The parameters corresponding to different levels have different values, and the parameters corresponding to the same level have the same value. When the application is running, you can choose the parameters corresponding to a level for rendering.

Detailed ways

The embodiment of the present application can be applied to the rendering system shown in FIG. 1 , where the rendering system includes a terminal device, a first server, a second server, and a test device.

The terminal device may be referred to as a terminal for short, and may be a smart phone, a tablet computer, a notebook computer, a desktop computer, and a vehicle-mounted device. An application program is deployed in the terminal device, and the application program may be a three-dimensional (Three Dimensions, 3D) application program, specifically a game-like 3D application program.

In the terminal, when the application is running, it will be rendered using various rendering characteristics. Wherein, the rendering characteristic may be understood as a method of rendering with certain rendering parameters to produce a certain visual effect; for example, the visual effect may be a special effect (bloom) of a lamp, or may be motion blur.

The first server is used to query the value of the parameter required by the rendering feature from the second server, and provide the value of the parameter to the terminal, and the number of the first server is usually one.

The second server may also be referred to as a test server, and is used for testing the values of the parameters required by the rendering characteristics, and for storing the values of the parameters required for the rendering characteristics obtained from the test.

There may also be multiple second servers, wherein FIG. 1 shows two second servers; during the test, each second server can control at least one test device for testing.

The test device is used to test the values of the parameters required by the rendering feature, so as to obtain more suitable values of the parameters. The test device can be a server or a terminal device; when the test device is a server, the test device can run a virtual machine to test the value of the parameters required for rendering features; when the test device is a terminal, it can realize Test the values of the parameters required by the rendering feature locally on the terminal.

It should be noted that when the test equipment is a terminal, in order to obtain the values of parameters suitable for various terminals, the number of test equipment is usually multiple; for example, taking a mobile phone as an example, the test equipment can include as many types of mobile phones as possible , wherein Figure 1 shows three mobile phones.

The process of testing the value of the parameter by the second server and the testing device (mobile phone) will be described below.

First, when developing an application, the developer will construct a description file of the rendering scene, and the description file of the rendering scene includes description information of the rendering scene. As shown in Figure 2, the description information of the rendered scene includes the detailed description information of the mesh Mesh model, material or texture, lighting, and all rendering features in the application; Figure 2 shows rendering feature 1, rendering feature 2, and rendering Feature 3 These three rendering features.

Specifically, in the description file of the rendered scene, an extras field (used to indicate additional information) can be added, and detailed description information of the rendering feature can be added in the extras field; the detailed description information of the rendering feature can include the feature name featurename, The type type of the rendering feature, the address testserver of the test server required for the rendering feature, and the description information of the parameters required for the rendering feature. The description information of the parameters required for the rendering feature can be added by adding a new field, which can include rendering The parameter name paraname required by the feature, the parameter type "datatype" required by the rendering feature, the value of the parameter required by the rendering feature, etc.

For example, the attribute name of the rendering attribute is "bloom_hdr"; the type of the rendering attribute is "postProcessing", which specifically indicates that the type of the rendering attribute is post-processing; the field name of the parameter required by the rendering attribute is "Number of Gaussian Blur Iterations", and the rendering attribute Required parameter type is 'int'.

In FIG. 2 , taking the rendering feature 1 as an example, the description information of the rendering feature 1 may include the name of the rendering feature 1, the names of the parameters required by the rendering feature 1, and the values of the parameters required by the rendering feature 1.

Then, the developer will send the description file of the rendering scene to the test server (that is, the first server in Figure 1), and the test server will run the server-side rendering test program after receiving the description file of the rendering scene, and then send the rendering scene The description information of the rendered scene in the description file is sent to multiple different mobile phones.

