[0020] In the related art, a virtual road is generated by manually placing a required prefabricated road model in a game scene through an art scene edit. This method requires a large amount of manpower and time cost, and has a low generation efficiency, which is not suitable for a larger size volume game project.

[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 drawn road curve. In this way, the attributes that can be carried by the road curve are limited, the artistic effects that can be achieved are simple, and a large amount of development cost is additionally generated once the requirements change, and controllability, flexibility and diversity are poor.

[0022] In view of one or more of the above problems, the 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, referring to Figure 1 As shown in the flowchart of the virtual road generation method, the method specifically includes the following steps S110 to S130:

[0024] In step S110, a road control curve is obtained, the road control curve being composed of a plurality of curve segments; each curve segment is respectively configured with a segment control parameter;

[0025] In step S120, according to the segment control parameter corresponding to each curve segment, a target road model unit corresponding to each curve segment is determined from a candidate road model unit, and the target road model unit corresponding to each curve segment is adjusted;

[0026] In step S130, according to the position of each curve segment in the road control curve, the target road model unit corresponding to each curve segment is 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 a plurality of 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 parameter to meet various road production requirements, and the controllability, flexibility and diversity of road model generation can be enhanced to a certain extent; by using the segment control parameter 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 adjusted for splicing, without starting from zero for model production, which not only improves the generation efficiency of the virtual road but also ensures the generation quality of the virtual road, and can be well applied to a game project with a large size.

[0028] Each step in Figure 1 will be described in detail below.

[0029] In step S110, a road control curve is obtained, the road control curve being 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 form of virtual road generation. The segment control parameter refers to a control parameter used to control the type and form of the road model at a predefined curve segment level, which can include but is not limited to road type, road height, road width, road length, and the like. The attribute parameter value can be flexibly edited by the user according to the requirements, and the present disclosure does not make specific limitations.

[0031] Optionally, the road control curve can be composed of multiple curve segments, and each curve segment can be composed of at least two control points. Taking a curve segment composed of two control points as an example, when five control points are provided on a road control curve without branching, four curve segments can be formed.

[0032] In some embodiments, the road control curve composed of multiple curve segments can be edited by a curve editing tool for use. For example, the road control curve can be obtained by a curve editing tool in a game engine, and a specific preset format (for example, a json format) is used as a carrier for storage to make the road control curve. When the road control curve made by the game engine is obtained by a three-dimensional computer graphics software (for example, Houdini), the stored file in the specific preset format can be converted into a usable curve format in the three-dimensional computer graphics software, so as to identify 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), road control parameters at the control point level (i.e., node control parameters), and the like. It should be noted that the types of road control parameters at different levels can be preset or added by the user, and the present disclosure does not make limitations in this regard.

[0033] In an optional embodiment, after obtaining the road control curve, the following step can be further performed: smoothing each curve segment in the road control curve to obtain adjusted curve segments.

[0034] For example, whether the height transition of each curve segment and the adjacent curve segment in the road control curve exceeds a preset height transition threshold, i.e., the height rise or fall value within a unit length exceeds a preset height difference value, can be calculated. If it exceeds, the curve part exceeding the preset height transition threshold can be subjected to height smoothing processing. Through height smoothing processing, the height transition can be dispersed to a larger range for transition, so that the generated virtual road is smoother.

[0035] Exemplarily, whether the turning angle of each curve segment and the adjacent curve segment in the road control curve exceeds a preset threshold of the turning angle can be calculated, and if the preset threshold of the turning angle is exceeded, the curve segment exceeding the preset threshold of the turning angle can be subjected to the turning angle smoothing processing. Through the turning angle smoothing processing, the turning angle can be dispersed to a larger range for transition, so that the generated virtual road is smoother. Furthermore, through the turning angle smoothing processing on the road control curve, the different degrees of wrinkle interlacing after the application of the road model unit in the area with the excessively large turning angle can be avoided, and the performance effect of the virtual road can be improved.

