The game scene also comprises virtual vegetation models such as trees, shrubs, grass clusters, flowers clusters and the like. The normal direction of the virtual vegetation model may be the first direction (may be expressed in a vector form) described above. The virtual natural landscape (e.g., frost, snow, etc.) may be overlaid on the virtual vegetation model. The direction of coverage of the virtual vegetation model by the virtual natural landscape may be the above-described second direction (may be expressed in a vector form).
And determining the first coverage range of the virtual natural landscape by adopting the normal direction of the virtual vegetation model and the coverage direction of the virtual natural landscape to the virtual vegetation model in the game scene. The first coverage area is used for rendering the virtual natural landscape on the virtual vegetation model.
Step S22, determining thickness information of the virtual natural landscape based on the first coverage area and the second direction;
and determining thickness information of the virtual natural landscape based on the first coverage area and the coverage direction of the virtual natural landscape to the virtual vegetation model. For example, the thickness information may be the thickness of a virtual snow model overlaid on the virtual vegetation model.
Step S23, performing transition processing on the first mapping and the second mapping through the first coverage area to obtain a processing result, wherein the first mapping is a primary color mapping of the virtual natural landscape, and the second mapping is a normal mapping of the virtual natural landscape;
The first map is used for determining the rendering color of the virtual natural landscape, and is a primary color map of the virtual natural landscape. The second mapping is used for determining three-dimensional detail textures of the virtual natural landscape, and the second mapping is a normal mapping of the virtual natural landscape.
And performing transition processing on the primary color map and the normal map of the virtual natural landscape through the first coverage area to obtain the processing result. The result of this process may be a new hybrid map.
And step S24, rendering the virtual natural landscape on the virtual vegetation model by using the thickness information, the first coverage area and the processing result.
And rendering the virtual natural landscape on the virtual vegetation model by using the thickness information of the virtual natural landscape, the first coverage of the virtual natural landscape on the virtual vegetation model and the processing result.
It is easy to understand that, according to the method for rendering a virtual natural landscape provided in the above steps S21 to S24 of the present application, the background map of the natural landscape to be rendered does not need to be modified manually, and the virtual natural landscape is rendered by using the normal direction of the virtual vegetation model in the game scene and the coverage direction of the virtual natural landscape to the virtual vegetation model based on the primary color map and the normal map of the virtual natural landscape.
In at least some embodiments of the present application, a first coverage area of a virtual natural landscape is determined by using a first direction and a second direction, where the first direction is a normal direction of a virtual vegetation model in a game scene, the second direction is a coverage direction of the virtual natural landscape on the virtual vegetation model, thickness information of the virtual natural landscape is determined based on the first coverage area and the second direction, and further, transition processing is performed on the first map and the second map through the first coverage area to obtain a processing result, where the first map is a primary color map of the virtual natural landscape, and the second map is a normal map of the virtual natural landscape, and the virtual natural landscape is rendered on the virtual vegetation model by using the thickness information, the first coverage area and the processing result, so that a purpose of rendering the virtual natural landscape on the virtual vegetation model at a lower cost is achieved, and a technical effect of reducing performance consumption of the virtual natural landscape on the virtual preparation model and improving flexibility and reusability of a rendering process is achieved, and further, a technical problem of a virtual natural landscape rendering method provided in a related technology is solved that performance consumption is large, rendering flexibility and reusability is poor.
The above-described methods of embodiments of the present application are further described below.
Optionally, in step S21, determining the first coverage of the virtual natural landscape using the first direction and the second direction may include performing the steps of:
step S211, obtaining an included angle relation between the first direction and the second direction;
step S211, determining the first coverage area based on the angle relation.
The relationship between the first direction and the second direction may include: perpendicular, parallel, and other angular relationships. The specific mode for determining the first coverage area based on the included angle relation is as follows: determining a region with an included angle relation between the normal direction (namely a first direction) of the virtual vegetation model and the covering direction (namely a second direction) of the virtual natural landscape to the virtual vegetation model as a vertical relation as a range which is not required to be covered; determining an area with an included angle relation between the normal direction of the virtual vegetation model and the covering direction of the virtual natural landscape on the virtual vegetation model as a parallel relation as a range to be covered; calculating a range to be covered in an area with an included angle relation between the normal direction of the virtual vegetation model and the covering direction of the virtual natural landscape on the virtual vegetation model as other angle relations by utilizing a pre-designated parameter; and further determining all the coverage areas required to be covered on the surface of the virtual vegetation model as the first coverage area.
The method for rendering the virtual natural landscape can be applied to scenes related to virtual natural landscape rendering in the fields of electronic games, virtual reality and the like. The method is particularly suitable for a scene of rendering a virtual natural landscape (such as a snow accumulating layer) on a virtual vegetation model in an electronic game scene, and the technical scheme provided by the embodiment of the application is further described by taking the scene as an example.
In the video game scene, under the scene of rendering the snow accumulation layer on the virtual vegetation model, firstly, the normal direction (corresponding to the first direction) of the virtual vegetation model and the covering direction (corresponding to the second direction) of the snow accumulation layer on the virtual vegetation model are obtained, and the included angle relation between the normal direction of the virtual vegetation model and the covering direction of the snow accumulation layer on the virtual vegetation model is determined. And determining the first coverage area based on the included angle relation, wherein the first coverage area is a to-be-rendered area of the snow covered on the surface of the virtual vegetation model.
