Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are only some embodiments of the present disclosure, but not all embodiments. The components of the disclosed embodiments generally described and illustrated herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present disclosure is not intended to limit the scope of the disclosure, as claimed, but is merely representative of selected embodiments of the disclosure. All other embodiments, which can be made by those skilled in the art based on the embodiments of this disclosure without making any inventive effort, are intended to be within the scope of this disclosure.
It is found that when constructing a scene, the size of the scene is generally large, so that the scene is divided into a plurality of terrain areas, and the terrain areas are spliced to obtain the scene. For a plurality of terrain areas in a scene, the coupling between adjacent terrain areas is high, for example, when river terrains are arranged on two adjacent terrain areas, if the flow direction of a river is arranged in one terrain area, the corresponding flow direction of the river is also arranged on the other terrain area, so that the river displayed on the two terrain areas is in accordance with logic. However, when designing a plurality of terrain areas, each terrain area is usually designed separately, so that the designed terrain areas may have deviation when expressing the terrain, for example, the same river is shown to have different river directions in two adjacent terrain areas, and thus after the terrain areas are spliced, the obtained splicing result may appear that the terrain transition is unnatural, and further, the rendering display effect is poor.
Based on the above-mentioned study, the present disclosure provides a rendering display method, after determining the terrain data of a target terrain area, determining the terrain attribute information corresponding to each sub-terrain area forming the target terrain area, where such terrain attribute information may form a terrain constraint on the sub-terrain area, and using the terrain patch data generated by the terrain attribute information for the sub-terrain area may reflect the terrain feature that should be present in the terrain data under the sub-terrain area, so after performing the stitching processing on the sub-terrain area, the terrain patch data that is separated from the terrain data does not appear on the terrain, and the terrain data may be relatively easily designed regularly on the terrain transition during the determination, so that the obtained target terrain patch data renders the displayed target terrain area, and may make the terrain transition more natural, and further make the rendering display effect better.
The defects of the scheme are all results obtained by the inventor after practice and careful study, and therefore, the discovery process of the above problems and the solutions to the above problems set forth hereinafter by the present disclosure should be all contributions of the inventors to the present disclosure during the course of the present disclosure.
It should be noted that like reference numerals and letters refer to like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures.
For the sake of understanding the present embodiment, first, a detailed description will be given of a rendering display method disclosed in the present embodiment, where an execution subject of the rendering display method provided in the present embodiment is generally a computer device with a certain computing capability, and the computer device includes, for example, a terminal device or a server or other processing device, and the terminal device may be a User Equipment (UE), a mobile device, a User terminal, a cellular phone, a cordless phone, a Personal digital assistant (Personal DIGITAL ASSISTANT, PDA), a handheld device, a computing device, an in-vehicle device, a wearable device, or the like. In some possible implementations, the rendering display method may be implemented by a processor invoking computer readable instructions stored in a memory.
The rendering display method provided by the embodiment of the present disclosure is described below.
The terrain area splicing method provided by the embodiment of the disclosure can be applied to scenes such as game fields and cartoon video production, for example, the method can be applied to the production of game scenes in the game fields or the cartoon scenes in the cartoon video production scenes. In a specific implementation, a game scene, a cartoon scene, or the like is taken as the target terrain area described in the embodiments of the present disclosure. Since the target terrain area is typically large, for example, 10 km by 10 km in design size.
The overall terrain data for the target terrain area may be determined prior to terrain planning for the sub-terrain area, such that the overall terrain distribution for the target terrain area may be determined macroscopically. After determining the global terrain distribution of the target terrain area, the sub-terrain areas therein may be subjected to terrain constraints, which may control the terrain design of the sub-terrain areas without affecting the global terrain design of the target terrain area, such as the flow direction of a river, the mountain strike, etc. Thus, after the constraint terrain design is carried out on the sub-terrain area, the corresponding terrain patch data is utilized to obtain the overall target terrain patch data of the target terrain area, so that the target terrain area is rendered. The obtained target terrain area accords with the terrain transition rule, so that the authenticity of the obtained target terrain area is higher.
