According to an aspect of an embodiment of the present invention, there is provided a collision volume mapping method, which may optionally, as an alternative implementation, be applied, but not limited, to the environment shown in FIG. 1.

The user device 104 may receive the mapping instruction, obtain a mapping identifier in the mapping instruction after receiving the mapping instruction, and add a target mapping corresponding to the mapping identifier to an bounding volume of a first collision volume, where the first collision volume is a target collision volume to which the color mapping has been added but to which the reflection mapping has not been added. After the target map is added, a reflection map is added to the first collision volume to which the target map is added, and the final result is obtained.

It should be noted that the user device 104 may be an unconnected device, i.e., not interacting with the server 112 via the network 110, and is also allowed.

Optionally, as an optional implementation, as shown in fig. 2, the method for mapping a collision volume includes:

s202, receiving a chartlet instruction for requesting to add a target chartlet to a target collision body in a virtual three-dimensional scene, wherein the target collision body is the collision body added with a color chartlet and a reflection chartlet, the color chartlet records the surface color of the target collision body, the reflection chartlet records the surface texture of the target collision body, and the chartlet instruction carries a chartlet mark of the target chartlet;

s204, acquiring a first collision body corresponding to the target collision body, wherein the first collision body is a collision body added with a color map but not added with a reflection map;

s206, determining a bounding volume of the first collision volume;

s208, adding the target map to the bounding volume to obtain a second collision volume;

s210, adding the reflection map to the second collision body to obtain the target collision body added with the target map.

Alternatively, the collision volume mapping method described above may be applied, but not limited to, in a gaming application in the field of gaming, which may include, but is not limited to, one of the following: three-dimensional (3D) game applications, Virtual Reality (VR) game applications, Augmented Reality (AR) game applications, Mixed Reality (MR) game applications. Alternatively, it may be applied in other 3D environments. Such as during development, testing, etc.

Taking the application to the game process as an example, for a 3D game, the game may include a racing car, when a user wishes to add a map, such as a pictogram, to the racing car, the game client may be controlled to send a map instruction, the game client receives the map instruction, obtains a racing car to which a color map is added and to which a reflection map is not added, adds the pictogram to an enclosure of the racing car to obtain an added racing car, and adds the reflection map to the added racing car to obtain a final racing car. The last racing car can see that the heart-shaped picture is attached to the racing car, and the heart-shaped picture is seen from various visual angles, so that the heart-shaped picture is reduced in shape.

Through the embodiment, the method can improve the display effect of the added target map when the target map is added to the target collision body in the virtual three-dimensional scene.

The target map in the scheme can be a map with any content, and the target collision body can be a collision body added with a color map and a reflection map (in a general virtual three-dimensional space, after the color map is added to the collision body, a user can see the external color of the collision body during display, and after the reflection map is added, the user can see the reflection gloss during display). A first collision volume can be obtained by adding a color map to one collision volume, and a target collision volume can be obtained by adding a reflection map to the first collision volume.

Optionally, the enclosure mentioned in the present embodiment is a closed space completely enclosing the collision body.

In this scheme, when adding the target map to the bounding volume of the first collision volume, the target position on the bounding volume needs to be determined. The map instruction carries a target position, after the map instruction is obtained, the target position can be obtained from the map instruction, the target map is added to the target position, and the central point of the target map is kept aligned with the target position.

Optionally, in the process of determining the target position, a trigger operation may be received through a display screen of the terminal, where the trigger operation may be a touch operation performed on the touch screen, including a click operation, a long-time press operation, and the like, and the trigger operation may also be obtained by inputting a trigger position through an input device, for example, a mouse click operation, a long-time press operation, and the like. The trigger operation is an operation performed by one point on the display screen. The point is a first operation position corresponding to the trigger operation. For example, the user touches a point on the touch screen, and the point is taken as the first operation position.

After the first operation position is acquired, a second operation position corresponding to the first operation position on the enclosure body is determined. The second operation position may be an intersection position of the object ray projected from the first operation position and the bounding volume, the object ray being a ray projected toward the bounding volume along a current viewing angle for displaying the virtual three-dimensional scene.

After the second operation position is determined by the method, the second operation position is the target position. And after the target position is determined, pasting the target map on the target position.

Optionally, in the scheme, when the target map is pasted, the target map may be pasted to the enclosure at a certain angle.

