[0049] Overview
[0050] As described in the background technology, in software rendering technology, scene switching is usually accompanied by loading delays and abrupt visual changes, which greatly reduces the smoothness and immersion of the user experience. In related technologies, the above problems can be alleviated by preloading and adding transition animations. However, they usually rely on pre-made animation materials, which are fixed and cannot be adjusted according to the real-time state of the current scene, resulting in abrupt jump cuts in scene transitions. The effects are often highly complex and the transition effects are limited, and smooth and attractive visual switching between scenes cannot be achieved.
[0051] Therefore, there is an urgent need to provide a scene switching method to solve the problem in the related art that scene switching cannot be flexibly adjusted and smooth and attractive visual switching between scenes cannot be achieved during the transition.
[0052] In order to solve the problem that scene switching cannot be flexibly adjusted and smooth and attractive visual switching between scenes cannot be achieved during transition, in the technical solution of the present application, when determining to switch from the first scene to the second scene, the scene switching method obtains the first still frame displayed by the first scene, then generates and plays the first light effect animation based on the first still frame, then obtains the second still frame to be displayed by the second scene, generates the second light effect animation based on the second still frame, and finally plays the second light effect animation, and switches to the second scene after the second light effect animation is played. The transition animation can be generated in real time according to the state of the current scene, thereby improving the flexibility and real-time performance of scene switching, and at the same time providing a smoother and more immersive visual experience, thereby improving the consistency and enjoyment of use.
[0053] Based on the above inventive concept, the scene switching method provided in the implementation manner of this specification is exemplarily described below.
[0054] Exemplary Methods
[0055] The embodiments of this specification provide a scene switching method, which can be applied to smart devices with real screens, such as Figure 1 As shown, including:
[0056] S101: When determining to switch from a first scene to a second scene, obtain a first still frame displayed by the first scene.
[0057] Specifically, it can respond to a background program call or a user's switching operation, that is, determine to switch from the first scene to the second scene. When choosing to enter the switching scene, that is, when the first scene currently being displayed is about to switch to the second scene, a still frame of the picture displayed by the current first scene is obtained. Still frame pictures refer to images that do not contain motion or dynamic effects in visual communication, and are usually used to convey information, tell stories, or display works of art. Still frames can include but are not limited to photos, illustrations, charts and infographics, posters, etc. In the present invention, still frames serve as basic data for generating light effect animations for scene transitions in subsequent steps.
[0058] In this step, the scene is a virtual environment or space that protects multiple elements and objects, and is intended to be rendered and displayed through computer graphics technology. The first scene is the scene currently being displayed, and the second scene is the scene to be switched to. In an example, such as level switching in a video game, switching from the current first level to the next level, or room switching in a virtual reality application, switching between different angles in architectural visualization or animation, scene transitions in a movie, etc.
[0059] S102: Generate and play a first light effect animation according to the first still frame.
[0060] In this step, the first feature information in the first still frame is obtained by performing feature extraction on the first still frame, and the first light effect animation is generated by using the first feature information. During the specific extraction, advanced image processing technology can be used to systematically analyze the visual elements of the current picture, identify the first feature information such as the main objects, background, contour lines, and then generate the first light effect animation based on the first feature information.
[0061] Specifically, the first light effect animation may include multiple animation types, such as dynamic contour line, color contour line animation, particle effect animation, shape transformation animation, interactive contour line animation, etc. The above animation types are briefly introduced as follows:
[0062] Dynamic contours: This type of animation can animate the extracted contours so that they move, rotate or deform according to a certain pattern, thus creating a dynamic visual effect. In one example, the contours can rise and fall like waves or rotate and rise like a spiral.
[0063] Color contour line animation: This type of animation adds different colored line animations to the contour line, making the contour line present a colored line effect during playback. By setting different colors and animation effects, the contour line presents rich color changes during playback.
[0064] Particle effect animation, this type of animation uses the particle system to generate a particle flow effect along the contour line. The particles can flow up and down the contour line to form a unique visual effect. This effect can be customized by adjusting the color, size, speed and other parameters of the particles.
[0065] Shape transformation animation, this type of animation splits the outline into multiple parts, and then adds different animation effects to each part, such as erasing, fading in and out, etc., to create a shape transformation animation effect. This method can be used to create complex animation effects, such as gradual stroking of outlines.
