Fig. 1 illustrates an exemplary system architecture 100 to which embodiments of the special effects rendering method, apparatus, electronic device, and computer-readable storage medium of the present disclosure may be applied.
As shown in fig. 1, the system architecture 100 may include user terminals 101, 102, 103, a network 104, and a server 105. The network 104 serves as a medium for providing communication links between the user terminals 101, 102, 103 and the server 105. Network 104 may include various connection types, such as wired, wireless communication links, or fiber optic cables, to name a few.
A user may use the user terminals 101, 102, 103 to interact with the server 105 over the network 104 to receive or send messages or the like. The user terminals 101, 102, 103 and the server 105 may be installed with various applications for implementing information communication between the two, such as a special effect rendering application, an image resource transmission application, an instant messaging application, and the like.
The user terminals 101, 102, 103 and the server 105 may be hardware or software. When the user terminals 101, 102, 103 are hardware, they may be various electronic devices with display screens, including but not limited to smart phones, tablet computers, laptop portable computers, desktop computers, and the like; when the user terminals 101, 102, 103 are software, they may be installed in the electronic devices listed above, and they may be implemented as a plurality of software or software modules, or implemented as a single software or software module, and are not limited in this respect. When the server 105 is hardware, it may be implemented as a distributed server cluster composed of multiple servers, or may be implemented as a single server; when the server is software, the server may be implemented as a plurality of software or software modules, or may be implemented as a single software or software module, which is not limited herein.
The user terminals 101, 102, and 103 may provide various services through various built-in applications, and taking a special effect rendering application that may provide a special effect rendering service for the user together with the server 105 as an example, the user terminals 101, 102, and 103 may achieve the following effects when running the special effect rendering application: firstly, receiving a special effect rendering request transmitted by a user through a browser application installed on an operating system; then, determining a target special effect corresponding to the image to be rendered according to the special effect rendering request; next, calling a first renderer configured on the browser application to perform partial rendering on an image to be rendered according to the target special effect to obtain a first rendering result; next, presenting a first rendering result to a user who initiates the special effect rendering request, and expecting to receive indication information whether the user confirms or not, wherein the indication information is transmitted by the user again; when the first rendering result is confirmed by the user, a complete rendering instruction including the image to be rendered and the target special effect is issued to the server 105, so that the server 105 invokes a second renderer configured locally to perform complete rendering on the image to be rendered according to the target special effect, and returns a second rendering result obtained by rendering to the user terminals 101, 102, and 103, wherein the first renderer and the second renderer are products obtained after the same rendering engine is adapted to the characteristics of different terminals.
The special effect rendering methods provided in the subsequent embodiments of the present disclosure are generally executed by the user terminals 101, 102, and 103 directly facing the user, and accordingly, the special effect rendering apparatuses are also generally disposed in the user terminals 101, 102, and 103.
It should be understood that the number of user terminals, networks and servers in fig. 1 is merely illustrative. There may be any number of user terminals, networks, and servers, as desired for an implementation.
Referring to fig. 2, fig. 2 is a flowchart of a special effect rendering method according to an embodiment of the disclosure, where the process 200 includes the following steps:
step 201: determining a target special effect corresponding to an image to be rendered according to a special effect rendering request transmitted from a webpage end;
this step is intended to determine an image to be rendered and a selected rendering manner as a rendering target from an incoming special effect rendering request by an execution subject of the special effect rendering method (e.g., user terminals 101, 102, 103 shown in fig. 1). The special effect rendering request is transmitted by a user through a browser webpage, and the webpage is a webpage which is opened in a browser application installed in the execution main body operating system and provides special effect rendering service.
The special effect rendering request at least comprises an image to be rendered and a target special effect, wherein the image to be rendered exists as a rendering target, and the target special effect is a special effect parameter indicating which special effect rendering is performed on the rendering target by a user, and can be represented as a certain special effect plug-in, a special effect filter or a certain using mode of a certain special effect filter. The image to be rendered may be obtained by selecting a local file by a user or temporarily calling a camera to capture the image and then uploaded to the web page, or a network address pointing to a certain image may be directly input to the web page, which is not specifically limited herein.
