[0062] Next, Figure 1 Taking the electronic device 1000 as an example of an implementation subject, various embodiments of the method for constructing a virtual scene are described.

[0063] <First Embodiment>

[0064] Figure 2 A method for constructing a virtual scene according to some embodiments is shown. The method for constructing a virtual scene may include the following steps S210 to S250:

[0065] Step S210: determining a first attribute of each scene plane in the virtual scene based on a first input from a user.

[0066] In this embodiment, the virtual scene can be constructed based on three-dimensional computer image software such as Houdini, Maya, Cinema 4D, etc.

[0067] In this embodiment, the virtual scene may be composed of multiple scene planes, such as a 50×50 scene plane, a 100×200 scene plane, or a 500×1000 scene plane. In addition, each scene plane in the virtual scene has a first attribute, which can be divided into an interactive attribute corresponding to an interactive object and a connection attribute corresponding to an interactive object. When the first attribute of a scene plane is an interactive attribute, the scene plane can be interactively operated by the player. For example, if the first attribute of scene plane A1 is an interactive attribute, then the player's virtual character can move to the scene plane A1. When the first attribute of a scene plane is a connection attribute, the scene plane is the plane where at least a part of a decoration or obstacle is located. For example, if the first attribute of scene plane A2 is a connection attribute and the scene plane A2 is the plane where a part of the decoration is located, then the player's virtual character can only pass through the scene plane A2.

[0068] Step S220: determining, according to the first attribute, an interactive area corresponding to the interactive object in the virtual scene and a connection area corresponding to the connection object in the virtual scene.

[0069] In some examples, such as Figure 3 As shown, the interactive object is a plot of land, then the interactive area corresponding to one of the interactive objects is, for example, the interactive area LT, and the connection object is a mountain, and the connection area corresponding to one of the connection objects is, for example, the connection area R1.

[0070] Step S230: setting the interactive area to an interactive unit that meets the set conditions.

[0071] In some embodiments, in order to maintain the occupied space of the virtual scene within a reasonable range, the set condition includes at least one of the number of interaction units being within a set number range and the area of ​​the interaction units being within a set area range.

[0072] In this embodiment, the set number range is, for example, 30-50, 100-120 or 200-300, and the set area range is, for example, 2-5 scene planes, 5-8 scene planes or 10-15 scene planes.

[0073] In some examples, for the interaction area to be split into interaction units within a set number range, a preset Python processing script can be used, which can automatically adjust the parameters of the interaction area Cluster node and keep the number of effective blocks of the interaction area Cluster at 100, that is, the interaction area is split into 100 blocks. The automatic adjustment parameters here are generally adjusted by determining the seed and the step.

[0074] In some examples, the interaction area is split into interaction units within a set number range, specifically: 3.1 Use the null node as the node for external Python to get attributes; 3.2 Use the attribdelete node to delete unnecessary attributes; 3.3 Use the clusterpoints node to split the interaction area into interaction units; 3.4 Use the attribtransfer1 node to transfer necessary attributes for subsequent operations; 3.5 Use the split node, attribwrangle1 node, and attribwrangle2 node to separate the connection area from the interaction unit and count the number of blocks, and Python checks whether it can be output; 3.6 Use the blast node to remove mountains and rivers, and use the attribtransfer node to transfer the attribute data of the interaction unit to the original interaction area and output it.

[0075] Step S240, fitting the edge line of the interaction unit and the trend line of the connection area to obtain a fitting boundary line.

[0076] In this embodiment, the trend line of the connection area can be the center line of the connection area, and the fitting boundary line can be a specific line between the edge line and the trend line, and the first relative distance between the specific line and the edge line is equal to or in a certain proportion to the second relative distance between the specific line and the trend line.

[0077] Step S250, constructing a virtual scene according to the interactive units, the connection areas and the fitted boundary lines.

[0078] In this embodiment, the interactive units and the connection areas are merged according to the fitted boundary lines to construct a virtual scene.

[0079] According to the method for constructing a virtual scene of the first embodiment of the present invention, the problem of low construction efficiency in the prior art of constructing a virtual scene by artificially dividing blocks is solved. Based on this method, the first attribute of each scene plane in the virtual scene can be determined according to the first input of the user, and the interaction area of ​​the interactive object and the connection area of ​​the connection object in the virtual scene can be determined according to the first attribute. Then the interaction area is split into interaction units that meet the conditions, the edge line of the interaction unit and the trend line of the connection area are fitted to obtain a fitting boundary line, and the interaction area and the connection area are merged according to the fitting boundary line to construct a virtual scene. In other words, through the user's simple parameter adjustment or instruction information, the interaction area and the connection area in the virtual scene are roughly screened out, and then the interaction area is split into multiple interaction units that can be operated by the user, and the edges of each interaction unit and the adjacent connection area are fitted into a fitting boundary line, thereby realizing the rapid construction of the virtual scene, and effectively improving the construction efficiency of the virtual scene. .