Each mobile phone runs a mobile-side rendering test program. After receiving the description information of the rendering scene, it will traverse each parameter, and continuously test the rendering effect by modifying the value of the parameters required for rendering characteristics, so as to obtain the results obtained in the test. The value of the parameters required for the rendering characteristics with better rendering effects on the current mobile phone; Among them, there are many schemes for traversing the parameters, which are not specifically limited in this embodiment of the application, which may include sequential traversal or optimal traversal according to rendering Strategy to traverse; the scheme of the traverse parameters can be selected by the developer when uploading the description file of the rendered scene.

For example, as shown in Figure 3, after receiving the description information of the rendering scene, the test server runs the rendering test program, and controls the three mobile phones of mobile phone 1, mobile phone 2 and mobile phone 3 to test; The value of the parameter required for the rendering characteristic with good effect, the value of the parameter required for the rendering characteristic with good rendering effect in mobile phone 2, and the value of the parameter required for the rendering characteristic with good rendering effect in mobile phone 3.

It should be noted that developers can set different rendering types for rendering characteristics, and the rendering type can be expressed as an experience style; for example, the experience style can include "smooth", "exquisite", "low power consumption" and so on; corresponding For different rendering types, each mobile phone will generate the values of the parameters required for the rendering characteristics with the best rendering effect. For the same rendering type, the values of the parameters corresponding to different mobile phones may be different.

For example, for the rendering type of "smooth", the values of the parameters required for the rendering characteristics corresponding to mobile phone 1, mobile phone 2 and mobile phone 3 in FIG. 3 are all different.

In addition, during the testing process, the mobile phone can run other applications in the background to simulate the scene where the user actually uses the mobile phone; when the value of a certain parameter cannot be set on the mobile phone, the parameter can be marked as Invalid or unavailable.

After the test is completed, each mobile phone will send the optimal value of the parameters required for the rendering characteristics corresponding to each rendering type to the test server for storage by the test server.

In the test server, the corresponding relationship between the description information of the mobile phone, the identification of the application program, the rendering type, and the optimal value of the parameters required for rendering characteristics can be stored; wherein, the description information of the terminal includes the following information At least one: the model of the terminal and the hardware information of the terminal. The hardware information mainly includes hardware information related to rendering capabilities. For example, the hardware information may include information such as a central processing unit CPU, a graphics card, and memory.

It is understandable that since there are many types of terminals and the update speed is getting faster and faster, the rendering capabilities of different terminals may vary greatly; in order to better utilize the rendering capabilities of terminals with strong rendering capabilities, and to The terminal can complete the rendering well. The embodiment of the present application provides a rendering method. The rendering method is to obtain the values of the parameters of the appropriate rendering characteristics of a large number of terminals through pre-testing; when rendering is required, the terminal can send the server Request the value of the parameter that is most suitable for its own rendering characteristics, and then perform the rendering operation according to the value of the requested parameter, so as to obtain a better rendering effect.

It should be noted that, since in the embodiment of the present application, the terminal obtains the value of the parameter required for the rendering characteristic from the server, so when the terminal downloads the application program, it can first download the scene of the rendering characteristic that does not include the value of the parameter Description files and other relevant data of the application program; when the terminal installs or starts to start the application program, execute the method provided by the embodiment of the present application to obtain the values of the parameters required for rendering features from the server.

The rendering method provided by the embodiment of the present application will be specifically introduced below.

As shown in Figure 4, the present application provides an embodiment of a rendering method, which includes:

Based on the foregoing description, it can be seen that the terminal description information includes at least one of the following information: terminal model and terminal hardware information.

Wherein, the hardware information of the terminal may be a model of a central processing unit CPU, a model of a graphics processor, a size of a memory, and the like.

In addition, the description information of the terminal may also include the rendering frame rate used in the last rendering process of the terminal.

The embodiment of the present application does not specifically limit the type of description information of the first rendering characteristic. As an implementable manner, the description information of the first rendering characteristic may include the identifier of the first rendering characteristic and/or the description information of the first rendering characteristic ID of one or more parameters required.

