[0091] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.

[0092] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0093] Currently, when implementing image rendering, one method is to use multiple rendering nodes to implement the complete rendering process. Due to the large number of rendering nodes, it is necessary to reasonably design the rendering process when using the Camera and setting the RT. Therefore, it is urgent to implement a low-complexity rendering process determination method for multiple rendering nodes.

[0094] In related technologies, there is an optional implementation method that creates a Camera for each Pass to specify the render texture (RT) obtained after rendering. It is necessary to create the required RT in advance, and then specify the corresponding RT for the input and output of each Pass.

[0095] In the above optional implementation, since each RT is bound to a Camera, RT management is very complex and repetitive and time-consuming. In addition, when it is necessary to add, delete, or adjust the order of rendering passes, all Camera-specified RTs must be modified to ensure correct results and optimal RT reuse.

[0096] For example, Figure 1As shown in the figure, it is a schematic diagram of a rendering process for alternating rendering through four rendering nodes. We need to specify the corresponding input RT and output RT for the Camera of each rendering node in advance. Figure 1 There are 4 rendering nodes in the image, identified as P1, P2, P3 and P4 respectively; each of these 4 rendering nodes is set with a Camera, the Camera identified as C1 for P1, the Camera identified as C2 for P2, the Camera identified as C3 for P3, and the Camera identified as C4 for P4; and the input RT and output RT corresponding to the Camera are formulated, where, Figure 1 As shown in (a), the output RT corresponding to C1 is RT1; Figure 1 As shown in (b), the input RT corresponding to C2 is RT1, and the output RT corresponding to C2 is RT2; Figure 1 As shown in (c), the input RT corresponding to C3 is RT2, and the output RT corresponding to C2 is RT1; Figure 1 As shown in (d), the input RT corresponding to C4 is RT1, and the output RT corresponding to C4 is RT2. Figure 1 The rendering process shown needs to specify RT for the Camera, and a Camera is created for each Pass. This makes the determination of the entire rendering process very complicated, and the complexity of modifying the rendering process is very high.

[0097] In order to solve the above problems, the present disclosure provides a rendering process determination method.

[0098] The at least two RTs to be used and the second association relationship between these rendering nodes and the at least two RTs can be directly determined based on the first association relationship between multiple rendering nodes. In this way, the rendering process can be determined based on the second association relationship. Compared with creating a Camera for each Pass and specifying an RT for each Camera, the RT is no longer bound to the Camera. Such a rendering process can be implemented through only one Camera, so the rendering process is simple. Moreover, since the RT is no longer bound to the Camera, there is no need to modify the binding relationship between the RT and the Camera after adding a Pass. The rendering process can be automatically determined only through the binding relationship between the updated multiple Passes, thereby simplifying the rendering process and reducing the complexity of modifying the rendering process.

[0099] The embodiments of the present disclosure provide a rendering process determination method, device, and electronic device, which can be implemented by a rendering process determination device or an electronic device, wherein the rendering process determination device can be a functional entity or functional module in the electronic device for implementing the rendering process determination method.

[0100] In the embodiment of the present disclosure, the electronic device may be a tablet computer, a mobile phone, a laptop computer, a PDA, a vehicle-mounted terminal, a wearable device, etc., and the embodiment of the present disclosure does not specifically limit this. Figure 2 FIG. 1 is a flow chart of a method for determining a rendering process, the method comprising:

[0101] 201. Obtain a first association relationship between multiple rendering nodes.

[0102] The first association relationship may be used to represent the association relationship between multiple rendering nodes.

[0103] In the embodiment of the present disclosure, the first association relationship mentioned above may represent a data transmission relationship between each rendering node and other rendering nodes among multiple rendering nodes. After obtaining the first association relationship of multiple rendering nodes, the flow direction of input data and output data between the multiple rendering nodes can be known.

[0104] For example, the association between render node A, render node B, and render node C may indicate that data output by render node A will be used as input data for render node B. Data output by render node B will be used as input data for render node C. In some embodiments, the first association between multiple render nodes may be obtained by obtaining a configuration file, which may include an input render node corresponding to each render node, and then obtaining the first association based on the configuration file.

[0105] In some embodiments, the first association relationship of the plurality of rendering nodes may be obtained by obtaining a configuration file, the configuration file including an input rendering node corresponding to each rendering node, drawing an association relationship graph based on the configuration file, and then obtaining the first association relationship according to the association relationship graph.

[0106] In an embodiment of the present invention, the above embodiment can be implemented through a rendering engine. After drawing the association relationship diagram, the association relationship diagram can also be displayed on an interface in the rendering engine to intuitively present the association relationship between each node.

[0107] Optionally, the above configuration file may further include an output rendering node for each rendering node.

