Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terms "first," "second," "third," "fourth," and the like in the description and in the claims of the present application and in the above-described drawings (if any) are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

At this stage, in order to make the animated objects in the 3D game more realistic and lively, the remodelling and muscles at the joints are handled by fusion morphing (vertex animation), in particular: binding is carried out by a set of character model files, weight is processed, specific actions with larger angles are made for the model, a skin morph command is added, bones of a certain specific action are added into the skin morph (only one joint can be made at one time), and then points of the model are directly adjusted to make joint deformation and muscle effects required by the user.

However, this approach has the following problems: firstly, the manufacturing of the method must be carried out under a certain specific action, if the action is too large, the points of the model at the joint are overlapped, the manufacturing personnel are inconvenient to manufacture the modification of the joint, the manufacturing time is long, the method must be carried out under the specific action, and when the action exceeds the amplitude of the action, the modification effect cannot be realized; secondly, if each animation object uses skin morph to make modification and muscle effect, the making cost is high; and thirdly, the existing file export type does not support the files with the modification type and the muscle effect which are produced in the mode, and even if the files can be exported, the existing game engine does not support the modification type and the muscle effect which are produced in the mode.

In order to solve the problems, the application provides a processing method of an animation object, the shape of the animation object is modified by covering the telescopic modified skeleton, the problem that the shapes of joints between a target part and other parts are lost in the motion process is solved, compared with the prior art, the shape modifying step is simplified, and the manufacturing cost of the animation object is reduced.

The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 1 is a flowchart illustrating a processing method of an animation object according to an embodiment of the present application, where an execution main body of the embodiment may be a processing device of the animation object, and the processing device may be integrated in a terminal, a server, or other devices capable of executing animation object production, and the embodiment is not limited thereto. As shown in fig. 1, the method in this embodiment may include:

s101, a rotation command for the target part of the animation object is acquired.

And S102, responding to the rotation instruction, and controlling the first auxiliary object to move according to the rotation constraint between the target part and the first auxiliary object.

The animation object is an object of any motion in any game, and the target portion is a portion where the animation object bends during motion, such as a thigh, a calf, a forearm, and the like, which is not limited in this embodiment.

In practical applications, when the animated object moves, for example, runs, the lower leg of the animated object bends, and the target region is the lower leg. Wherein the flexion of the lower leg is essentially a rotation of the lower leg. Generally, when the lower leg rotates, there is a problem of missing body in the knee joint between the lower leg and the thigh, fig. 2 is a schematic diagram of a knee joint provided in the present application, and as shown in fig. 2, the body in the knee joint 200 between the lower leg and the thigh is missing, so that the body in the knee joint 200 does not conform to the shape of the real exercise.

In this way, in order to solve the problem that the lower leg of the animation object causes the loss of the body shape of the knee joint when bending, in the present embodiment, a rotation instruction for the target portion is acquired, and in response to the rotation instruction, the first auxiliary object is controlled to move in accordance with the rotation constraint between the target portion and the first auxiliary object provided at the joint between the target portion and the other portion of the animation object. The first auxiliary object is used for assisting in shaping the missing body at the joint.

Referring to the example of fig. 2, the first auxiliary object is disposed at a knee joint between a thigh and a shank, with a rotational constraint between the target portion and the first auxiliary object, and when the target portion rotates, the first auxiliary object may be controlled to move according to the rotational constraint between the target portion and the first auxiliary object.

Wherein the rotational constraint between the target site and the first auxiliary object comprises: the first auxiliary object follows the constraint relation of the target part rotation. That is, when the target portion rotates, the first auxiliary object rotates following the first auxiliary object.

And S103, controlling the second auxiliary object to move according to the parent-child relationship between the first auxiliary object and the second auxiliary object.

The second auxiliary object is arranged on a tail skeleton of the modified skeleton, the modified skeleton is arranged on the target part, and a paternal-child relationship exists between the modified skeleton and the target part. Optionally, the caudal bone is located on a side of the modified bone proximal to the joint.

Optionally, the modified bone is bone.