In addition, the description information of the first rendering characteristic may also include other information, for details, please refer to related descriptions above.

As an implementable manner, the first request also carries the identifier of the target application program, and the rendering characteristics required by the target application program during running include the first rendering characteristic.

After step 101 is executed, correspondingly, the first server receives a first request from the terminal, where the first request carries description information of the terminal and description information of the first rendering characteristic.

In step 102, the first server obtains values of one or more parameters according to the description information of the terminal and the description information of the first rendering characteristic.

Wherein, the number of parameters obtained by the first server may be one or multiple; this parameter is a parameter required by the first rendering characteristic, and specifically may include one or more of the following parameters: the number of Gaussian blur iterations, Sampling times, sampling zoom range, high brightness ratio, and whether to enable high dynamic range (High Dynamic Range, HDR).

For example, as shown in Figure 5, when the terminal model is Mate10, the values of the parameters required for the first rendering feature are as follows: the number of Gaussian blur iterations is 4, the number of sampling times is 2, the sampling zoom range is 1, and the high The brightness ratio is 10% and HDR is not enabled; when the terminal model is Mate20, the values of the parameters required for the first rendering feature are as follows: the number of Gaussian blur iterations is 5, the number of samples is 3, and the sampling zoom range is 1. The proportion of high brightness is 10% and HDR is not enabled; when the terminal model is Mate30, the values of the parameters required for the first rendering feature are as follows: the number of Gaussian blur iterations is 6, the number of samples is 3, and the number of samples is 3. The zoom range is 2, the high brightness ratio is 20%, and HDR is not enabled; when the terminal model is Mate10, the values of the parameters required for the first rendering feature are as follows: the number of Gaussian blur iterations is 6, and the number of samples is 3. The sampling zoom range is 3, the high brightness ratio is 20%, and HDR is not enabled.

It should be noted that there are two cases where the first server obtains the value of the parameter. The first case is that the value of the parameter is stored in the first server, and the second case is that the value of the parameter is stored in other servers. (for example, the second server mentioned above, that is, the test server), which will be introduced respectively below.

For the first case, since an application may require multiple rendering features during runtime, step 102 may include:

According to the description information of the terminal, the description information of the first rendering characteristic, and the corresponding relationship among the description information of the terminal, the description information of the first rendering characteristic, and the value of the parameter, the first server obtains the information of one or more parameters. value.

Wherein, the corresponding relationship can be expressed in various ways, for example, the corresponding relationship can be represented by the following table.

Descriptive information of the terminal

Description of the first rendering feature

The value of the parameter

For the second case, since an application may require multiple rendering characteristics during runtime, and the values of parameters corresponding to different rendering characteristics can be stored in different second servers (ie, in the test server), the different first The second server controls the corresponding terminal to perform the test, and the specific test process can be understood by referring to the relevant description above.

Therefore, step 102 may include:

The first server determines a second server corresponding to the first rendering characteristic according to the description information of the first rendering characteristic;

The first server sends a request to the second server corresponding to the first rendering characteristic to obtain values of one or more parameters.

Wherein, the first server may store the corresponding relationship between the rendering characteristic and the second server in a form such as a table, so as to determine the server corresponding to the first rendering characteristic.

In this embodiment, the first server determines the second server corresponding to the first rendering characteristic according to the description information of the first rendering characteristic, and then the first server sends a request to the second server corresponding to the first rendering characteristic, and the second server After receiving the request, it will query according to the description information of the terminal, and then return the values of one or more parameters found in the query to the first server.

For example, the first rendering feature requires five parameters, the number of Gaussian blur iterations, the number of samples, the sampling zoom range, the ratio of high brightness, and whether to enable high dynamic range (High Dynamic Range, HDR). These five parameters are stored in the second server In A, the first rendering feature requires three parameters: the number of Gaussian blur iterations, the number of sampling times, and the sampling zoom range, and these three parameters are stored in the second server B; then the first server can determine the second server, and then send a request to the second server corresponding to the first rendering characteristic to obtain the values of the above five parameters; similarly, the first server can determine the second server corresponding to the second rendering characteristic, and then send the request to the second rendering characteristic The corresponding second server sends a request to obtain the values of the above three parameters.

