Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In accordance with an embodiment of the present invention, there is provided an embodiment of a terrain stitching method, it is noted that the steps illustrated in the flowchart of the figure may be performed in a computer system such as a set of computer-executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.
Considering that three-dimensional design software has many mature and convenient processing schemes, Houdini (a kind of three-dimensional design software) in the current mainstream three-dimensional software is the only three-dimensional software with abundant scene editing tool chains, such as topographic and geomorphic calculus, spreading and clustering placement of vegetation models, automatic tool processes, and the like. Due to the unique resource format of the mosaic engine architecture (Messiah Server, which may be referred to as Messiah for short), a customized input/output interface needs to be written when interacting with other software, so that the mosaic engine architecture cannot directly interact with Houdini. Therefore, when processing the terrain of the existing scene in Messiah, an art worker is usually required to edit the terrain manually. However, the existing scene terrain processing mode often brings a large amount of repeated work to the art personnel, which causes that the efficiency of terrain processing is not high and the user experience degree is not high. Based on the above, the embodiment of the invention provides a terrain splicing method, a terrain splicing device, an electronic terminal and a storage medium, which improve the processing efficiency and the use convenience of art workers during scene processing, and further effectively improve the user experience.
Fig. 1 is a schematic flow chart of a terrain stitching method according to an embodiment of the present invention. And providing a graphical user interface through the terminal, wherein the graphical user interface comprises a terrain editing interface which comprises a terrain to be edited. For example, the method can be applied to a terminal device capable of running three-dimensional design software, and the graphical user interface can be an interactive interface provided by the three-dimensional design software. The three-dimensional design software can be Houdini, as shown in fig. 1, and the method mainly comprises the following steps:
s110, determining an overlapping area between the target sub-terrain and the sub-terrain to be spliced.
The target sub-terrain and the sub-terrain to be spliced can refer to terrain which completes mapping layering and terrain height editing.
In general, since a plurality of art editing users edit a terrain, it is necessary to splice the terrains when editing is completed.
The method and the device for splicing the terrain can be used for splicing operation triggered after a user submits a splicing request, the splicing request can comprise the edited terrain, and the splicing request can be used for indicating that the finished terrain is spliced into the whole terrain.
In the embodiment of the application, the target sub-terrain and the sub-terrain to be spliced can be terrains edited by different users, and can also be terrains edited by the same user. For example, because the scale of the terrain is usually large, the terrain to be edited can be divided into a plurality of sub-terrains to be edited, the plurality of sub-terrains to be edited can be distributed to one or a plurality of users for editing, after the editing is completed conveniently, the plurality of terrains completed by editing can be spliced, one of any two adjacent terrains in the plurality of terrains completed by editing is a target sub-terrain, and the other is a sub-terrain to be spliced; or, for any two adjacent terrains in the edited plurality of terrains, the first submitted one is the target sub-terrains, and the later submitted one is the sub-terrains to be spliced.
For example, the landforms to be spliced include a first landform handled by a first art editing user, a second landform handled by a second art editing user, and a third landform handled by a third art editing user, where the second landform and the third landform are both required to be spliced with the first landform, and at this time, the first landform is a target sub-landform, and the second landform and the third landform are to-be-spliced sub-landforms.
Therefore, in the resource updating process, the second art editing user and the third art editing user only need to update the voxel data resources in the second terrain and the third terrain respectively according to the first terrain for the second terrain and the third terrain, and do not need to update the voxel data resources in the first terrain, so that the resource updating is ensured not to conflict.
Various implementations may be included for the determination of the overlap region. In general, only edge local areas of the target sub-terrain and the terrain to be spliced are crossed and overlapped, although the two terrains in the transition area are both subjected to the same layered mixed mapping before processing, whether the edge transition is natural when the two terrains are put together cannot be guaranteed during different art editing, meanwhile, the height difference of the two terrains is large in the example, but the mixed transition between the two terrains cannot be so strong due to prior planning in the example project.
The edge area of one of the terrains can be modified to match the edge height and the hierarchical data of the other terrains, and as an example, the edge line of the target sub-terrains can be projected onto the sub-terrains to be spliced to obtain a projected edge line; and determining the area of one side, which is enclosed by the projection edge line and the sub-terrain to be spliced and is close to the target sub-terrain, as an overlapping area. In other words, the overlap region may be a region on the sub-feature to be spliced, and the overlap region is a projection of the target sub-feature on the sub-feature to be spliced.
And S120, cutting the sub-terrain to be spliced based on the overlapping area to obtain the target spliced sub-terrain.
In determining the overlap region, the overlap region may be clipped out of the sub-feature to be spliced in order to align the edges between the target sub-feature and the sub-feature to be spliced.