Referring to fig. 1, a flowchart of a rendering display method according to an embodiment of the disclosure is shown, where the method includes steps S101 to S104, where:
S101, determining terrain attribute information corresponding to each sub-terrain area in a target terrain area based on terrain data determined for the target terrain area;
S102, generating terrain patch data for any sub-terrain area based on terrain attribute information corresponding to the sub-terrain area;
s103, based on the positions of the sub-terrain areas in the target terrain areas, respectively, performing splicing processing on the sub-terrain areas by utilizing the terrain patch data corresponding to the sub-terrain areas, and updating the terrain patch data corresponding to the sub-terrain areas based on the obtained splicing processing result;
And S104, determining target terrain patch data of the target terrain area based on the updated terrain patch data corresponding to each sub-terrain area, and rendering and displaying the target terrain area based on the target terrain patch data.
The following describes the steps S101 to S104 in detail.
With regard to S101, a target topographic region will be described first. In different application scenarios, the determined target terrain areas may be different, and may be specifically represented by different size design requirements for the target terrain areas. In one possible scenario, where a larger game scene is typically required in the gaming field, the corresponding settable target terrain area is designed as a scene having a larger size, such as the design size set to 10 km x 10 km described above.
Under the condition of determining the target terrain area, the terrain data of the target terrain area can be acquired according to the terrain design requirement of the target terrain area. In one possible scenario, the terrain data described herein may include, in particular, low-precision terrain areas of the target terrain area. Specifically, the low-precision terrain area is a terrain area with lower precision that is scaled down equally on the target terrain area in the design dimension, and the overall terrain design for the target terrain area can be made on the low-precision terrain area. Because the size of the low-precision terrain area is smaller, the overall terrain design is easy to carry out, and for the low-precision terrain area, only the terrain design of the target terrain area is needed to be born, and the rendering display requirement is not needed, so that the high design precision is not needed, and the calculation resource can be saved.
For example, if the terrain design requirement of the target terrain area includes designing a river that runs through from north to south, when determining the low-precision terrain area, referring to fig. 2, a schematic diagram of terrain data is provided for an embodiment of the disclosure, where the design size of the low-precision terrain area specifically includes, for example, 0.1 km×0.1 km, and the design terrain specifically includes a river with a varying river channel width, and the flow direction of the river is determined to be from north to south.
After the topographic data of the target topographic region is obtained, the topographic attribute information of each sub-topographic region contained in the target topographic region can be determined using the topographic data of the target topographic region. Here, first, a sub-terrain area in the target terrain area will be described. Since the design size of the target terrain area is generally larger, in order to reduce the workload when the target terrain area is designed, so as to improve the design efficiency of the target terrain area, the target terrain area is divided into a plurality of sub-terrain areas with smaller sizes, for example, the target terrain area is divided into sub-terrain areas with the sizes of 10 meters×10 meters. Here, the size of the cut is not limited, nor is the manner of the cut. After the sub-terrain areas with smaller sizes are obtained through segmentation, the sub-terrain areas can be distributed to different designers for synchronous design, and then the overall design efficiency of the target terrain areas can be improved.
For the obtained terrain data, since the terrain data can reflect the overall design of the target terrain area, for each sub-terrain area divided by 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 areas specifically includes information indicating a target object to be deployed in each sub-terrain area, and a deployment position of the target object in the sub-terrain area.
Exemplary, referring to fig. 3, a schematic diagram of determining topographic attribute information of a sub-topographic region is provided according to an embodiment of the present disclosure. In fig. 3 (a), a schematic diagram of a target terrain area is shown, the specific design size of which is 10 km×10 km, and the target terrain area is divided into 3×3 sub-terrain areas for simplicity of explanation. For the terrain data in fig. 2, a similar division may also be made to determine corresponding terrain attribute information for the sub-terrain areas divided in fig. 3, based on the terrain data at the corresponding locations. Taking the sub-terrain area at the middle position in the target terrain area shown in fig. 3 (a), that is, the sub-terrain area designed in fig. 3 (b), a segment including a river in the sub-terrain area can be determined from the terrain data of the corresponding position in fig. 2, and the inflow position and outflow position of the river of the segment on the sub-terrain area, and the direction of the river, that is, the deployment position of the river of the segment in the sub-terrain area can be determined.