Step 202: calling a first renderer configured at a webpage end to partially render an image to be rendered according to a target special effect to obtain a first rendering result;
on the basis of step 201, the execution subject calls a first renderer configured at the web page end to partially render an image to be rendered according to a target special effect, so as to obtain a first rendering result.
The first renderer is configured in the browser application of the execution body and can be called by a webpage providing a special effect rendering service, and partial rendering is performed on an image to be rendered according to a target special effect, so that a user can see a rendering effect of the selected target special effect under the condition that rendering time is reduced as much as possible, and the user can reselect and re-render the image with less cost when the rendering effect is not satisfactory.
For this purpose, it is also important to render which part of the image to be rendered, since it is desirable to select the part that, after rendering, is as intuitive as possible for the user to see the rendering effect, otherwise it is useless to render even a part. When a part to be rendered is selected, factors such as the image content type, the size, the number of objects appearing in the image, the position relation and the like of the image to be rendered can be combined for selection, so that a representative part image is selected as much as possible for rendering in the step.
Step 203: in response to the confirmation of the first rendering result by the initiating end of the special effect rendering request, controlling a second renderer configured at the server end to perform complete rendering on an image to be rendered according to the target special effect to obtain a second rendering result;
on the basis of step 202, in this step, when the first rendering result is confirmed by the initiating end of the special effect rendering request, the execution main body controls the server to invoke the second renderer to perform complete rendering on the image to be rendered according to the target special effect, that is, complete rendering of the image to be rendered is completed as soon as possible by means of the strong rendering performance of the server, so as to obtain a second rendering result.
Specifically, after the execution main body obtains the first rendering result, an initiating path of the special effect rendering request may be determined, and then the first rendering result is returned through a return path corresponding to the initiating path, so that the first rendering result is displayed to a user initiating the rendering request, so as to receive indication information indicating whether the returned indication satisfies the currently selected special effect rendering effect, and then different subsequent branches are selected according to the indication information. If the indication information indicates that the rendering effect shown by the first rendering result is not satisfied, prompt information for requesting the user to reselect a new target special effect may be returned.
Specifically, the execution main body issues a special effect rendering instruction that also includes an image to be rendered and a target special effect to a server (for example, the server 105 shown in fig. 1), so that the server invokes a second renderer configured by the server according to the received special effect rendering instruction to perform complete special effect rendering on the image to be rendered according to the target special effect, thereby obtaining the second rendering result. Or issuing a special effect rendering instruction which does not contain the image to be rendered and the target special effect but contains the index information to the server, so that the server can obtain the image to be rendered and the target special effect at the position indicated by the index information according to the index information contained in the instruction.
It should be noted that, in the present disclosure, the first renderer is configured at the web page side of the execution main body (i.e., configured on the browser application), and the second renderer is configured at the server side, except for different configuration positions, the first renderer and the second renderer have the same bottom-layer rendering engine (which may also be referred to as a rendering algorithm and a rendering frame), and the same rendering engine is adapted to the difference in the operational performance between the web page side and the server side to obtain a product. Therefore, the first rendering result obtained by the first renderer and the second rendering result obtained by the second renderer have the same rendering effect on the same image content, so that the second rendering result is actually represented as a full version of the first rendering result.
Step 204: and controlling the server to return the second rendering result to the initiating end.
On the basis of step 203, this step is intended to control the server to return the second rendering result to the initiating end by the executing entity, so that the initiating end (or initiating user) actually initiating the special effect rendering request finally obtains the desired complete rendering result.