The performance required for data processing can be saved by performing the clipping process on the overlapped area.
After the overlapped area is determined, an edge boundary line between the target sub-terrain and the terrain to be spliced needs to be determined at first, the edge boundary line is located on the terrain to be spliced and can be cut according to the edge boundary line, so that the overlapped area is cut from the terrain to be spliced, the target spliced sub-terrain is obtained, and resources and performances required when the subsequent target sub-terrain and the target spliced sub-terrain are spliced can be saved.
And S130, splicing and transforming the target splicing sub-landforms based on the height difference of the boundary edges of the target splicing sub-landforms and the target splicing sub-landforms.
The stitching transformation is primarily intended to make a smooth transition between the target sub-terrain and the target stitching sub-terrain. The specific splicing transformation mode can comprise a plurality of modes.
For example, the height difference of the boundary edges of the target sub-terrain and the target stitching sub-terrain may be determined; determining a height transformation value of a sampling point on the target splicing sub-terrain based on the distance between the sampling point on the target splicing sub-terrain and the edge boundary line, wherein the closer the distance between the sampling point on the target splicing sub-terrain and the edge boundary line is, the closer the height transformation value is to the height difference; and carrying out splicing transformation on the sampling points on the target splicing sub-terrain based on the height transformation values.
The target sub-terrain and the target splicing sub-terrain are subjected to interpolation mixing based on the height transformation value by utilizing the mixing mask, so that the sampling points on the target splicing sub-terrain after splicing transformation are obtained.
The sampling points may include location information and mapping information; the position information after the change of the splicing sampling points on the target splicing sub-terrain and the mapping information after the change can be determined through difference value mixing. That is, the height values in the sampling points on the target stitching sub-terrain and the color values of the map can be updated based on the height transform values.
In some embodiments, a preset transform amplitude value may also be determined; and determining the height transformation value of the sampling point on the target splicing sub-terrain based on the preset transformation amplitude value and the distance between the sampling point on the target splicing sub-terrain and the edge boundary line.
The transform amplitude value may be determined according to actual needs, or may be configured in advance. For example, in response to a setting operation for a transform amplitude value, a new transform amplitude value is determined; and adjusting the height transformation value of the sampling point on the target splicing sub-terrain based on the new transformation amplitude value. For example, the transform amplitude value may be set by a drag operation. Based on the method, the dragging operation aiming at the sampling point on the target splicing sub-terrain can be responded, and the displacement of the dragging operation is determined; a new transform amplitude value is determined based on the magnitude of the displacement.
The transform amplitude value is used to indicate position information between adjacent sampling points and a variation amplitude of the map information. The larger the transformation amplitude value is, the larger the variation amplitude is, the more the transition is violent in appearance, correspondingly, the smaller the transformation amplitude value is, the smaller the variation amplitude is, and the transition is gentle in appearance. Suitable values may be selected based on experience. The transform amplitude value can also affect the area where the splicing transform needs to be performed. Wherein, the area needing to be spliced and changed can be only on the target splicing sub-terrain. The larger the transformation amplitude value is, the smaller the area needing splicing transformation is, the smaller the transformation amplitude value is, and the larger the area needing splicing transformation is, so that the splicing requirement can be met.
In some embodiments, in setting the transform amplitude value, only the transform amplitude of the position information on which the transform amplitude of the map information is determined may be set. The transform amplitude value may be a transform scale for the height difference, and the transform scale may be applied to the transform of the map information.
And S140, performing expansion processing on the spliced and transformed target spliced sub-terrain to obtain a spliced terrain.
In the embodiment of the invention, the heights of the target sub-terrain and the area corresponding to the sub-terrain to be spliced in the spliced and transformed target spliced sub-terrain gradually transition for a certain distance, but an obvious seam still can exist between the two areas. For example, if the terrain is likely to reappear as the line of sight (LOD) is zoomed out, the seam may appear due to level of Detail (LOD) processing. Based on the method, at least one expansion processing can be carried out on the first target area in the spliced and transformed target spliced sub-terrain to obtain the expanded first target area; the spliced terrain comprises a target sub-terrain and a stretched target splicing sub-terrain, and the stretched target splicing sub-terrain comprises a first target area.
The method comprises the following steps of determining expansion parameters, wherein the expansion parameters comprise expansion times and expansion distances; and carrying out at least one expansion treatment on the first target area in the spliced and transformed target spliced sub-terrain based on the expansion parameters.
The number of times of expansion can be determined based on the distance between the sampling point of the target sub-terrain and the sampling point of the spliced and transformed target spliced sub-terrain. The number of topographies is determined based on the intensity of the LOD. Wherein, the stronger the LOD intensity is, the more the expansion times are, so as to be able to produce better display effect.
