In one possible implementation, an embodiment of the present application provides an information processing method. Fig. 2 is a flowchart of an information processing method according to an embodiment of the present application, and as shown in fig. 2, the method includes the steps of:

step S202, determining a scene area of the virtual scene and outline information of the virtual character in the virtual scene.

In the technical solution provided in the foregoing step S202 of the present application, a scene area of a virtual scene and contour information of a virtual character in the virtual scene are determined, where the virtual scene may be a game scene, the scene area may be an area in the virtual scene that needs a baking depth map, the virtual character may be a virtual game character that is controlled by a player through a terminal device in the virtual scene, that is, a controlled virtual object in the virtual scene, and the contour information may be used to represent a geometric space enclosing the virtual character, for example, an enclosure (bounding boxes), and is not specifically limited herein.

Step S204, dividing the scene area based on the outline information to obtain a plurality of sub-scene areas.

In the technical solution provided in step S204 above, a dividing parameter may be obtained by dividing the volume of a scene area of a virtual scene by the contour information of a virtual character and rounding, and then the scene area is divided by using the dividing parameter to obtain a plurality of sub-scene areas, where the sub-scene areas may be partitioned areas of the virtual scene, for example, small rectangular solid areas (cells).

Optionally, the outline of each sub-scene region is larger than the outline of the virtual character, that is, the volume of each sub-scene region obtained by dividing the scene region may be larger than the volume of the virtual character, so as to avoid the situation that the boundary of the sub-scene region crosses the body of the virtual character, for example, the situation that the upper half of the virtual character in the scene region a and the lower half of the virtual character in the scene region B cannot occur.

Optionally, the contour information of the virtual character may also be adjusted according to the motion amplitude of the virtual character in the virtual scene, for example, the side length of the bounding box of the virtual character is adjusted to obtain the side length of the bounding box of the sub-scene region, the side length of the bounding box of the sub-scene region is determined as a division parameter, and then the scene region is divided by using the division parameter to obtain a plurality of sub-scene regions.

Optionally, after the scene area is divided according to the division parameters to obtain a plurality of sub-scene areas, an area position of each sub-scene area in the virtual scene, a position of the depth camera corresponding to each sub-scene area, and an identifier of each sub-scene area may be further determined, for example, the identifier may be an Identity document (Id), where the area position of each sub-scene area is uniquely identified by Id, and the area position of the corresponding sub-scene area may be determined by Id.

Optionally, the corresponding relationship between the Id of the sub-scene region and the virtual object included in the sub-scene region may be stored as list data in a Key-Value pair (Key-Value) manner, and the corresponding virtual object may be directly called from the list data by the Id of the sub-scene region.

Step S206, baking the first virtual object included in the sub-scene region to obtain a first depth map of the first virtual object.

In the technical solution provided in the above step S206 of the present application, the first virtual objects included in the sub-scene area are respectively baked by the depth camera to obtain a plurality of first depth maps of the first virtual objects, and the shadow effect is implemented on the virtual character in the virtual scene by the plurality of first depth maps, where the first virtual object may be an object included in the sub-scene area and generating a shadow on the virtual character, and may be an object that is stationary in the sub-scene area, for example, an object that is stationary in the sub-scene area, such as a window, a vase, and the like, which is only illustrated by way of example and is not limited specifically.

Optionally, the shooting area of the sub-scene area by the depth camera may be determined according to the volume of the bounding box of the sub-scene area, and in order to ensure that the virtual character does not exceed the sub-scene area division boundary in the motion state, the shooting area of the depth camera needs to be larger than the volume of the bounding box of the virtual character in the sub-scene area, that is, the sub-scene area needs to be located within the shooting area of the depth camera, for example, the volume of the bounding box of the sub-scene area, root 2, is determined as the shooting area of the depth camera in the virtual scene, which is only an example and is not limited specifically herein.

Alternatively, if a dynamic object appears in the sub-scene area, the first virtual object may be directly called from the list data through the Id of the sub-scene area, so that the depth camera only needs to capture the depth maps of the first virtual object and the dynamic object on the shooting area, create the depth maps as shadow maps, and render and display the shadow generated by the dynamic object and the first virtual object on the virtual character based on the shadow maps, thereby achieving the purpose that the dynamic object only causes the shadow effect on the virtual character, but does not cause the shadow effect on other scene objects (e.g., a floor).

