Description

Technical Field

[0001] The present disclosure relates to the field of computer technology, and in particular to a rendering display method, device, computer equipment and storage medium. Background Art

[0002] In application scenarios such as games, there is a demand for scene construction, such as the demand for game scene construction. Since scenes are generally large, they are usually divided into multiple terrain areas based on the preset size of the scene. After the terrain and other aspects of each terrain area are designed, the multiple terrain areas are spliced ​​to obtain the final scene for rendering and display. After designing each terrain area separately, since adjacent terrain areas may have differences in terrain, after the terrain areas are spliced, the resulting splicing may result in unnatural terrain transitions, resulting in poor rendering and display effects.

[0033] In order to make the purpose, technical scheme and advantages of the embodiments of the present disclosure clearer, the technical scheme in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. The components of the embodiments of the present disclosure generally described and shown here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present disclosure is not intended to limit the scope of the present disclosure claimed for protection, but merely represents the selected embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present disclosure.

[0034] According to research, when constructing a scene, since the size of the scene is generally large, the scene is divided into multiple terrain areas, and the scene is obtained by splicing the terrain of multiple terrain areas. For multiple terrain areas in the scene, the coupling between adjacent terrain areas is high. For example, when setting the river terrain on two adjacent terrain areas, if the flow direction of the river is set in one terrain area, the corresponding river flow direction should also be set in the other terrain area, so that the river displayed on the two terrain areas is logical. However, when designing multiple terrain areas, each terrain area is usually designed separately. In this way, the designed terrain area may have deviations in expressing the terrain. For example, the same river displayed has different river flow directions in two adjacent terrain areas. After splicing the terrain areas, the splicing result may have unnatural terrain transitions, resulting in poor rendering and display effects.

[0035] Based on the above research, the present disclosure provides a rendering and display method. After determining the terrain data of the target terrain area, the terrain attribute information corresponding to each sub-terrain area constituting the target terrain area is determined. Such terrain attribute information can form terrain constraints on the sub-terrain areas. The terrain patch data generated for the sub-terrain areas using the terrain attribute information can reflect the terrain features that should exist in the sub-terrain areas in the terrain data. Therefore, after the sub-terrain areas are spliced, terrain patch data that is separated from the terrain data will not appear on the terrain. When the terrain data is determined, it is easier to design a regular terrain transition. Therefore, the target terrain area rendered and displayed by the target terrain patch data can make the terrain transition more natural, thereby making the rendering and display effect better.

[0036] The defects existing in the above solutions are the results obtained by the inventor after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present disclosure for the above problems below should be the contributions made by the inventor to the present disclosure during the disclosure process.

[0037] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0038] To facilitate understanding of the present embodiment, a rendering display method disclosed in the embodiment of the present disclosure is first introduced in detail. The execution subject of the rendering display method provided in the embodiment of the present disclosure is generally a computer device with certain computing capabilities, and the computer device includes, for example: a terminal device or a server or other processing device, and the terminal device can be a user equipment (User Equipment, UE), a mobile device, a user terminal, a terminal, a cellular phone, a cordless phone, a personal digital assistant (Personal Digital Assistant, PDA), a handheld device, a computing device, a vehicle-mounted device, a wearable device, etc. In some possible implementations, the rendering display method can be implemented by a processor calling a computer-readable instruction stored in a memory.

[0039] The rendering and display method provided by the embodiment of the present disclosure is described below.

[0040] The method for splicing terrain areas provided in the embodiments of the present disclosure can be applied to scenes such as the game field, animation film and television production, for example, in the game field, it is applied to the production of game scenes, or in the animation film and television production scene, it is applied to the production of animation scenes. In a specific implementation, the game scene or the animation scene is used as the target terrain area described in the embodiments of the present disclosure. Since the target terrain area is generally large, for example, the design size is 10 kilometers × 10 kilometers.

[0041] Before designing the terrain of the sub-terrain area, the terrain data of the target terrain area as a whole can be determined first, so that the terrain distribution of the target terrain area as a whole can be determined macroscopically. After determining the overall terrain distribution of the target terrain area, the sub-terrain area can be constrained in the terrain. Such constraints can control that when the terrain design of the sub-terrain area is carried out, it will not affect the overall terrain design of the target terrain area, such as the flow direction of rivers, the direction of mountains, etc. In this way, after the constrained terrain design of the sub-terrain area, the corresponding terrain patch data can be used to obtain the target terrain patch data of the target terrain area as a whole, so as to render the target terrain area. Since the obtained target terrain area conforms to the terrain transition law, the authenticity of the obtained target terrain area will also be higher.