Alternatively, after the target position is determined, a third operation position corresponding to the target position may be determined on the first collision volume. The third operating position is a position on the first collision body.

In the virtual three-dimensional scene, creating any three-dimensional collision volume requires determining a normal for each point on the collision volume. The normal is the normal to the plane of each point in the process of creating the three-dimensional collision volume. Therefore, after the third operation position is determined, the normal vector corresponding to the third operation position can be determined. When adding the target map to the first collision volume, the target map is pasted onto the target locations of the bounding volume along the negative direction of the finding vector.

Optionally, in this scheme, after the target map is attached to the first collision body, the position of the target map on the first collision body may be adjusted at any time. For example, after the user wants to paste the first collision body on the target map, the user may trigger an operation to a point on the display screen again to obtain an adjustment instruction, where the adjustment instruction carries a fourth operation position triggered by the user on the display screen. The fourth operating position has a corresponding fifth operating position on the enclosure, and the method of determining the fifth operating position is the same as the method of determining the second operating position. The fifth operation position is the intersection position of the target ray projected from the fourth operation position and the bounding volume, and the target ray is the ray projected to the bounding volume along the current visual angle for displaying the virtual three-dimensional scene. After the fifth operation position is determined, the target map that has been attached to the first collision body may be adjusted to the fifth operation position, thereby achieving adjustment of the target map position. After adding the target map to the first collision volume to obtain a second collision volume, a reflection map may be added to the second collision volume to obtain a target collision volume to which the target map is added. Compared with the method of directly pasting the target map on the target collision body, the method and the device realize the reduction of the deformation of the target map and improve the effect of the pasted target map.

Optionally, in the present solution, a target map or a target collision volume added with the target map may also be added to the block chain.

The blockchain in the scheme is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism and an encryption algorithm. A block chain (Blockchain), which is essentially a decentralized database, is a series of data blocks associated by using a cryptographic method, and each data block contains information of a batch of network transactions, so as to verify the validity (anti-counterfeiting) of the information and generate a next block. The blockchain may include a blockchain underlying platform, a platform product services layer, and an application services layer.

The block chain underlying platform can comprise processing modules such as user management, basic service, intelligent contract and operation monitoring. The user management module is responsible for identity information management of all blockchain participants, and comprises public and private key generation maintenance (account management), key management, user real identity and blockchain address corresponding relation maintenance (authority management) and the like, and under the authorization condition, the user management module supervises and audits the transaction condition of certain real identities and provides rule configuration (wind control audit) of risk control; the basic service module is deployed on all block chain node equipment and used for verifying the validity of the service request, recording the service request to storage after consensus on the valid request is completed, for a new service request, the basic service firstly performs interface adaptation analysis and authentication processing (interface adaptation), then encrypts service information (consensus management) through a consensus algorithm, transmits the service information to a shared account (network communication) completely and consistently after encryption, and performs recording and storage; the intelligent contract module is responsible for registering and issuing contracts, triggering the contracts and executing the contracts, developers can define contract logics through a certain programming language, issue the contract logics to a block chain (contract registration), call keys or other event triggering and executing according to the logics of contract clauses, complete the contract logics and simultaneously provide the function of upgrading and canceling the contracts; the operation monitoring module is mainly responsible for deployment, configuration modification, contract setting, cloud adaptation in the product release process and visual output of real-time states in product operation, such as: alarm, monitoring network conditions, monitoring node equipment health status, and the like.

The platform product service layer provides basic capability and an implementation framework of typical application, and developers can complete block chain implementation of business logic based on the basic capability and the characteristics of the superposed business. The application service layer provides the application service based on the block chain scheme for the business participants to use.