For the father-son relationship, taking a tree as an example, when the main trunk of the tree moves, the branches of the tree can move certainly, when a gust of wind blows, the branches can move along with the wind, namely, the branches (namely, the son) can move along with the movement of the main trunk (namely, the father), the branches can also move relatively independently, in 3D game software (for example, 3dmax), the son can be selected first, then the father-son link option is clicked, and then the father is selected, so that the father-son relationship is established.

It should be noted that, since the priority of the rotation constraint is higher than the parent-child relationship, when the target portion rotates, the first auxiliary object will follow the motion, and the modified skeleton will not follow the motion. The paternal-to-child relationship between the modified bone and the target site is referred to herein to illustrate that the modified bone and the target site are bound together.

In this embodiment, when the first auxiliary object moves, the second auxiliary object moves following the first auxiliary object with the first auxiliary object as a parent and the second auxiliary object as a child according to the parent-child relationship between the first auxiliary object and the second auxiliary object.

And S104, performing stretching treatment on the modified skeleton according to the constraint relation between the second auxiliary object and the modified skeleton.

And S105, performing skinning operation according to the processed modified skeleton to obtain a skinned animation object.

Wherein the constraint relationship between the second auxiliary object and the modified skeleton comprises a position constraint relationship and/or a gaze constraint relationship.

The position constraint relationship means that when the position of the constrained object changes, the position of the constrained object also changes correspondingly. The gazing constraint means that the constrained object always gazes at the constrained object, and when the constrained object moves, the constrained object also gazes at the constrained object to generate corresponding change.

In this embodiment, the second auxiliary object is a constrained object, and the modified skeleton is a constrained object, and when the second auxiliary object moves, the modified skeleton can be stretched or shortened according to a constraint relationship between the second auxiliary object and the modified skeleton, that is, along with the movement of the second auxiliary object.

And then, performing skinning operation according to the processed modified skeleton to obtain a skinned animation object, wherein the skinning operation refers to the modified skeleton controlling the external contour of the target part of the animation object, and when the modified skeleton stretches or shortens, the external contour of the target part can be controlled through drawing weights in the skinning operation process, so that when the target part rotates, the body missing at the joint between the target part and other parts of the animation object can be restored to the state of the human body. On the basis of the embodiment of fig. 2, fig. 3 is a schematic diagram of another knee joint provided in the embodiment of the present application, and as shown in fig. 3, the knee joint 300 between the lower leg and the upper leg has a normal shape, which conforms to the shape of the human body during real motion.

In a specific implementation, step S105 specifically includes:

a1, controlling the modified skeleton to displace according to the motion of the second auxiliary object and the constraint relation between the second auxiliary object and the modified skeleton;

and A2, performing expansion and contraction treatment on the modified skeleton according to the displacement of the modified skeleton.

When the second auxiliary object moves, the modified skeleton can be controlled to move according to the movement of the second auxiliary object and the constraint relation between the second auxiliary object and the modified skeleton, and then the modified skeleton is stretched or shortened according to the displacement of the modified skeleton, namely, when the modified skeleton moves, the modified skeleton is stretched or shortened substantially.

Further, obtaining the skinned animation object, and making a muscle effect, specifically:

an instruction for adding muscle to a modified bone is received and muscle is added to the modified bone according to the instruction.

After the skinned animation object is obtained, an instruction for adding muscle to the modified skeleton input by a user can be received, and then the muscle is added to the modified skeleton according to the instruction.

Illustratively, the modified bone is bone, and muscle can be added to the modified bone as follows: in 3dmax, the bone skeletal system panel is opened and the modified bone attribute scale is changed to squash, which achieves the muscular effect of the modified bone. The modified skeleton and the target part are bound together, so that the muscle effect of the target part of the animation object is realized. Fig. 4 is a schematic view of a muscle effect provided by the embodiment of the application, and as shown in fig. 4, the target part is a lower leg, and after the muscle effect is made on the modified skeleton on the lower leg, the animation object looks richer and more vivid.