[0036] In step S120, the target road model unit corresponding to each curve segment is determined from the candidate road model units according to the segment control parameter corresponding to each curve segment, 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 can be used to generate a virtual road in a game scene, i.e., the candidate road model unit, 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 unit can include but is not limited to a model unit for generating a straight road and its variants, a model unit for generating a crossing angle of a specific angle, etc., which are not specifically limited in the present disclosure.

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

[0040] Exemplarily, the candidate road model unit can also include but is not limited to ordinary roads, tunnels, viaducts, ramps, etc., which are not specifically limited in the present disclosure.

[0041] It should be noted that in actual applications, the road model unit can be divided into different road types according to actual needs for user selection and configuration.

[0042] Optionally, the created candidate road model units can be managed in a warehouse for subsequent use. For example, the warehouse management can be implemented by using an asset warehouse panel developed in the Unreal Engine. Specifically, to facilitate management, the road model units can be exported in a specific preset format (e.g., fbx format) to the corresponding path while exporting the configuration file (e.g., json file) of the road model units to the corresponding path. Optionally, the warehouse-managed road model units can be normalized and scaled for subsequent use. The disclosure generates the road model units, i.e., candidate road model units, required for the complete virtual road through warehouse management, which improves the convenience of managing the number and types of model assets. When more road model unit variants are needed, the data warehouse of the model units and the export of the model units can be completed by adding a new form bar to the component model warehouse interface.

[0043] Optionally, a road type parameter can be defined in the segment control parameter, so as to determine the 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] wherein the target road model unit refers to the model unit extracted from the candidate road model units and matched with the segment control parameter of the curve segment.

[0045] For example, when adjusting the target road model unit corresponding to each curve segment, the target road model unit corresponding to each curve segment can be adjusted in terms of deformation, rotation, scaling, etc. based on each curve segment, so as to flexibly control the presentation effect of the target road model through the curve segment.

[0046] Optionally, a road form parameter can also be defined in the segment control parameter, so as to adjust the target road model unit corresponding to each curve segment from the curve segment level.

[0047] In an optional embodiment, the segment control parameter includes a road type parameter and a road form parameter, and the above-mentioned determination of the target road model unit corresponding to each curve segment from the candidate road model units based on the segment control parameter corresponding to each curve segment and the adjustment of the target road model unit corresponding to each curve segment can be implemented by the steps shown in Figure 2 .

[0048] Step S210: determining the 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;

[0049] Step S220: adjusting the target road model unit corresponding to each curve segment based on the road form parameter corresponding to each curve segment.

[0050] The road type parameter refers to a configuration parameter for a road model unit type. For example, one of a straight road, a road with a cross, one of an 8-lane road, a 6-lane road, and a 4-lane road, one of a general road, a tunnel, an elevated road, and a ramp, and the like.

[0051] For example, the road type parameter corresponding to each curve segment can be read and compared with the configuration file of the candidate road model unit to be stored, so that the target road model unit matching the road type parameter of each curve segment is determined.

[0052] After the target road model unit matching the road type parameter of each curve segment is determined, the target road model unit can be further adjusted to improve the splicing effect between the target road model units.

[0053] The road shape parameter refers to a control parameter that can affect the shape of the road, such as the width, length, height, and curvature of the road. The target road model unit corresponding to each curve segment is adjusted according to the road shape parameter corresponding to each curve segment, so that the target road model unit can better adapt to the road control curve.

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

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

[0056] Figure 2 The step in the above embodiment realizes the adjustment of the target road model unit from the curve segment level, and 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 configured with a node control parameter, and the target road model unit corresponding to each curve segment is adjusted by the following step: adjusting the target road model unit corresponding to each curve segment according to the node control parameter corresponding to each control point.

[0058] The node control parameter refers to a control parameter defined in advance at the node level for controlling the shape of the road model.

