiple, the width and the height of each texture map are different and have increasing trend, for example, when the width and the height of two texture maps and the first scene element are respectively 5 pixels and 7 pixels, the width and the height of the generated first texture map can be: 7 pixels, 9 pixels; the width, height of the second texture map may be: the specific width and height of the generated texture map is not limited in this example, but needs to be in an increasing trend, and one skilled in the art can set different widths and heights for different texture maps as needed.

Secondly, after obtaining the texture map of one or more scene elements corresponding to the first scene element, determining a direction of a light beam formed by the one or more scene elements, that is, determining the direction of the light beam generated when the first scene element is a light source, and after determining the direction of the light beam generated when the first scene element is a light source, offsetting the texture map of the one or more scene elements generated according to the direction of the light beam to obtain a texture map of the second scene element, wherein an offset distance between the plurality of texture maps generated in the texture map of the second scene element may be a fixed value or an arbitrary value, which is not limited in this embodiment.

In step S120, a third scene element included in the game scene and a pixel corresponding to the third scene element are acquired, and a gradient value of the pixel is calculated.

Wherein the third scene element is a game character included in the game scene, the game character may be drawn by using a spine (2D skeletal animation editing tool for the game), in order to save computation consumption in rendering, one or more game characters included in the game scene are drawn on a rendering target (RENDER TARGET), wherein the rendering target is a feature of a graphics processing unit, the rendering target is allowed to render the stereoscopic scene to a storage buffer or a rendering target texture, and then the rendering target texture is processed by a shader so as to apply other effects to the final image before the final image is displayed, and a texture map of the game character drawn by using the spine generates a transparency value; the gradient value of the pixel corresponding to the third scene element is calculated, that is, edge detection is performed on the third scene element, and a Sobel (Sobel) edge detection operator may be adopted, a Prewitt (edge detection of first-order differential operator) edge detection operator may be adopted, a Roberts (searching for an edge by using a local differential operator) edge detection operator may be adopted, and the edge detection algorithm is not particularly limited in this example.

In this exemplary embodiment, referring to fig. 4, a third scene element and a pixel corresponding to the third scene element are acquired, and a gradient value of the pixel is calculated, including step S410 and step S420:

in step S410, a map of the third scene element included in the game scene and a target pixel of the map of the third scene element in the game scene are acquired;

In step S420, a pixel within the preset range of the target pixel is determined, and a convolution calculation is performed according to the transparent value of the pixel within the preset range of the target pixel, so as to obtain a gradient value of the target pixel.

Hereinafter, step S410 and step S420 will be explained and explained. Specifically, firstly, all game characters are drawn on a blank rendering target to be used for extracting the edge information of the game characters; secondly, acquiring pixel information of the game character, and performing convolution calculation according to the transparent value of the pixel included in the preset range of the pixel, wherein the preset range can be a 3*3 range taking the target pixel as the center or a 4*4 range taking the target pixel as the center, and the preset range is not specially limited in the example. For example, when the edge detection algorithm is a Sobel operator and the preset range is 3*3 ranges centered on the target pixel, since Sobel filtering is to check the gradient change of color or brightness in the first order direction, two convolutions are required in the horizontal and vertical directions, and the two convolution kernels are respectively:

Wherein, a is 3*3 matrix composed of pixels included in the preset range of the target pixel, the value of the matrix a is the transparent value of the pixels included in the preset range of the target pixel, G _x represents the approximate value of gray scale bias in the horizontal direction, and G _y represents the approximate value of gray scale bias in the vertical direction. After G _x and G _y are obtained, an approximate gradient G, i.e., a gradient value of the target pixel, can be obtained from G _x and G _y.

In this example embodiment, the pointing of the third scene element is guaranteed to be located on the edge of the third scene element texture map by using the transparency values of the pixels included in the preset range instead of the depth values.

In step S130, according to the gradient value and the normalized depth value of the second scene element, an edge of the third scene element is obtained, and the edge and the second scene element are overlapped to obtain a target third scene element.

The gradient value is the approximate gradient obtained in step S120, the normalized depth value of the second scene element is the normalized depth value of the second scene element which is the same as the depth value of the third scene element, the edge of the third scene element is the place where the brightness changes significantly in the texture map, and the edge and the second scene element are superimposed, i.e. the edge pointing of the game character is superimposed on the texture map of the second scene element.