In step S208, a first shadow map is created by using the first depth map.

In the technical solution provided by the foregoing step S208 in the present application, a first shadow map is created based on a first depth map obtained by a depth camera shooting a first virtual object in a sub-scene area, where the first shadow map may be used to render and display a shadow generated by the first virtual object on a virtual character.

Step S210, the first target shadow representation is rendered and displayed on the virtual character based on the first shadow map.

In the technical solution provided in the above step S210 of the present application, a first target shadow representation is rendered and displayed on the virtual character through the created first shadow map, where the first target shadow representation may be a shadow display effect formed by the first virtual object on the virtual character, for example, a shadow display effect generated by a window on the virtual character.

Determining a scene area of a virtual scene and outline information of a virtual character in the virtual scene through the steps S202 to S210; dividing the scene area based on the outline information to obtain a plurality of sub-scene areas, wherein the outline of each sub-scene area is larger than the outline of the virtual role; baking a first virtual object contained in the sub-scene area to obtain a first depth map of the first virtual object; creating a first shadow map using the first depth map; and rendering and displaying a first target shadow expression on the virtual character based on the first shadow map, wherein the first target shadow expression is a shadow formed by the first virtual object to the virtual character. That is to say, the embodiment of the present application implements a method for dividing a scene area, in which a virtual character in a virtual scene can be baked in a manner of a sub-scene area to generate a depth map by dividing the scene area into a plurality of sub-scene areas, a shadow map is created based on the depth map, and a corresponding shadow map is rendered on the virtual character to display a shadow representation, so as to achieve the purpose of ensuring the accuracy requirement of the depth map and not causing shadows to other scene objects, thereby solving the technical problem that a shadow effect that meets the requirement of the virtual scene cannot be achieved, and achieving the technical effect of achieving the shadow effect that meets the requirement of the virtual scene.

The above method of this embodiment is further described below.

As an optional implementation manner, in step S204, dividing the scene area based on the contour information to obtain a plurality of sub-scene areas, including: determining a division parameter based on the outline information of the virtual role; and dividing the scene area according to the dividing parameters to obtain a plurality of sub-scene areas.

In this embodiment, the dividing parameter may be obtained by dividing the volume of the scene area of the virtual scene by the contour information of the virtual character and rounding, and then dividing (Split) the scene area by using the dividing parameter to obtain a plurality of sub-scene areas, where the dividing parameter may be a dividing value, that is, the number of partitions for dividing the scene area of the virtual scene.

Optionally, the volume of the bounding box of the scene area of the virtual scene is divided by the volume of the bounding box of the virtual character and rounded to obtain a division parameter, and the scene area is divided (Split) by using the division parameter to obtain a plurality of sub-scene areas, where the division parameter may be a detail value of each axial direction of the bounding box of the scene area of the virtual scene.

As an optional implementation, the method may further include determining a partitioning parameter based on the outline information of the virtual character, including: determining a first bounding box of the virtual character; a side length of the sub-scene region is determined based on the side length of the first bounding box.

In this embodiment, in order to avoid a situation that the boundary of the sub-scene region passes through the body of the virtual character, the volume of each sub-scene region obtained by dividing the scene region needs to be larger than the volume of the virtual character, that is, the boundary of the sub-scene region cannot pass through the body of the virtual character, so that the first bounding box of the virtual character may be determined first, then the side length of the first bounding box is adjusted, and the adjusted side length is determined as the side length of the sub-scene region, that is, the side length of the bounding box of the sub-scene region, where the first bounding box is used to represent the contour information of the region occupied by the virtual character in the virtual scene.

As an optional implementation, the method may further include determining a side length of the sub-scene region based on the side length of the first bounding box, including: and determining the side length of the first bounding box as the side length of the sub-scene area according to the result of adjusting the side length of the first bounding box by the target coefficient.

In this embodiment, in order to make the side length of the sub-scene region greater than the motion amplitude of the virtual character in the virtual scene, the side length of the first bounding box may be adjusted by using a target coefficient, and the adjusted side length is determined as the side length of the sub-scene region, where the target coefficient may be determined by the motion amplitude of the virtual character, the target coefficient may be an amplification factor of the side length of the first bounding box, for example, the value of the target coefficient is root 2, and then the length of the side length of the first bounding box is determined as the side length of the sub-scene region, which is only illustrated here by way of example and is not limited specifically.