[0042] See also Figure 1 FIG. 1 is a flowchart of a rendering and display method provided by an embodiment of the present disclosure, wherein the method includes steps S101 to S104, wherein:

[0043] S101: determining terrain attribute information corresponding to each sub-terrain area in the target terrain area based on terrain data determined for the target terrain area;

[0044] S102: for any sub-terrain area, generating terrain patch data for the sub-terrain area based on terrain attribute information corresponding to the sub-terrain area;

[0045] S103: Based on the positions of the sub-terrain areas in the target terrain area, the terrain patch data corresponding to the sub-terrain areas are used to perform splicing processing on the sub-terrain areas, and the terrain patch data corresponding to the sub-terrain areas are updated based on the obtained splicing processing results;

[0046] S104: Determine target terrain patch data of the target terrain area based on the updated terrain patch data corresponding to each sub-terrain area, and render and display the target terrain area based on the target terrain patch data.

[0047] The above-mentioned S101 to S104 are described in detail below.

[0048] With respect to the above S101, the target terrain area is first described. In different application scenarios, the determined target terrain area may be different, which can be specifically reflected in the different size design requirements for the target terrain area. In one possible case, in the field of games, a larger game scene is usually required, and the target terrain area can be set to be designed as a scene with a larger size, such as setting the design size to 10 km × 10 km as described above.

[0049] When the target terrain area is determined, the terrain data of the target terrain area can also be obtained according to the terrain design requirements of the target terrain area. In a possible case, the terrain data described herein may specifically include a low-precision terrain area of ​​the target terrain area. Specifically, the low-precision terrain area is a terrain area with a lower precision that is proportionally reduced in design size from the target terrain area, and the overall terrain design of the target terrain area can be performed on the low-precision terrain area. Since the size of the low-precision terrain area is small, it is easy to perform the overall terrain design, and for the low-precision terrain area, only the terrain design of the target terrain area needs to be undertaken, and there is no need for rendering and display, so a higher design precision is not required, which can save computing resources.

[0050] For example, if the terrain design requirements of the target terrain area include designing a river running from north to south, when determining the low-precision terrain area, refer to Figure 2 As shown, it is a schematic diagram of terrain data provided by an embodiment of the present disclosure. In the schematic diagram, the design size of the low-precision terrain area is specifically included, for example, 0.1 km × 0.1 km. The designed terrain specifically includes a river with a varying river width, and the direction of the river is determined to be from north to south.

[0051] After obtaining the terrain data of the target terrain area, the terrain attribute information of each sub-terrain area contained in the target terrain area can be determined using the terrain data of the target terrain area. Here, the sub-terrain areas in the target terrain area are first described. Since the design size of the target terrain area is usually large, in order to reduce the workload during the design and improve the design efficiency of the target terrain area when performing terrain design on the target terrain area, the target terrain area will be divided into multiple sub-terrain areas of smaller sizes, such as dividing the target terrain area into sub-terrain areas of 10 meters × 10 meters. Here, the size of the division is not limited, and the division method is not limited. After the sub-terrain areas of smaller sizes are obtained by division, the sub-terrain areas can be assigned to different designers for synchronous design, which can improve the overall design efficiency of the target terrain area.

[0052] For the terrain data obtained above, since the terrain data can reflect the overall design of the target terrain area, for each sub-terrain area divided from the target terrain area, the terrain attribute information of the sub-terrain area can be determined according to the position of the sub-terrain area in the target terrain area. Here, the terrain attribute information of the sub-terrain area specifically includes information indicating the target object to be deployed in each sub-terrain area, and the deployment position of the target object in the sub-terrain area.