In this exemplary embodiment, referring to fig. 5, according to the gradient value and the normalized depth value of the second scene element, an edge of the third scene element is obtained, which includes steps S510-S530:

In step S510, a depth value of the third scene element is obtained, and a second scene element corresponding to the depth value of the third scene element is determined according to the depth value of the third scene element;

in step S520, calculating a product between a normalized depth value of the second scene element corresponding to the depth value of the third scene element and the gradient value of the pixel;

in step S530, when the product is greater than a preset gradient threshold, the pixel is an edge of the third scene element.

Hereinafter, step S510 to step S530 will be explained and explained. Specifically, first, determining a depth value of a pixel included in a game character in a game scene, and simultaneously determining a pixel of a second scene element corresponding to the depth value of the pixel included in the game character and a normalized depth value of the pixel of the second scene element; secondly, calculating the product between the gradient value of the pixel included in the game role and the normalized depth value of the pixel of the second scene element, and when the product is larger than a preset gradient threshold, considering the pixel included in the game role as the edge of the game role, wherein the preset gradient threshold can be 0.8 or 0.9, and the preset gradient threshold is not particularly limited in the example.

In this exemplary embodiment, referring to fig. 6, a target third scene element is obtained, and the game scene generating method further includes steps S610 to S640:

in step S610, attribute information of the third scene element is acquired, where the attribute information includes a width and a height of the third scene element;

In step S620, the game scene where the third scene element is located is divided according to the attribute information, so as to obtain a first scene area; the third scene element is located in the first scene area, and the first scene area comprises a plurality of first control points and a plurality of second control points;

In step S630, the colors of the plurality of first control points are obtained, and positive film-overlapping and bottom-overlapping mixing are performed on the colors of the plurality of first control points and the colors of the third scene element;

in step S640, the colors of the plurality of second control points are obtained, and the colors of the third scene element obtained by the feature film bottom-overlapping mixing and the colors of the plurality of second control points are divided and mixed to obtain the target third scene element.

Hereinafter, step S610 to step S640 will be explained and explained. Specifically, the game scene where the third scene element is located is divided, the rectangular area of the game character in the game scene texture map can be determined according to the width and the height of the game character, the rectangular area of the game character in the game scene can be adjusted through the editor, and the division mode of the game scene is not specifically limited in this example. The adjusting of the light of the second scene element included in the game scene may include: firstly, a third scene element, namely the width and the height of a game character, included in a game scene, and determining a rectangular area of the game character in the game scene according to the width and the height of the game character; secondly, setting a plurality of first control points and a plurality of second control points based on the rectangular area, wherein each control point is provided with a color, and the first control points comprise color gradual changes of the colors provided by the plurality of control points; the number of the control points included in the first control point and the second control point is not less than 2; thirdly, acquiring a plurality of colors included in the first control point, and mixing the gradient colors of the plurality of control points included in the first control point onto the game character in a positive overlapping mode, wherein a positive overlapping formula can be as follows:

final_color＝float4(lerp(color.xyz,color.xyz*blend_color.xyz,float3(blend_color.w)),color.w)

The final_color is the color of the game role obtained after the positive film is overlapped; four components of color: the red, green, blue, and transparent values may be represented by x, y, z, w, respectively, or may be represented by other labels, which are not particularly limited in this example; lerp is an interpolation function that can be used when in a game scene in order to have a buffering effect on the light of a game character; color, xyz, color, w represent color components of the game character pixel points, and blend_color, w represent color components of the first control point corresponding to the game character pixel points; finally, a plurality of colors included in the second control point are obtained, the colors of the plurality of control points included in the second control point are overlapped on the game role which is overlapped by the positive film in a dividing and mixing mode, so that the brightness of the game role is adjusted, wherein the dividing and mixing formula can be as follows:

The final_color is the color of the game character obtained after division and mixing, color. Xyz and color. W represent color components of the pixel points of the game character after positive film bottom stacking, and blend_color. Xyz represents color components of the second control point corresponding to the pixel points of the game character.

Further, referring to fig. 7, when a game character moves in a game scene, since the scene character includes a second scene element using the first scene element as a light source, the light of the game character is always changed along with the movement of the game character in the game scene, so that it is necessary to superimpose a color according to the position of the game character to simulate the change of brightness of the light in the game scene, specifically comprising steps S710-S730:

In step S710, determining a movement range of the third scene element in the game scene, determining a color of the movement range according to the first scene element and the second scene element included in the game scene, and generating a movement map;

In step S720, a position of the third scene in the game scene is obtained, and a color corresponding to the third scene element is determined in the mobile map according to the position;

In step S730, the color feature corresponding to the third scene element in the motion map is overlaid onto the third scene, so as to obtain the target third scene element.

