For purposes of making the objects, technical solutions, and advantages of the present disclosure more apparent, the principle and spirit of the present disclosure will be described below with reference to several exemplary embodiments. It should be understood that these embodiments are presented merely to enable one skilled in the art to better understand and practice the present disclosure and are not intended to limit the scope of the present disclosure in any way. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

In this document, it should be understood that any number of elements in the drawings is for illustration and not limitation, and that any naming is used only for distinction and not for any limitation.

The principles and spirit of the present disclosure are explained in detail below with reference to several representative embodiments thereof.

As described in the background art, the body structure of the model is usually constructed and completed in the modeling link, and after the modeling is completed, if a new structure is required to be added or a missing structure is required to be complemented on the model which has been completed in the modeling, the model needs to be returned to the modeling link to be modeled again.

However, referring to fig. 1, after the modeling is completed, links such as binding, lamplight materials, animation or rendering are usually performed, and if the modeling is returned to the modeling link for re-modeling, the links such as binding, lamplight materials, animation or rendering need to be performed again after the iteration of the previous link in sequence, which is high in cost and long in time consumption.

Further, in the related art, if a new structure is added to the model already modeled or a missing structure is added, for example, a muscle structure is added (an effect of changing from a muscle-free structure to a muscle-free structure), it is generally performed in a manner of re-modeling, adding a bone skin, or making a blend shape.

Specifically, in the scheme of implementing the additional model based on the re-modeling manner:

the scheme needs to reestablish a new model according to the appearance and structure of the original model so as to fill the missing structure or detail. The re-modeling scheme is typically used to repair or refine the structure and details of existing models.

However, the re-modeling approach has the following drawbacks:

the time cost is high: the re-modeling requires re-modeling, requiring a lot of time and effort. The precision is not high: the re-modeling may result in loss of detail or shape changes that affect the accuracy of the model. It is not practical: if multiple models need to be modified, the re-modeling approach is not practical.

Specifically, in the solution of implementing the additional model based on the way of adding the bone skin:

the method for binding the skeletal system and the surface of the model can simulate and manufacture the surface structure of the model in the appearance of the model, and the model needs to be bound by the skeleton first and then covered by the skin. The bone binding requires correspondence of the bone system to the model surface, thereby enabling control of the model. The skin needs to apply the actions of the skeleton system to the surface of the model, and then the skeleton is adjusted to a better state according to the structural requirement of the model, so that the structural effect of the model is simulated.

However, the manner of adding bone skin has the following disadvantages:

the limit is larger: the addition of bone skin requires a prior planning of the bone structure, which places constraints on the morphology and position of the muscles. Complicated manufacturing processes are required: adding bone skin requires complex manufacturing processes such as bone binding, weight adjustment, animation testing, and the like, requiring a great deal of skill and time. Unnatural: if the bone is improperly bound, or the weight adjustment is inaccurate, unnatural structures may be caused to affect the sense of realism of the muscle. Wiring problems lead to poor structural results: the problem that the model wiring cannot be optimized exists due to the fact that the weight is edited based on the original model, the wiring is overlarge or a pulling effect can be generated at the structure, and the model outline cannot be manufactured well.

Specifically, in the scheme of implementing the additional model based on the method of making a blend shape (blend deformer):

methods of fusing models of different states are commonly used for animation. The method needs to subdivide the model, then make models in different states, and finally fuse the models. The fused model can realize different forms and animation effects according to different control parameters.

However, the method of producing the blend shape has the following drawbacks:

deformation may be unnatural: since the model needs to be deformed when the blend shape is manufactured, if the deformation is unreasonable or unnatural, the sense of reality of the muscle can be affected. A significant amount of manufacturing time is required: requiring a significant amount of time and effort to make each key frame.

In addition, the way of re-modeling, adding a bone skin or making a blend shape cannot realize free migration of the additional model on the surface of the original model, otherwise, unnatural effects such as pulling can occur.