[0059] Optionally, a road width parameter, a road height parameter, a road curvature parameter, etc. can be defined in the node control parameter, so as to adjust the target road model unit corresponding to each curve segment from the node level, so as to improve the editing accuracy of the virtual road. It should be noted that in actual application, some road control parameters can be set at the node level, the curve segment level, or the whole level. Different levels of setting will result in different performance accuracy of the virtual road. For example, the road width parameter, the road height parameter, the road curvature parameter, etc. can be customized according to actual needs, and the present disclosure does not make specific limitations. The user can customize the road control parameters at different levels to achieve higher controllability of the generation of the virtual road.

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

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

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

[0063] The overall control parameter refers to a control parameter defined at the overall level for controlling the shape of the road model. For example, the overall control parameter can define the road material, such as asphalt road, concrete road, etc., which is not limited in the present disclosure.

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

[0065] Adjusting the target road model unit by the control parameters at different levels can ensure the generation quality of the virtual road to a certain extent while ensuring the convenience of user editing.

[0066] In an optional embodiment, after the road control curve is obtained, the following steps can be further performed: determining a curve intersection point between each curve segment, and judging whether an included angle between the curve segments connected with the curve intersection point satisfies a preset condition; if not, adjusting the included angle between the curve segments connected with the curve intersection point so as to make the included angle satisfy the preset condition.

[0067] For example, the curve intersection point refers to a control point connected with at least three curve segments, i.e. a point where there is a fork in the road control curve, and is a subset of control points.

[0068] The preset condition refers to a condition preset for adjusting the curve intersection angle. By setting the preset condition, the curve intersection angle can be normalized to determine a target road model unit that fits well from the candidate road model units.

[0069] In an optional embodiment, whether the included angle between the curve segments connected with the curve intersection point satisfies the preset condition can be determined by judging whether the included angle between the curve segments connected with the curve intersection point belongs to a subset of a preset included angle set.

[0070] The preset included angle set refers to a set of one or more normalized included angles, such as a 30-degree included angle, a 45-degree included angle, a 90-degree included angle, etc., which can correspond to the road model unit related to the intersection angle in the candidate road model unit to normalize the fork included angle and increase the fitting degree between the road model unit and the curve.

[0071] For example, whether the included angle between the curve segments connected with the curve intersection point belongs to a subset of a preset included angle set can be determined. If yes, it is considered that the preset condition is satisfied; if no, it is considered that the preset condition is not satisfied.

[0072] If the included angle between the curve segments connected with the curve intersection point satisfies the preset condition, the included angle between the curve segments connected with the curve intersection point can not be adjusted.

[0073] If the included angle between the curve segments connected with the curve intersection point does not satisfy the preset condition, the included angle between the curve segments connected with the curve intersection point can be adjusted.

[0074] For example, as shown in FIG. 4, a flowchart for adjusting the included angle is provided, which can include the following steps: Figure 3

[0075] Step S301, determining the curve intersection points between the curve segments;

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

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

[0078] Step S304, adjusting the included angle between the curve segments connected with the curve intersection point to make the included angle belong to a subset of a preset included angle set.​

[0079] In an optional implementation, the adjustment of the included angle between the curve segments connected with the curve intersection point to meet the preset condition can be achieved by the following steps: determining the included angle difference between the included angle between the curve segments connected with the curve intersection point and each included angle in the preset included angle set; determining a target included angle from the preset included angle set according to the included angle difference; and adjusting the included angle between the curve segments connected with the curve intersection point according to the target included angle.

[0080] For example, the included angle difference between the included angle between the curve segments connected with the curve intersection point and each included angle in the preset included angle set can be determined, the included angle with the smallest included angle difference in the preset included angle set can be selected as the target included angle, and the included angle between the curve segments connected with the curve intersection point can be adjusted to the target included angle to standardize the fork included angle.