Based on the relevant description of step 101, it can be seen that the description information of the terminal may also include the rendering frame rate used in the last rendering process of the terminal. Correspondingly, step 102 includes: the first server may also rate to get the value of one or more parameters.

In addition, based on the relevant description of step 101, it can be known that the request may also carry the identifier of the target application.

Correspondingly, the first server can obtain the values of one or more parameters required by the first rendering characteristic according to the application identifier, the description information of the terminal, and the description information of the first rendering characteristic, that is, the values required by the first rendering characteristic The value of one or more parameters of is obtained by the first server according to the identification of the application program, the description information of the terminal, and the description information of the first rendering characteristic; the specific process can be understood by referring to the foregoing description.

Step 103, the first server sends values of one or more parameters to the terminal.

Correspondingly, the terminal receives values of one or more parameters from the first server, that is, the values of the parameters are obtained by the first server according to the description information of the terminal and the description information of the first rendering characteristic.

After receiving the value of the parameter, the terminal may store the value of the parameter in the description file of the rendered scene, or in other files.

Step 104, the terminal executes a rendering operation corresponding to the first rendering characteristic according to values of one or more parameters.

Wherein, the rendering operation may be understood as an operation of rendering an image according to the method indicated by the first rendering characteristic.

It should be noted that there are many methods for implementing step 104, which are not specifically limited in this embodiment of the present application.

As an implementable manner, step 104 includes:

The terminal adjusts the value of one or more parameters required by the first rendering feature according to the current operating state of the terminal;

The terminal performs a rendering operation according to values of one or more parameters required by the adjusted first rendering characteristic.

The current operating state of the terminal can be expressed in various ways. As an achievable way, the current operating state of the terminal includes at least one of the following states: the state of the central processing unit CPU in the terminal, the state of the graphics processor in the terminal and the state of the memory in the terminal.

Wherein, the state of the CPU and the state of the graphics processor are generally represented by a usage rate (or utilization rate), and the state of the memory is generally represented by a remaining memory space.

In addition, the current operating status of the terminal may also include the occupancy rate of the storage read-write channel and the remaining bandwidth of the network card.

It should be noted that there are many ways to adjust the value of the parameter, and the adjustment can be made according to the current running state of the terminal.

For example, if the parameters required by the first rendering feature include the number of iterations of Gaussian blur and the number of samples, then when the CPU usage is high, the number of iterations of Gaussian blur and/or the number of samples can be appropriately reduced; When the usage rate is high, the number of Gaussian blur iterations and/or sampling times can be appropriately reduced, and when the remaining memory space is small, the number of Gaussian blur iterations and/or sampling times can be appropriately reduced.

In this embodiment of the present application, the terminal sends the first request to the first server, so that the first server obtains the parameters required by the first rendering characteristic according to the description information of the terminal carried in the first request and the description information of the first rendering characteristic. value; since the first server considers the description information of the terminal when determining the value of the parameter required for the first rendering characteristic, compared to dividing all terminal devices into several simple levels, the embodiment of the present application can The value of the parameter that is more suitable for the current terminal is selected, so that the terminal performs a rendering operation according to the value of the parameter, which can produce a better rendering effect.

Specifically, the embodiments of the present application can give full play to the rendering capabilities of high-configuration terminals, so that high-configuration terminals can obtain better rendering effects; especially when the scene to be rendered is complex, for example, when the scene to be rendered is complex In the case of 3D scenes, the embodiments of the present application can better utilize the advantages of high-configuration terminals in terms of rendering capabilities.