When a special effect rendering request is received, the special effect rendering method provided by the embodiment of the disclosure calls a first renderer configured at a webpage end to perform partial rendering on an image to be rendered to obtain a first rendering result for previewing a rendering effect for an initiating end without giving a large rendering pressure to the webpage end with poor performance, and after the initiating end confirms the rendering result of the first rendering result, controls a second renderer configured at a server end to perform complete rendering on the image to be rendered to efficiently complete the complete rendering by virtue of strong operational capability of the server end, and controls the first renderer and the second renderer to be developed based on the same rendering engine, so that the rendering effect of the second rendering result can be ensured to be consistent with the previously seen rendering effect of the first rendering result, the success rate of one-time rendering is increased, and operational resources are saved, The overall utilization rate of the operation resources is improved.
Aiming at how to reasonably determine the partial images to be rendered in the complete images to be rendered, the disclosure also provides different implementation schemes respectively for two common types of images to be rendered through fig. 3 and fig. 4, so as to render the partial image content with a special effect as representative as possible. FIG. 3 illustrates a partial rendering scheme for a portrait, wherein the flow 300 includes the steps of:
step 301: responding to the image to be rendered as a whole-body photographic image containing a human face, and determining a human face part in the whole-body photographic image;
step 302: and calling a first renderer configured at the webpage end to render the human face part according to the target special effect.
For the special effect rendering requirement of the human image class, considering that the viewers usually pay more attention to face information, and the face is the most eyeball part of the viewers, the embodiment takes the face part in the whole-body-shot image as the object for performing partial rendering, and combines the proportion of the face in the whole-body shot, so that the rendering time consumption can be effectively reduced while the representativeness is satisfied.
Of course, in some special scenes, the emphasis of the viewer may be changed or the rendering emphasis is not on the face, and when the guidance information exists, the object to be partially rendered should be flexibly adjusted according to the guidance information.
FIG. 4 illustrates a partial rendering scheme for a landscape, wherein the flow 400 includes the steps of:
step 401: determining that the regional sub-image with the largest number of objects exists in the landscape image in response to the image to be rendered being the landscape image containing a plurality of objects;
step 402: and calling a first renderer configured at the webpage end to render the area sub-images according to the target special effect.
Different from the portrait with a prominent key point, the landscape image often contains a plurality of objects, and it is difficult to determine which object is more suitable to be used as a representative object to render only the representative object, so in order to ensure that a partial rendering result can provide more rendering effect feedback for a user as much as possible, the regional sub-image with the largest number of objects in the landscape image is determined as a partial rendering object, so that the rendering effect covers as many objects as possible, the user can see the rendering effect on different objects, and the effectiveness of the first rendering result is ensured.
Images to be rendered, which contain other types of image content, may be adaptively adjusted according to the guiding concept of finding representative parts embodied in the above discussion, which is not listed here.
If there is explicit rendering emphasis indication information accompanying the special effect rendering request, determining a part related to rendering emphasis in the image to be rendered according to the rendering emphasis indication information, and taking the part as a rendering object to obtain a first rendering result. If the directly given rendering key point indication information cannot be acquired, statistics and analysis can be performed according to the historical special effect rendering request containing the rendering key point indication information, so that the probability that each part in the image belongs to the rendering key point is predictively determined according to the analysis result, and the partial image with higher probability is selected for rendering. Specifically, the tool for performing statistics and analysis may use a linear or non-linear classifier, a deep learning algorithm, and the like, and is not limited herein.
Since the target special effect can be expressed in various forms, to enhance the understanding of this part of the scheme, this embodiment also specifically takes a special effect filter as an example, and a specific implementation scheme for determining the target special effect is given in conjunction with fig. 5, where the process 500 includes the following steps:
step 501: receiving a special effect rendering request transmitted by an initiating terminal through a browser webpage;
step 502: determining an image to be rendered and special effect filter selection information according to the special effect rendering request;
step 503: and determining a target special effect filter applying a special effect to the image to be rendered according to the special effect filter selection information.
