Description

Control method and device of snake-shaped virtual object, storage medium and electronic equipment

Technical Field

The present disclosure relates to the field of computer technologies, and in particular, to a method for controlling a serpentine virtual object, a control apparatus for a serpentine virtual object, a computer-readable storage medium, and an electronic device.

Background

At present, with the development of the internet, network games become another hot field at present, and meanwhile, higher requirements are also put forward for game animation production. Snakelike creatures are often encountered in game animation production, and the production difficulty of the snakelike creatures is often high in production difficulty, which is determined by the basic characteristics of the snakelike creatures. For example, the serpentine can perform an S-shaped motion, or the head can be held stationary while the body twists, or the serpentine has a soft body, etc.

In animation implementations, model resources are typically skinned by binding the model resources to the bones to drive the model into motion. However, generally, the body of the serpentine creature is bound on one skeleton, and the skeleton motion is controlled only by one displacement control point, so that the serpentine creature cannot perfectly move according to a preset route, and the local enlarging and reducing functions in animation production cannot be realized, and the muscle stretching effect cannot be achieved.

Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings.

In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the disclosure. One skilled in the relevant art will recognize, however, that the subject matter of the present disclosure can be practiced without one or more of the specific details, or with other methods, components, devices, steps, and the like. In other instances, well-known technical solutions have not been shown or described in detail to avoid obscuring aspects of the present disclosure.

Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale.

Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities.

Fig. 1 is a schematic diagram illustrating an effect of a control method of a snake-shaped virtual object in the related art, as shown in fig. 1, a skeleton of the snake-shaped virtual object is processed in two parts. Specifically, a bone chain is established from the neck to the tail and a bone is established from the head in a reverse direction by taking the neck as a demarcation point.

It can be seen that there is only one displacement control point, and all bones can move according to the displacement control point, so that the body cannot be freely controlled, and the free twisting of the body of the snakelike organism cannot be met.

And, because the limitation of one bone is large, the snake-shaped virtual object can not move according to the preset movement route.

In addition, during animation, a local enlarging or reducing expression effect is often used, and the enlarging and reducing functions cannot be realized in this way. Further, the skeleton chain is connected with one another, so that the snake-shaped virtual object cannot make stretching effect.

In view of the problems in the related art, the present disclosure provides a control method of a serpentine virtual object. Fig. 2 shows a flow chart of a control method of a serpentine virtual object, as shown in fig. 2, the control method of a serpentine virtual object comprises at least the following steps:

and S210, dividing the snake-shaped virtual object into a plurality of component parts according to the structure of the snake-shaped virtual object.

S220, aiming at a target part in the plurality of component parts, erecting more than two bones towards a target direction, wherein the target direction is determined according to the direction to be twisted of the target part.

And S230, erecting main controllers at key positions in the target part respectively, and establishing a binding relationship between each main controller and bones of more than two bones.

And S240, respectively controlling the motion of the bound bones according to the main controller.

In the exemplary embodiment of the present disclosure, on one hand, a plurality of bones are erected towards a target direction for a target part, so that the movement of the snake-shaped virtual object is flexibly controlled, and the requirement of flexible twisting of the snake-shaped virtual object is met; on the other hand, a main controller is erected at the key position of the target part, and the controller controls the rotation and displacement of the corresponding skeleton, so that the control difficulty of the snake-shaped virtual object is reduced, and the control effect of the snake-shaped virtual object is optimized.

The following describes each step of the control method of the serpentine virtual object in detail.

In step S210, the serpentine virtual object is divided into a plurality of component parts according to the structure of the serpentine virtual object.

In an exemplary embodiment of the present disclosure, the snake-shaped virtual object may be a snake or a dragon or other virtual objects, and this exemplary embodiment is not particularly limited to this.

The structure of the snake-shaped virtual object is divided, and the division can be carried out according to key points of the snake-shaped virtual object.