In order to solve the above problems, the present solution provides an additional solution for a model, specifically including: acquiring an original model and an additional model; fusing the additional model to the original model; and when the additional model moves on the original model, obtaining rotation information of the additional model based on normal line information of the vertex of the original model. In the method, when the additional model moves on the original model, the rotation information of the additional model can be dynamically adjusted according to the normal line information of the vertex of the original model, so that the illumination effect and the shadow effect of the additional model can be consistent with those of the original model.

Specifically, by identifying the binding mode of the superposition effect of the normal vector on the surface of the irregular model, the additional model can be attached to the surface of the original model to control free displacement, expansion and the like, and corresponding turning transition is made along with the radian turning of the original model, and the contact part of the additional model and the original model can be naturally fused into the original model. The model iteration requirement generated by insufficient effect in the three-dimensional animation production flow of the related technology is avoided, and the iteration work and time cost of reverse improvement are reduced.

Having described the basic principles of the present disclosure, various non-limiting embodiments of the present disclosure are specifically described below.

Reference is made to fig. 2, which is a schematic illustration of an application scenario of an additional method of modeling provided in an exemplary embodiment of the present disclosure.

The application scenario includes a local terminal device 210 and a server 220. The local terminal device 210 and the server 220 may be connected through a wired or wireless communication network. The local terminal device 210 includes, but is not limited to, a desktop computer, a mobile phone, a mobile computer, a tablet computer, a media player, a smart wearable device, a personal digital assistant (personal digital assistant, PDA) or other electronic device capable of performing the functions described above, and the like. The server 220 may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDNs (Content Delivery Network, content delivery networks), basic cloud computing services such as big data and artificial intelligent platforms, and the like.

In a specific implementation, the server 220 is configured to provide an additional service of a model to a user of the local terminal device 210, where a client in communication with the server 220 is installed in the local terminal device 210, through which the user can input an original model and an additional model, and after clicking an additional button, the client sends the original model and the additional model to the server 220, and the server 220 receives the original model and the additional model sent by the client; fusing the additional model to the original model; the user may also input a movement instruction for the additional model through the client, and the server 220 obtains rotation information of the additional model based on normal line information of vertices of the original model and gives the rotation information to the additional model when the additional model moves on the original model. Server 220 may also send dynamic or static images of the additional model moving on the original model to the client, which presents the image of the additional model moving on the original model to the user.

In some exemplary embodiments, additional methods of the model may be run on the local terminal device 210 or the server 220. When additional methods of the model are run on the server 220, the methods may be implemented and executed based on the cloud interaction system.

The cloud interaction system comprises a client device and a cloud game server.

In some example embodiments, various cloud applications may be run under the cloud interaction system, such as: and (5) cloud game. Taking cloud game as an example, cloud game refers to a game mode based on cloud computing. In the running mode of the cloud game, the running main body of the game program and the game picture presentation main body are separated, the storage and running of the control method of the moving state in the game are completed on the cloud game server, and the client device is used for receiving and sending data and presenting the game picture, for example, the client device can be a display device with a data transmission function close to a user side, such as a mobile terminal, a television, a computer, a palm computer and the like; but the cloud game server which performs information processing is a cloud. When playing the game, the player operates the client device to send an operation instruction to the cloud game server, the cloud game server runs the game according to the operation instruction, codes and compresses data such as game pictures and the like, returns the data to the client device through a network, and finally decodes the data through the client device and outputs the game pictures.

In the above embodiments, the description has been given taking an example in which the additional method of the model is run on the server 220, but the present disclosure is not limited thereto, and in some exemplary embodiments, the additional method of the model may also be run on the local terminal device 210.

In some exemplary embodiments, taking a game as an example, the local terminal device 210 stores a game program and is used to present a game screen. The local terminal device 210 is used to interact with the player through a graphical user interface, i.e. to download and install a game program and run it conventionally through an electronic device. The manner in which the local terminal device 210 provides the graphical user interface to the player may include a variety of ways, for example, it may be rendered for display on a display screen of the terminal, or it may be provided to the player by holographic projection. For example, the local terminal device 210 may include a display screen for presenting a graphical user interface including game visuals, and a processor for running the game, generating the graphical user interface, and controlling the display of the graphical user interface on the display screen.

