[0050] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are 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 ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0052] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0053] In the description of the present application, it should be noted that the terms "first", "second", etc., if used, are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0054] It should be noted that, in the absence of conflict, the features in the embodiments of the present application may be combined with each other.

[0055] Figure 1 The flowchart of the method for realizing a display screen with a flashing effect provided by an embodiment of the present application is shown. The method for realizing a display screen provided by the present application can be applied to a computer device and realized by the computer device. It should be understood that in other embodiments, the order of some steps in the method for realizing a display screen described in this embodiment can be interchanged according to actual needs, or some steps can be omitted or deleted. The detailed steps of the method for realizing a display screen are described as follows.

[0056] Step S110, obtaining a scene object map to be reflected and a star map, and obtaining multiple frames of reference images.

[0057] Step S120: superimpose the scene object map and the star map onto each frame of the reference picture.

[0058] Step S130, transforming the brightness values ​​of the scene object map and the star map in the reference picture of each frame.

[0059] Step S140, rendering and displaying the multiple frames of display pictures obtained after the transformation process.

[0060] In the prior art, when implementing plane reflection, the template test is usually used to implement mirror reflection. The implementation method is usually to draw the scene objects once, then draw the mirror into the template cache and turn on the template test, clear the depth cache and turn on blending, and finally render the object to be reflected. Alternatively, in another existing implementation method, it can be implemented by rendering to a texture. The implementation method is usually to first draw the objects in the scene once, save the drawing results to a texture, perturb the vertex data in the vertex shader, and use Fresnel reflection in the pixel shader to control transparency.

[0061] Among the above-mentioned prior arts, the first method is the reflection of a plane mirror. Because it is directly rendered, the final rendered image is similar to a mirror and cannot be disturbed. The second water surface reflection method solves the problem of vertex data disturbance and uses Fresnel to solve the problem of water surface transparency. However, this method still makes it difficult to achieve the effect of a galaxy flashing based on the water surface.

[0062] In this embodiment, a three-dimensional game scene is used as an example for explanation. When a water surface effect is involved in the game scene, on the one hand, a ripple effect of the water surface needs to be designed, and on the other hand, a galaxy flashing effect based on the water surface is desired. Therefore, this embodiment provides a display screen implementation method for implementation.

[0063] In this embodiment, a scene object map to be reflected is prepared in advance, and the scene object map can be set according to the scene objects around the water surface in the scene, for example, it can include trees, mountains, vegetation, buildings, objects, etc. The scene object map needs to be superimposed on the water surface to simulate the reflection effect of the water surface on the surrounding scene.

[0064] The star map may be a block or dot map with a certain glossy color, which is used to simulate the flashing effect of the water surface in the subsequent simulation. In addition, multiple frames of reference images may be prepared in advance, wherein the reference image is the water surface image in the game scene. The pre-prepared reference image may include vertex data of the water surface, including the position information of the XYZ coordinates of the vertices, and the UVW sampling coordinate information of the vertices.

[0065] In this embodiment, the prepared star map and scene object map need to be eventually superimposed on the reference picture, and the flashing effect is mainly achieved by changing the brightness values ​​of the scene object map and the star map between different frames. Therefore, when multiple frames are rendered and displayed and played continuously, the brightness values ​​of the scene object map and the star map are constantly changing, so the flashing effect of the water surface can be simulated.

[0066] In this embodiment, considering that the base screen in a general game scene, for example, the land on the water surface is generally large, for example, the land may reach an area of ​​512 meters * 512 meters. Therefore, if the star map is directly superimposed on the base screen, if the accuracy of the star map is not high enough, it may cause the star map to be blurred.

[0067] In order to avoid the above problems, as a possible implementation method, the problem can be solved by improving the accuracy of the star map, for example, the accuracy of the star map can be improved to 1024*1024. As another possible implementation method, the range of the reference screen to which the star map is attached can be reduced, for example, the reference screen area can be adjusted by adjusting the vertex information of the reference screen, for example, the reference screen area can be adjusted to within the range of 64 meters*64 meters. As another implementation method, the problem can also be solved by reducing the pixels in the star map. For example, if dozens of pixels are required to express a star map, it can be changed to using a few pixels to express a star map.