[0108] For example, Figure 3 As shown, it is a schematic diagram of generating an association relationship diagram based on the content of a configuration file. Figure 3 In the example, there are four rendering nodes, which are represented as P1, P2, P3 and P4 respectively. Figure 3As shown in (a) of the figure, the configuration file shows that P1 is the initial rendering node. It has no input rendering node and the input is the initial image data. The input rendering node of P2 is P1, the initial input node of P3 is P2, and the initial input node of P4 is P3. Based on this, the association relationship diagram of the four rendering nodes can be obtained as follows: Figure 3 As shown in (b) in .

[0109] 202. Determine at least two RTs corresponding to the plurality of rendering nodes and a second association relationship according to the first association relationship.

[0110] 203. Determine a rendering process according to the second association relationship.

[0111] In the rendering process, the initial rendering node may or may not have an input RT.

[0112] The second association relationship is an association relationship between multiple rendering nodes and at least two RTs, that is, a data transmission relationship between the multiple rendering nodes and the at least two RTs. After obtaining the second association relationship between the multiple rendering nodes, the flow of input data and output data between the multiple rendering nodes and the at least two RTs can be known.

[0113] (1) In some embodiments, in the case where an initial rendering node has an input RT, the method for determining at least two RTs corresponding to multiple rendering nodes and the second association relationship based on the first association relationship is as follows: first, based on the first association relationship, an output RT is determined for each rendering node, and an input RT is determined for each rendering node to determine at least two RTs; finally, the second association relationship is determined based on the output RT and input RT of each rendering node.

[0114] (2) In some embodiments, in the case where the initial rendering node does not have an input RT, the method for determining at least two RTs corresponding to the multiple rendering nodes and the second association relationship based on the first association relationship is as follows: first, based on the first association relationship, an output RT is determined for each rendering node, and an input RT is determined for the rendering nodes other than the initial rendering node in the multiple rendering nodes to determine at least two RTs; then, based on the output RT of the initial rendering node and the input RT and output RT of the other rendering nodes, a second association relationship is determined.

[0115] In the above two types of embodiments (1) and (2), the method for determining the output RT for each rendering node according to the first association relationship may be: first, according to the first association relationship, determining whether there is an available RT for the first target rendering node in the created RTs, where the available RT refers to the RT in the created RTs that is not used as the input RT of the first target rendering node; if there is an available RT in the created RTs, then using the available RT as the output RT of the first target rendering node; if there is no available RT in the created RTs, then creating a new RT as the output RT of the first target rendering node;

[0116] The first target rendering node is any one of the plurality of rendering nodes. That is, the output RT can be determined for each of the plurality of rendering nodes by executing the method described above for the first target rendering node in the rendering order. In this way, the output RT of each of the plurality of rendering nodes can be determined.

[0117] Generally, since the input RT and output RT of a rendering node cannot be the same RT, that is, the number of RTs is at least 2, you can create two different RTs at the beginning for selection. Later, when determining the output RT for multiple rendering nodes, you can consider adding the newly created RT or not according to the actual situation.

[0118] The above method of determining the output RT uses a greedy algorithm to select the output RT of the current rendering node from the created RTs. If there is an available RT among the created RTs, an available RT is directly used as the output RT of the current rendering node. If there is no available RT among the created RTs, it means that the number of currently created RTs cannot meet the demand, and a new RT needs to be created as the output RT.

[0119] In some embodiments, the RT size configured for each rendering node can be obtained, and then an output RT can be determined for each rendering node based on the first association relationship. Specifically, based on the first association relationship, a first RT whose size is greater than or equal to the RT size can be determined as the output RT for each rendering node. In other words, when selecting an output RT, the output RT size must meet certain RT size requirements. The RT size can refer to the number of pixels corresponding to the rendered texture. This method of selecting an output RT ensures that an output RT that meets the RT size requirements is selected for each rendering node.

[0120] In the embodiment corresponding to (1) above, the method for determining the input RT for each rendering node according to the first association relationship may be: if the first target rendering node is determined to be the initial rendering node according to the first association relationship, the designated RT is determined to be the input RT of the first target rendering node; if the first target rendering node is determined to be another rendering node according to the first association relationship, the output RT of the rendering node one level above the first target rendering node is determined to be the input RT of the first target rendering node.

[0121] For example, assuming that the created RTs include RT1 and RT2, where RT1 is the designated RT of the initial input, if the initial rendering node has an input RT, the following is followed: Figure 3 When determining RT in the node graph shown in (b): the input RT of P1 can be the specified RT1. When selecting the output RT for P1, if it is determined that there is an available RT2 in the created RT, then RT2 can be used as the output RT of P1. This RT2 is also the input RT of P2. When selecting the output RT for RT2, if it is determined that there is an available RT1 in the created RT, then RT1 can be used as the input RT of P2. This RT1 is also the input RT of P3. When selecting the output RT for P3, if it is determined that there is an available RT2 in the created RT, then RT2 can be used as the output RT of P3. This RT2 is also the input RT of P4. When selecting the output RT for P4, if it is determined that there is an available RT1 in the created RT, then RT1 can be used as the output RT of P4. The second association relationship finally determined in this example is as follows: Figure 4 As shown, Figure 4 The dotted arrows in the middle indicate the association relationship between the four rendering nodes, and the solid arrows indicate the second association relationship.

