[0052] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0053] In modern web design, light and shadow effects have become an important factor in improving user experience. As users' requirements for visual experience increase, traditional rendering technology with fixed subdivision levels is unable to meet their needs. Although this method is simple to implement and suitable for some basic scenarios, it has some obvious limitations when dealing with complex light and shadow effects.

[0054] First, in terms of rendering effects, fixed subdivision levels have difficulty dealing with areas with rich light and shadow changes, such as product detail pages on e-commerce websites. These pages often contain high-resolution product images and videos, and subtle differences in light and shadow effects may directly affect users' purchasing decisions. However, fixed subdivision levels cannot provide enough details, resulting in suboptimal rendering effects in high-contrast areas, and image details cannot be clearly displayed.

[0055] Secondly, fixed subdivision levels may lead to a waste of computing resources. In areas with less light and shadow changes, such as the text area of ​​the product details page, using high-precision rendering will cause unnecessary computing burden. This not only increases system overhead, but may also affect the loading speed and response performance of the web page.

[0056] Finally, existing rendering techniques lack the ability to adapt themselves and cannot dynamically adjust rendering strategies based on user behavior or environmental changes. When users browse the same content at different time periods, changes in ambient light should be reflected in the rendering effect. However, rendering methods with fixed subdivision levels lack this flexibility and cannot adjust according to real-time changes.

[0057] Therefore, in order to overcome these challenges and improve web page rendering effects, more adaptable rendering technologies need to be developed urgently. This will help optimize resource usage, improve user experience, and meet changing user needs.

[0058] Based on this, in an embodiment of the present invention, a method for dynamic light and shadow rendering of a website is provided, which aims to overcome the problems of fixed layout, static light and shadow effects, and waste of resources in traditional website rendering technology. The method combines the biomorphic optimization algorithm and cellular automata technology. Specifically, the website layout parameters are improved by the biomorphic optimization algorithm, and then the cellular automata are used to adjust the light and shadow effects of the website in real time according to the optimized parameters. In addition, the method continuously optimizes the parameters of the biomorphic optimization algorithm according to user behavior data. This comprehensive method ultimately realizes the adaptive subdivision rendering of dynamic light and shadow of the website, thereby effectively improving the user experience and optimizing resource utilization.

[0059] like Figure 1 As shown, a flowchart of an implementation of a website dynamic light and shadow rendering processing method provided by an embodiment of the present invention is provided. The method may include:

[0060] S100: Obtain current web page layout parameters of a web page of a target website, wherein the current web page layout parameters include visual attribute information of multiple elements on the target website.

[0061] Among them, web page layout parameters refer to a set of parameters used to define and describe the structure and organization of a web page. These parameters determine the position, size, alignment, and hierarchical relationship of each element in the web page.

[0062] Elements are the basic components of a web page. Each web page element can be an HTML tag such as text, image, video, button, form, link, etc.

[0063] Among them, visual attribute information refers to the attributes related to the appearance and visual performance of web page elements. Visual attribute information includes brightness, saturation, texture, etc. Visual attribute information determines the visual style of web page elements and the visual experience of users when browsing.

[0064] Optionally, the visual attribute information may include brightness and saturation of at least one of a product image area, a product video area, and a text description area on the webpage of the target website.

[0065] Specifically, the embodiment of the present invention can parse the webpage source code based on the initial structure data (HTML / CSS / JavaScript) of the webpage, extract the position, size, type and other information of all elements, and initialize the layout parameters according to the type and position of the element, including visual attribute information such as brightness, saturation, texture, etc.

[0066] The initialization setting of web page layout parameters is mainly based on the display requirements and performance requirements of elements. On e-commerce websites, product images, product videos and text descriptions are all important elements, and the visual attribute settings of each element have their own specific considerations. Product images are very important elements on e-commerce websites. High brightness can better display the details of the product, so high brightness and saturation are required to highlight the product and attract the user's attention. The content of the product video itself contains relatively rich color information, so there is no need to set too high brightness. In addition, since video content requires more computing resources to process and render than images and text, in order to balance performance, the brightness and saturation of the video are appropriately reduced. Text descriptions are mainly used for information transmission. In order not to interfere with other key elements, the brightness of the text is low while maintaining good readability. Therefore, product images require high brightness and saturation to highlight the product and attract the user's attention. The brightness and saturation of the product video are appropriately reduced to balance the rich color information and computing resource requirements. The brightness of the text description is low to ensure that it does not interfere with other key elements while maintaining readability. For example: for product images, the initial brightness is set to 0.8 and the saturation is 0.7; for product videos, the initial brightness is set to 0.6 and the saturation is 0.5; for the text description area, the initial brightness is set to 0.4.

[0067] The embodiment of the present invention uses web page layout parameter initialization, extracts web page elements by parsing web page structure data, and initializes web page layout parameters to provide basic parameters for subsequent optimization.