As an optional implementation manner, the method may further include determining a partitioning parameter based on the outline information of the virtual character, including: determining a first enclosure box of the virtual role and a second enclosure box of the scene area; a partitioning parameter is determined based on the first bounding box and the second bounding box.

In this embodiment, a value obtained by dividing a volume of a second bounding box of the scene area by a volume of a first bounding box of the virtual character and then taking an integer may be determined as the partition parameter, where the second bounding box is used to represent the contour information of the scene area, and the first bounding box is used to represent the contour information of the area occupied by the virtual character in the virtual scene.

As an optional implementation manner, in step S204, the dividing the scene area according to the dividing parameter to obtain a plurality of sub-scene areas includes: determining at least one of the following sub-scene regions according to the partitioning parameter: region location, location of the corresponding depth camera, and region identification.

In this embodiment, after determining the dividing parameters based on the contour information of the virtual character, the scene regions are divided according to the dividing parameters, and a region position of each sub-scene region, a position of the depth camera corresponding to each sub-scene region, and a region identifier of each sub-scene region are obtained, where the region position may be a position where each sub-scene region is located in a scene region of the virtual scene, and the region position may be represented by using three-dimensional coordinates, for example, (1, 2), and the depth camera may be used to capture a depth map of the sub-scene region, and the region identifier may be an Id of the sub-scene region.

Alternatively, the area Location of each sub scene area is uniquely identified by Id, for example, the minimum coordinate (Min Location) and the maximum coordinate (MaxLocation) of the bounding box of the scene area are gradually increased from Min Location to Max Location, id is sequentially increased by 1 in the increasing order of coordinate axes (ZYX) from one axis to the next axis, so as to obtain the area Location and Id of each sub scene area, for example, one scene area is divided into 8 sub scene areas, and Id and the area Location of the scene area may be expressed as: 1: (0, 0), 2: (0, 1), 3: (0, 1, 0), 4: (0, 1), 5: (1, 0), 6 (1, 0, 1), 7: (1, 0), 8: (1, 1), which is herein described by way of example only and not by way of limitation.

As an alternative implementation, in step S206, baking the first virtual object included in the sub-scene region to obtain a first depth map includes: determining a shooting area of the depth camera for the virtual scene based on the sub-scene area; a first depth map captured by a depth camera over a capture area is acquired.

In this embodiment, a shooting area of the virtual scene by the depth camera is determined according to the volume of the sub-scene area, and a first depth map corresponding to the sub-scene area is shot by the depth camera, where the first depth map may be used to characterize the distance between the virtual character in the sub-scene area and the depth camera.

Alternatively, the sub-scene regions may be located within the shooting region such that transitions between different sub-scene regions intersect, that is, the depth map of each sub-scene region may partially overlap, such that the sub-scene region division boundary is not exceeded even if the virtual character is in motion, such as running and jumping.

Alternatively, the shooting area of the depth camera for the virtual scene may be larger than the volume of the bounding box of the virtual character in the sub-scene area, for example, the size of the volume of the bounding box of the sub-scene area, root 2, may be taken as the shooting area of the depth camera, and is not limited herein.

As an optional implementation manner, the method may further include that the first depth maps respectively corresponding to two adjacent sub-scene regions include depth maps of the same part of the first virtual object.

In this embodiment, since the sub-scene regions are located in the shooting region of the depth camera, the first depth maps acquired by the depth camera in two adjacent sub-scene regions include the same depth map partial depth map of the first virtual object, so that when a virtual character enters different sub-scene regions, the first depth maps of the sub-scene regions can be seamlessly switched and loaded.

As an optional embodiment, the method may further include, in response to the second virtual object moving to the sub-scene area, acquiring a second depth map of both the first virtual object and the second virtual object captured by the depth camera on the capture area; and creating the second depth map as a second shadow map, and rendering and displaying a second target shadow representation on the virtual character based on the second shadow map.