In particular implementations, the local terminal device 210 may include a display screen and a processor. The local terminal device 210 is provided with a client, through which a user can input an original model and an additional model, and after clicking an additional button, the client transmits the original model and the additional model to the processor, and the processor receives the original model and the additional model transmitted by the client; fusing the additional model to the original model; the user can also input a moving instruction for the additional model through the client, and when the additional model moves on the original model, the processor obtains rotation information of the additional model based on normal line information of the vertex of the original model, and gives the rotation information to the additional model. The processor may also send a dynamic or static image of the movement of the additional model over the original model to the client, which presents the image of the movement of the additional model over the original model to the user via the display screen.

In some exemplary embodiments, the disclosed embodiments provide an additional method of providing a graphical user interface through a terminal device, where the terminal device may be the aforementioned local terminal device 210 or may be a client device in the aforementioned cloud interaction system.

Additional methods of modeling according to exemplary embodiments of the present disclosure are described below in connection with the application scenario of fig. 2. It should be noted that the above application scenario is only shown for the convenience of understanding the spirit and principles of the present disclosure, and the embodiments of the present disclosure are not limited in any way in this respect. Rather, embodiments of the present disclosure may be applied to any scenario where applicable.

Reference is made to fig. 3, which is a flow diagram of an additional method of modeling provided by an exemplary embodiment of the present disclosure.

An additional method of modeling, comprising the steps of:

step S310, an original model and an additional model are acquired.

In this embodiment, the addition of the models refers to the addition of one model to another model, the model added to the other model is referred to as an additional model for convenience of description, the model to which the other model is added is referred to as an original model, that is, the addition of the model refers to the addition of the additional model to the original model.

In particular, with reference to fig. 4, a spherical model 420 is attached to an arm of a character model 410 as an example.

In this embodiment, character model 410 is the original model; spherical model 420 is an additional model.

It should be noted that, the additional model is illustrated as the spherical model 420 for convenience of description and illustration, and the shape structure of the additional model is not limited to the spherical model or the model with a simpler shape structure, such as a cube model or a cuboid model, and the additional model may be a model with a more complex shape structure, such as a muscle model, a clothing model or an equipment model, etc. in the specific implementation.

The foregoing embodiment describes the definition of the original model and the additional model, and is illustrated in conjunction with fig. 4, and a specific manner of acquiring the original model and the additional model will be described below. Hereinafter, the present disclosure will be described by taking application to a modeling scenario and a game running scenario as an example.

In practice, in modeling scenarios, both the original model and the additional model may be input by a user, such as a modeler, animator, or special effects.

In some exemplary embodiments, the present disclosure provides functionality for inputting models, for example, a client may be provided for a user to input a model, through which the user can input any model and designate it as an original model or an additional model.

For example, a user enters a character arm model and a muscle model by designating the client, designates the character arm model as the original model, and designates the muscle model as the additional model.

In some exemplary embodiments, the present disclosure also provides a function of selecting a model, and may provide a client through which a user can select an arbitrary model from a model library and designate it as an original model or an additional model, for the user to select the model from the model library.

In particular, in a game running scenario, both the original model and the additional model may be determined and captured from the game scenario.

In some exemplary embodiments, there are several models in the game scene, and a client for a user to select a model from the virtual scene may be provided, and in response to a selection operation of the user on any model in any virtual scene, one of the selected models is taken as an original model, and the other model is taken as an additional model.

For example, a user selects a character arm model and a muscle model from a specified model library by a specified client, designates the character arm model as an original model, and designates the muscle model as an additional model.

Step S320, fusing the additional model to the original model.

In this embodiment, in order to achieve the effect of attaching the additional model to the original model, it is necessary to achieve the effect of fusing the additional model to the original model first, and hereinafter, a specific way of fusing the additional model and the original model will be described:

in some exemplary embodiments, the fusing the additional model to the original model includes:

moving the additional model onto the original model, wherein the additional model leaks at least partially out of the surface of the original model;

and performing fusion treatment on the intersection of the surface of the additional model and the surface of the original model.

