[0018] Exemplary embodiments of the present disclosure will be described more fully hereinafter with reference to the accompanying drawings.

[0019] The accompanying drawings are schematic diagrams of the present disclosure and are not necessarily drawn to scale. Some of the block diagrams shown in the accompanying drawings may be functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or in hardware modules or integrated circuits, or in networks, processors or microcontrollers. The embodiments can be implemented in various forms and should not be construed as being limited to the examples set forth herein. The features, structures or characteristics described in the present disclosure may be combined in one or more embodiments in any suitable manner. In the description below, many specific details are provided to provide a full description of the embodiments of the present disclosure. However, those skilled in the art should appreciate that one or more specific details may be omitted when implementing the technical solution of the present disclosure, or one or more specific details may be replaced by other methods, components, devices, steps, etc.

[0020] In the related art, the required prefabricated road models are manually placed in the game scene through the art scene editor to generate virtual roads. This method requires a lot of manpower and time costs, has low generation efficiency, and is not suitable for game projects of larger sizes.

[0021] In the related art, a road model is generated by drawing a road curve of a specific shape and using a programmed road model generation algorithm according to the direction of the drawn road curve. In this way, the attributes that the road curve can carry are greatly restricted, and the artistic effects that can be achieved are relatively simple. Once the requirements change, a large amount of additional development costs will be generated, and the controllability, flexibility and diversity are poor.

[0022] In view of one or more of the above problems, exemplary embodiments of the present disclosure provide a virtual road generation method, a virtual road generation device, a computer program product, and an electronic device.

[0023] In an optional embodiment, reference Figure 1 As shown, a flowchart of a virtual road generation method is provided, which specifically includes the following steps S110 to S130:

[0024] Step S110, obtaining a road control curve, the road control curve is composed of a plurality of curve segments; each curve segment is respectively configured with a segment control parameter;

[0025] Step S120, determining a target road model unit corresponding to each curve segment from the candidate road model units according to the segment control parameters corresponding to each curve segment, and adjusting the target road model unit corresponding to each curve segment;

[0026] Step S130, according to the position of each curve segment in the road control curve, the target road model units corresponding to each curve segment are spliced ​​to obtain a virtual road matching the road control curve.

[0027] Figure 1 In the method shown, the road control curve is composed of multiple curve segments and each curve segment is respectively configured with a segment control parameter, so that the user only needs to adjust the segment control parameters to meet various road production requirements, which can enhance the controllability, flexibility and diversity of road model generation to a certain extent; through the segment control parameters corresponding to each curve segment in the road control curve, the corresponding road model component unit is selected from the candidate road model unit and spliced ​​after adjustment, without the need to start model production from scratch, which not only improves the generation efficiency of virtual roads but also ensures the generation quality of virtual roads, and can be better applied to game projects of larger sizes.

[0028] Below Figure 1 Provide detailed instructions for each step.

[0029] In step S110, a road control curve is obtained, where the road control curve is composed of a plurality of curve segments; each curve segment is respectively configured with a segment control parameter.

[0030] The road control curve refers to a curve used to control the type and shape of virtual road generation. The segment control parameter refers to a control parameter used to control the type and shape of the road model at the predefined curve segment level, which may include but is not limited to attribute types such as road type, road height, road width, and road length. The attribute parameter values ​​can be flexibly edited by the user according to needs, and this disclosure does not specifically limit this.

[0031] Optionally, the road control curve may be composed of multiple curve segments, and each curve segment may be composed of at least two control points. Taking the case where a curve segment is composed of two control points as an example, when there are 5 control points on a road control curve without bifurcations, 4 curve segments may be formed.

[0032] In some embodiments, a road control curve consisting of multiple curve segments can be edited by a curve editing tool for use. Exemplarily, the road control curve can be obtained by a curve editing tool in a game engine, and a specific preset format (e.g., json format) is used as a carrier for storage to produce a road control curve. When a road control curve produced by a game engine is obtained by a three-dimensional computer graphics software (e.g., Houdini), the stored file in a specific preset format can be converted into a usable curve format in the three-dimensional computer graphics software to facilitate identification of various curve data associated with the road control curve, such as road control parameters at the overall level, road control parameters at the segment level (i.e., segment control parameters), and road control parameters at the control point level (i.e., node control parameters). It should be noted that the types of road control parameters at different hierarchical structures can be pre-set or added by the user, and this disclosure does not limit this.