[0068] In this embodiment, in order to simulate the ripple effect on the water surface, please refer to Figure 2 , the reference picture can be processed in the following ways:

[0069] Step S121, obtaining vertex data of the reference picture of each frame.

[0070] Step S122, perturbing the vertex data in a vertex shader.

[0071] Step S123, superimposing the scene object map and the star map onto each frame of the reference picture after disturbance.

[0072] In this embodiment, the UV data in the vertex data of the reference picture can be disturbed in the vertex shader, so that the reference picture presents an undulating effect, that is, simulating the effect of ripples on the water surface. On this basis, the scene object map and the star map are superimposed on the disturbed reference picture.

[0073] In this embodiment, the star map may include multiple images, so that the brightness can be changed not only between different picture frames, but also between different star maps, so as to better simulate the random flashing effect.

[0074] See also Figure 3 , when transforming the brightness values ​​of the scene object map and the star map, the above can be achieved in the following ways:

[0075] Step S131, setting different brightness values ​​for the scene object map in the reference picture of each frame.

[0076] Step S132, setting different overall brightness values ​​for the multiple star maps in each frame of the reference picture, and setting different individual brightness values ​​for each star map in each frame of the reference picture.

[0077] In this embodiment, a global variable may be used to control the brightness information. For example, the type of the global variable may be float4 type, wherein the global variable may include an x ​​variable, a y variable, a z variable, and a w variable.

[0078] In this embodiment, different brightness values ​​can be set for the scene object maps in each frame of the reference picture, and the brightness values ​​can be stored in the z variable in the global variable. In addition, different overall brightness values ​​can be set for multiple star maps in each frame of the reference picture, and the overall brightness values ​​can be stored in the x variable in the global variable.

[0079] In this embodiment, when setting the overall brightness value of the star map for each frame of the reference picture, a brightness value range may be pre-set, starting from the minimum brightness value in the brightness value range, and sequentially and cyclically setting the overall brightness value of the star map for each frame of the reference picture in the multiple frames of the reference picture within the brightness value range. In this way, the overall brightness value of the star map in the multiple frames of the reference picture will show a regular brightness change. Alternatively, in another embodiment, it is also possible to start from the maximum brightness value in the above-mentioned brightness value range, and sequentially and cyclically set the overall brightness value of the star map for each frame of the reference picture in the multiple frames of the reference picture within the brightness value range.

[0080] In addition, in this embodiment, different individual brightness values ​​are set for each star map in each reference picture. In the final picture, the brightness of the star map is determined by the overall brightness value of the star map in each frame and the individual brightness value of each star map.

[0081] See also Figure 4 In this embodiment, for each reference picture, different individual brightness values ​​are set for each star map in the following manner:

[0082] Step S1321 : for each frame of the reference picture, an initial individual brightness value is set for the reference picture.

[0083] Step S1322: Expand based on the initial individual brightness value to obtain a plurality of individual brightness values ​​corresponding to each star map.

[0084] In this embodiment, the number of star maps in each frame of the reference picture can be set according to the needs, for example, it can include three star maps, four star maps, etc. When setting the brightness value for each frame of the reference picture, an overall brightness value can be set for all the star maps in each frame of the reference picture, and an initial individual brightness value can be set. The initial individual brightness value can be the same as the overall brightness value, or the initial individual brightness value can be different from the overall brightness value, and there is no specific limitation.

[0085] On the basis of the set initial individual brightness value, the individual brightness value can be expanded according to the number of star maps. For example, if the number of star maps is three, three individual brightness values ​​can be expanded based on the initial individual brightness value. The three individual brightness values ​​can be different in size, partially the same, or the same. The specific embodiment is not limited. During implementation, in order to simulate a random flashing effect, the values ​​of the multiple individual brightness values ​​obtained by expansion can be different, so that a random flashing effect can be achieved.

[0086] In this embodiment, the generation of the initial individual brightness value of the star map can be completed in the CPU of the computer device. After the initial individual brightness value is generated, the GPU can expand the initial individual brightness value to obtain multiple individual brightness values ​​corresponding to multiple star maps. In this way, the initial individual brightness value only needs to be calculated once in the CPU, avoiding the problem of increasing the amount of calculation caused by the influence of the number of vertices and the final output image resolution when performing information calculation in the GPU.