In this embodiment, if a dynamic object appears in the sub-scene area, that is, when the second virtual object moves to the sub-scene area where the first virtual object is located, the first virtual object and the second virtual object need to form a shadow together for the virtual character, a second depth map of the first virtual object and the second virtual object captured by the depth camera on the capturing area may be dynamically obtained through Id of the sub-scene area, and the second depth map may be created as a second shadow map, and a second target shadow representation is rendered and displayed on the virtual character based on the second shadow map, where the second depth map may be used to represent a distance between the first virtual object and the depth camera captured by the depth camera on the capturing area and a distance between the second virtual object and the depth camera, the first virtual object may be an object in a stationary state in the sub-scene area, and the second virtual object may be an object in a moving state in the sub-scene area, for example, a moving box.

Optionally, the second depth maps of the first virtual object and the second virtual object may be obtained by directly overlaying the depth map corresponding to the first virtual object and the depth map corresponding to the second virtual object, or may be obtained by first creating the depth map corresponding to the first virtual object as a shadow map of the first virtual object, creating the depth map corresponding to the second virtual object as a shadow map of the second virtual object, and then overlaying the shadow map of the first virtual object and the shadow map of the second virtual object, which is not specifically limited herein.

As an optional embodiment, the method may further include determining, as the first virtual object, a virtual object called from a database based on a region identifier of the sub-scene region, where a correspondence between the region identifier and the virtual object included in the sub-scene region is stored in the database.

In this embodiment, the corresponding relationship between the area identifier of the sub-scene area and the virtual object included in the sub-scene area may be stored as list data by means of a key-value pair, for example, (the area identifier of the sub-scene area, the virtual object list), and the list data is stored in the database, when a dynamic object appears in the sub-scene area, the first virtual object may be directly called from the list data in the database by the area identifier of the sub-scene area, and then the depth camera may capture only the depth map of the first virtual object, and this step may also be performed in an offline state as in the static baked shadow mapping technique, without performing additional performance consumption.

The technical solutions of the embodiments of the present application are further described below by way of example with reference to preferred embodiments.

In the virtual scene development process, the picture reality can be enhanced through the shadow, but the shadow is realized, so that the game performance is consumed greatly and is difficult to process, and the shadow effect with attractive performance and low performance consumption is a difficult problem of optimization processing in the industry, for example, the shadow without edge saw teeth and moire fringes is realized, or the shadow precision is improved.

In the virtual scene, the shadow effect can be divided into two types according to a defined criterion of a sender and a receiver, that is, the shadow effect caused by the object to other objects and the shadow effect caused by other objects to the object, in this embodiment of the present application, a performance optimization method mainly analyzes the shadow effect caused by other objects (e.g., scene objects) to the object (e.g., virtual characters).

Cartoon rendering is a more popular rendering style, and usually the cartoon rendering has some non-physical and real representations, for example, the avatar can accept the shadow caused by the scene object to the avatar, but at the same time, the scene object itself has no shadow, and the avatar has no shadow to the scene object, fig. 3 (a) is a schematic diagram of implementing a shadow effect according to the embodiment of the present application, as shown in fig. 3 (a), only the window 32 and the wall 33 of the avatar 31 cause the shadow to the avatar, as shown by the black oval area in the diagram, and the avatar does not cause the shadow to the ground 34, fig. 3 (b) is a schematic diagram of implementing another shadow effect according to the embodiment of the present application, as shown in fig. 3 (b), the black oval area on the avatar 31 represents the shadow caused by the window 32 to the avatar 31 itself.

In a related art, the light source is set to be dynamically movable by a CastShadow switch of the UE4 engine, which sets scene objects, so that all objects can cast shadows between each other, but this method can cause the objects (windows, boxes, people) in the scene to be shadowed between each other, and the generation of the depth map of the whole area in real time is very resource-consuming and may cause a problem of accuracy loss.