[0066] Interactive contour animation, this type of animation combines interactive design elements, such as buttons, sliders, etc., so that the audience can control the playback, pause, acceleration, etc. of the contour animation through operations. This interactive design can enhance the audience's sense of participation and experience.
[0067] At the same time, other effects can be superimposed in the first light effect animation, such as making the picture of the first scene gradually disappear with the animation, creating a visual guidance and transition effect. At the same time, other animation forms can be selected as replacements, such as particle dissipation, mask dissipation, light effect elimination, etc. The following is a brief introduction to the above animation types:
[0068] Particle dissipation, in this type of animation, the particle dissipation effect is usually used to create a dreamy, mysterious or technological atmosphere. It achieves the effect of disappearance by decomposing the picture into countless tiny particles and then gradually dissipating them.
[0069] Mask dissipation, in this type of animation, a mask layer is added to the screen, and the mask layer is completely covered by the original screen through scaling and positioning to make the original screen disappear. The mask layer can be a simple shape, LOGO, or other special patterns.
[0070] Light effect elimination: In this type of animation, by adding light effect elements (such as light, light spots, etc.) to the picture, the light effect changes from weak to strong and then to weak again, making the original picture disappear. This effect can simulate the changes in light in nature, such as sunset, sunrise or lights going out.
[0071] It should be noted that the animation types can be increased, decreased and modified according to actual needs, and the embodiment of the present invention does not limit this.
[0072] S103: Acquire a second still frame image to be displayed for the second scene, and generate a second light effect animation according to the second still frame image.
[0073] In this step, firstly, the second still-frame image to be displayed in the second scene is obtained. Specifically, during operation, the second scene can be run in the background. Specifically, the data and resources of the second scene are asynchronously loaded through the background thread, that is, there is no conflict with the loading of the first scene. Of course, other processing methods can also be used to load the second scene without affecting the operation of the first scene, thereby obtaining the first still-frame image of the second scene, that is, the second still-frame image.
[0074] After obtaining the second still frame, feature extraction is performed on the second still frame to obtain second feature information in the second still frame, and the second light effect animation is generated using the second feature information. During the specific extraction, advanced image processing technology can be used to systematically analyze the visual elements of the current image, identify the second feature information such as the main objects, background, contour lines, etc., and finally generate the second light effect animation based on the second feature information.
[0075] Specifically, the second light effect animation can include many types of animations, such as dynamic light effect inflow and screen gradual display, color gradient animation, shape decomposition and reorganization, particle aggregation display, interactive display, dynamic background switching, etc. The following is a brief introduction to the above animation types:
[0076] Dynamic light effects flow in and the picture gradually appears. In this light effect animation, a bright spot first appears in the center of the screen. As the light effect expands, the surrounding pictures gradually appear, forming a gradient effect. Specifically, when a new picture appears, the light effect can be used to spread from the center of the picture to the surroundings. The light effect spreads outward like ripples, gradually revealing new picture content.
[0077] Color gradient animation: In this light effect animation, the color gradient can be used to increase the visual appeal before the new picture is displayed. The picture gradually changes from a single color to a rich color, and finally a new picture appears. For example, the picture is initially light blue, and as the gradient changes, it gradually turns into colorful colors, and finally shows new content.
[0078] Shape decomposition and reorganization: In this light effect animation, the elements of the new picture can be realized by splitting them into multiple shapes. First, the old picture is decomposed into small pieces, and then these small pieces are reassembled into the shape of the new picture. For example, the old picture looks like a puzzle. Figure 1 The image gradually breaks into pieces, each piece then flies in different directions before eventually reassembling into a new image.
[0079] Particle aggregation display: In this light effect animation, a new picture is gradually aggregated through particle effects. Particles gather from the edge of the screen to the center, and a new picture is formed in the process of aggregation. For example, small particles fly from the four corners to the center, and as the particles gather, a new image gradually appears.
[0080] Interactive display, in which the light effect animation combines interactive elements, such as the user clicking a button or a slider to trigger the display of a new screen, to enhance the user's sense of participation. In one example, when the user clicks the "Continue" button on the screen, a new screen slowly appears with light and sound effects, providing an interactive experience.