That is, in this embodiment, the special effect rendering request specifically includes the image to be rendered and the special effect filter selection information, and the special effect filter selection information may be expressed as a number, a code, a name, and the like of a certain special effect filter or a certain type of special effect filter, so that the execution main body can accurately apply a target special effect filter of a target special effect to the image to be rendered according to the special effect filter selection information.
The target special effects of other expressions can also be adaptively adjusted according to the logic of the embodiment.
As can be seen from the content described in any of the embodiments, the first renderer at the web page side and the second renderer at the server side cooperate with each other to ensure that the second rendering result and the first rendering result show the same rendering effect, so that when an update instruction for any one of the first renderer and the second renderer is received, the same update needs to be performed on the other renderer at the other matched end, so as to ensure that the same rendering effect can be maintained before and after the update. Taking the example of receiving an update indication for the second renderer, the following is given for one implementation including, but not limited to:
in response to receiving an update indication for the second renderer, determining updatable state information for the first renderer;
in this embodiment, the updatable status information is determined based on the progress status of the rendering task currently received by the web page, and includes a non-update permitted status corresponding to the rendering task still being performed, and an update permitted status corresponding to the rendering task not being performed.
And responding to the update permission state of the updatable state information, correspondingly updating the second renderer and the first renderer according to the update indication, and otherwise, confirming that the first renderer cannot be updated currently and waiting until the updatable state information is changed into the update permission state.
That is, the present embodiment additionally introduces a judgment on the timing of allowing the synchronous update, so as to avoid the problem of different rendering effects caused by asynchronous update.
In order to deepen understanding, the disclosure also provides a specific implementation scheme by combining a specific application scenario:
1. a user transmits a special effect rendering request to a browser webpage providing special effect rendering service through a smart phone held by the user;
2. calling a WebGL image processing frame configured in a browser application based on a webpage operated by the browser application, and performing partial rendering on a selected part of an image to be rendered according to a target special effect filter to obtain a first rendering result;
specifically, a Shader of the WebGL image processing framework may be invoked to perform a partial shading rendering of the selected portion of the image to be rendered according to the target special effect filter.
3. The webpage displays the first rendering result to a user through a display screen of the smart phone; 4. confirming whether the seen first rendering result meets the expectation by the user;
5.1, when the user considers that the rendering effect shown by the first rendering result meets the expectation, returning a confirmation instruction to the smart phone;
5.2, when the user considers that the rendering effect shown by the first rendering result does not meet the expectation, returning a return instruction to the smart phone, and skipping to the step 1 again to resend the special effect rendering request containing the new target special effect information;
6. the smart phone forwards the confirmation instruction to the webpage through browser application, and the server under the webpage sends a special effect rendering request for completely rendering the image to be rendered according to the target special effect filter;
7. the server calls an OpenGL image processing framework which is pre-configured in the local, and complete rendering is carried out on the image to be rendered according to the target special effect filter, so that a second rendering result is obtained;
specifically, a Shader of the OpenGL image processing framework may be invoked to render the selected portion of the image to be rendered in a color based on the target special effect filter.
8. The server returns the second rendering result to the smart phone;
9. and the smart phone displays the received second rendering result to the user through a display screen.
That is, in this embodiment, a Web Graphics Library (Web Graphics Library, which may be understood as a combination of a JavaScript frame and OpenGL often used at a Web page end to enable the Web page end to be called to achieve a processing effect of OpenGL) image processing frame is configured at a Web page end, and an OpenGL image processing frame is directly configured at a server end, so that the two frames can keep the same part of the same image to obtain the same rendering effect when using the same special effect filter, and both frames actually use a set of shaders for performing rendering.
In addition to the scheme of matching WebGL with OpenGL shown in this embodiment, other similar solutions may also be used, for example, a processing framework for performing special effect rendering directly on pixel point data in a color space in a pixel point manner only needs to ensure that the web page side and the server side are performed in the same color space.