Fig. 3 is a schematic view of an alternative coverage area of snow on a vegetation surface according to an embodiment of the present application, and fig. 3 is a cross-sectional view of a tree model covered with snow layers, and according to a normal direction of the tree model and a coverage direction of the snow layers on the data model, an area corresponding to a black line segment shown in fig. 3 may be determined as a coverage area where snow needs to be covered (corresponding to the first coverage area described above).
Optionally, the virtual vegetation model comprises: a virtual trunk model and a virtual branch model, the first direction comprising: in step S211, obtaining the relationship between the trunk normal direction of the virtual trunk model and the branch normal direction of the virtual branch model may include the following steps:
step S2111, performing point multiplication calculation on the main trunk normal direction and the second direction to obtain a first calculation result;
step S2112, converting the branch normal direction from tangent space to world space to obtain a conversion result;
step S2113, performing dot product calculation on the conversion result and the second direction to obtain a second calculation result;
step S2114, determining an angle relationship based on the first calculation result and the second calculation result.
Still taking the example of rendering a snowlayer on a virtual vegetation model in an electronic game scene, the virtual vegetation model comprises a virtual trunk model and a virtual branch model, and accordingly, the normal direction (corresponding to the first direction) of the virtual vegetation model comprises the trunk normal direction of the virtual trunk model and the branch normal direction of the virtual branch model.
And performing point multiplication calculation on the normal direction (corresponding to the first direction) of the virtual vegetation model and the coverage direction (corresponding to the second direction) of the virtual natural landscape to obtain the included angle relation between the first direction and the second direction.
For example, the virtual tree model includes a trunk model and a branch model (including a leaf model). When the snow layer is rendered on the virtual tree model, the trunk part and the branch part can be respectively calculated and rendered.
Specifically, the branch part of the virtual vegetation model is usually realized through the plug-in board, so when the virtual natural landscape is rendered on the branch part, the normal line of the branch part is required to be converted from the tangent space to the world space, and then the normal line of the branch part and the virtual natural landscape are subjected to dot multiplication calculation on the covering direction of the branch part, so that the second calculation result is obtained. The trunk part of the virtual vegetation model usually does not need to undergo space conversion of the normal line, and the normal line of the branch part and the virtual natural landscape directly carry out dot product calculation on the coverage direction of the trunk part to obtain the first calculation result.
And determining the relation of the included angle between the normal direction of the virtual vegetation model and the coverage direction of the virtual natural landscape to the virtual vegetation model through the first calculation result and the second calculation result.
According to the relation of the included angles between the first direction and the second direction, for a certain point on the surface of the virtual vegetation model: when the first direction is perpendicular to the second direction, the point is not covered with the snow accumulating layer at all; when the first direction is parallel to the second direction, the point completely covers the snow accumulation layer; when the first direction and the second direction are in other angle relations, the snow covering degree of the point is determined according to the point multiplication result of the first direction and the second direction.
Alternatively, in step S22, determining thickness information of the virtual natural landscape based on the first coverage and the second direction may include performing the steps of:
step S221, performing offset processing on the model vertexes of the virtual vegetation model based on the first coverage area and the second direction to obtain offset distances of the model vertexes;
in step S222, thickness information is determined using the offset distance.
The thickness information can be used for determining the offset degree of the model vertex of the virtual vegetation model, and the thickness value corresponding to the thickness information is larger as the offset degree is higher.
Still taking the example of rendering a snowlayer on a virtual vegetation model in an electronic game scene, the coverage (corresponding to the first coverage) and the coverage direction (corresponding to the second direction) of the virtual vegetation model by utilizing the virtual natural landscape are utilized to offset the model vertexes of the virtual vegetation model, so as to obtain the offset distance of the model vertexes. The offset distance is further used to determine the thickness of the snowy layer.
It should be noted that, a specific implementation manner of performing offset processing on the model vertices of the virtual vegetation model may be: and shifting the model vertexes of the virtual vegetation model to a new set of positions, or generating a new set of model vertexes based on the model vertexes of the virtual vegetation model and the second direction.
It is easy to understand that the thickness of the snow cover layer is obtained by performing offset processing on the model fixed points of the virtual vegetation model, so that the snow cover layer obtained by rendering can be ensured to have a better virtual vegetation coverage effect (for example, the surface shape of the snow cover layer corresponds to the surface shape of the virtual vegetation model covered by the snow cover layer).
Optionally, in step S23, the transition processing is performed on the first map and the second map through the first coverage area, and determining the processing result may include the following execution steps:
in step S231, a third mapping is used to perform transition processing on the first mapping and the second mapping in the boundary area between the virtual natural landscape and the virtual vegetation model through the first coverage area, and a processing result is determined, where the third mapping is a preset noise mapping.