[0033] In an optional implementation, after the road control curve is acquired, the following steps may be performed: smoothing each curve segment in the road control curve to obtain each adjusted curve segment.

[0034] For example, it is possible to calculate whether the height transition of each curve segment and adjacent curve segments in the road control curve exceeds a preset height transition threshold, that is, whether the height rise or fall value within a unit length exceeds a preset height difference. If so, the curve portion exceeding the preset height transition threshold can be height-smoothed. Through height smoothing, the height transition can be dispersed to a larger range for transition, making the generated virtual road smoother.

[0035] For example, it is possible to calculate whether the curvature of the corners of each curve segment and the adjacent curve segments in the road control curve exceeds a preset curvature threshold. If so, the portion of the curve that exceeds the preset curvature threshold can be subjected to curvature smoothing. Through curvature smoothing, the turning angle can be dispersed over a larger range for transition, making the generated virtual road smoother. Furthermore, by performing curvature smoothing on the road control curve, it is also possible to avoid wrinkles of varying degrees in areas with excessively large turning angles after the road model unit is applied, thereby improving the performance of the virtual road.

[0036] In step S120, according to the segment control parameters corresponding to each curve segment, the target road model unit corresponding to each curve segment is determined from the candidate road model units, and the target road model unit corresponding to each curve segment is adjusted.

[0037] The candidate road model unit refers to a pre-created road splicing component. Various road splicing components that may be used to generate virtual roads in game scenes, namely candidate road model units, can be pre-made, and these road splicing components are stored separately in a preset format (for example, fbx format) for use.

[0038] Exemplarily, the candidate road model units may include, but are not limited to, model units for generating straight roads and their variants, model units for generating intersections with merging angles of specific angles, etc., which are not specifically limited in the present disclosure.

[0039] Exemplarily, the candidate road model units may also include model units with different numbers of lanes, such as 8 lanes, 6 lanes, 4 lanes, etc., which is not specifically limited in the present disclosure.

[0040] Exemplarily, the candidate road model units may also include, but are not limited to, ordinary roads, tunnels, elevated roads, ramps, etc., which are not specifically limited in the present disclosure.

[0041] It should be noted that, in practical applications, the road model units can be divided into different road types according to actual needs for users to select and configure.

[0042] Optionally, the created candidate road model units can be put into storage for subsequent use. Exemplarily, the asset storage panel developed in the Unreal Engine can be used to implement storage management. Specifically, for ease of management, the road model unit can be exported to the corresponding path in a specific preset format (such as fbx format) while exporting the configuration file (such as a json file) of the road model unit to the corresponding path. Optionally, the stored road model units can be pre-processed for normalization and scaling to facilitate subsequent use. The present disclosure generates the road model units required for a complete virtual road through storage management, i.e., the candidate road model units, thereby improving the convenience of managing the number and types of model assets. When more road model unit variants need to be added, it is only necessary to add a new form bar in the component model storage interface to complete the data storage of the model unit and the export of the model unit.

[0043] Optionally, a road type parameter may be defined in the segment control parameter, so as to determine a target road model unit corresponding to each curve segment from the candidate road model units based on the road type parameter corresponding to each curve segment.

[0044] The target road model unit refers to a model unit extracted from the candidate road model units and matching the segmentation control parameters of the curve segment.

[0045] For example, when adjusting the target road model unit corresponding to each curve segment, deformation, rotation, scaling and other types of adjustments may be performed based on each curve segment, so as to flexibly control the presentation effect of the target road model through the curve segment.

[0046] Optionally, road shape parameters may also be defined in the segment control parameters so as to adjust the target road model unit corresponding to each curve segment at the curve segment level.