[0081] Dynamic background switching. In this light effect animation, the dynamic background gradually blurs during the transition, and then the new picture is clearly displayed. For example, when a new picture appears, the dynamic background switching effect is used, such as switching from a dynamic scene (such as flowing water or clouds) to a new picture.
[0082] S104: Play the second light effect animation, and switch to the second scene after the second light effect animation is played.
[0083] In specific implementation, the second scene is switched after playing the second light effect animation. It should be noted that the first light effect animation and the second light effect animation can dynamically adjust the playing speed to adapt to the background operation status or current operation logic, and the embodiment of the present invention does not limit this.
[0084] By using the method provided in this embodiment, a transition animation can be generated in real time according to the state of the current scene. This not only improves the flexibility and real-time performance of scene switching, but also provides viewers with a smoother and more immersive visual experience. In this way, the transition of each scene can be perfectly integrated with the previous and the next, greatly improving the continuity and enjoyment of viewing.
[0085] The following is an example of an optional implementation method to illustrate the specific implementation process of the scene switching method of the present application. Figure 2 , the scene switching method may include:
[0086] S201: When determining to switch from a first scene to a second scene, obtain a first still frame displayed by the first scene.
[0087] Specifically, it can respond to a background program call or a user's switching operation, that is, determine to switch from the first scene to the second scene. When selecting to enter the switching scene, that is, when the first scene currently being displayed is about to switch to the second scene, a still frame of the picture displayed by the current first scene is obtained, and the still frame is used as the basic data for generating the light effect animation for scene transition in the subsequent steps.
[0088] S202: Extract first feature information of the first still frame.
[0089] In this step, by extracting features from the first still frame, first feature information in the first still frame is obtained. For example, by using advanced image processing technology, the system analyzes visual elements of the current image and identifies first feature information such as main objects, backgrounds, and contours. Specifically, the feature information that can be extracted is as follows:
[0090] Color features: such as color histogram, color moment, etc.
[0091] Texture features: such as gray-level co-occurrence matrix (glcm), local binary pattern (lbp), etc.
[0092] Shape features: such as edge detection, Hough transform, etc.
[0093] Semantic features: Identify objects or scenes in images through pre-trained deep learning models.
[0094] S203: Determine a first light effect animation type and a first contour line of a first still frame according to the first feature information.
[0095] In specific implementation, the first light effect animation type and the first contour line are determined respectively through the first feature information. When determining the first contour line, the edge detection algorithm is used to accurately locate the edge of the object identified in step S202. These edges constitute the basic contour line of the picture, so as to accurately extract the contour line of the static frame picture. In addition, the extraction of the contour line can be adjusted in real time according to the dynamic changes of the picture to ensure that the most accurate boundary information can be captured when the scene is switched. This process not only enhances the coherence of the visual effect, but also provides necessary data support for the subsequent light effect animation generation.
[0096] When determining the first light effect animation type, the extracted features are first analyzed to determine which features are significant. For example, if the image is mainly a certain color (such as blue), it can be considered that this is a significant color feature. If the image contains a large number of straight lines and corners, it can be considered that this is a significant shape feature. Then based on the results of the feature analysis, decide how to select animation effects based on the features. In one example, if the color feature is significant, a color contour animation can be selected. If the shape feature is significant, a contour flow animation or a specific graphic contour animation can be selected. Then select a suitable first light effect animation type from the available special effects animation library. Of course, the effect of the special effects animation after the first light effect animation type can also be determined by observation, and the method of feature extraction and analysis, as well as the rules for special effect selection can be adjusted as needed. This process may require multiple iterations to achieve the best effect.
[0097] In an example, assuming that there are the following six animation modes, namely, contour flow animation, specific graphic contour animation, colored contour animation, particle special effects animation, shape deformation animation, and interactive contour animation, then if the edge density of the image is high and the length distribution is uniform, select the contour flow animation. If the proportion of a specific shape (such as a circle or rectangle) in the image exceeds the threshold, select the specific graphic contour animation. If the image is rich in color and has obvious edges, select the colored contour animation. Particle special effects animation: If the image is rich in details and has no obvious dominant shape or color, select the particle special effects animation. If the shape in the image changes significantly over time, select the shape deformation animation. If continuous user interaction is detected, select the interactive contour animation.
[0098] S204: Based on the first light effect animation type, generate and play a first light effect animation using a first contour line.