[0053] For example, see Figure 3 FIG. 1 is a schematic diagram of determining terrain attribute information of a sub-terrain area provided by an embodiment of the present disclosure. Figure 3 In (a), a schematic diagram of the target terrain area is shown, and the specific design size is 10 km × 10 km. In order to simplify the description, the target terrain area is divided into 3 × 3 sub-terrain areas. Figure 2 The terrain data in can also be divided similarly, according to the terrain data at the corresponding position, Figure 3 The corresponding terrain attribute information is determined by dividing the sub-terrain areas. Figure 3 Take the sub-terrain area in the middle of the target terrain area shown in (a) as an example, that is, Figure 3 The sub-terrain area designed in (b) is based on Figure 2 The terrain data of the corresponding position in the sub-terrain area can determine a section of the river in the sub-terrain area, and can determine the inflow position and outflow position of the river in the section on the sub-terrain area, as well as the direction of the river, that is, the deployment position of the river in this section in the sub-terrain area.

[0054] In addition, for the sub-terrain area, in addition to some objects determined by the constraints of the terrain data, such as the river described above, other objects can be added, such as sand or grass designed beside the river, to further refine and enrich the sub-terrain area. For other sub-terrain areas in the target terrain area, the corresponding terrain attribute information can also be determined in a similar manner, and the details will not be repeated here.

[0055] With respect to the above S102, when the terrain attribute information corresponding to the sub-terrain area is determined, for any sub-terrain area, terrain tile data may be generated for the sub-terrain area based on the terrain attribute information corresponding to the sub-terrain area.

[0056] In a specific implementation, terrain patch data can be generated for a sub-terrain area in the following manner: based on object patch data corresponding to at least one target object to be deployed in the sub-terrain area, and the deployment position corresponding to the at least one target object in the sub-terrain area, terrain patch data is generated for the sub-terrain area.

[0057] Here, the target objects to be deployed may include, for example, the rivers, sandstones, grass, etc. designed on the sub-terrain area as described above. For these target objects, for example, corresponding patch data may be predetermined. When generating terrain patch data for the sub-terrain area, by calling the corresponding patch data and according to the corresponding deployment position of the target object in the sub-terrain area, terrain patch data may be generated for the sub-terrain area more efficiently. In this way, the efficiency of rendering and display may be correspondingly improved.

[0058] With respect to the above S103, when the terrain patch data corresponding to each sub-terrain area in the target terrain area are determined, each sub-terrain area can be spliced ​​according to its position in the target terrain area, and the terrain patch data corresponding to each sub-terrain area can be updated based on the obtained splicing result.

[0059] In a specific implementation, when performing stitching processing on each sub-terrain area, the following method can be specifically adopted: based on the positions of each sub-terrain area in the target terrain area, a plurality of positions to be stitched corresponding to each sub-terrain area are determined; according to a preset stitching order, a current position to be stitched is selected from the plurality of positions to be stitched, and a stitching processing is performed on the first sub-terrain area and the second sub-terrain area associated with the current position to be stitched to obtain the stitching processing result.

[0060] Specifically, since each sub-terrain region exists independently but is part of the target terrain region, the sub-terrain regions can be spliced ​​into the target terrain region according to the position of each sub-terrain region in the target terrain region. In a possible case, the sub-terrain region is a rectangle, and when splicing, the sub-terrain region and other sub-terrain regions adjacent to each other in the target terrain region are spliced ​​through adjacent rectangular boundaries. Here, in the two sub-terrain regions to be spliced, the adjacent boundaries include the position to be spliced.

[0061] For example, see Figure 4 FIG. 1 is a schematic diagram of splicing sub-terrain areas provided by an embodiment of the present disclosure. Figure 4 Specifically, Figure 3 The target terrain area in (a) is divided into multiple sub-terrain areas. There is a position to be spliced ​​between two adjacent sub-terrain areas. Figure 4 Some of the positions to be spliced ​​are marked in FIG. For each sub-topographic region, the corresponding position to be spliced ​​when splicing with other sub-topographic regions can also be determined accordingly.

[0062] When multiple positions to be spliced ​​are determined, the sub-terrain areas can be spliced. In one possible case, since the amount of terrain patch data of the sub-terrain area is large, if all sub-terrain areas of the target terrain area are spliced ​​at the same time, the amount of data to be processed is also large, and the computing power of the computer device may not be able to bear it. Therefore, when splicing the sub-terrain areas, the number of sub-terrain areas that can be spliced ​​in one splicing processing cycle can be determined according to the computing power of the computer device, and then some of the positions to be spliced ​​are selected from the multiple positions to be spliced ​​as the current positions to be spliced. Alternatively, the current positions to be spliced ​​can be selected one by one according to a preset splicing order. For example, if the preset splicing order is to splice the horizontal positions to be spliced ​​first and then the vertical positions to be spliced, then the first sub-terrain area and the second sub-terrain area associated with the horizontal positions to be spliced ​​are spliced ​​in turn. After all the horizontal positions to be spliced ​​are spliced, the vertical positions to be spliced ​​are spliced.

