According to an aspect of the embodiments of the present application, a method embodiment of a method for generating a tearing effect graph is provided.
Alternatively, in the present embodiment, the generation method of the tear effect map may be applied to a hardware environment formed by the terminal 101 and the server 103 as shown in fig. 1. As shown in fig. 1, a server 103 is connected to a terminal 101 through a network, which may be used to provide services (such as game services, application services, etc.) for the terminal or a client installed on the terminal, and a database 105 may be provided on the server or separately from the server for providing data storage services for the server 103, and the network includes but is not limited to: the terminal 101 is not limited to a PC, a mobile phone, a tablet computer, and the like.
The method for generating the tear effect map according to the embodiment of the present application may be executed by the terminal 101, and the terminal 101 executing the method for generating the tear effect map according to the embodiment of the present application may also be executed by a client installed thereon. Fig. 2 is a flowchart of a method for generating an alternative tearing effect map according to an embodiment of the present application, and as shown in fig. 2, the method may include the following steps:
step S202, the terminal obtains a first texture mapping, and the first texture mapping is used for representing the tearing effect of the first sub-area in the game background.
The client-side formed after the game application is installed on the terminal, a user can carry out game interaction through the client-side, and the tearing effect is the special effect displayed in the client-side, and can be displayed by the tearing effect if the user splits an object by using the prop knife.
In step S204, the terminal distorts the first texture map to obtain a second texture map, and processes the first texture map to obtain an edge texture map.
And step S206, the terminal obtains a tearing effect image of a target area in the game background by using the second texture map and the edge texture map, wherein the target area comprises a first subarea and a second subarea, and the first subarea and the second subarea are symmetrical subareas in the game background.
Through the steps, the terminal acquires a first texture mapping used for expressing the tearing effect of the first subarea in the game background; twisting the first texture map to obtain a second texture map, and processing the first texture map to obtain an edge texture map; the second texture mapping and the edge texture mapping are utilized to obtain the tearing effect mapping of the target area in the game background, so that the game special effect processing can be finished on the terminal without being finished through a server, and the technical problem that the game special effect expression is delayed in the related technology can be solved.
At present, almost no technical scheme for realizing the tearing effect exists, and the paper tearing effect is relatively close to the paper tearing effect, namely a mode of removing part pictures in a one-way small disturbance mode. The scheme provides a multi-directional tearing effect, such as a tearing effect from the center to two sides or from the center to the cross direction around, and the effect is shown in fig. 3. The technical solution of the present application is further detailed below with reference to the steps shown in fig. 2.
In the technical solution provided in step S202, the terminal obtains a first texture map, where the first texture map is used to represent a tearing effect of the first sub-area in the game background, and the texture map may be a texture map prepared by art in advance.
In the scheme, before the first texture map is acquired, a target area in the game background, such as an area where a target is cut by a knife of a player, which needs to be rendered to generate a tearing effect is located; the target area is divided into a first sub-area and a second sub-area which are symmetrical, the number of the first sub-area and the second sub-area is one, for example, when the target area is a rectangle, the first sub-area and the second sub-area are two small symmetrical rectangles, and when the target area is an ellipse, the first sub-area and the second sub-area are two symmetrical semi-ellipses.
The number of the second sub-regions may also be multiple, for example, when the target region is a rectangular region, and the target region is divided into a first sub-region and a second sub-region which are symmetrical, the target region may be divided into one first sub-region and three second sub-regions by using a first axis (e.g., a horizontal axis) and a second axis (e.g., a vertical axis) passing through the center of the target region, and a side of the target region perpendicular to the first axis is different from a side of the target region perpendicular to the second axis.
In the technical solution provided in step S204, the terminal performs warping processing on the first texture map to obtain a second texture map, and performs processing on the first texture map to obtain an edge texture map.
In the above solution, when the first texture map is warped to obtain the second texture map, the first texture map may be adjusted to be the second fan-shaped texture map, for example, in a game engine (e.g., a unity game engine), a V-axis of coordinates of the first texture map is taken as negative, and then the V-axis after the negative is taken is fused with a U-axis of the first texture map to obtain a fusion result; and performing enhancement processing on the fusion result by using the enhancement parameters, and performing radial range control on the enhanced fusion result by using the radial parameters to obtain a second texture mapping.
In the above scheme, when the first texture map is processed to obtain the edge texture map, the edge of the first texture map may be subjected to highlighting and dissolution disturbance processing in the game engine to obtain the edge texture map.
In the technical solution provided in step S206, the terminal obtains a tearing effect map of the target area in the game background by using the second texture map and the edge texture map.
In the above solution, obtaining the tearing effect map of the target area in the game background by using the second texture map and the edge texture map includes the following three cases:
one is that, under the condition that the second sub-region and the first sub-region are symmetrical about a first axis (such as an X axis), the coordinates of the pixel points in the second texture map on a second axis (such as a Y axis) are negated to obtain the texture map displayed on the second sub-region, and the coordinates of the pixel points in the edge texture map on the second axis are negated to obtain the texture edge displayed on the second sub-region;
secondly, under the condition that the second sub-area and the first sub-area are symmetrical about a second axis, the coordinates of the pixel points in the second texture mapping on the first axis are negated to obtain the texture mapping displayed on the second sub-area, and the coordinates of the pixel points in the edge texture mapping on the first axis are negated to obtain the texture edge displayed on the second sub-area;
and thirdly, under the condition that the second sub-area and the first sub-area are symmetrical about the center of the target area, negating the coordinates of the pixel points in the second texture mapping on the first axis and the coordinates of the pixel points in the second texture mapping on the second axis to obtain a texture mapping displayed on the second sub-area, and negating the coordinates of the pixel points in the edge texture mapping on the first axis and the coordinates of the pixel points in the second axis to obtain a texture edge displayed on the second sub-area.
