[0013] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in connection with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. The components of the embodiments of the present application described and shown in the accompanying drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0014] In some virtual scenes, such as game scenes, transition effects are usually used to smoothly connect scenes. Currently, animation transitions are usually simulated in the form of hand-drawn sequence frames, or transition videos are made to be applied to transition transitions in video format, or conventional black screen switching effects are used as transition transitions.

[0015] However, the hand-drawing method greatly increases the production difficulty and period, and the landing effect needs to consume a large number of sequence frame animations to realize the smooth transition, and the use of transition video needs to switch between the content generation tool and the game engine, which reduces the production efficiency, and in order to ensure the clarity, the transition video also occupies a large amount of memory consumption, and the video format also needs to be compressed and transcoded, and different encoding formats correspond to different devices, which also has certain compatibility problems. In summary, the hand-drawing method and the transition video method have low generation efficiency of dynamic effects, in addition, the transition effect of the black screen switching effect is single and the visual feeling is not good.

[0016] Based on this, the application generates target transition dynamic effects by map processing and animation rendering. The map has universality and extensibility, that is, it does not depend on the specific system of the game engine and the digital asset generation tool (that is, the content generation tool), and can perform effect performance in multiple production environments. In addition, a large number of sequence frame animations and large content video formats are converted into maps with stronger compatibility and smaller memory occupation, which improves the generation efficiency of transition dynamic effects and game performance.

[0017] The transition dynamic effect generation method in one of the embodiments of the application can run on a local terminal device or a server. When the transition dynamic effect generation method runs on the server, the method can be implemented and executed based on a cloud interaction system, wherein the cloud interaction system includes a server and a client device.

[0018] In an optional embodiment, various cloud applications can be run under the cloud interaction system, for example: cloud games. Taking cloud games as an example, cloud games refer to a game mode based on cloud computing. In the running mode of cloud games, the running body of the game program and the presentation body of the game picture are separated, and the storage and running of the transition dynamic effect generation method are completed on the cloud game server. The client device is used for data reception, sending and game picture presentation. For example, the client device can be a display device close to the user side with data transmission function, such as a mobile terminal, a television, a computer, a palm computer, etc.; but the information processing is performed by the cloud game server in the cloud. When playing the game, the player operates the client device to send operation instructions to the cloud game server, the cloud game server runs the game according to the operation instructions, encodes and compresses the game picture data, returns the data to the client device through the network, and finally decodes and outputs the game picture through the client device.

[0019] In an optional embodiment, taking a game as an example, the local terminal device stores a game program and is configured to present a game picture. The local terminal device is configured to interact with a player through a graphical user interface, i.e., a conventional game program is downloaded and installed through an electronic device and is run. The local terminal device can provide the graphical user interface to the player in various ways, for example, the graphical user interface can be rendered and displayed on a display screen of the terminal, or the graphical user interface can be provided to the player through holographic projection. For example, the local terminal device can include a display screen configured to present the graphical user interface including the game picture, and a processor configured to run the game, generate the graphical user interface, and control display of the graphical user interface on the display screen.

[0020] In a possible embodiment, the embodiment of the present application provides a transition effect generation method. The graphical user interface is provided through a terminal device. The terminal device can be the local terminal device mentioned above or the client device in the cloud interaction system mentioned above.

[0021] Figure 1 Flowchart of the transition effect generation method provided by the embodiment of the present application Figure One The execution subject of the embodiment can be an electronic device, such as a computer.

[0022] As shown in Figure 1 The method can include the following steps. S101, obtaining a transition dissolve map corresponding to a to-be-processed sequence animation.

[0023] The transition dissolve map is a grayscale map having motion information of a moving object in the to-be-processed sequence animation.

[0024] The to-be-processed sequence animation includes a plurality of image frames, for example, a plurality of continuous image frames in a video. The moving object is included in each image frame, and the motion information of the moving object in different image frames can be different. The motion information refers to the position and orientation of the moving object. That is, the transition dissolve map is used to represent the motion trajectory of the moving object in the to-be-processed sequence animation.

[0025] S102, performing grayscale adjustment on the transition dissolve map according to a preset control map sequence to obtain a transparency map sequence.

[0026] Each control map in the preset control map sequence includes time-varying control parameters in sequence. One control map includes one control parameter, different control maps include different control parameters, and the control parameters included in different control maps are time-varying, for example, the control parameter included in the first control map is 0.1, the control parameter included in the second control map is 0.2, the control parameter included in the third control map is 0.3, and other control maps are sequentially similar.