Wherein the key point may be determined according to a loop line of the serpentine-shaped virtual object. Specifically, the more the loop lines of the serpentine-shaped virtual object are, the more the detachable component parts are.

Therefore, after the serpentine virtual object is divided by the key points, a plurality of component parts can be obtained.

In step S220, two or more bones are erected in a target direction for a target portion among the plurality of component portions, the target direction being determined according to a direction in which the target portion is to be twisted.

In an exemplary embodiment of the present disclosure, the target site may be determined among a plurality of constituent sites of the serpentine virtual object.

In an alternative embodiment, the target site is a body site or tail site of a serpentine virtual object.

In addition, other constituent parts may be determined as the target part according to actual conditions, and this is not particularly limited in the present exemplary embodiment.

After the target site is identified, a plurality of bones may be erected in a target direction.

In an alternative embodiment, two or more bones are erected at a predetermined interval in a direction perpendicular to the central axis of the target site.

Since the model of the body or tail portion of the serpentine-shaped virtual object is a whole segment, it is possible to divide the whole segment of the model into N segments at a preset interval distance and keep the length of each segment uniform.

Also, the target direction may be determined by the direction to be twisted. Specifically, the target direction may be a direction perpendicular to the central axis of the target portion.

For example, when the central axis of the target portion is in the horizontal direction, the direction in which the bone is to be erected may be determined to be the vertical direction; when the central axis of the target site is in the vertical direction, the direction of the bone to be erected can be determined to be the horizontal direction. In addition to this, when the central axis of the target site is in other directions, the direction of the bone to be erected can also be determined in a perpendicular relationship.

After the direction in which the bones are to be erected is determined, the positions in which the bones are to be erected can be determined to erect more than two bones.

In an alternative embodiment, two or more bones start at a center point of the target site, the center point being a point on the central axis.

For example, the center point of the target portion may be determined according to the model highest point and the model lowest point of the target portion, i.e., the center point is the center of the model highest point and the model lowest point.

Therefore, two or more bones can be erected in a predetermined direction as a target portion with the center point as a starting point and the preset spacing distance as the spacing size. And more than two bones are erected, so that the movement of the target part can be flexibly controlled, and the free twisting of the snake-shaped virtual object is met.

In addition, when the head part is the target part, the corresponding skeleton can be erected with the neck as the axis. The direction of the frame may be a forward direction of the center axis of the target portion, or may be another direction, which is not particularly limited in the present exemplary embodiment.

Correspondingly, the skeleton of the tail portion may be erected in the same manner as the skeleton of the body portion, or may be erected around a tail key point of a skeleton chain, and the erection direction may be a backward direction of the central axis of the target portion, which is not particularly limited in this exemplary embodiment.

In step S230, main controllers are respectively erected at key positions in the target site, and a binding relationship between each main controller and a bone of the two or more bones is established.

In an exemplary embodiment of the present disclosure, the master controller may be established first, before the master controller is erected.

In an alternative embodiment, an overall controller is established for the serpentine virtual object, which is used to control all the master controllers. In an alternative embodiment, the overall controller is located at an origin position in the spatial coordinate system, and the overall controller is used for controlling the position of the serpentine virtual object in the spatial coordinate system.

It is worth noting that the overall controller has a marking function. That is, in the process of setting up the controller, the overall controller is regarded as the coordinate origin of the space coordinate, so that the position information of other structures exists in the world coordinate system.

After the master controller is preferentially established, the master controller can be further erected at the key position of the target part.

In an alternative embodiment, the key location is a joint location of the serpentine virtual object.

The joint part of the snake-shaped virtual object is the joint between the head part, the body part and the tail part of the snake-shaped virtual object.

The number of main controllers erected at key positions can be erected according to the length and effect of the snake-shaped virtual object.

Specifically, after the main controller is erected at a key position, the main controller can be continuously added according to an equal division principle.

For example, when the distance between two critical locations is 10 meters, a main controller can be installed at 5 meters. If a more flexible effect is actually desired, the erection can be continued under the condition that the two main controllers are 5 meters.