For example, the scheme may be applied to a client running a game, and the client may be a mobile phone. The display screen of the mobile phone displays a target collision body in a virtual three-dimensional scene, such as a virtual racing car, and the virtual racing car is used for being controlled by a user to play in a game. Fig. 3 may be a view of a virtual race car in a virtual three-dimensional scene displayed on a display screen, the virtual race car having added color and reflection maps and the virtual race car having not added a target map. At this time, if the target map needs to be added to the virtual racing car, the position of the target map to be attached can be determined first. For example, as shown in fig. 4, in the process of displaying the virtual racing car on the display interface shown in fig. 4, a first operation position on the display screen may be determined by clicking or long-pressing a certain position on the display screen, where the first operation position is required in an area where the virtual racing car is displayed on the display screen. For example, the user selects the position 402 as the first operation position (if the user is on a computer such as a PC, the first operation position may be selected by input hardware such as a mouse). After the first operating position is determined, a second operating position on the enclosure of the virtual race car may be determined. For example, as shown in FIG. 5, the user 502 in FIG. 5 may select a first operating position 506 on the display 504, cast rays 512 from the first operating position 506 along a current perspective (which may be the current direction of the camera 508) toward the virtual race car 510, thereby identifying a second operating position on the enclosure of the virtual race car 510 (the enclosure is not shown in FIG. 5), and identifying the second operating position as a target position to which the target map is to be attached. After the target location is determined, a target map may be attached to the target location. The bounding volume may be implemented by a MeshCollider component. By checking the Convex option on the assembly, a layer of enclosure can be set for the virtual racing car. For example, as shown in FIG. 6, FIG. 6 is a schematic view of an enclosure added for a virtual race car. After the target position is determined, in the process of pasting the target map, the pasting angle needs to be determined. If the target position on the bounding volume is determined, the third operating position on the first virtual car corresponding to the target position is determined (the virtual car is a car having a color map and a reflection map added to a collision volume, and the first virtual car is a car having a color map added to a collision volume and no reflection map added thereto). The third operating position is a position corresponding to the second operating position on the enclosure, and the position on the first virtual racing car which is the shortest distance from the second operating position may be determined as the third operating position. The third operation position corresponds to a normal vector, for example, as shown in fig. 7, the target map 704 is added to the bounding volume of the first virtual car along the negative direction of the normal vector 702 to obtain a second virtual car (the second virtual car is the first virtual car to which the target map is added), and then the reflection map is added to the second virtual car to obtain the virtual car to which the target map is added. After adding the target map, the user can also change the position of the target map. For example, as shown in FIG. 8, location 802 in FIG. 8 is the location where the target map was initially added. The user may click on a location on the display screen to determine the fourth operating position 804 and then add the target map to a fifth operating position on the bounding volume of the virtual race car corresponding to the fourth operating position 804. The target map for location 802 is deleted automatically or manually. Multiple controls may be displayed on the display screen so that different functions may be performed on the target map. E.g., rotate, delete, add, adjust, etc. The

positions

802 and 804 in fig. 8 are only exemplary, and in practical applications, the client generally displays them.

It should be noted that, if there are multiple target maps in the present solution, the target maps may be merged into one map for rendering, so that multiple target maps may be rendered by one rendering.

The collision volume in this scheme may be the model itself of the virtual car, the color map of the virtual car may be set to d, d may be added to the first set of uv (uv1), uv being the outer surface layer of the model in three-dimensional space. The first virtual car of the virtual cars may be c, then:

C＝tex2D(d,uv1) (1)

resulting in a first virtual car with the color map added. After the first virtual car race is obtained, a MeshCollider component can be added to the first virtual car race, and a Convex option in the MeshCollider component can be used for adding a bounding volume for the first virtual car race. The enclosure encloses the first virtual race car. Determining a first operation position in a display area through a trigger operation executed on a target collision body in the display area, then acquiring a second operation position on a bounding volume, wherein the second operation position can be h, acquiring a normal vector n of a point h, and adding a target map to the point h by taking the negative direction-n of the n as a target direction. And if a plurality of target maps exist, rendering the target maps to one map to obtain a map m, and adding the map m to the first virtual racing car to obtain a result g.

g.rgb＝c.rgb*(1.0-m*a)+m.rgb*m*a (2)

Wherein c is the first virtual racing car, m is the map where one or more target maps are located, and a is r in rgb.

After the operation, the second virtual racing car added with the color map and the target map is obtained. And adding a reflection map to the second virtual racing car.

The reflection map may be added to map 2, adding map 2 to the second virtual race car.

I＝reflect(-v,n) (3)

F＝texCUBE(_Cube,I)*fr (4)

Wherein, I is a reflection vector, n is a normal vector of the virtual racing car, v is a current view angle vector, i.e. a sight line vector, the value of the map 2 is _ Cube, and the reflection fresnel value is fr.

And adding the reflection map f to the second virtual racing car g to obtain a final result p, wherein p is the virtual racing car added with the target map.