The method for processing the animation object provided by the embodiment comprises the following steps: the method comprises the steps of obtaining a rotation instruction for a target portion of an animation object, responding to the rotation instruction, and controlling the motion of a first auxiliary object according to rotation constraint between the target portion and the first auxiliary object, wherein the first auxiliary object is arranged at a joint between the target portion and other portions of the animation object, and the motion of a second auxiliary object is controlled according to a paternal-child relationship between the first auxiliary object and the second auxiliary object, the second auxiliary object is arranged on a tail bone of a shaping bone, the shaping bone is arranged on the target portion, the paternal-child relationship exists between the shaping bone and the target portion, stretching processing is carried out on the shaping bone according to the constraint relationship between the second auxiliary object and the shaping bone, and skinning operation is carried out according to the processed shaping bone to obtain the skinned animation object.

And S202, converting the displacement value of the modified skeleton into a copied scaling value of the modified skeleton through the script controller.

S203, performing expansion and contraction processing on the modified skeleton according to the zoom value.

In practical applications, the animation object created in the above manner may not be loaded into some game engines, and thus, these game engines may not recognize the displacement value of the modified skeleton, and therefore, in this embodiment, in order to be applied to various game engines, the modified skeleton is copied and the copied modified skeleton is set on the target portion, where the modified skeleton and the copied modified skeleton are overlapped in position, and then a code is written by the script controller to convert the displacement value of the modified skeleton into the scaled value of the copied modified skeleton. And then, stretching the modified skeleton by using the zoom value obtained by conversion.

The target part may be any body part of the animation object, for example: thigh, calf, forearm, etc.

The first auxiliary object is used to assist in reshaping the animated object, and may be created in 3D gaming software (e.g., 3 dmax). Specifically, one animation object is opened using 3dmax, then a first auxiliary object is created, and the first auxiliary object is disposed at a joint between a target portion and another portion of the animation object, specifically, the first auxiliary object is disposed at a joint between the target portion and another portion of the animation object in an axis-aligned manner.

The axis alignment mode means that the coordinate system of the first auxiliary object and the coordinate system of the target part are completely overlapped, and the axis of the first auxiliary object and the axis of the knee joint are overlapped.

The first auxiliary object is used for assisting in modifying the animation object.

Exemplarily, fig. 7 is a schematic view of a lower leg provided in an embodiment of the present application, as shown in fig. 7, a first auxiliary object 700 is disposed at a knee joint between the lower leg and an upper leg, a modified bone 701 is disposed on the lower leg, a coccyx 7011 of the modified bone 701 is close to the knee joint, and a second auxiliary object 702 is disposed on the coccyx.

Specifically, a parent-child relationship is established in which the target portion is a parent and the modified skeleton is a child, and a parent-child relationship is established in which the first auxiliary object is a parent and the second auxiliary object is a child.

In 3D game software (such as 3dmax), when a parent-child relationship is established, a child can be selected first, then a parent-child link option is clicked, and then a parent is selected, so that the parent-child relationship is established.

Wherein, establishing a constraint relationship between the second auxiliary object and the modified skeleton comprises:

The position constraint relationship refers to that when the position of the constrained object changes, the position of the constrained object also changes correspondingly. The gazing constraint means that the constrained object always gazes at the constrained object, and when the constrained object moves, the constrained object also gazes at the constrained object to generate corresponding movement. In this embodiment, the second auxiliary object is a constrained object, and the modified skeleton is a constrained object.

In 3dmax, options of "position constraint" and "gaze constraint" may be set, and a user may select the second auxiliary object, then select "position constraint", and then select the middle modified skeleton, so that a position constraint relationship in which the second auxiliary object is a constrained object and the modified skeleton is a constrained object is established.

Similarly, a second auxiliary object is selected, then the 'gaze constraint' is selected, and then the modified skeleton is selected, so that the gaze constraint relation that the second auxiliary object is the constrained object and the modified skeleton is the constrained object is established.

It should be noted that L ookat under the upnp control may be selected when the "gaze constraint" is selected, so as to avoid a sudden 180 degree reversal of the modified bone when the target site is rotated.