It is worth mentioning that the overall controller can control the rotation and displacement of the main controller, but the main controller cannot reversely control the overall controller.

After the main controller is erected, the secondary controller can be erected continuously.

In an alternative embodiment, one or more secondary controllers are generated for any primary controller, and a binding relationship is established between each secondary controller and a target bone determined from the bone with which the corresponding primary controller has a binding relationship, the primary controller being configured to control the corresponding one or more secondary controllers.

In an alternative embodiment, fig. 3 shows a flow diagram of a method of generating a secondary controller, as shown in fig. 3, the method comprising at least the steps of: in step S310, a target number of secondary controllers to be established is determined according to a distance between the target master controller and the adjacent master controller.

Since the secondary controllers are used to engage the transitions between the primary controllers, the target number may be determined by equally dividing the distance between the target primary controller and the adjacent primary controller. For example, when the distance between the target master controller and an adjacent master controller is 2 meters, the target number can be obtained by equally dividing 2 meters.

In step S320, a target number of secondary controllers is generated for the target primary controller.

After determining the target number, an equal number of secondary controllers may be generated evenly between the target primary controller and the neighboring primary controllers.

In the present exemplary embodiment, the target number of the secondary controllers may be determined according to the distance between the target primary controller and the adjacent primary controller, and the secondary controllers are erected to achieve accurate erection of the secondary controllers.

After the secondary controller is erected, the binding relationship between the secondary controller and the target skeleton can be correspondingly established.

Since the bone itself has the properties of rotation and displacement, but the properties of rotation and displacement of the bone are assigned to the master controller, the target bone is the bone having a binding relationship with the master controller. In addition, the primary controller may control one or more secondary controllers.

Further, in an alternative embodiment, the control strength of the master controller for each corresponding secondary controller is determined according to the distance between the master controller and each corresponding secondary controller.

Since the primary controller can control the secondary controllers, the constraints of the secondary controllers can be evenly distributed to the corresponding primary controllers.

For example, when one secondary controller is controlled by two primary controllers, either of the two primary controllers may control the 50% spin profile of the secondary controller.

Besides, the control intensity of the main controller to the secondary controller can be embodied as the size of the rotation angle. Specifically, when one main controller controls a plurality of sub controllers, the closer to the main controller, the larger the rotation angle of the sub controller; the further away from the master control the secondary controller is, the smaller the rotation angle.

Furthermore, the binding relationship between the master controller and the skeleton can be further established. That is, the secondary controller is given positional and rotational constraints of the bone, and the secondary controller is given rotational and positional constraints to the primary controller to achieve establishing a binding between the primary controller and the bone.

In addition to this, the position constraints and rotation constraints of the master controller are also bound by the overall controller.

In an alternative embodiment, the control strength of each master controller by the master controller is determined according to the distance between each master controller and the master controller.

Specifically, the main controller close to the main controller is controlled by the strongest control force, so that the main controller has the highest control strength on the main controller; the master controller that is far from the master controller receives the weakest control force, and thus the control strength of the master controller on the master controller is the smallest.

The magnitude of the control intensity can be added by a value of 0-100, and the value decreases in equal proportion from far to near.

In step S240, the motion of the bound bones is controlled according to the master controller, respectively.

In an exemplary embodiment of the present disclosure, after the master controller and the bones are bound, the motion of the bound individual bones may be controlled by the master controller.

Specifically, the master controller can drive the master controller, the secondary controller and the skeleton to move, and the overall movement effect is presented, so that the situation of local displacement or rotation is avoided. The primary controller may move individually and the secondary controller may follow the primary controller to move uniformly. With the addition of a controller, the bone does not move or rotate alone.

The following describes the control method of the snake-shaped virtual object in the embodiment of the present disclosure in detail with reference to an application scenario.