In addition, for the sub-terrain area, other objects, such as sand and stone or grass, can be additionally added besides the partial objects determined by constraint of the terrain data, such as the river described above, so as to further refine and enrich the sub-terrain area. For other sub-terrain areas in the target terrain area, corresponding terrain attribute information may also be determined in a similar manner, and detailed description thereof will not be repeated here.
In the case where the topographic attribute information corresponding to the sub-topographic area is determined in S102, topographic patch data may be generated for any sub-topographic area based on the topographic attribute information corresponding to the sub-topographic area.
In particular implementations, the terrain patch data may be generated for a sub-terrain region based on object patch data corresponding to at least one target object to be deployed on the sub-terrain region, respectively, and deployment locations of the at least one target object corresponding to the at least one target object in the sub-terrain region, respectively.
Here, the target object to be deployed may include, for example, a river, a sand, a grass, or the like designed on the sub-terrain area as described above. For these target objects, for example, corresponding patch data may be predetermined. When the topographic patch data is generated for the sub-topographic area, the topographic patch data can be generated for the sub-topographic area more efficiently by calling the corresponding patch data and according to the corresponding deployment position of the target object in the sub-topographic area. In this way, the efficiency of rendering the display can also be correspondingly improved.
For S103, when determining the terrain patch data corresponding to each sub-terrain region in the target terrain region, the sub-terrain regions may be subjected to the stitching process according to the positions of the sub-terrain regions in the target terrain region, and the terrain patch data corresponding to each sub-terrain region may be updated based on the obtained stitching result.
In specific implementation, when the sub-terrain areas are spliced, the method comprises the steps of determining a plurality of positions to be spliced corresponding to the sub-terrain areas based on the positions of the sub-terrain areas in the target terrain areas, selecting a current position to be spliced from the plurality of positions to be spliced according to a preset splicing sequence, and carrying out splicing on a first sub-terrain area and a second sub-terrain area which are related to the current position to be spliced to obtain a splicing result.
Specifically, since each sub-terrain area exists alone but is part of the target terrain area, the sub-terrain areas can be spliced into the target terrain area in accordance with the position of each sub-terrain area in the target terrain area. In one possible case, the sub-terrain areas are rectangular, and when stitching, the sub-terrain areas are stitched with other sub-terrain areas that are located adjacent to the target terrain area by adjacent rectangular boundaries. Here, in the two sub-terrain areas to be spliced, adjacent boundaries include the positions to be spliced.
Exemplary, referring to fig. 4, a schematic diagram of a sub-terrain area in a stitching process according to an embodiment of the present disclosure is shown. In fig. 4, a plurality of sub-terrain areas demarcated from the target terrain area of fig. 3 (a) are specifically included. The positions to be spliced are arranged between two adjacent sub-terrain areas, and particularly, part of the positions to be spliced are marked in fig. 4. For each sub-terrain area, the corresponding position to be spliced when splicing other sub-terrain areas can be correspondingly determined.
In the case of determining a plurality of positions to be spliced, the sub-terrain areas may be spliced. In one possible case, since the data size of the topographic patch data of the sub-topographic area is large, if the stitching process is simultaneously performed on all sub-topographic areas of the target topographic area, the data size of the required process is also large, and the computational power of the computer device may not be able to be borne. Therefore, when splicing the sub-terrain areas, the number of the sub-terrain areas which can be spliced in one splicing processing period can be determined according to the calculation force of the computer equipment, and then a part of positions to be spliced are selected from a plurality of positions to be spliced to be used as the current positions to be spliced. Or the current position to be spliced can be sequentially selected according to a preset splicing sequence, for example, the preset splicing sequence is to splice the transverse position to be spliced firstly, then splice the longitudinal position to be spliced, splice the first sub-terrain area and the second sub-terrain area which are related to the transverse position to be spliced firstly in sequence, and splice the longitudinal position to be spliced after all the transverse positions to be spliced are spliced.