In the above scheme, when the second texture map and the edge texture map are used to obtain the tearing effect map of the target area in the game background, the second texture map is output to the color node of the screen (for example, the second texture map is processed by using the phase parameter, the gradual change smoothing parameter and the bright part intensity parameter, and the processed second texture map is output to the color node of the screen), so as to be fused with the edge texture map, and obtain the tearing effect map of the target area in the game background.
As an alternative example, the following detailed description will further describe the technical solution of the present application by taking the example shown in fig. 4 in conjunction with the specific implementation manner:
step S402, determining the background position according to the current camera, setting a rectangle with the size of the tearing space, and confirming the central point.
Step S404, a rectangular surface is created from the top left corner of the rectangle to the center point (or the surface can be created in other directions), and the surface is mirror-copied three times in three directions, i.e. right, down, and right, and four surfaces also form a large rectangle with the center point as the center. Then, based on the upper left surface, the shader is manufactured by warping from the center point to the upper left and using the warping change of the process as a parameter.
In step S406, a semicircular texture (denoted as texture 1) is distorted and deformed, and finally becomes a controllable segment sector from the lower right to the upper left.
Texture Coordinates are model Texture information nodes, and the Texture on a model is mapped into an adjustable sector, which is the meaning of the nodes (i.e. Clamp, One Minus and the like nodes, which are nodes provided by the Unity engine).
The UV of texture coordinates is first processed separately, taking the V-axis negative at the One Minus node and Clamp node, and shifting the center point from top right to bottom right. The processed UV axis is fused at a multiplex node (the fusion uses an algorithm of the multiplex node, the core is to Multiply two input data), a parameter is added and Power calculation is performed with the fused result (the exp Power input by the node generally indicates strengthening and adjusting a black-and-white edge, the smaller the value is, the whiter the whole texture is, the larger the value is, the blacker the whole texture is), the intensity is increased, a parameter is added to indicate the radial range, the value can be reduced to a lower value, and the structural diagram of the scheme in Unity is shown in fig. 4.
The scheme can adjust the smoothness and the strength of the edge of the sector gradual change, the sector can be in black-white gradual change, the brightness is from white to black (the white is more bright), and the texture display alpha transparent channel can be adjusted through the sector, so that the scheme needs to form the cross-shaped tear, and the texture can be changed into an adjustable transparent 1/4 circle.
Step S408 is to take the output of step S406 as the input of the transparent channel, and take the two parameters (i.e. the two float values of parameter a and parameter B) as parameters to perform linear difference calculation, as shown in fig. 5.
Since the purpose of the solution is to complete the cross tearing effect, a texture is changed into an adjustable transparent 1/4 circle, so that the same texture can be copied into four parts, and thus a cross tearing effect can be pieced together, step S406 is to make one layer of texture fade from top right to top left in a fan-shaped manner by adjusting the transparency, which is equivalent to making the second layer of texture appear in a similar manner.
The two floats may be derived from two control nodes added to Unity, such as one with a value of 0 and one with a value of 1, and are used to control the alpha (i.e., α channel) in step S406, and the linear difference is implemented by the Lerp node, which has three values, respectively A, B, alpha, so as to control the intensity of the alpha.
And processing the result and the Screen coordinate through an Add node (namely, an addition node which can complete a set of operations of adding the position information to the change of the alpha channel and assigning a value to the UV information of the Screen, namely, modifying and deforming the alpha channel to control the texture change of the model), inputting the UV information into a color node of a Screen as UV, and outputting RGBA in the node for processing. The transparent animation of the whole alpha is controlled by four parameters: gradual smoothness smooth, bright intensity, and overall phase values a and B.
In step S406 and step S408, using several parameters, the radial fan deformation adjusted by black-and-white gradual change is mapped onto the screen parameters of the face pointed by the camera (i.e. the face with the shader, and the image of the face is the image taken by the camera, like the screenshot, so when the distortion deformation is made, the change is the image pointed by the camera when the deformation occurs, which can ensure that the effect is still normal when the angle of the camera is changed).
In step S410, the image is distorted and the edge is disturbed, strengthened and dissolved. As shown in fig. 6 and 7 (fig. 6 and 7 are rotated to see the content in the figure because of the large content), two different gray textures are first used to move at the same speed and direction, the two textures are overlapped, and are fused with the texture (texture 1) coordinates, so that a rapid edge perturbation is completed, and the structure in unity is shown in fig. 6.
And processing the obtained disturbing image of the texture 1, and only outputting the effect of one edge. Specifically, a certain channel value of the disturbing image is output twice, one of the channel values is superposed with a width parameter, because only two colors, namely black and white, can be subtracted, and the channel with the width only keeps the width part, so that the efficiency is higher. The edge is fused with a color parameter to obtain the final output of step S410.
And S512, overlapping the results obtained in the step S508 and the step S510 to form a final shader, and assigning the final shader to other three surfaces, wherein the surfaces are in mirror image relationship, so that the distortion animation is deformed towards four different directions, and the tearing and dissolving effect towards four directions simultaneously is completed.