Hereinafter, step S710 to step S730 will be explained and explained. In particular, since the game character moves within the texture map of the game scene, i.e., moves within a rectangular plane, a superimposed color for each position can be recorded with a rectangular map. Firstly, acquiring a moving range of a game character in a game scene, and combining a light source included in the game scene and a light beam emitted by the light source in the moving range to generate a moving map of the game character in the game scene, wherein the moving map is used for simulating the brightness change of the game scene; secondly, determining the position of the game role in the game scene, and determining the color point corresponding to the game role in the moving map according to the position of the game role in the game scene; finally, the color point feature in the mobile map is overlaid onto the game character, wherein the formula of feature overlay can be:

final_color＝float4(lerp(color.xyz,color.xyz*multiply_color.xyz,float3(multiply_color.w)),color.w)

The final_color is the color of the color point positive film in the moving map, color. Xyz and color. W represent the color components of the pixel points of the game role after positive film lamination and division mixing, and multiply _color. Xyz and multiply _color. W represent the color components of the moving map corresponding to the pixel points of the game role.

Still further, referring to fig. 8, in order to reduce the sampling number of the mobile map, the mobile map may be offline converted into a byte array, which may include steps S810-S830:

in step S810, the moving map and the third scene element are converted according to the preset width and height, so as to obtain a target moving map and a converted third scene element;

In step S820, the target movement map is converted into a byte array, the position of the converted third scene element in the game scene is determined, and a color value corresponding to the position of the converted third scene element in the game scene is acquired in the byte array;

in step S830, the color value feature is superimposed onto the converted third scene element, so as to obtain the target third scene element.

Specifically, first, before converting a movement map into a byte array, it is necessary to unify the movement map and the map of a game character, which specifically includes: the method comprises the steps of performing unified height and width conversion on texture maps of a mobile map and a game character according to preset widths and heights, wherein the preset widths and heights can be 1024 x 128 or 2048 x 256, the preset widths and heights are not limited in the example, when the preset widths and heights are 1024 x 128, the heights and the widths of the mobile map are uniformly set to 1024 x 128, and the positions of the game character in a game scene are converted to be within the 1024 x 128 range; secondly, converting the mobile map into a byte array, and storing the mobile map in the form of the array after the mobile map is loaded into a game; thirdly, determining the position of the game character in the game scene, and acquiring the pixel points of the movement map corresponding to the position of the game character in the game scene; and finally, determining a color value corresponding to the pixel point in the array according to the pixel point of the moving map, and overlapping the color value on the game role to obtain the target game role.

In step S140, the first scene element, the second scene element and the target third scene element are rendered according to the rendering groups and the rendering levels corresponding to the first scene element, the second scene element and the target third scene element, so as to obtain a target game scene.

The rendering group and the rendering hierarchy are used to determine a display order of the scene elements in the game scene, specifically, referring to fig. 9, rendering is performed according to the rendering group and the rendering hierarchy corresponding to the first scene element, the second scene element and the target third scene element, so as to obtain the target game scene, which includes step S910 and step S920:

In step S910, determining a rendering group and a rendering level to which the first scene element, the second scene element, and the target third scene element belong according to the depth values of the first scene element, the second scene element, and the target third scene element in the game scene;

In step S920, the first scene element, the second scene element, and the target third scene element are rendered according to the rendering group and the rendering hierarchy, so as to obtain the target scene element.

Hereinafter, step S910 and step S920 will be explained and explained. Specifically, first, a depth value of a scene element included in a game scene is obtained, and a rendering group of the scene element in the game scene is determined according to the depth value of the scene element, wherein the rendering group may include: the rendering groups are not particularly limited in the example, and a person skilled in the art can set different rendering groups according to the requirements of game scenes, after determining the rendering groups to which the scene elements belong, the person skilled in the art determines the rendering levels of the scene elements in the rendering groups according to the depth values of the scene elements, when the rendering groups of different scene elements are the same, the larger the values of the rendering levels are, the more upper the scene elements are rendered through the shader; when the rendering groups of the scene elements are different, the larger the rendering group is, the more the scene elements are on the upper layer when the rendering is performed through the shader; and finally, rendering the scene elements included in the game scene according to the rendering group and the rendering level of the scene elements included in the game scene to obtain the target game scene.