[0047] In an optional implementation, the segment control parameters include road type parameters and road shape parameters. According to the segment control parameters corresponding to each curve segment, the target road model unit corresponding to each curve segment is determined from the candidate road model units, and the target road model unit corresponding to each curve segment is adjusted. Figure 2 The steps shown are to achieve this:

[0048] Step S210, determining a target road model unit corresponding to each curve segment from candidate road model units according to the road type parameters corresponding to each curve segment;

[0049] Step S220: adjusting the target road model unit corresponding to each curve segment according to the road shape parameter corresponding to each curve segment.

[0050] The road type parameter refers to the configuration parameter for the road model unit type, such as a straight road, a cross-merging road, an 8-lane, a 6-lane, or a 4-lane road, a normal road, a tunnel, an elevated road, or a ramp.

[0051] Exemplarily, the target road model unit that matches the road type parameters of each curve segment can be determined by reading the road type parameters corresponding to the corresponding curve segment recorded on each curve segment and comparing them with the configuration files of the stored candidate road model units.

[0052] After determining the target road model units that match the road type parameters of each curve segment, the target road model units may be further adjusted to improve the splicing effect between the target road model units.

[0053] Among them, the road shape parameters refer to control parameters that can affect the road shape (such as road width, road length, road height, road curvature, etc.). By adjusting the target road model unit corresponding to each curve segment according to the road shape parameters corresponding to each curve segment, the target road model unit can better adapt to the road control curve.

[0054] Exemplarily, the target road model unit corresponding to each curve segment may be scaled according to the road width parameter and / or road length attribute of each curve segment.

[0055] Exemplarily, the target road model unit corresponding to each curve segment may be deformed according to the road height parameter and / or the road curvature parameter of each curve segment.

[0056] Figure 2 The steps in realize the adjustment of the target road model unit at the curve segment level, which can improve the flexibility and freedom of user editing.

[0057] In an optional embodiment, each curve segment is composed of at least two control points, each control point is respectively configured with a node control parameter, and the target road model unit corresponding to each curve segment is adjusted. It can also be achieved by the following steps: according to the node control parameters corresponding to each control point, the target road model unit corresponding to each curve segment is adjusted.

[0058] The node control parameters refer to control parameters at a predefined node level for controlling the shape of the road model.

[0059] Optionally, road width parameters, road height parameters, road curvature parameters and other types can be defined in the node control parameters to adjust the target road model units corresponding to each curve segment from the node level to improve the editing accuracy of the virtual road. It should be noted here that in actual application, some road control parameters can be set at the node level, at the curve segment level, or at the overall level. Different settings at different levels will result in different performance accuracy of the virtual road. For example, road width parameters, road height parameters, road curvature parameters, etc. can be customized according to actual needs, and this disclosure does not specifically limit this. By customizing road control parameters at different levels, users can achieve a high degree of controllability in the generation of virtual roads.

[0060] Exemplarily, the target road model unit corresponding to each curve segment may be scaled according to the road width parameter corresponding to each control point.

[0061] Exemplarily, the target road model unit corresponding to each curve segment may be deformed according to the road height parameter and / or road curvature parameter corresponding to each control point.

[0062] In an optional embodiment, the above-mentioned adjustment of the target road model unit corresponding to each curve segment can also be achieved through the following steps: obtaining the overall control parameters defined for the road control curve, and adjusting the target road model unit corresponding to each curve segment according to the overall control parameters.

[0063] The overall control parameter refers to a control parameter used to control the shape of the road model at a predefined overall level. For example, the overall control parameter may define a road material, such as an asphalt road, a concrete road, etc., which is not specifically limited in the present disclosure.

[0064] In some embodiments, the material of the target road model unit may be adjusted according to the road material parameters.

[0065] By adjusting the target road model unit through control parameters at different levels, the quality of virtual road generation can be ensured to a certain extent while ensuring the convenience of user editing.

[0066] In an optional embodiment, after obtaining the road control curve as mentioned above, the following steps can also be performed: determine the curve intersection point between each curve segment, and judge whether the angle between the curve segments connected to the curve intersection point meets the preset conditions; if not, adjust the angle between the curve segments connected to the curve intersection point so that the angle meets the preset conditions.