In this embodiment, the control system of the additional model needs to be built before the additional model is controlled to move:

in some exemplary embodiments, after the additional model is acquired, the method further comprises:

associating the additional model with a preset bone;

Associating the preset skeleton with a preset controller;

in this embodiment, the preset skeleton is controlled by the preset controller to control the additional model by the preset skeleton.

Referring to fig. 5, in the present embodiment, a spherical model 420 (additional model) is associated with a preset bone 430; associating the preset skeleton 430 with a preset controller 440; the preset skeleton 430 is controlled by the preset controller 440 to control the spherical model 420 (additional model) by the preset skeleton 430.

In some exemplary embodiments, the method for controlling the additional model to move based on the constructed control system includes:

controlling the preset controller to move based on a movement instruction aiming at the additional model;

controlling the preset bone movement based on the movement of the preset controller;

controlling the additional model to move based on the movement of the preset skeleton;

in this embodiment, the movement of the preset controller, the preset bone movement and the additional model movement are synchronized.

In specific implementation, the preset controller is a tool for controlling the preset skeleton, and has no limitation on the form, and the form can be freely edited according to the requirement of a user and can be freely endowed with color or shape.

In practice, the model is usually bound to the skeleton, and the model is transformed by rotating and scaling along with the movement of the skeleton, so that the controller can achieve the purpose of animation by controlling the skeleton, namely, the controller controls the skeleton, and the model is bound to the skeleton and can follow the skeleton, so that the operation of the controller can be directly reflected on the model effect.

In this embodiment, in order to achieve the effect of convenient control, in some exemplary embodiments, the preset controller includes:

a controller of the geometry type.

In this embodiment, the preset controller of the geometry type may be rotated, translated, and/or scaled, etc., to change the pose and shape of the additional model. Because the geometric figure has the characteristic of being more regular, the processing process of mapping the operation of the controller aiming at the geometric figure type to the skeleton of the additional model is simpler, faster, higher in efficiency and lower in time delay.

In the above embodiments, the manner of controlling the movement of the additional model is described, however, the disclosure herein may control, in some possible embodiments, the adjustment of the shape and/or size of the additional model in addition to the movement of the additional model:

In some exemplary embodiments, in response to a shape adjustment instruction for the additional model, controlling adjustment of the shape of the preset controller based on the shape adjustment instruction;

and responding to a size adjustment instruction for the additional model, and controlling and adjusting the size of the preset controller based on the size adjustment instruction.

In the specific implementation, the shape and the size of the additional model may be adjusted separately or simultaneously.

In specific implementation, controlling and adjusting the shape of the preset controller may include replacing the current shape with other shapes, such as replacing a sphere shape with a cuboid shape; structural adjustments to the current shape, such as making the ellipsoid shape flatter and longer, may also be included, in which case the adjustments to the shape and size of the additional model are made simultaneously.

Wherein the adaptation of the shape and/or size of the additional model also facilitates the fusion and addition of the additional model and the original model.

In this embodiment, the additional model at least partially leaks out of the surface of the original model, which means that: the additional model may be in contact with the surface of the original model by means of a surface, or may be partly embedded in the original model.

As one example, fusion of the intersection of the surface of the additional model with the surface of the original model may be achieved using the shrnkwrap technique.

In this embodiment, a wrapped mesh object may be extracted and created from the mesh, NURBS, subdivision surface, and point cloud by the shrnkwrap technique. The ShrinkWrap cladding technology supports various geometric objects as input objects (e.g., point objects, NURBS objects, subdivision objects, grid objects, etc.), and thus has a wide range of applications, such as: a grid for 3D printing; an entity federation grid from a plurality of input objects; generating an entity grid from the 3D scan data segments; creating a grid without internal self-intersection; offsetting the grid to create a shell; reverse engineering workflow; generating a grid by using the point cloud object; an effective closed mesh, generated from broken or often difficult to repair geometry, etc.