After the current position to be spliced is selected, the first sub-terrain area and the second sub-terrain area associated with the current position to be spliced can be spliced, so that a splicing result is obtained. Specifically, since the splicing process of the sub-terrain areas specifically relates to splicing boundaries of the sub-terrain areas, when the splicing is performed, 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 based on the current position to be spliced, and then the splicing process is performed on the first sub-terrain area and the second sub-terrain area based on the first splicing boundary and the second splicing boundary, so that a splicing process result is obtained.
Here, since the sub-terrain area corresponds to the terrain attribute information, the deployment position of the target object in the target terrain area, such as the inflow position, outflow position, direction of the river, and the like, of the sub-terrain area can be determined. For the target terrain area, continuity exists among sub-terrain areas containing the same object, such as river in the target terrain area has no fracture in a plurality of covered sub-terrain areas, and river beds are continuous and consistent in direction. Therefore, when two adjacent sub-terrain areas are spliced, two corresponding splicing boundaries need to be determined when the two sub-terrain areas are spliced. By utilizing the current position to be spliced, a first splicing boundary is determined for the associated first sub-terrain area, and a second splicing boundary is determined for the associated second sub-terrain area, so that the situation of violating the geographic rule can not occur after splicing.
Exemplary, referring to fig. 5, another schematic diagram of stitching sub-terrain areas provided for an embodiment of the present disclosure, specifically including the sub-terrain areas shown in fig. 4 as well. In fig. 5, two sub-topographical areas associated with one position to be spliced are specifically shown, including a first sub-topographical area, numbered 2, and a second sub-topographical area, numbered 5. For this position to be spliced, a first splice boundary a1 in the first sub-area and a second splice boundary a2 in the second sub-area may be determined, with which first splice boundary a1 and second splice boundary a2 the first sub-area and the second sub-area may be spliced correctly, as shown for example in fig. 5 (a). If the splicing boundary corresponding to the sub-area associated with the position to be spliced is not determined, a situation as shown in fig. 5 (b), that is, the splicing boundary a1 of the first sub-area is spliced with the splicing boundary b of the second sub-area, the situation may occur in the target terrain area, the direction of the river is changed against the geographic rule on the sub-terrain area with the reference number of 5, and a fracture occurs, that is, a splicing error of the sub-terrain area occurs.
With respect to S104, after updating the terrain patch data corresponding to each sub-terrain area based on the obtained stitching result, the target terrain patch data of the target terrain area may be determined by using the updated terrain patch data corresponding to each sub-terrain area, and the target terrain area may be rendered and displayed based on the target terrain patch data.
Here, since accuracy in splicing can be ensured when the sub-terrain areas are subjected to splicing processing, the target terrain patch data obtained by using the splicing processing result can also ensure that the target object has logic in display, so that the authenticity of the target terrain areas after rendering and displaying can be improved.
In another embodiment of the present disclosure, a specific manner of rendering and displaying the target terrain area again after the terrain data is modified is also provided. In a specific implementation, before determining the target topographic patch data of the target topographic area based on the updated topographic patch data corresponding to each sub-topographic area, a first target sub-topographic area associated with the modification operation may be determined from among the sub-topographic areas and the topographic attribute information corresponding to the first target sub-topographic area may be updated in response to the modification operation of the topographic data, and the first target sub-topographic area and the sub-topographic area adjacent to the first target sub-topographic area in each sub-topographic area may be spliced based on the position of the first target sub-topographic area in the target topographic area and the topographic patch data generated based on the updated topographic attribute information of the first target sub-topographic area and other sub-topographic area associated with the first target sub-topographic area.