[0087] In this embodiment, after the brightness value conversion process is implemented, in order to realize the display of the final display picture, the display picture to be displayed needs to be rendered. To realize the rendering process, the pixel value of each pixel point needs to be determined to realize the display.

[0088] Optionally, see Figure 5 When rendering and displaying the multi-frame display images obtained after the transformation, it can be achieved in the following ways:

[0089] Step S141 , for each pixel point in each frame of the display picture after the transformation processing, sample and obtain the pixel values ​​of the pixel points of the star map and the pixel points of the scene object map in the display picture.

[0090] Step S142, determining the pixel values ​​of the pixels in the display image according to the pixel values ​​of the pixel points of the star map and the pixel values ​​of the pixel points of the scene object map, and performing rendering and display.

[0091] In this embodiment, the rendering display of the display screen can be realized based on the pixel shader, and the display effect of each pixel point in the display screen is determined by the pixel information of the sampled pixel points in the scene object map and the star map.

[0092] Assuming that there are three star maps, the pixel values ​​of the sampled star maps can be recorded as StarCol1, StarCol2, and StarCol3, respectively, and the pixel value of the sampled pixel point of the scene object map can be recorded as ReflCol. The above global variable can be recorded as CtrlF4. For the pixel point on the display screen to be processed, the pixel value of the pixel point can be determined according to the pixel values ​​StarCol1, StarCol2, and StarCol3 of the pixel point of the star map and the pixel value ReflCol of the pixel point of the scene object map.

[0093] Optionally, see Figure 6 , the pixel value of the pixel in the display can be determined by:

[0094] Step S1421, obtaining pixel conversion values ​​of each of the star maps according to the pixel values ​​of the pixel points sampled from each of the star maps and the corresponding brightness information.

[0095] Step S1422: Obtain pixel conversion values ​​of the scene object map according to pixel values ​​of the pixel points of the scene object map and corresponding brightness information.

[0096] Step S1423, determining the pixel value of the pixel point in the display image based on the pixel conversion value of each of the star maps and the pixel conversion value of the scene object map.

[0097] In this embodiment, each of the star maps has transparency information. For each star map, the pixel value under transparency can be obtained according to the pixel value obtained by sampling the star map and the corresponding transparency. For example, the pseudo code for implementation can be as follows, where a represents transparency:

[0098] StarCol1*=StarCol1.a;

[0099] StarCol2*=StarCol2.a;

[0100] StarCol3*=StarCol3.a;

[0101] On this basis, according to the pixel values ​​under the above transparency and the individual brightness values ​​and overall brightness values ​​of the star map, the pixel conversion value of the star map is obtained. Among them, the intermediate value is obtained based on the pixel value and the individual brightness value through the pseudo code shown below:

[0102] StarCol1*=CtrlF4.y;

[0103] StarCol2*=(2.0f-CtrlF4.y);

[0104] StarCol3*=CtrlF4.y*1.5f;

[0105] Among them, y represents the individual brightness value of the star map, and f indicates that the variable type is float type.

[0106] On the basis of the above, combined with the overall brightness value of the star map in the display screen, the pixel conversion value of the star map is obtained through the following pseudo code:

[0107] StarCol1*CtrlF4.x;

[0108] StarCol2*CtrlF4.x;

[0109] StarCol3*CtrlF4.x;

[0110] After obtaining the pixel conversion value of the star map in the above manner, the pixel value OutCol of the pixel point in the display screen can be obtained by combining the pixel conversion value of the star map with the pixel conversion value of the scene object map in the following manner:

[0111] OutCol=StarCol1*CtrlF4.x+StarCol2*CtrlF4.x+StarCol3*CtrlF4.x+ReflCol*CtrlF4.z

[0112] Finally, the display screen can be rendered based on the obtained pixel values ​​of the pixels.

[0113] In this embodiment, the flashing effect is achieved by transforming the brightness values ​​of the star map and the scene object map. When setting the brightness, the brightness value can be set once in the CPU. On this basis, the brightness value can be expanded in the GPU based on the set brightness value to obtain the individual brightness value of each star map. In the pixel shader, the pixel values ​​of the pixel points sampled from different maps are combined for mixing processing to obtain the pixel values ​​of the pixel points of the final image to be displayed, thereby achieving rendering display.