Moreover, the embodiments of the present application can prevent low-configuration terminals from using inappropriate parameter values for rendering, resulting in poor rendering effects and even unsmooth running of applications, so that applications with complex screen scenes can also be displayed on low-configuration terminals. run smoothly.

In order to illustrate that unsuitable parameter values will result in poor rendering effects, the embodiment of the present application adopts four sets of different parameter values for testing, and the rendering effect is shown in FIG. 6 .

As can be seen from Figure 6, when the number of Gaussian blur iterations is 6 and the number of sampling times is 1, the frame rate of the image is 60, and the rendering effect is better; and when the number of sampling times is increased to 6, the frame rate of the image drops to 37, and the rendering effect is poor; in theory, for high-configuration terminals, increasing the number of sampling times can improve the rendering effect, but the test results in this example are just the opposite. Therefore, only suitable parameter values can enable the terminal to obtain Better rendering effect.

Similarly, when the number of Gaussian blur iterations is 6, the number of sampling times is 6, the sampling zoom range is 4, and the high brightness ratio is 35%, the image frame rate is 31, and the rendering effect is better; while the values of the above parameters are the same On the basis of enabling HDR, the frame rate of the image will drop to 22, and the rendering effect will be poor; therefore, the appropriate parameter value can enable the terminal to obtain better rendering effect.

Based on the above description, it can be seen that in the embodiments of the present application, selecting appropriate parameter values for different terminals can improve the rendering effect of the terminal.

It should be noted that, in the embodiment of the present application, not only can the appropriate parameter values be selected for different terminals, but also different rendering types can be set for the same terminal, so that users can also experience the effects of different rendering types on the same terminal. The rendering effect; where, this rendering type can be understood as the experience style mentioned above.

The process of the user experiencing rendering effects of different rendering types will be described below with reference to FIG. 7 .

As shown in FIG. 7 , the present application provides another embodiment of a rendering method. In this embodiment, the rendering type includes a first rendering type and a second rendering type, and the first rendering type and the second rendering type refer to Different rendering types, different rendering types can be understood as different experience styles; based on this, this embodiment includes:

Step 201, the terminal receives first indication information from a user.

The first indication information indicates the first rendering type among multiple rendering types. The embodiment of the present application does not specifically limit the first rendering type, for example, it may be "smooth", "beautiful", "low power consumption" and so on.

Step 202, the terminal sends a first request to the first server.

The first request carries the description information of the terminal and the description information of the first rendering characteristic, and in addition, the first request also carries an identifier of the first rendering type.

In step 203, the first server obtains values of one or more parameters required by the first rendering type according to the identifier of the first rendering type, the description information of the terminal, and the description information of the first rendering characteristic.

In other words, the value of one or more parameters required by the first rendering type is obtained by the first server according to the identifier of the first rendering type, description information of the terminal, and description information of the first rendering characteristic.

Step 203 is similar to step 102, except that, in the process of executing step 203, the first rendering type selected by the user is also taken into consideration, other content can be understood by referring to the related description of step 102.

In step 204, the first server sends values of one or more parameters to the terminal.

Step 204 is similar to step 103, and step 204 can be understood by referring to the relevant description of step 103 for details.

Step 205, the terminal executes a rendering operation corresponding to the first rendering characteristic according to values of one or more parameters.

Step 205 is similar to step 104, and step 205 can be understood by referring to the relevant description of step 104 for details.

Step 206, the terminal receives second indication information from the user, where the second indication information indicates a second rendering type among the plurality of rendering types.

The embodiment of the present application does not specifically limit the second rendering type, for example, it may be "smooth", "beautiful", "low power consumption" and so on.

It should be noted that step 206 may be performed when steps 201 to 203 are performed, or may be performed under other conditions.

For example, the user does not select a rendering type at first, and in step 204, the first server sends the value of the parameter of the default rendering type; after that, the user selects the second rendering type, and then executes step 206, it can be seen that, in this In this case, steps 201 to 203 are not executed, but step 206 is executed.