[0067] Exemplarily, a curve intersection point refers to a control point connected to at least three curve segments, that is, a point where a bifurcation occurs in a road control curve, which is a subset of the control points.

[0068] The preset condition refers to a condition set in advance for adjusting the curve intersection portion. By setting the preset condition, the curve intersection angle can be normalized so that a more suitable target road model unit can be determined from the candidate road models.

[0069] In an optional embodiment, the above-mentioned judgment of whether the angle between the curve segments connected to the curve intersection point meets the preset conditions can be achieved through the following steps: judging whether the angle between the curve segments connected to the curve intersection point belongs to a subset of the preset angle set.

[0070] Among them, the preset angle set refers to a set of one or more pre-set normalized angles, such as a 30-degree angle, a 45-degree angle, a 90-degree angle, etc., which can correspond to the road model units related to the intersection and convergence angle in the candidate road model units to normalize the fork angles and increase the fit between the road model units and the curves.

[0071] Exemplarily, it can be determined whether the angle between the curve segments connected to the curve intersection point belongs to a subset of a preset angle set. If so, it can be considered that the preset condition is met; if not, it can be considered that the preset condition is not met.

[0072] If the angle between the curve segments connected to the curve intersection point meets the preset conditions, the angle between the curve segments connected to the curve intersection point may not be adjusted.

[0073] If the angle between the curve segments connected to the curve intersection point does not meet the preset conditions, the angle between the curve segments connected to the curve intersection point can be adjusted.

[0074] For example, Figure 3 As shown, a schematic diagram of a process for adjusting the angle is provided, which may specifically include the following steps:

[0075] Step S301, determining the curve intersection point between each curve segment;

[0076] Step S302, determining whether the angle between the curve segments connected to the curve intersection point belongs to a subset of the preset angle set; if yes, proceed to step S303, if no, proceed to step S304;

[0077] Step S303, not adjusting the angle between the curve segments connected to the curve intersection point;

[0078] Step S304: adjusting the angle between the curve segments connected to the curve intersection point so that the angle belongs to a subset of the preset angle set.

[0079] In an optional embodiment, the above-mentioned adjustment of the angle between the curve segments connected to the curve intersection point so that the angle satisfies the preset condition can be achieved through the following steps: determining the angle difference between the angle between the curve segments connected to the curve intersection point and each angle in the preset angle set; determining the target angle from the preset angle set based on the angle difference; and adjusting the angle between the curve segments connected to the curve intersection point based on the target angle.

[0080] Exemplarily, the angle difference between the angle between the curve segments connected to the curve intersection and the angles in the preset angle set can be determined, and the angle with the smallest angle difference is selected from the preset angle set as the target angle, and the angle between the curve segments connected to the curve intersection is adjusted to the target angle to normalize the fork angle.

[0081] In an optional embodiment, the above-mentioned curve intersection is configured with an intersection control parameter, and the target road model unit corresponding to each curve segment is adjusted. It can also be achieved by the following steps: according to the intersection control parameter, the target road model unit corresponding to the curve segment connected to the curve intersection is adjusted.

[0082] The intersection control parameters refer to the parameters set at the intersection level to control the connection of forked roads, which can realize flexible editing of forked roads and further enhance the controllability of road generation. For example, the intersection control parameters can define parameters such as width control parameters and rotation control parameters.

[0083] In an optional embodiment, the above-mentioned adjustment of the target road model unit corresponding to the curve segment connected to the curve intersection point according to the intersection control parameters can be achieved through the following steps: scaling the target road model unit corresponding to the curve segment connected to the curve intersection point according to the width control parameters in the intersection control parameters; and / or rotating the target road model unit corresponding to the curve segment connected to the curve intersection point according to the rotation control parameters in the intersection control parameters.

[0084] For example, when scaling the target road model unit corresponding to the curve segment connected to the curve intersection point according to the width control parameter in the intersection control parameter, the target road model unit may be scaled as a whole, or only the connecting end of the target road model unit may be scaled. The present disclosure does not specifically limit this.