[0027] That is, according to each control map in the preset control map sequence with the time sequence relationship, the grayscale of the transition dissolve map is adjusted to obtain a transparency map sequence, wherein each transparency map in the transparency map sequence corresponds to each control map in the preset control map sequence respectively, and each transparency map in the transparency map sequence has a corresponding time sequence relationship.

[0028] It should be noted that the control parameters included in the control map can be understood as the grayscale values of each pixel point in the control map (the grayscale values of all pixel points in the control map are the same), and the pixel points in the control map, the pixel points in the transition dissolve map, and the pixel points in the transparency map are one-to-one corresponding. The grayscale adjustment of the transition dissolve map can be understood as adjusting the grayscale values of the corresponding pixel points in the transition dissolve map based on the grayscale values of the pixel points in the control map, such as subtracting the grayscale value of the corresponding pixel point in the control map from the grayscale value of each pixel point in the transition dissolve map to obtain the grayscale value of the corresponding pixel point in the transparency map.

[0029] In some embodiments, a material shader of the particle is written to be able to sample the control map and adjust the grayscale of the transition dissolve map to realize the particle special effect.

[0030] S103, according to the transparency map sequence, the preset transition image is animated and rendered to generate a target transition dynamic effect.

[0031] The preset transition image is a scene image used for transition, the transparency map sequence is stored to the transparency (alpha, A) channel of the preset transition image as the A channel transparency map, and the A channel transparency map, the Red (R) channel map of the R channel of the preset transition image, the Green (G) channel map of the G channel, and the Blue (B) channel map of the B channel are animated and rendered, that is, each transparency map in the transparency map sequence is animated and rendered to the preset transition image to generate a target transition dynamic effect, wherein the target transition dynamic effect includes: a plurality of transition image frames in sequence based on the preset transition image, to indicate the motion trajectory of the moving object in the preset transition image, to realize the smooth motion of the moving object in the preset transition image, that is, the transition animation from one transition image frame to another transition image frame.

[0032] In the transition effect generation method provided in the embodiment, the transition dissolve graph is gray-scale adjusted according to the preset control map sequence to obtain a transparency map sequence, so that the transparency map sequence is more random and natural, and then the preset transition image is animated rendered according to the transparency map sequence to generate a target transition effect, so that the smooth motion of the moving object in the preset transition image is realized on the basis of the preset transition image, and the transition effect of the target transition effect is more random and natural. In addition, the target transition effect is generated by animation rendering through map processing, the map has universality and extensibility, that is, it is independent of the specific system of the game engine and the digital asset generation tool (that is, the content generation tool), and can perform effect performance in multiple production environments. Moreover, a large number of sequence frame animations and large content video formats are converted into maps with stronger compatibility and smaller memory occupation, thereby improving the transition effect generation efficiency and game performance.

[0033] Figure 2 Flowchart of transition effect generation method provided in the embodiment Figure Two As shown in Figure 2 In an optional implementation, the step S101 of obtaining the transition dissolve graph corresponding to the to-be-processed sequence animation can include the following steps. S201, single-channel conversion is performed on a plurality of image frames in the to-be-processed sequence animation to obtain single-channel gray-scale images of the plurality of image frames.

[0034] The to-be-processed sequence animation includes a plurality of image frames, and a single-channel channel map of the plurality of image frames is extracted to perform single-channel conversion on the plurality of image frames. The extracted single-channel channel map is used as a single-channel gray-scale image of each image frame.

[0035] It should be noted that the extracted single channel can be any one of the R channel, the G channel and the B channel.

[0036] S202, the single-channel gray-scale images of the plurality of image frames are superimposed to obtain a transition dissolve graph.

[0037] The different time frames are superimposed together to convert the to-be-processed sequence animation into a single transition dissolve graph with different gray-scale information, so that the transition dissolve graph reflects the motion trajectory of the moving object, and realizes effects such as ghosting, motion blur, light and shadow following. The transition dissolve graph is also a time-domain phase information graph.

[0038] That is, the dynamic change of each image frame in the to-be-processed sequence animation is mapped to the R channel of a picture, and the animation transition of each frame is calculated through different gray-scale information.

[0039] Figure 3 A schematic diagram of the single-channel gray-scale image provided in the embodiment of the application is shown in Figure 4A schematic diagram of the transition dissolve diagram provided by the embodiments of the present application is shown in Figure 3 As shown in Figure 4 , 40 single-channel grayscale images of 40 image frames are superimposed to obtain the transition dissolve diagram.