In another related art, the Shadow effect is achieved by statically baking a depth map of a scene by using a Shadow Mask technology, converting a depth map matrix into a Shadow map, and then using the Shadow map on a virtual character, for example, using the Shadow Mask technology, a scene (window) is deeply photographed on an RT by using a SceneCapture2D camera, and then the RT texture is directly loaded on a character Shader during a game running to perform the Shadow effect, but if a scene area is large (for example, 1 km × 1 km), the baked depth map is required to retain enough precision, and an RT texture is very large, so that the RT texture needs to be matched with a Shadow (cascodewmap) to load Shadow maps of different levels far and near, which not only increases the amount of the multistage cascade Shadow maps stored in a memory, but also cannot ensure that the Shadow cast on the character of the scene is clearly represented correctly due to a precision loss, and in addition, the statically baked depth map is determined during an off-line baking, and a character cannot be updated during the running to correctly cast a movable object on the scene.

However, this embodiment of the present application provides a Shadow optimization method based on Shadow Mask, which can optimize the generation area of the Shadow while implementing the above Shadow effect to ensure the accuracy requirement of the depth map, and also can implement that the movable object in the virtual scene only causes the Shadow effect on the human object, but not the Shadow effect on the floor.

Further describing a Shadow Mask-based Shadow optimization method provided by this embodiment of the present application, the method may include the following two parts.

The first part, editing (Editor) is realized in an off-line state, and the logic of baking Shadow Map by regions is added on the basis of the Shadow Mask.

Fig. 4 is a schematic diagram of a regional baking operation interface according to an embodiment of the present application, as shown in fig. 4, each small Box represents a Cell, the virtual character is located in a region of the scene to be baked, a region Box may be first placed to cover the entire virtual scene of the depth map to be baked, and then a subdivision value of each axis of the number-of-divisions (Split) is defined, for example, 5 × 5.

Alternatively, the Split value for Split may be obtained by calculating the volume of the avatar, bounds, and then dividing it by the volume of the entire scene area, box, and rounding.

It should be noted that the divided region volume needs to be larger than the occupied volume of the virtual character in the virtual scene, that is, the boundary of the divided region cannot pass through the body of the virtual character, for example, the upper half body of the virtual character is in the region a, and the lower half body of the virtual character is in the region B, because the same virtual character Shader can only load one region depth, if the above situation occurs, the Shader loading region depth map of the virtual character will be in error.

Optionally, when the depth map is shot, the size of the volume of the minimum region × root 2 may be taken as the shot region, so that there is a partial overlap between each minimum region, and thus when the virtual character Shader enters a different minimum region, the depth map of the different minimum region may be loaded in a seamless switching manner, so that even if the virtual character is in a motion state, such as running and jumping, the situation that the boundary of the minimum region is exceeded does not occur, where the volume of the minimum region may be determined by obtaining a bounding box (bounding box) of the virtual character, and only a value greater than the whole virtual character is required, and no specific limitation is made herein.

Note that, the root 2 in the "volume of the minimum region × root 2" is merely an example, and is not particularly limited.

Next, defining a Box covering the whole scene area, dividing the Box into a plurality of partition areas, each area being a Cell, and then calculating the position and Id of each Cell and the position of the corresponding depth camera, including: calculating the location of each Cell, id, and the location of its corresponding depth camera may include: making a Shadow Map of each Cell, defining the length, width and height of each Cell, the position of the minimum world position point of a Box, the longest edge root number 2, an Id list of the cells, all static grid bodies in a storage scene, region division and three-dimensional variables, and corresponding the position of each Cell to a depth camera; constructing a function, calculating a numerical value under an editor, ensuring that the minimum XYZ value of the divided area is 1, resetting an Id list, calculating data of the Cell, defining a Box covering all scene areas through the minimum position and the maximum position of the XYZ of the Box, dividing the Box into a plurality of cells according to Split, traversing subscripts of the cells in the X direction, the Y direction and the Z direction, and storing the Id of each Cell in the data list; outputting the length, width, height, longest edge, root number 2 of the Cell and the position of the minimum world position point of the Box; and calling a function (such as a lamb function), storing all Static Mesh in the scene in an array, and storing objects which are not movable objects in the scene in the array to obtain a Static grid body on the Static grid body.

Alternatively, the Min Location and MaxLocation of the entire scene area Box may be gradually increased from Min Location to Max Location, and Id may be sequentially increased by 1 in the order of increasing axis-by-axis of the coordinate axis (ZYX) to obtain the Location and Id of each Cell, for example, if one scene area Box is divided into 8 cells, the Id and Location of each Cell may be: 1: (0, 0), 2: (0, 1), 3: (0, 1, 0), 4: (0, 1), 5: (1, 0), 6 (1, 0, 1), 7: (1, 0), 8: (1,1,1).