By the embodiment of the invention, the overlapping area between the target sub-terrain and the sub-terrain to be spliced can be determined; cutting the sub-terrain to be spliced based on the overlapped area to obtain a target spliced sub-terrain; splicing and transforming the target splicing sub-landforms based on the height difference of the boundary edges of the target splicing sub-landforms and the target splicing sub-landforms; and carrying out expansion processing on the spliced and transformed target spliced sub-terrain to obtain a spliced terrain. Can be to the overlap region between the concatenation topography with this, tailor earlier, based on the difference in height between the terrain region after tailorring and carry out the concatenation transform to the terrain region after the transform carries out expansion processing, makes the transition region more natural through above-mentioned method, and there is not obvious seam, and visual experience is better, and the simple operation.
Considering as an art person, it may be necessary to manually adjust the effect in the view, in order to improve convenience and efficient interactive experience, and to simplify the operation and reduce unnecessary calculation amount as much as possible. Fig. 2 shows a schematic diagram of an editing interface for a terrain editing process applied to a terminal device running Houdini, with a terrain editing area on the left for presenting a current scene terrain, such as a large scene terrain which may be a game scene. The right side in fig. 2 is a node selection area for matching the node where the current terrain to be processed is located. As can be seen from the figure, the nodes include child nodes, that is, the nodes of the embodiment of the present invention can quickly browse information such as existing scenes, hierarchies, and Entity (Entity) of the scenes in a hierarchical tree manner, and import, edit, update, and export selected contents. The fine arts personnel can select the corresponding node according to the requirement of actual processing.
For ease of understanding, a schematic diagram of an interface for generating interactive nodes by pulling different hierarchical contents is illustrated, and referring to fig. 3, the interface can also encapsulate nodes by pulling different hierarchical contents for quickly generating nodes at a specified network location. Because the relevant parameters of each resource are more, the operation can be simplified as much as possible to enable the art to directly and quickly use each interactive node without knowing the parameters by dragging and selecting the generated nodes and presetting the deployment parameters, and the path does not need to be manually configured on the node.
The method can greatly improve the IO speed through the C + + HDK through multithreading management, greatly simplify the GUI interface, quickly browse the information of the existing scene, grading, scene Entity and the like through the hierarchical tree, and import, edit, update and export the selected content.
However, in the world editing process of messaiah (milea, a terrain editing engine), multiple persons edit on a single terrain at the same time, which easily causes resource update conflict and management confusion, each different zone (land parcel) has a different outline shape according to the art requirement during editing, but the terrain of messaiah can only keep a square structure, so that multiple terrains can be interlaced, but in the prior art, the terrain edge transition is mixed and matched according to adjacent terrains, only the alignment in height is realized, the transition of mapping distribution is not natural, and the following solutions are provided for the above problems.
As shown in fig. 4, fig. 4 shows two pieces of terrain (a first terrain 401 and a second terrain 402, wherein the first terrain 401 is a target sub-terrain, and the second terrain 402 is a sub-terrain to be spliced), which have been edited in messah, and art editors of the two terrains have edited the mapping layer and the terrain height according to the plan of the zone, and have hollowed out the terrain outside the zone according to the shape of the zone.
In this example, only the edge of two terrains is partially overlapped with the other terrains in a crossing way, and although the two terrains are both mapped by the same layered mixture in the transition area before processing, the two terrains cannot be guaranteed whether the edge transition is natural when the two terrains are put together in different art editions, and the height difference of the two terrains is larger in this example, but the mixed transition between the two terrains is not so strong by prior planning in an example project.
Based on the solution provided by the embodiment of the present invention, the edge area of one of the zones may be modified to match the edge height and hierarchical data of another zone.
First, as shown in fig. 5, it is necessary to determine an overlapping area 501 and perform a cropping process on the overlapping area to save performance, resulting in a terrain as shown in fig. 6.
A distance boundary line 502 is calculated for clipping based on the overlap region 501, and the distance from the sample point to the boundary line is used as an interpolation value for the post-transition blending.
The terrain shown in fig. 8 can be obtained by interpolating and mixing the heights of the two terrains and the layering values based on the mixed mask shown in fig. 7 and then deriving the terrains into messiah.
In fig. 8, it can be seen that the height between two zones has a gradual transition of a certain distance, but still has an obvious seam, and we need to make the zone at the junction of the zones perform expansion for edge protection, and the distance of the expansion can be calculated according to the distance between two adjacent sampling points of the terrain.
The functions can be integrated into a single houdini functional node, and after mixed planning is completed, the arts only need to update respective scenes, and the houdini can automatically update edge mixing, so that rapid area planning and iteration are achieved.