[0040] In some embodiments, a Digital Content Creation (DCC) tool is used to convert multiple image frames in the sequence animation to be processed into single-channel grayscale images, and an image superimposition tool, such as CC WideTime, is used to superimpose the single-channel grayscale images of multiple image frames to generate a transition dissolve diagram, and the grayscale range of the transition dissolve diagram is 0-255.

[0041] Figure 5 A flowchart of the transition effect generation method provided by the embodiments of the present application is shown in Figure Three As shown in Figure 5 , in an optional implementation, before the step S201 of converting multiple image frames in the sequence animation to be processed into single-channel grayscale images, the method can further include: S301, determining a starting image frame and a terminal image frame from the sequence animation to be processed according to an input image frame selection operation for the sequence animation to be processed.

[0042] S302, determining multiple image frames from the sequence animation to be processed according to the starting image frame and the terminal image frame.

[0043] An image frame selection interface is provided, and the starting image frame and the terminal image frame are determined from the sequence animation to be processed through the image frame selection operation input by the interface, wherein the image frame selection operation is used to select the starting image frame and the terminal image frame. Then the starting image frame, the terminal image frame, and the image frames between the starting image frame and the terminal image frame in the sequence animation to be processed are taken as the multiple image frames.

[0044] Figure 6 A schematic diagram of the image frame selection interface provided by the embodiments of the present application is shown in Figure 6 As shown in

[0045] In the transition effect generation method provided by the embodiments, the starting image frame and the terminal image frame are manually set to determine the multiple image frames, which is more flexible in operation.

[0046] Figure 7 A flowchart illustrating the transition animation generation method provided in this application embodiment. Figure Four ,like Figure 7 As shown, in an optional embodiment, step S102 above, which involves adjusting the grayscale of the transition dissolve map according to a preset control map sequence to obtain a transparency map sequence, may include: S401. Obtain the control texture sequence in at least one dimension.

[0047] At least one dimension is a float4 variable defined by Dissolve control (Dissolve_controll), namely, degree of dissolution (x), edge feathering (y), and edge width (z). Degree of dissolution refers to the process of an image gradually transitioning from one state (such as complete) to another (such as complete transparency or disappearance). Edge feathering refers to creating a smooth gradient effect at the image edges, making the edges look more natural and reducing harsh boundaries. Feathering effects are usually achieved through blurring or gradation. Edge width defines the range of the feathering effect; the larger the width, the smoother the transition.

[0048] Each control map in the control map sequence for each dimension includes, in turn, the control parameters that change over time for each dimension.

[0049] Each control map in each dimension includes a control parameter for that dimension. Different control maps include different control parameters for each dimension, and the control parameters included in different control maps change over time.

[0050] It should be noted that the control parameters of the control map in each dimension can be understood as the grayscale values ​​of each pixel in that control map.

[0051] S402. Based on the control map sequence in at least one dimension, adjust the grayscale of the transition dissolution map to obtain the transparency map sequence.

[0052] Based on each control map in the control map sequence under each dimension, the grayscale of the transition dissolve map is adjusted to make the transition of each transparency map in the resulting transparency map sequence smoother in at least one dimension.

[0053] Figure 8 A flowchart illustrating the transition animation generation method provided in this application embodiment. Figure Five ,like Figure 8 As shown, in an optional implementation, the control map sequence in at least one dimension includes: a control map sequence in a first dimension, wherein each control map in the control map sequence in the first dimension includes: a dissolution degree parameter that changes over time in the first dimension.

[0054] The first dimension can be a dissolution degree, and each control map in the control map sequence in the first dimension includes a time-varying dissolution degree parameter in the first dimension in sequence, wherein the time-varying control parameter in the first dimension includes the time-varying dissolution degree parameter in the first dimension.

[0055] In the step S402, the transition dissolution map is gray-scale adjusted according to the control map sequence in the at least one dimension to obtain a transparency map sequence, and the transparency map sequence can include: S501, adjusting the dissolution degree of the transition dissolution map according to the control map sequence in the first dimension to obtain a first dissolution map sequence.

[0056] The control map sequence in the first dimension includes a plurality of control maps, the first dissolution map sequence includes a plurality of first dissolution maps, and the control map and the first dissolution Figure One correspond, and the pixel points in the control map, the pixel points in the transition dissolution map, and the pixel points in the first dissolution map correspond one by one.

[0057] It should be noted that the dissolution degree parameter of the control map in the first dimension can be understood as the gray value of each pixel point in the control map.

[0058] In some embodiments, the gray value of each pixel point in the transition dissolution map is subtracted from the gray value of the pixel point in each control map in the control map sequence in the first dimension to adjust the dissolution degree of the transition dissolution map to obtain the gray value of the pixel point in the first dissolution map.