[0080] <Second Embodiment>

[0081] In this embodiment, in order to improve the processing effect of determining the first attribute of each scene plane, the first input includes a feature map, through which the attribute information of the interactive object and the connection object is set in the same feature map, so that the fourth attribute of the interactive object and the fifth attribute of the connection object can be determined.

[0082] In these embodiments, relative to the first embodiment, before step S220, the method further includes the following steps S310 to S340:

[0083] Step S310: extracting a second attribute in a first color channel of the feature map and a third attribute in a second color channel of the feature map based on the feature map input by the user.

[0084] In this embodiment, the feature map is, for example, a mask image, the first color channel of the feature map is, for example, an R channel of the mask image, and the second color channel of the feature map is, for example, a G channel of the mask image.

[0085] Step S320: Determine that the second attribute is mapped to a fourth attribute of the interactive object in the virtual scene.

[0086] In this embodiment, the second attribute is, for example, a value between 0 and 1, and the fourth attribute is, for example, a value between 0 and 255 and represents a color.

[0087] Step S330, writing the third attribute into the virtual scene, and obtaining the fifth attribute of the connection object in the virtual scene.

[0088] In this embodiment, the third attribute of the second color channel of the feature map is written into the point attribute of the grid of the virtual scene, and this attribute is named Mountain, River, that is, the fifth attribute.

[0089] Step S340: Obtain the first attribute of each scene plane in the virtual scene according to the fourth attribute and the fifth attribute.

[0090] In some examples, to obtain the first attribute of each scene plane in the virtual scene, it can be: 1.1 Use the grid node to provide a carrier for subsequent calculations; 1.2 Use the attrib from map node to write the information of the R channel in the mask image into the point attribute of the grid, and name this attribute Land; 1.3 Use the attrib wrangle node to map the value range of the second attribute to the value range of the fourth attribute, that is, the numerical space of 0-1 is mapped to the color space of 0-255. 1.4 Use the attrib promote node to transform the second attribute from a point-level attribute to a Primitive-level attribute. 1.5 Use the blast node to delete the primitives with Land < 1.1 to obtain the polygon structure corresponding to the R channel in the mask image. 1.6 Use a for loop to traverse all primitives and clean up the erroneous primitive data caused by pixel errors; 1.7 Use the attrib promote node to transform the second attribute from a surface-level attribute to a Detail-level attribute. 1.8 Use the attrib wrangle node to align the second attribute with the color scale map number; 1.9 Use the attribute node to rename the second attribute to ToPython, which will be used as the number of loops in the subsequent python script; 1.10 Use the SinglePass node of foreach to traverse each interaction area, processing only one interaction area at a time. 1.11 Use the grid3 and grid4 nodes to provide a carrier for subsequent calculations; 1.12 Use the attrib rom map3 and attrib from map4 nodes to write the information of the G channel in the mask image into the point attribute of the grid, and name this attribute Mountain, River. 1.13 Use the attribtranster1 and attribtranster2 nodes to transfer the attributes to the current interaction area; 1.14 Use the attrib promote node to promote the Mountain and River attributes to the surface.

[0091] <Third Embodiment>

[0092] In this embodiment, in order to reduce the existence of small surfaces in the virtual scene and ensure that the area of ​​each interactive unit is moderate, small surfaces with different attribute types and scene planes can be merged to obtain interactive areas and connection areas with moderate areas.

[0093] In these embodiments, relative to the first embodiment, step S220 may include the following steps S410 to S440:

[0094] Step S410 , in each scene plane, select a first small surface whose first attribute corresponds to a first attribute type and a first scene plane whose first attribute corresponds to a second attribute type.

[0095] In some examples, the first attribute type is a mountain river type, and the second attribute type is a land surface type.

[0096] Step S420: merge the first small surface and the first scene plane and use them as the interaction area corresponding to the interaction object in the virtual scene.

[0097] Step S430: In each scene plane, select a second small surface whose first attribute corresponds to a second attribute type and a second scene plane whose first attribute corresponds to a first attribute type.

[0098] Step S440: merge the second small surface and the second scene plane and use them as the connection area corresponding to the connection object.

[0099] In some examples, for the first small face and the first scene plane to be merged and the second small face and the second scene plane to be merged, it can be: 2.1 Use the distance_from_border1 node to take a value from 1 to 0 from the model center to the edge of the interaction area; 2.2 Use the group node to mark the edge points; 2.3 Use the attributeWrangle node to clear the Mountain and River attributes of the marked edge points; 2.4 Use the Split node to separate the faces with mountain attributes from those without mountain attributes; 2.5 Use the Split node to separate the faces with River attributes from those without River attributes; 2.6 Use the merge node to merge the faces with River and Mountain attributes into one level; 2.7 Use the remove unconnectedpoints1 node to remove a single point that does not intersect any face; 2.8 Use the delete small face node to remove the single point that does not intersect any face; The parts1 node marks the first small face in the face with mountain and river attributes; 2.9.