For example, referring to fig. 6, a schematic diagram of another terrain data provided for an embodiment of the present disclosure is shown, where the shape of the bed of the river is modified at the dashed box numbered 2, and the original straight shape is modified to be curved, as compared to the terrain data shown in fig. 2. In this modification operation, the modification is specifically performed at the dashed box numbered 2, and thus the first target sub-terrain area associated with the modification operation is the sub-terrain area corresponding thereto. Since the shape of the river bed is modified, the terrain attribute information of the first target sub-terrain area can be updated.
After the updated topographic attribute information of the first target sub-topographic area is obtained, topographic patch data of the first target sub-topographic area may be generated as well, and specific modes may be referred to the corresponding description, and no repeated description is given here. After the topographic patch data of the first target sub-topographic region is determined, a sub-topographic region adjacent to the first target sub-topographic region may be determined from among the sub-topographic regions and the stitching process may be repeated to update the topographic patch data of the sub-topographic regions and redetermine the target topographic patch data of the target topographic region.
In this way, for the case that only a small modification is made in the terrain data, a small portion of the first target sub-terrain area requiring the updating of the terrain patch data can be determined according to the modification operation, and the splicing process is performed again, so that the splicing operation is not required to be performed again on all sub-terrain areas under the target terrain area again, the consumed calculation force is less, and the efficiency is higher.
In another embodiment of the present disclosure, a specific manner of rendering and displaying the target terrain area again after expanding the target terrain area is provided. In one possible case, if the target terrain area is rendered and displayed, and then the expansion requirement on the target terrain area is further provided, the target terrain area can be further expanded by taking the sub-terrain area as a unit on the basis of the current target terrain area.
In specific implementation, the method comprises the steps of responding to the expansion operation of the target topographic region, determining a sub-topographic region to be expanded corresponding to the expansion operation, determining a second target sub-topographic region adjacent to the sub-topographic region to be expanded from the sub-topographic regions, generating target topographic patch data of the sub-topographic region to be expanded based on target topographic attribute information determined for the sub-topographic region to be expanded, conducting expansion splicing processing on the sub-topographic region to be expanded and the second target sub-topographic region by utilizing the target topographic patch data and the topographic patch data corresponding to the second target sub-topographic region, updating the target topographic patch data based on the obtained expansion splicing processing result, and rendering and displaying the target topographic region after the expansion operation based on the updated target topographic patch data.
In one possible scenario, the sub-terrain area may be expanded at the outer edge of the target terrain area. After the sub-terrain area to be expanded is determined, the target terrain attribute information can be similarly determined for the sub-terrain area to be expanded, so that corresponding target terrain patch data can be determined. 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 in position can be determined first, and then the target terrain attribute information of the sub-terrain area to be expanded is determined based on the terrain attribute information of the second target sub-terrain area.
Exemplary, referring to fig. 7, a schematic diagram of a sub-terrain area to be extended according to an embodiment of the present disclosure is shown. The sub-terrain area to be expanded may determine a sub-terrain area adjacent to the location in the target terrain area, i.e., a second target sub-terrain area labeled 2. The target terrain attribute information of the sub-terrain area to be expanded may be constrained according to the terrain attribute information of the second target sub-terrain area, such as in fig. 7, the direction of the river of the second target sub-terrain area at the upstream position and the position of the river bed are determined in the sub-terrain area to be expanded. Therefore, even if the target terrain area displayed by current rendering is amplified, the displayed target object cannot lack the display logic, and the authenticity of the target terrain area after the expansion is ensured.
After the target terrain attribute information of the sub-terrain area to be expanded is determined, corresponding target terrain patch data can be determined, the sub-terrain area to be expanded and the second target sub-terrain area can be spliced by utilizing the terrain patch data of the second target sub-terrain area, the target terrain patch data of the target terrain area is updated, and the expanded target terrain area is rendered and displayed by utilizing the updated target terrain patch data.
Therefore, when the target terrain area is expanded, the terrain data of the target terrain area does not need to be determined again, the target terrain area is rendered and displayed by repeatedly utilizing the terrain data, the operation is simpler, and the efficiency is higher.