Finally, acquiring a static depth map corresponding to each partition area in the virtual scene based on the depth camera, and outputting a data list to obtain a plurality of static depth maps, namely a basis for making a shadow map, comprising: the timer calls a function to process each Cell; distributing storage space for distributed block Shadow Map, shadow texture storage list, matrix transformation of each Cell relative to a depth camera, ID number of the Capture, corresponding Cell number, sky parallel light source and light direction of directional light; performing overtime statistics, storing a depth map captured by the Capture, all static grids of a scene and a camera for shooting depth; determining that the save path cannot be null; acquiring a directional light source with a single scene, acquiring the direction of the directional light, and calling once every 0.01 second until all cells are processed; setting a depth camera to be allowed to shoot all objects in the current scene; dynamically creating an RT value containing a single channel and assigning values, placing the RT on a scene Capture component, setting the shooting width of a camera, acquiring the position of a light source, setting the depth camera to rotate relative to a bounding box, shifting the depth camera to 10000 units in the light source direction, updating the position of the depth camera, converting an inverse matrix of the depth camera into an array, creating the depth RT into a static texture, storing the static texture under a file, circularly processing the next Cell next time, and emptying a timer if an Index (Index) exceeds the maximum value of the Cell, so as to prove that all cells have finished Capture depth.

Fig. 5 is a schematic diagram of a depth map corresponding to each region in a virtual scene according to an embodiment of the present application, as shown in fig. 5, the depth map corresponding to a plurality of different sub-regions is included in the diagram, the number below each depth map represents Id of the depth map, and the shadow texture 109 and the shadow texture 110 are parts of the water tower-like object that overlap in the two regions, which is a problem of the minimum boundary transition of the sub-regions solved by the embodiment of the present application.

And the second part is realized in a running (running) state, and judges whether to switch the dynamic Capture partition regional depth map or not and optimizes the judgment process based on the obtained data list.

When a game runs, a dynamic object may appear in a virtual scene, and the movement of the dynamic object may affect the shadow effect of the scene projected onto the character Shader, so that when a moving object enters the divided area where the virtual character is located, the depth map of the cell can be re-captured dynamically instead of re-capturing the whole virtual scene area.

In order to achieve the above effect, optimization may be performed on the basis of the data list obtained in the first part, and the optimization includes: acquiring bounding boxes of all objects in the virtual scene by calling a UE4 function (for example, a GetBound function); traversing each Cell under the condition that the area cells are divided; and judging which object bounding boxes are contained in each Cell, adding the objects into a list corresponding to the Cell, storing the objects as list data in a key value pair mode (for example, TMap < Id of the Cell and an object list), and acquiring the object list according to the Id of the Cell when the depth of the Cell is dynamically updated, so that the depth camera only captures the depth of the objects and the movable objects (boxes).

Optionally, the obtained data is expansion data of the first partial data list, and therefore, the steps may also be performed in an offline state without performing performance consumption.

The beneficial effects brought by the technical scheme of the embodiment of the application can include: the problem of transition of the regional division boundary is solved; the preprocessed object list data is obtained, and objects can be captured as required when the depth map is dynamically acquired, so that partial performance optimization is realized; on the basis of the Shadow Mask technology, the optimized content of the region division algorithm is added, so that the effect that a depth map can be generated by 'static objects' and 'dynamic objects' in a scene in a minimum region mode, shadows are projected on virtual roles, and Shadow influence on other scene objects is avoided is achieved.

In the embodiment of the application, the optimization content of the region division algorithm is added on the basis of the Shadow Mask technology, so that a static depth map of each Cell in a region in a scene is obtained, and a data list is output; when the depth of the Cell is dynamically updated, the corresponding object list is obtained from the data list according to the Id of the Cell, and the depth camera is enabled to only capture the depth of the object and the moving object so as to achieve the purposes of optimizing the generation area of the shadow and ensuring the precision of the depth map, thereby solving the technical problem that the shadow effect which is in line with the requirement of the virtual scene cannot be realized, and achieving the technical effect of realizing the shadow effect which is in line with the requirement of the virtual scene.