[0068] S110. Optimizing the current web page layout parameters using a predefined multi-objective function to obtain optimized web page layout parameters of the target website, wherein the multi-objective function is constructed based on a user attention model, a computational cost model, and a visual effect model.

[0069] In the scenario of optimizing the web page layout of an e-commerce website, it is necessary to consider the user's attention to different areas, the consumption of computing resources, and the overall visual effect. The multi-objective function is an optimization algorithm that combines the objectives of the user attention model, the computing cost model, and the visual effect model.

[0070] Among them, the user attention model targets the product image area in the web page. Product images are one of the most eye-catching elements on e-commerce websites. Users usually look closely at product images to understand the appearance and details of the product. The user attention model measures the user's attention to the area by calculating the sum of the attention scores of each cell in the product image area. The attention indicators involved in the user attention model include the user's gaze dwell time, click-through rate, and scrolling behavior.

[0071] Among them, the computational cost model targets the product video area in the web page. Video content requires more computing resources to process and render than images and text, especially at HD or full HD resolution. The computational cost model measures the computational cost by calculating the sum of the computational cost scores for each cell in the product video area. The computational cost model involves computational cost indicators that assess the impact of video playback on user device performance, such as CPU and memory usage, battery consumption, and data transfer volume.

[0072] Among them, the visual effect model targets the text description area in the web page. Although text descriptions are not as intuitive as pictures and videos to attract users, good text layout and design can enhance the overall visual aesthetics and help users better understand product information. The visual effect model measures the visual effect by calculating the sum of the visual effect scores of each cell in the text description area. The visual effect indicators involved in the visual effect model include font readability, color saturation matching, and layout clarity.

[0073] When optimizing the webpage layout of an e-commerce website, the user attention model, computational cost model, and visual effect model are evaluated for the product image area, product video area, and text description area respectively. Each model calculates the sum of the scores of each cell in the relevant area to help determine the best layout solution to balance user attention, computational resource consumption, and overall visual effect.

[0074] S120, dividing the web pages of the target website into a plurality of cell grids.

[0075] Each cell grid is a unit of a two-dimensional grid, and its size and number vary according to the type and characteristics of the web page content.

[0076] Specifically, the embodiment of the present invention can divide the web page into a two-dimensional grid, and each grid point is regarded as a "cell", that is, a cell grid. Different types of content areas are divided into cells of different numbers and sizes according to their characteristics.

[0077] Optionally, the embodiment of the present invention can subdivide the product image area in the webpage into 800x800 cells. Each cell is 1x1 pixel in size. The embodiment of the present invention can capture the user's attention distribution on the product image in detail through this high-resolution division method, helping to optimize the image display effect.

[0078] Optionally, the embodiment of the present invention can subdivide the video playback area in the webpage into 40x30 cells. Each cell represents an area in the video frame. The embodiment of the present invention can effectively measure the consumption of computing resources by video playback through this video division method, especially at high-definition or full-high-definition resolution.

[0079] Optionally, the embodiment of the present invention can subdivide the text description area in the webpage into 20x10 cells. Each cell represents a part of the text line. The embodiment of the present invention helps to evaluate the visual effect of text layout and design through this text division method, thereby improving the overall aesthetics of the page and the efficiency of information transmission.

[0080] Specifically, the embodiment of the present invention can initialize the cell state of each cell grid based on the optimized web page layout parameters obtained after multi-objective function optimization. For example, the cell grid in the product image area has a brightness of 0.9 and a saturation of 0.65 after state initialization. The cell grid in the video playback area has a brightness of 0.7 and a saturation of 0.45 after state initialization. The cell grid in the text description area has a brightness of 0.5 and a saturation of 0.6 after state initialization.

[0081] It should be noted that the state initialization of the cell grid is not a simple restoration to the initialization settings of the original web page layout parameters, but a refined initialization based on the layout parameters optimized by the multi-objective function. This means that the cell state of each cell grid has been integrated into the globally optimized layout parameters, ensuring that the state of each cell is consistent with the overall optimized layout parameters. State initialization ensures that each content area is re-optimized based on the consideration of the global layout parameters, thereby achieving a more precise optimization effect.

[0082] S130, for any cell grid: based on the first cell state of the cell grid and its cell neighbor grids at the current moment, combined with the optimized web page layout parameters, calculate the second cell state of the cell grid at the next moment.

[0083] The cell state refers to the parameter value that describes the visual properties of the cell grid. For example, the cell state of a cell grid can be a brightness value.

[0084] Among them, the cell neighbor grid is all neighboring cells that are in direct contact with the current cell grid, which can include neighboring cells located on the four sides of the current cell grid (up, down, left, right) and neighboring cells at the four corners (diagonal direction). This adjacency relationship constitutes a neighborhood surrounding the cell grid, in which each neighboring cell can influence or be influenced, thereby realizing the interaction and propagation of the state. For example, the cell neighbor grid can be the 8 adjacent cell grids around the current cell grid. In the framework of cellular automata, the cell state of the current cell will be affected by the state of its neighboring cells.