As a specific example, referring to fig. 6, spherical model 420 (additional model) is moved onto character model 410 (original model), wherein spherical model 420 (additional model) partially leaks out of the surface of character model 410 (original model);

the intersection of the surface of spherical model 420 (the additional model) and the surface of character model 410 (the original model) is fused to form a fusion.

In this embodiment, in order to promote the fusion effect of the additional model and the original model, in some exemplary embodiments, after the fusion processing is performed on the intersection of the surface of the additional model and the surface of the original model, the method further includes:

the attenuation value at the intersection of the surface of the additional model and the surface of the original model is adjusted.

In this embodiment, when some points of the wrapper object strike the target object and other points do not strike, the attenuation values will deform smoothly across this boundary, with the larger the values, the smoother the boundary between the wrapper and the target.

In the above embodiment, the fusion effect of the additional model and the original model is improved by optimizing the fusion mode, however, in some exemplary embodiments, the fusion effect of the additional model and the original model may also be improved by improving the structure of the original model and/or the additional model, specifically:

in this embodiment, in order to promote the fusion effect of the additional model and the original model, after the original model is acquired, the original model may be subjected to subdivision processing.

In some exemplary embodiments, after obtaining the original model, the method further comprises:

And carrying out subdivision processing on the original model.

In some exemplary embodiments, the sub-dividing the original model includes:

acquiring wiring information of the original model;

and refining the wiring information to a preset multiple.

As an example, referring to fig. 7, description will be given of a case where a square model is taken as an original model, and wiring information of the square model is three-stage wiring of length, width and height.

After the cube is endowed with the skeleton skin information, the model binding precision is poor due to insufficient wire segments, and obvious edges and corners and pulling occur.

At this time, the model needs to be subdivided to improve the effect, and the Smooth wiring adding precision processing can be adopted, and when the dimensions are 1, the wiring can be added with one time of precision on the basis of the original wiring distribution, so that the two times of precision are overlapped.

In this embodiment, the original model is subdivided, so that the accuracy and detail of the original model can be improved, and the fusion effect of the additional model and the original model can be improved. The accuracy of subdivision may be adjusted as needed, and subdivision may be omitted if the wiring of the original model is sufficient.

In the above embodiments, the fusion effect of the additional model and the original model is improved by improving the structure of the original model, and in some exemplary embodiments, the fusion effect of the additional model and the original model may also be improved by improving the structure of the additional model, which is specific:

In this embodiment, in order to promote the fusion effect of the additional model and the original model, the following improvement may be made to the structure of the additional model:

in some exemplary embodiments, the surface of the additional model that is in contact with the surface of the original model has edges.

In the above embodiments, the additional model with the contact surface having edges may be more snugly incorporated into the original model.

Further, in some exemplary embodiments, a surface of the additional mold in contact with a surface of the original mold is a hollow structure.

In the above embodiment, the additional model with the hollow structure of the contact surface can be more fit into the original model.

Referring to fig. 8, in practice, a shows the additional model as a hollow structure, in which case b shows that when the additional model is fused to the original model, the edges of the additional model may act as fusion sites so that the additional model may be more snugly fused into the original model.

And step S330, when the additional model moves on the original model, obtaining rotation information of the additional model based on normal line information of the vertexes of the original model.

In practice, the additional model may be moved over the original model, and the control system of the additional model is the same as the control system of the additional model provided in the above embodiment.

In some exemplary embodiments, after the fusing the additional model to the original model, the method further comprises:

determining a nearest target vertex from the vertexes of the original model to the preset controller;

acquiring the position information of the target vertex;

and based on the position information, moving the additional model to a position characterized by the position information through the preset skeleton.

In some exemplary embodiments, the deriving rotation information of the additional model based on normal information of vertices of the original model includes:

acquiring normal line information of the target vertex;

and obtaining rotation information of the additional model based on the normal line information.

In some exemplary embodiments, the obtaining rotation information of the additional model based on the normal information includes:

And multiplying the normal information by a preset angle to obtain the rotation information.

In some exemplary embodiments, the preset angle includes:

ninety degrees.