[0063] After selecting the current position to be spliced, the first sub-terrain area and the second sub-terrain area associated with the current position to be spliced ​​can be spliced ​​to obtain a splicing result. Specifically, since the splicing of the sub-terrain areas specifically involves splicing the boundaries of the sub-terrain areas, when performing the splicing, based on the current position to be spliced, a first splicing boundary can be determined in the first sub-terrain area, and a second splicing boundary can be determined in the second sub-terrain area, and then based on the first splicing boundary and the second splicing boundary, the first sub-terrain area and the second sub-terrain area are spliced ​​to obtain the splicing result.

[0064] Here, since there is terrain attribute information corresponding to the sub-terrain area, the deployment position of the target object in the sub-terrain area in the target terrain area can be determined, such as the inflow position, outflow position, direction of the river, etc. For the target terrain area, there is continuity between the sub-terrain areas containing the same object. For example, the river in the target terrain area has no breaks in the multiple covered sub-terrain areas, the riverbed is continuous, and the direction is consistent. Therefore, when splicing two adjacent sub-terrain areas, it is necessary to determine the two corresponding splicing boundaries when the two sub-terrain areas are spliced. Using the current position to be spliced, the first splicing boundary is determined for the associated first sub-terrain area, and the second splicing boundary is determined for the associated second sub-terrain area, so that there will be no violation of geographical rules after splicing.

[0065] For example, see Figure 5 FIG. 1 is another schematic diagram of splicing sub-terrain areas provided by an embodiment of the present disclosure, which also includes Figure 4 Part of the sub-terrain area shown in Figure 5 , a position to be spliced ​​is specifically shown, and two sub-topographic regions associated with the position to be spliced ​​include a first sub-topographic region labeled 2 and a second sub-topographic region labeled 5. For the position to be spliced, a first splicing boundary a1 in the first sub-region and a second splicing boundary a2 in the second sub-region can be determined. The first splicing boundary a1 and the second splicing boundary a2 can be used to correctly splice the first sub-region and the second sub-region. For example, Figure 5 If the splicing boundary corresponding to the sub-region associated with the position to be spliced ​​is not determined, the following may occur: Figure 5 In the situation shown in (b), that is, the stitching boundary a1 of the first sub-area is stitched with the stitching boundary b of the second sub-area, then in the target terrain area, the direction of the river in the sub-terrain area labeled 5 changes in violation of geographical rules and a break occurs, that is, a stitching error occurs in the sub-terrain area.

[0066] With respect to the above S104, after updating the terrain patch data corresponding to each sub-terrain area based on the obtained stitching processing result, the target terrain patch data of the target terrain area can be determined by using the updated terrain patch data corresponding to each sub-terrain area, and the target terrain area can be rendered and displayed based on the target terrain patch data.

[0067] Here, since the accuracy of the splicing can be guaranteed when the sub-terrain areas are spliced, the target terrain patch data obtained by the splicing result can also ensure that the target object is logical when displayed, thereby improving the authenticity of the target terrain area after rendering and display.

[0068] In another embodiment of the present disclosure, a specific method for re-rendering and displaying the target terrain area after the terrain data is modified is also provided. In a specific implementation, before determining the target terrain patch data of the target terrain area based on the terrain patch data corresponding to each sub-terrain area after the update, in response to the modification operation on the terrain data, a first target sub-terrain area associated with the modification operation can be determined from each sub-terrain area, and the terrain attribute information corresponding to the first target sub-terrain area can be updated; based on the position of the first target sub-terrain area in the target terrain area and the terrain patch data generated based on the updated terrain attribute information of the first target sub-terrain area, the first target sub-terrain area and the sub-terrain areas adjacent to the position of the first target sub-terrain area in each sub-terrain area are spliced, and the terrain patch data corresponding to the first target sub-terrain area and other associated sub-terrain areas are updated.