Step 207, the terminal sends a second request to the first server, and the second request carries an identifier of the second rendering type.

It should be noted that after the terminal interacts with the first server (for example, steps 201 to 205 are executed), the first server already has the terminal's description information, so the second request may not carry the terminal's description information.

Since the first server can interact with multiple terminals, in order to identify which terminal it is, the second request may also carry terminal description information.

In addition, if the user selects only the second rendering type, but the type of the rendering characteristic remains unchanged, that is, the terminal still executes the rendering operation corresponding to the first rendering characteristic, then the second request may not carry the description information of the rendering characteristic.

If the user selects a rendering type for the second rendering characteristic (different from the first rendering characteristic) used in the subsequent rendering process, the second request may also carry description information of the second rendering characteristic.

Correspondingly, the first server receives the second request from the terminal, and the second request carries the identifier of the second rendering type; as an implementable manner, the second request carries the description information of the terminal and/or the second rendering characteristic Description.

In step 208, the first server obtains values of one or more parameters required by the second rendering type according to the identifier of the second rendering type.

As an implementable manner, step 208 includes: the first server obtains the information required by the second rendering type according to the identifier of the second rendering type and at least one of the description information of the terminal and the description information of the first rendering characteristic. The value of one or more parameters.

In step 209, the first server sends values of one or more parameters required by the second rendering type to the terminal.

Correspondingly, the terminal receives values of one or more parameters from the first server, where the values of the one or more parameters are obtained by the first server according to the identifier of the second rendering type,

Step 210, the terminal performs a rendering operation according to values of one or more parameters required by the second rendering type.

Wherein, the rendering operation may be a rendering operation corresponding to the first rendering characteristic, or may be a rendering operation corresponding to the second rendering characteristic.

Steps 206 to 210 are similar to steps 201 to 205. For details, reference may be made to the relevant descriptions of steps 201 to 205 to understand steps 206 to 210.

In this embodiment, the terminal first receives the first indication information, and then acquires the value of the parameters required by the first rendering type according to the first rendering type indicated by the first indication information, so as to provide the user with the rendering effect corresponding to the first rendering type ; Then, the terminal receives the second indication information, and then obtains the value of the parameter required by the second rendering type according to the second rendering type indicated by the second indication information, so as to provide the user with a rendering effect corresponding to the second rendering type, so as to realize different Switching of rendering effects.

It should be noted that, when step 210 is executed, if one of the parameters required by the first rendering type is the same as one of the parameters required by the second rendering type, in order to prevent the rendering effect from changing too much, you can first set The same parameter generates the value of the transition state, and then performs the rendering operation according to the value of the parameter of the transition state, so as to achieve a smooth transition between two different rendering types; among them, the method of generating the value of the parameter of the transition state is as follows Various, the embodiment of the present application does not specifically limit this, for example, the difference method can be used, and the transition can be calculated according to the values of the parameters required by the first rendering type and the values of the parameters required by the second rendering type The value of the parameter of the state.

For example, the parameters required by the first rendering type and the parameters required by the second rendering type both include the number of Gaussian blur iterations, and the number of Gaussian blur iterations required by the first rendering type is 4 times, and the number of Gaussian blur iterations required by the second rendering type If the number of Gaussian blur iterations is 6, you can first perform the rendering operation according to the Gaussian blur iteration number of 5 times, and then perform the rendering operation according to the Gaussian blur iteration number of 6 times, so as to achieve smoothing from the first rendering type to the second rendering type Switch to achieve smooth switching of different rendering effects.

In addition, it should be noted that the server can first send the values of the parameters required by each of the multiple rendering types to the terminal, and then the user selects the first rendering type among the multiple rendering types, and the terminal then After that, if the user selects the second rendering type among the multiple rendering types, the terminal will perform the rendering operation according to the value of the parameters required by the second rendering type; this method reduces the number of terminals and The interaction between the first server can reduce the switching time of different rendering types.