[0059] For example, A is the gray value of the pixel point in the transition dissolution map, B.x is the gray value of the pixel point in the control map in the first dimension, and the gray value of the pixel point in the first dissolution map is represented as saturate(A-B.x). Wherein, saturate is a normalization function for normalizing the value in [0, 1].

[0060] In other embodiments, for each control map in the control map in the first dimension, a target pixel point is determined from each pixel point in the transition dissolution map according to the gray value of each pixel point in the transition dissolution map and the gray value of the pixel point in the control map, wherein the gray value of the target pixel point is less than the gray value of the pixel point in the control map, and the gray value of the target pixel point in the transition dissolution map is set to 0 to adjust the dissolution degree of the transition dissolution map, and the gray values of the remaining pixel points remain unchanged, thereby generating the first dissolution map corresponding to each control map, and further obtaining the first dissolution map sequence.

[0061] In some embodiments, a material shader of a particle is written to enable sampling of the control map and adjusting the dissolution degree of the transition dissolution map to realize the dissolution special effect.

[0062] S502, obtaining a transparency map sequence according to the first dissolve map sequence.

[0063] In some embodiments, the first dissolve map sequence is taken as the transparency map sequence.

[0064] In the transition effect generation method provided in the embodiment, the dissolve degree of the transition dissolve map is adjusted according to the control map sequence in the first dimension to obtain the first dissolve map sequence, and then the transparency map sequence is generated, so that the dissolve degree of each transparency map in the transparency map sequence is more smoothly transitioned.

[0065] Figure 9 Flowchart of the transition effect generation method provided in the embodiment Figure Six As shown in the figure, in an optional embodiment, the control map sequence in at least one dimension includes: a control map sequence in a second dimension, and each control map in the control map sequence in the second dimension includes: a dissolve edge feathering parameter that changes over time in the second dimension. Figure 9

[0066] The second dimension can be edge feathering, and each control map in the control map sequence in the second dimension includes: a dissolve edge feathering parameter that changes over time in the second dimension, wherein the control parameter that changes over time in the second dimension includes the dissolve edge feathering parameter that changes over time in the second dimension.

[0067] The step S502 of obtaining the transparency map sequence according to the first dissolve map sequence can include: S601, adjusting the edge feathering degree of the first dissolve map sequence according to the control map sequence in the second dimension to obtain a second dissolve map sequence.

[0068] The control map sequence in the second dimension includes a plurality of control maps, the second dissolve map sequence includes a plurality of second dissolve maps, and the control maps and the second dissolve maps are one-to-one corresponding. Figure One The pixel points in the control maps, the pixel points in the first dissolve maps, and the pixel points in the second dissolve maps are one-to-one corresponding.

[0069] It should be noted that the dissolve edge feathering parameter of the control map in the second dimension can be understood as the gray value of each pixel point in the control map.

[0070] According to the control map sequence in the second dimension, the edge feathering degree of the first dissolve map in the first dissolve map sequence is adjusted to make the edge more natural and reduce the harsh boundary, thereby obtaining the second dissolve map sequence.

[0071] ​For example, A is the gray value of a pixel in the transition dissolution map, B.x is the gray value of a pixel in the control map in the first dimension, B.y is the gray value of a pixel in the control map in the second dimension, the gray value of a pixel in the first dissolution map is expressed as: saturate(A-B.x), and the gray value of a pixel in the second dissolution map is expressed as: saturate(A-B.x / (A*B.y)).

[0072] Therefore, when the value of B.y is closer to 0, the gray value of a pixel in the first dissolution map tends to 1, resulting in hard edges, and vice versa, the greater B.y is, the gray value of a pixel in the first dissolution map tends to 0, which tends to be transparent in image representation and produces the effect of softening the edges.

[0073] S602, obtaining a transparency map sequence according to the second dissolution map sequence.

[0074] In some embodiments, the second dissolution map sequence is taken as the transparency map sequence.

[0075] In the transition effect generation method provided in the embodiment, on the basis of the first dissolution map sequence, the edge feathering degree of the first dissolution map in the first dissolution map sequence is further adjusted according to the control map sequence in the second dimension, so that the edge is more natural, the hard boundary is reduced, and the subsequent transition effect is more natural. Figure 10 The flowchart of the transition effect generation method provided in the embodiment of the application Figure Seven As shown in the figure, in an optional implementation, the control map sequence in at least one dimension includes: a control map sequence in a third dimension, and each control map in the control map sequence in the third dimension includes a dissolution edge width parameter in the third dimension that changes over time. Figure 10 The third dimension can be an edge width, and each control map in the control map in the third dimension includes a dissolution edge width parameter in the third dimension that changes over time, wherein the control parameter in the third dimension that changes over time includes the dissolution edge width parameter in the third dimension that changes over time.