[0069] For example, see Figure 6FIG. 1 is a schematic diagram of another type of terrain data provided by an embodiment of the present disclosure. Figure 2 In the terrain data shown in FIG. 2 , the riverbed shape of the river is modified at the dotted box labeled 2, and the original straight line shape is modified to a curved shape. In this modification operation, the dotted box labeled 2 is specifically modified, so the first target sub-terrain area associated with the modification operation is the corresponding sub-terrain area at this location. Since the riverbed shape is modified, the terrain attribute information of the first target sub-terrain area can be updated.

[0070] After obtaining the updated terrain attribute information of the first target sub-terrain area, the terrain patch data of the first target sub-terrain area can also be generated. The specific method can refer to the above corresponding description, which will not be repeated here. After determining the terrain patch data of the first target sub-terrain area, the sub-terrain area adjacent to the position of the first target sub-terrain area can be determined from each sub-terrain area, and the splicing process is re-performed to update the terrain patch data of these sub-terrain areas, and re-determine the target terrain patch data of the target terrain area.

[0071] In this way, when only a small range of modifications are made to the terrain data, a small number of first target sub-terrain areas that need to re-update the terrain patch data can be determined based on the modification operation, and the splicing process can be re-performed without re-splicing all sub-terrain areas under the target terrain area. This requires less computing power and is more efficient.

[0072] In another embodiment of the present disclosure, a specific method for re-rendering and displaying the target terrain area after the target terrain area is expanded is also provided. In a possible case, if there is a need to expand the target terrain area after the target terrain area is rendered and displayed, the target terrain area can be further expanded in units of sub-terrain areas based on the current target terrain area.

[0073] In a specific implementation, in response to an expansion operation on the target terrain area, a sub-terrain area to be expanded corresponding to the expansion operation can be determined, and a second target sub-terrain area adjacent to the sub-terrain area to be expanded can be determined from the sub-terrain areas; based on the target terrain attribute information determined for the sub-terrain area to be expanded, target terrain patch data of the sub-terrain area to be expanded is generated; using the target terrain patch data and the terrain patch data corresponding to the second target sub-terrain area, the sub-terrain area to be expanded and spliced ​​are expanded and spliced ​​on the second target sub-terrain area, and the target terrain patch data is updated based on the obtained expansion and splicing processing result; based on the updated target terrain patch data, the target terrain area after the expansion operation is rendered and displayed.

[0074] In a possible case, a sub-terrain area can be expanded at the outer edge of the target terrain area. After determining the sub-terrain area to be expanded, target terrain attribute information can also be similarly determined for the sub-terrain area to be expanded, thereby determining the corresponding target terrain patch data. When determining the target terrain attribute information of the sub-terrain area to be expanded, a second target sub-terrain area adjacent to the sub-terrain area to be expanded can be first determined, and then the target terrain attribute information of the sub-terrain area to be expanded can be determined based on the terrain attribute information of the second target sub-terrain area.

[0075] For example, see Figure 7 FIG. 1 is a schematic diagram of a sub-terrain area to be expanded provided by an embodiment of the present disclosure. The sub-terrain area to be expanded can determine a sub-terrain area adjacent to the target terrain area, that is, the second target sub-terrain area numbered 2. According to the terrain attribute information of the second target sub-terrain area, the target terrain attribute information of the sub-terrain area to be expanded can be constrained, for example, Figure 7 In the process, the direction of the river at the upstream position and the position of the riverbed of the second target sub-terrain area are determined in a coherent manner in the sub-terrain area to be expanded. In this way, even if the target terrain area currently displayed by rendering is expanded, the displayed target object will not lack display logic, and the authenticity of the expanded target terrain area is guaranteed.

[0076] After determining the target terrain attribute information of the sub-terrain area to be expanded, the corresponding target terrain patch data can be determined, and the sub-terrain area to be expanded and the second target sub-terrain area can be spliced ​​using the terrain patch data of the second target sub-terrain area, and the target terrain patch data of the target terrain area can be updated, so as to render and display the expanded target terrain area using the updated target terrain patch data.

[0077] In this way, when the target terrain area is expanded, there is no need to re-determine the terrain data of the target terrain area and then reuse the terrain data to render and display the target terrain area, which makes the operation simpler and more efficient.

[0078] Those skilled in the art will appreciate that, in the above method of specific implementation, the order in which the steps are written does not imply a strict execution order and does not constitute any limitation on the implementation process. The specific execution order of the steps should be determined by their functions and possible internal logic.