[0099] In the above steps, the first light effect animation type is determined, and then the first light effect animation is generated using the first contour line. In one example, when the first light effect animation type is a dynamic contour line, the extracted contour line is dynamically processed so that it moves, rotates or deforms according to a certain rule, thereby creating a dynamic visual effect. When the first light effect animation type is a color contour line animation, line animations of different colors are added to the contour line so that the contour line presents the effect of color lines during playback. By setting different colors and animation effects, the contour line presents rich color changes during playback. When the first light effect animation type is a particle effect animation, a particle system is used to generate a particle flow effect along the contour line, and the particles can flow up and down the contour line to form a unique visual effect. This effect can be customized by adjusting the color, size, speed and other parameters of the particles. When the first light effect animation type is a shape transformation animation, the contour line is split into multiple parts, and then different animation effects are added to each part, such as erasing, fading in and out, etc., to create a shape transformation animation effect. This method can be used to create complex animation effects, such as gradual tracing of contours. When the first light effect animation type is an interactive outline animation, this type of animation is combined with interactive design elements, such as buttons, sliders, etc., so that the audience can control the play, pause, acceleration, etc. of the outline animation through operations. This interactive design can enhance the audience's sense of participation and experience.
[0100] S205: Obtain a second still frame image to be displayed for the second scene, and extract second feature information of the second still frame image.
[0101] In this step, firstly, the second still-frame image to be displayed in the second scene is obtained. Specifically, during runtime, the second scene can be run in the background. Specifically, the data and resources of the second scene are asynchronously loaded through the background thread to obtain the first still-frame image in the second scene, i.e., the second still-frame image.
[0102] After obtaining the second still frame, feature extraction is performed on the second still frame to obtain second feature information in the second still frame, and the second light effect animation is generated using the second feature information. During the specific extraction, advanced image processing technology can be used to systematically analyze the visual elements of the current image, identify the second feature information such as the main objects, background, contour lines, etc., and finally generate the second light effect animation based on the second feature information.
[0103] S206: Determine a second light effect animation type and a second contour line of the second still frame according to the second feature information.
[0104] In specific implementation, the second light effect animation type and the second contour line are respectively determined by the second feature information. When determining the second contour line, the edge detection algorithm is used to accurately locate the edges of the object identified in step S202. These edges constitute the basic contour line of the picture, thereby accurately extracting the contour line of the still frame picture.
[0105] S207 . Based on the second light effect animation type, generate a second light effect animation using a second contour line.
[0106] The specific generation logic is similar to that of S204 and will not be repeated here.
[0107] S208: Play the second light effect animation, and switch to the second scene after the second light effect animation is played.
[0108] In specific implementation, the second scene is switched after playing the second light effect animation. It should be noted that the first light effect animation and the second light effect animation can dynamically adjust the playing speed to adapt to the background operation status or current operation logic, and the embodiment of the present invention does not limit this.
[0109] In this embodiment, the contour line is obtained through the feature information, and then a suitable light effect animation is generated, which greatly improves the viewing continuity and enjoyment.
[0110] The specific implementation process of the scene switching method of the present application is illustrated below by another optional implementation method. Figure 3 , the scene switching method may include:
[0111] S301: When determining to switch from a first scene to a second scene, obtain a first still frame displayed by the first scene.
[0112] S302: Extract first feature information of the first still frame.
[0113] S303: Generate and play a first light effect animation according to the first still frame and a preset target still frame.
[0114] During specific implementation, the first light effect animation is generated according to the pre-set target still frame and the first still frame. The target still frame can be set by the system, or determined by determining the first light effect animation type of the first still frame, or can be a picture set by the user. Specifically, during generation, the first still frame is used as the initial frame of the first light effect animation, and the target still frame is used as the end frame of the first light effect animation to generate the first light effect animation. A variety of customized settings can be provided to increase flexibility.
[0115] S304: Obtain a second still frame image to be displayed for the second scene.
[0116] S305: Generate a second light effect animation according to the second still frame and the target still frame.
[0117] During specific implementation, the second light effect animation is generated based on the pre-set target still frame and the second still frame. Specifically, during generation, the target still frame is used as the initial frame of the first light effect animation, and the second still frame is used as the end frame of the first light effect animation to generate the second light effect animation. A variety of customized settings can be provided to increase flexibility.