[0076] The above step S602 of obtaining a transparency map sequence according to the second dissolution map sequence can include:

[0077] S701, adjusting the dissolution edge width of the second dissolution map sequence according to the control map sequence in the third dimension to obtain a third dissolution map sequence. The third dissolution map sequence includes a plurality of third dissolution maps, and the control map and the third dissolution map in the third dimension are one-to-one corresponding.

[0078] Figure One ​There is a one-to-one correspondence, and the pixels in the control texture, the pixels in the first dissolved image, the pixels in the second dissolved image, and the pixels in the third dissolved image are in a one-to-one correspondence.

[0079] It should be noted that the melt edge width parameter of the control map in the third dimension can be understood as the grayscale value of each pixel in the control map.

[0080] Based on the control map sequence in the third dimension, the edge width of the second dissolution map in the second dissolution map sequence is adjusted to make the edge wider and the feathering effect range larger, thus obtaining the third dissolution map sequence.

[0081] For example, if A is the grayscale value of a pixel in the transition dissolution map, Bx is the grayscale value of a pixel in the control map in the first dimension, By is the grayscale value of a pixel in the control map in the second dimension, and Bz is the grayscale value of a pixel in the control map in the third dimension, and the grayscale value of a pixel in the second dissolution map is represented as: saturate(A - Bx / (A * By)), then the grayscale value of a pixel in the third dissolution map is represented as: saturate(A - (B.x+Bz) / (A * (B.y+Bz))).

[0082] S702. Obtain the transparency map sequence based on the third dissolution map sequence.

[0083] In some embodiments, the third dissolve map sequence is used as a transparency map sequence.

[0084] In the transition animation generation method provided in this embodiment, based on the second dissolution map sequence, the edge width of the second dissolution map in the second dissolution map sequence is further adjusted according to the control map sequence in the third dimension, so that the range of edge feathering effect is larger and the subsequent transition animation is more natural. Figure 11 A flowchart illustrating the transition animation generation method provided in this application embodiment. Figure Eight ,like Figure 11 As shown, in an optional implementation, the method may further include: S801, Obtain the grayscale value of the edge pixels in the transparency map sequence.

[0085] The transparency map sequence includes multiple transparency maps. The grayscale value of the edge pixels in each transparency map is obtained. The edge pixels are the image edges of each transparency map. The specific range of the image edges can be determined according to the actual situation. This embodiment does not make any special limitation on this.

[0086] S802. Obtain the color of the edge pixel based on the grayscale value of the edge pixel and the preset original color.

[0087] The preset original color is an original color of the material corresponding to the edge pixel point. The preset original color can be, for example, an RGB color. The color of the edge pixel point is obtained by multiplying the grayscale value of the edge pixel point and the preset original color.

[0088] The mapping relationship between the pixel points in the image and the surface material of the 3D model plays a key role in rendering, texture mapping, material editing, and visual effects.

[0089] S803, the color of the edge pixel point is re-determined according to the color of the edge pixel point, the preset original color, and the preset color mixing parameter.

[0090] The preset color mixing parameter is B.w, which is used to smoothly mix the colors of the two parts at the edge of the image.

[0091] The lerp (preset original color, dissolved edge color, calculation result) is used to calculate the dissolved color result F1.

[0092] The lerp (preset original color, dissolved edge color, step (0.01, calculation result)) is used to calculate the dissolved result F2.

[0093] The lerp function is used to smoothly transition between two colors. By adjusting the interpolation parameter calculation result, a smooth dissolution effect from the original color of the material to the dissolved edge color can be achieved. The step function is used to map the input value to 0 or 1 according to a threshold. The calculation result is the grayscale value of the pixel point in each transparency map in the transparency map sequence, and the dissolved edge color is the color of the edge pixel point.

[0094] For each pixel point in the transparency map, if the calculation result is 0, then F1 is the preset original color, if the calculation result is 1, then F1 is the dissolved edge color, if the calculation result is between 0 and 1, then F1 is a linear interpolation of the preset original color and the dissolved edge color. For example, if the calculation result is 0.3, then F1 = preset original color * 0.3 + dissolved edge color * 0.7, and if the calculation result is 0.5, then F1 = preset original color * 0.5 + dissolved edge color * 0.5.

[0095] Step (0.01, calculation result) means that if the calculation result is less than 0.01, return 0, if the calculation result is greater than or equal to 0.001, return 1.