Still taking the example of rendering a snow accumulation layer on a virtual vegetation model in an electronic game scene, sampling a primary color map and a normal map of a virtual natural landscape based on the coverage (equivalent to the first coverage) of the virtual vegetation model by the snow accumulation layer, and performing transition processing on a boundary area between the primary color map and the normal map by using a preset noise map to obtain a processing result.

Based on the area (corresponding to the first coverage area) where the surface of the virtual vegetation model needs to be covered with snow, the noise map shown in fig. 6 is used to perform transition processing on the primary color map shown in fig. 4 and the normal line map shown in fig. 5, and the processing result is determined. The processing result is used for determining that the junction between the area needing to be covered with the snow layer and the area not needing to be covered with the snow layer on the surface of the virtual vegetation model has a gradual change effect of noise patterns.
Therefore, in the area with a far angle from the coverage direction (namely the second direction) on the surface of the virtual vegetation model, the influence of the noise mapping is larger, so that the junction between the area needing to be covered with the snow layer and the area not needing to be covered with the snow layer on the surface of the virtual vegetation model has a gradual change effect of noise patterns, and the reality of the virtual natural landscape in the virtual scene is further improved.
Optionally, in step S24, rendering the virtual natural landscape on the virtual vegetation model using the thickness information, the first coverage, and the processing result may include performing the steps of:
step S241, mixing the first coverage area and the processing result to obtain a second coverage area;

Still taking the example of rendering a snow accumulation layer on a virtual vegetation model in an electronic game scene, mixing the processing result onto the surface of the virtual vegetation model within the coverage range of the snow accumulation layer to the virtual vegetation model to obtain the second coverage range. The above mixing process may utilize specified parameters to control the coverage (i.e., mixing range) and mixing intensity. And further rendering the snow layer on the virtual vegetation model based on the second coverage area and the thickness of the snow layer.
Specifically, the range of the snow layer to be covered on the virtual vegetation model is still utilized, the noise map as shown in fig. 6 is used as a weight, and the primary color map and the normal line map after the transition processing are subjected to linear interpolation, so that the second coverage range is obtained. The above linear interpolation can be expressed as Lerp (original color of the virtual vegetation model, snow color, noise figure).
It should be noted that, in the process of mixing the first coverage area and the processing result, parameters may be used to control the range of the snow layer to be covered on the virtual vegetation model. For example, the dot product results in the first direction and the second direction are controlled by interpolation results Lerp (full coverage area, full no coverage area, dot product result); control by a function Step (dot product, x), "when the dot product is not greater than x, the dot product is set to 0 (corresponding to no coverage at all)"; the curve of the dot product function is controlled by the parameter y (for example, the slope of the function is changed by the dot product multiplied by y, and the snow layer is controlled to be faster or slower according to the change degree of the included angle between the first direction and the second direction by setting the value of y).
Optionally, in step S242, rendering the virtual natural landscape on the virtual vegetation model based on the thickness information and the second coverage may include performing the steps of:
step S2421, determining a third coverage area by utilizing the second coverage area and the partial area to be removed, wherein the partial area to be removed is an area which is not covered by the virtual natural landscape in the virtual vegetation model;
step S2422, rendering the virtual natural landscape on the virtual vegetation model based on the thickness information and the third coverage.
After the foregoing processing in the foregoing steps of this embodiment, the second coverage area may still include an area (corresponding to the to-be-removed partial area) that is not covered by the virtual natural landscape in the virtual vegetation model, and the second coverage area and the to-be-removed partial area are used to determine a third coverage area. And rendering the snow layer on the virtual vegetation model based on the thickness of the snow layer and the third coverage area.
Optionally, in step S2421, determining the third coverage using the second coverage and the partial region to be culled may include performing the steps of:
step S2423, determining a partial region to be removed from the second coverage area by adopting a global mask drawing mode;
step S2424, the partial region to be removed is removed from the second coverage area, so as to obtain a third coverage area.
The global mask drawing method may be that a second coverage area is identified and drawn by a pre-set Shader (loader) code, and an area (corresponding to the partial area to be removed) that is not covered by the virtual natural landscape in the virtual vegetation model is determined from the second coverage area. And removing the partial area to be removed from the second coverage area to obtain a third coverage area, wherein the third coverage area is the range to be used for rendering the virtual landscape model on the virtual vegetation model. Therefore, the area, which needs to be covered by the snow layer, of the surface of the virtual vegetation model can be further accurately determined, and the rendering fidelity of the virtual natural landscape on the virtual vegetation model is improved.
Illustratively, the region that needs to be determined as the partial region to be culled by the above-described global mask drawing method is as follows: areas where the trunk portion of the vegetation is normal upward, areas in the trunk portion that are obscured by its leaves, and the like.
Through the method provided by the embodiment of the application, a general method for rendering the virtual natural landscape on the virtual vegetation model can be realized by using a Shader (such as a loader) code, and the virtual natural landscape rendering effect (such as coverage degree, coverage range and coverage direction of the virtual natural landscape on the virtual vegetation model, primary color mapping, normal mapping and the like of the virtual natural landscape) on the virtual vegetation model can be dynamically controlled by parameters, and the parameters can be coupled with other systems (such as a weather system, a time system and the like) in a game engine, so that the reusability and the flexibility are high.