[0085] Optionally, the embodiment of the present invention may use a predefined cellular automaton state transition function, combined with the optimized web page layout parameters, the first cell state of the cell grid and its cell neighbor grids at the current moment, to calculate the second cell state of the cell grid at the next moment.

[0086] Among them, the cellular automaton state transition function is used to calculate the cell state of the next time step according to the state of the current and neighboring cells, and the optimized layout parameters. The cellular automaton state transition function can update the cell state according to the rules. For example: if the brightness of the neighboring cell is higher than the current cell, the brightness of the current cell increases. If the saturation of the neighboring cell is lower than the current cell, the saturation of the current cell decreases. The embodiment of the present invention utilizes the adaptive light and shadow effects of cellular automaton technology, which can adjust the visual presentation of the web page in real time according to the changes in ambient light and user preferences, providing users with a consistent high-quality visual experience.

[0087] Optional, in the above Figure 1 On the basis of one or more corresponding embodiments, another optional embodiment provided by the embodiment of the present invention, based on the first cell state of the cell grid and its cell neighbor grids at the current moment, combined with the optimized web page layout parameters, calculating the second cell state of the cell grid at the next moment may specifically include:

[0088] Input the first cell state of the cell grid and its cell neighbor grid at the current moment and the optimized web page layout parameters into the formula:

[0089]

[0090] The second cell state of the cell grid at the next moment is obtained, wherein: is the second cell state of the cell grid at the next moment, is the state transition function of the cellular automaton, is the cell grid at the current moment The first cell state; is the cell neighbor grid of the cell grid at the current moment The cell state set; is the optimized web page layout parameter.

[0091] The embodiment of the present invention uses cellular automaton technology to dynamically adjust the cell state of each cell grid according to the optimized layout parameters, thereby achieving a natural transition of local light and shadow effects.

[0092] The embodiment of the present invention combines the biomorphic optimization algorithm with the cellular automaton technology to achieve dynamic adjustment of the website's light and shadow to match the user's attention and behavior patterns, and at the same time achieves real-time optimization of the light and shadow effects through the cellular automaton technology. This method not only significantly improves the efficiency of computing resources and reduces energy consumption, but also ensures a smooth user experience under different devices and network environments.

[0093] S140. At the next moment, simultaneously update each cell grid from its respective first cell state to a corresponding second cell state, so as to dynamically render the light and shadow effects of the web page of the target website.

[0094] Specifically, the embodiments of the present invention can update the cell state of each cell grid by applying local rules, form a new visual effect, and realize dynamic rendering.

[0095] The present invention provides a method for processing dynamic light and shadow rendering of a website, the method comprising: obtaining the current webpage layout parameters of a webpage of a target website, wherein the current webpage layout parameters include visual attribute information of multiple elements on the target website; optimizing the current webpage layout parameters using a predefined multi-objective function to obtain the optimized webpage layout parameters of the target website, wherein the multi-objective function is constructed based on a user attention model, a computational cost model, and a visual effect model; dividing the webpage of the target website into a plurality of cell grids; for any cell grid: based on the first cell state of the cell grid and its cell neighbor grid at the current moment, combined with the optimized webpage layout parameters, calculating the second cell state of the cell grid at the next moment; at the next moment, simultaneously updating each cell grid from its respective first cell state to the corresponding second cell state, so as to dynamically render the light and shadow effects of the webpage of the target website.

[0105] Among them, the gradient of the multi-objective function is the objective function with respect to the current web page layout parameters The derivative vector of represents the direction and magnitude of the influence of each parameter on the objective function.

[0106] Figure 3 The figure shows a logic block diagram of web page layout parameter optimization provided by an embodiment of the present invention. The web page layout parameter optimization is based on the initial web page layout parameters to improve the light and shadow effects and save resources. Specifically, the layout parameters of web page elements are optimized through a multi-objective function to ensure that the layout parameters can meet the optimization requirements of the three aspects of user attention, computational cost model and visual effect model, so as to achieve the best layout effect.

[0107] Optional, in the above Figure 2 On the basis of one or more corresponding embodiments, in another optional embodiment provided by the embodiment of the present invention, the gradient of the multi-objective function is calculated, and the current web page layout parameters are updated using the gradient descent method to obtain the optimized web page layout parameters of the target website, which may specifically include:

[0117]

[0118] Update the current web page layout parameters according to the calculated gradient of the multi-objective function:

[0119]

[0120] in, is the learning rate, The updated web page layout parameters.

[0121] The learning rate is used to control the step size of each update. The choice of learning rate has an important impact on the speed and stability of the optimization process, and the optimal learning rate can be determined by experiment.