[0081] In an optional implementation, the adjustment of the target road model unit corresponding to the curve segments connected with the curve intersection point according to the intersection control parameter can be achieved by the following steps: adjusting the target road model unit corresponding to the curve segments connected with the curve intersection point according to the intersection control parameter.

[0082] The intersection control parameter refers to a parameter set at the curve intersection point level for controlling the connection of the fork road, which can realize flexible editing of the fork road and further enhance the controllability of road generation. For example, the intersection control parameter can define a width control parameter, a rotation control parameter, and the like.

[0083] In an optional implementation, the adjustment of the target road model unit corresponding to the curve segments connected with the curve intersection point according to the intersection control parameter can be achieved by the following steps: performing scaling processing on the target road model unit corresponding to the curve segments connected with the curve intersection point according to the width control parameter in the intersection control parameter; and / or performing rotation processing on the target road model unit corresponding to the curve segments connected with the curve intersection point according to the rotation control parameter in the intersection control parameter.

[0084] For example, the scaling processing on the target road model unit corresponding to the curve segments connected with the curve intersection point according to the width control parameter in the intersection control parameter can be overall scaling of the target road model unit, or can be scaling of only the connection end of the target road model unit, which is not limited in the present disclosure.

[0085] Exemplarily, when the target road model unit corresponding to the curve segment connected with the intersection point of the curve is rotated according to the rotation control parameter in the intersection control parameter, the orientation of the target road model unit is adjusted, and different placement scenarios of the target road model unit can be flexibly met.

[0086] In step S130, the target road model units corresponding to the curve segments are spliced according to the positions of the curve segments in the road control curve, and a virtual road matching the road control curve is obtained.

[0087] Specifically, the target road model units corresponding to the curve segments can be spliced in sequence according to the positions of the curve segments in the road control curve, and a virtual road matching the road control curve is obtained.

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

[0089] Exemplarily, as shown in Figure 4 A flowchart for generating a virtual road based on a road control curve is provided, and the flowchart can include the following steps:

[0090] In step S401, a road control curve is obtained, and the road control curve is configured with overall control parameters; the road control curve is composed of a plurality of curve segments, and each curve segment is configured with segment control parameters; each curve segment is composed of at least two control points, and each control point is configured with node control parameters;

[0091] In step S402, the target road model units corresponding to the curve segments are determined from the candidate road model units according to the road type parameters in the segment control parameters corresponding to the curve segments;

[0092] In step S403, the target road model units corresponding to the curve segments are adjusted according to the overall control parameters, the node control parameters of the control points, and the road shape parameters in the segment control parameters corresponding to the curve segments.

[0093] In step S404, the target road model units corresponding to the curve segments are spliced according to the positions of the curve segments in the road control curve, and a virtual road matching the road control curve is obtained.

[0094] Figure 4In the illustrated step, by dividing different levels, the attribute configuration of the road control curve is subdivided, so that the control accuracy of the virtual road reaches each curve segment or even each control point, instead of the entire curve, without relying on the fixed value of the internal algorithm of the tool, and the diversification and controllability of the virtual road performance can be improved.

[0095] The exemplary embodiments of the present disclosure also provide a virtual road generation device, which refers to Figure 5 As shown, the virtual road generation device 500 can include the following program modules:

[0108] The specific details of each part of the above apparatus have been described in detail in the method part implementation, and the undisclosed details can be referred to the implementation content of the method part, and thus will not be described again.

[0115] According to the segment control parameter corresponding to each curve segment, determining the target road model unit corresponding to each curve segment from the candidate road model unit, and adjusting the target road model unit corresponding to each curve segment;

[0116] According to positions of the curve segments in the road control curve, the target road model units corresponding to the curve segments are spliced to obtain a virtual road matching the road control curve.

[0117] In an alternative implementation, based on the foregoing scheme, after the road control curve is obtained, the following step can be further performed: smoothing each curve segment in the road control curve to obtain an adjusted curve segment.