In practice, the real rotation value can be obtained by multiplying 90 degrees by the normal information to obtain rotation information, considering that the axis quadrant is 90 degrees.

As a specific example, if the normal is recorded as 0.8 on the x-axis, characterizing that the normal is 0.8 units off the x-axis, it can be calculated that the difference from the x-axis rotation is 90-72=18 degrees.

Referring to fig. 9, in some exemplary embodiments, the determining a target vertex closest to the preset controller among vertices of the original model includes:

acquiring position information of the preset controller;

traversing the vertexes of the original model, and calculating the distances represented by the position information of each vertex and the position information of the preset controller;

and taking the vertex corresponding to the smallest distance in the distances as the target vertex.

In the above embodiment, according to the world coordinate position, each vertex of the original model is traversed, a vertex with the closest position between the preset controller and the original model is found, the coordinate value of the vertex is given to the additional model as its position value, and the normal direction value of the vertex is multiplied by 90 degrees to serve as the rotation value of the additional model, i.e. the additional model recognizes the turn along the normal direction of the original model and takes it as the rotation value of the self-walk.

Referring to fig. 10, the effect of modifying the normal orientation is to adjust the lighting and shading effects of the model surface so that the model appears more realistic and natural when rendered. The illumination reflection angle of the model surface can be changed by adjusting the normal direction, so that light rays can be reflected according to a more reasonable angle when striking the model surface, a more real illumination effect is generated, the normal mapping effect of the model surface can be changed by modifying the normal direction, the shadow effect of the model surface is affected, and the shadow is more real and natural.

In specific implementation, the lighting effect and the shadow effect, namely, the shadow effect, refer to the effect that the image or the video has a stereoscopic impression and a sense of reality by adjusting the contrast ratio of the lighting and the shadow. The shadow effect can be applied in many scenes, such as in a game, the realism and immersion of the game can be enhanced by adjusting the illumination and shadows.

Therefore, considering that the normal lines which are better in general are perpendicular to the model surface, it can be understood that ambient light can be perpendicular to each model surface, and therefore, the rotation value of the additional model on the original model surface can be calculated by using the condition.

Referring to fig. 11, in the present embodiment, a and B show the illumination effect and the shadow effect when the additional model is moved to different positions on the original model, respectively, it can be seen that the illumination effect and the shadow effect when the additional model is moved to different positions on the original model are different, and can be kept consistent with those of the original model at the positions where the additional model is located. It may be stated that, by the additional method of the model provided by the embodiment of the present disclosure, when the additional model moves on the original model, the lighting effect and the shadow effect of the additional model can be kept consistent with the original model.

From the foregoing, it can be seen that additional methods of modeling provided by embodiments of the present disclosure include: acquiring an original model and an additional model; fusing the additional model to the original model; and when the additional model moves on the original model, obtaining rotation information of the additional model based on normal line information of the vertex of the original model. In the method, when the additional model moves on the original model, the rotation information of the additional model can be dynamically adjusted according to the normal line information of the vertex of the original model, so that the illumination effect and the shadow effect of the additional model can be consistent with those of the original model.

Further, the beneficial effects that this disclosed technical scheme brought still include:

the additional model can be freely moved on the surface of the original model, so that the reality and naturalness of the model and the animation are improved;

the requirement of late binding and animation link matching iteration caused by the iteration of the model in the three-dimensional flow in the related technology can be avoided, the cost of the reverse improvement iteration work and time is reduced, the originality and the idea of the model optimization iteration can be directly realized in other links in the three-dimensional flow, the link limitation is avoided, and the creativity and the flexibility of the three-dimensional modeling are improved;

the free displacement and the expansion of the additional model can be realized, and the structure is automatically fused into the original model, so that the unnatural effects such as pulling and the like can not occur;

the problem of missing structure during model making is reduced, the quality and expressive force, the impression precision and the detail of the model are improved, and the overall model and the animation effect are more vivid;

the method can be applied to various models, including characters, animals, buildings, machinery and the like, and improves the transformation efficiency of the models in the whole three-dimensional flow;