[0122] In the embodiment corresponding to (2) above, determining the input RT for the other rendering nodes according to the first association relationship includes: if the first target rendering node is determined to be the other rendering node according to the first association relationship, determining the output RT of the upper-level rendering node of the first target rendering node as the input RT of the first target rendering node;

[0123] Further, if the first target rendering node is determined to be the initial rendering node according to the first association relationship, no input RT is determined for the first target rendering node.

[0124] For example, assuming that the created RTs include RT1 and RT2, and there is no designated RT for initial input, in the case where the initial rendering node does not have an input RT, the following is followed: Figure 3When selecting RT in the node graph shown in (b): P1 has no input RT. When selecting output RT for P1, it is determined that there are available RT1 and RT2 in the created RT. Then, any RT can be selected from RT1 and RT2 as the output RT of P1. Assuming that RT2 is selected as the output RT, and RT2 is also the input RT of P2, when selecting output RT for RT2, it is determined that there is available RT1 in the created RT. Then, RT1 can be used as the input RT of P2. This RT1 is also the input RT of P3. When selecting output RT for P3, it is determined that there is available RT2 in the created RT. Then, RT2 can be used as the output RT of P3. This RT2 is also the input RT of P4. When selecting output RT for P4, it is determined that there is available RT1 in the created RT. Then, RT1 can be used as the output RT of P4. The second association relationship finally determined in this example is as follows: Figure 5 shown. Figure 5 The dotted arrows in the middle indicate the association relationship between the four rendering nodes, and the solid arrows indicate the second association relationship.

[0125] During the actual rendering process, the output of the last rendering node must be guaranteed to be the final RT (i.e., outputRT). This RT is usually the RT to be displayed, so this RT is generally specified. Therefore, after obtaining the number of RTs of multiple rendering nodes and the second association relationship according to the greedy algorithm above, it is also necessary to determine whether the output RT of the last rendering node is outputRT. If not, it is exchanged with the output RTs of all rendering nodes whose outputs are outputRT.

[0126] That is, in some embodiments, determining the second association relationship based on the first association relationship may include: first determining a target association relationship between the plurality of rendering nodes and at least two RTs based on the first association relationship; then, if the output RT of the last rendering node in the target association relationship is not the final RT, swapping the output RT of the last rendering node with the output RT of a second target rendering node to update the target association relationship to a second association relationship, wherein the second target rendering node is a rendering node other than the last rendering node in the plurality of rendering nodes whose input RT is the final RT; and if the output RT of the last rendering node in the target association relationship is the final RT, setting the target association relationship as the second association relationship.

[0127] For example, it is assumed that the association relationship between the multiple rendering nodes and at least two RTs obtained at the beginning of the greedy algorithm is as follows: Figure 5 As shown in, but Figure 5The output RT of the last rendering node P4 is RT1, which is not the final RT. RT2 is the final RT. Then RT1 and RT2 can be swapped, so that the association relationship obtained at the beginning can be updated, and the result is as follows: Figure 6 The solid arrows indicate the relationship.

[0128] The method for determining the rendering process provided in the embodiment of the present disclosure is implemented by the RT manager of the rendering engine. For example, all RT creation processes can be handed over to the RT manager, and the RT manager creates RT and determines the corresponding input RT and output RT for each rendering node based on the connection status of the nodes. In this way, it is possible to automatically generate an RT manager including at least two RTs according to the node graph (that is, the first association relationship), and then implement the entire rendering process based on the RT manager. With this set of RT managers including at least two RTs, there is no need to manually set the input and output RT for each node. Moreover, there is no need to know whether the output RT of a certain Pass is RT1 or RT2, you only need to care about the association relationship between multiple Passes. This greatly simplifies the process of determining the rendering process.

[0129] The rendering process determination method provided by the embodiments of the present disclosure can directly determine at least two RTs to be used, and the second association relationship between these rendering nodes and the at least two RTs, based on the first association relationship between multiple rendering nodes. In this way, the rendering process can be determined based on the second association relationship. Compared with the method of creating a Camera for each Pass and specifying an RT for each Camera, the RT is no longer bound to the Camera. Such a rendering process can be implemented using only one Camera, so the rendering process is simple. Moreover, since the RT is no longer bound to the Camera, there is no need to modify the binding relationship between the RT and the Camera after adding a Pass. The rendering process can be automatically determined based on the updated binding relationship between the multiple Passes, thereby simplifying the rendering process and reducing the complexity of modifying the rendering process.