Fig. 4 shows an effect diagram of setting up a main controller under an application scenario, as shown in fig. 4, the main controller 410 is located at a junction of a head and a body part of a serpentine virtual object, the main controller 420 and the main controller 430 are located at a junction of a limb and the body part, and the like.

Fig. 5 shows an effect diagram of further setting up a main controller in an application scenario, as shown in fig. 5, a distance between the main controller 420 and the main controller 430 is large, and the main controller 440 and the main controller 450 may be added continuously according to an equal division principle.

Fig. 6 is a schematic diagram illustrating an effect of generating a secondary controller in an application scenario, and as shown in fig. 6, after the primary controllers of the snake-shaped virtual object are erected, the secondary controller may be generated to further transition the connection between the primary controllers.

Specifically, the manner in which the secondary controllers are generated may be such that the distance between the target primary controller and the neighboring primary controller is equally determined. That is, two secondary controllers, respectively secondary controller 610 and secondary controller 620, may be generated between primary controller 410 and primary controller 420; secondary controller 630 and secondary controller 640 may be generated between primary controller 420 and primary controller 440; a secondary controller 650 may be generated between the primary controller 440 and the primary controller 430; secondary controller 660 may be generated between primary controller 430 and primary controller 450.

Fig. 7 is a schematic diagram illustrating the effect of erecting a bone in an application scene, and as shown in fig. 7, when the head part is the target part, the corresponding bone can be erected with the neck as the axis. The direction of the frame may be a forward direction of the central axis of the target portion.

When the target part is a body part, since the central axis of the body part is in the horizontal direction, it can be determined that the direction of the skeleton to be erected is the vertical direction. More than two bones can be erected for a body part, and the center point of the body part is taken as a starting point. The center point may be determined from the model highest and lowest points of the body part, i.e. the center point is the center of the model highest and lowest points.

Therefore, the body part can be erected with more than two bones in the vertical direction for the body part by taking the central point as a starting point and taking the preset interval distance as the interval size. And more than two bones are erected to flexibly control the movement of the body part, so that the free twisting of the snake-shaped virtual object is met.

When the target site is a tail site, the bone chain may be erected with a key point of the bone chain as a center of a circle, and the direction of erection may be a direction rearward of a central axis of the tail site. That is, a plurality of bones may be erected for the tail portion to form a bone chain.

Fig. 8 is a schematic diagram illustrating the effect of erecting a skeleton at the tail part in an application scene, and as shown in fig. 8, in addition to erecting a skeleton chain at the tail part, a skeleton may be erected at the tail part in the backward direction of the central axis. This approach is suitable for the case where the snake-shaped virtual object is small in size or the snake-shaped virtual object is not focused on by the animation effect.

Fig. 9 is a schematic diagram illustrating an effect of the control method of the serpentine virtual object in the application scene, as shown in fig. 9, two

secondary controllers

930 and 940 are established between the two

main controllers

910 and 920, and the two

secondary controllers

930 and 940 equally divide the distance between the two

main controllers

910 and 920. When the distance between the two

main controllers

910 and 920 is elongated from 2 meters to 4 meters, the distance of the middle secondary virtual body also changes correspondingly, and the two

secondary controllers

930 and 940 still equally divide the two

main controllers

910 and 920.

On one hand, a plurality of bones are erected towards a target direction on a target part, so that the movement of the snake-shaped virtual object is flexibly controlled, and the requirement of flexibly twisting the snake-shaped virtual object is met; on the other hand, a main controller is erected at the key position of the target part, and the controller controls the rotation and displacement of the corresponding skeleton, so that the control difficulty of the snake-shaped virtual object is reduced, and the control effect of the snake-shaped virtual object is optimized.

Further, in an exemplary embodiment of the present disclosure, there is also provided a control apparatus of a serpentine virtual object. Fig. 10 shows a schematic structural diagram of a control device of a serpentine virtual object, and as shown in fig. 10, the control device 1000 of the serpentine virtual object may include: an object segmentation module 1010, a bone erection module 1020, a relationship binding module 1030, and a bone motion module 1040.