[0085] For example, when rotating the target road model unit corresponding to the curve segment connected to the curve intersection point according to the rotation control parameters in the intersection control parameters, the orientation of the target road model unit is adjusted, which can flexibly meet different placement scenarios of the road model unit.

[0086] In step S130, according to the position of each curve segment in the road control curve, the target road model units corresponding to each curve segment are spliced ​​to obtain a virtual road matching the road control curve.

[0087] Specifically, the corresponding target road model units may be spliced ​​together in sequence according to the positions of the curve segments in the road control curve, so as to obtain a virtual road matching the road control curve.

[0088] In an optional embodiment, the connecting ends of the interconnected target road model units may be deformed or scaled according to the road shape parameters corresponding to the interconnected curve segments and / or the node control parameters of the connecting control points corresponding to the interconnected curve segments, so as to achieve seamless and smooth connection between the model units and enhance the presentation effect of the virtual road.

[0089] For example, Figure 4 As shown, a flowchart of generating a virtual road based on road control curve control is provided, which may specifically include the following steps:

[0090] Step S401, obtaining a road control curve, the road control curve is configured with overall control parameters; the road control curve is composed of multiple curve segments, each curve segment is respectively configured with segment control parameters; each curve segment is composed of at least two control points, each control point is respectively configured with node control parameters;

[0091] Step S402, determining a target road model unit corresponding to each curve segment from candidate road model units according to a road type parameter in a segment control parameter corresponding to each curve segment;

[0092] Step S403, adjusting the target road model unit corresponding to each curve segment according to the overall control parameter, the node control parameter corresponding to each control point, and the road shape parameter in the segment control parameter corresponding to each curve segment;

[0093] Step S404: splicing the target road model units corresponding to each curve segment according to the position of each curve segment in the road control curve to generate a virtual road.

[0094] Figure 4In the steps shown, by dividing the road control curve into different levels and subdividing the attribute configuration, the control accuracy of the virtual road can be achieved for each curve segment or even each control point, rather than the entire curve. This does not need to rely on the fixed value of the tool's internal algorithm, and can improve the diversity and controllability of the virtual road performance.

[0095] The exemplary embodiment of the present disclosure also provides a virtual road generation device, referring to Figure 5 As shown, the virtual road generating device 500 may include the following program modules:

[0096] The control curve acquisition module 510 is used to acquire a road control curve, which is composed of a plurality of curve segments; each curve segment is respectively configured with a segment control parameter;

[0098] The road model generation module 530 is used to splice the target road model units corresponding to each curve segment according to the position of each curve segment in the road control curve, so as to obtain a virtual road matching the road control curve.

[0099] In an optional implementation, based on the above-mentioned solution, after obtaining the road control curve, the virtual road generation device 500 may further include: a curve smoothing processing module, which is used to smooth each curve segment in the road control curve to obtain each adjusted curve segment.

[0102] In an optional implementation, based on the above solution, the model unit adjustment module is further used to obtain the overall control parameters defined for the road control curve, and adjust the target road model unit corresponding to each curve segment according to the overall control parameters.

[0103] In an optional embodiment, based on the above scheme, after obtaining the road control curve, the virtual road generation device 500 may also include: an angle judgment module, used to determine the curve intersection point between each curve segment, and judge whether the angle between the curve segments connected to the curve intersection point meets the preset conditions; an angle adjustment module, used to adjust the angle between the curve segments connected to the curve intersection point if not, so that the angle meets the preset conditions.

[0107] In an optional embodiment, based on the aforementioned scheme, the model unit adjustment module can be configured to: scale the target road model unit corresponding to the curve segment connected to the curve intersection according to the width control parameter in the intersection control parameter; and / or rotate the target road model unit corresponding to the curve segment connected to the curve intersection according to the rotation control parameter in the intersection control parameter.

[0108] The specific details of each part of the above-mentioned device have been described in detail in the implementation method of the method part. The undisclosed details can be found in the implementation method of the method part, so they will not be repeated here.

[0109] The exemplary embodiment of the present disclosure further provides a computer program product, which includes a computer program, and when the computer program is executed by a processor, the above-mentioned virtual road generation method is implemented.
