Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of 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 apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The terms "first," "second," "third," "fourth" and the like in the description and in the claims of this application and in the above-described figures, if any, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application described herein may be capable of operation in sequences other than those illustrated or described herein, for example. 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 object in the 3D game more realistic, the manicuring and muscles at the joints, in particular, are handled by fusion deformation (vertex animation): binding is performed by a set of character model files with good weight, then specific actions with larger angles are made for the model, skin morph commands are added, bones of one specific action are added into skin morph (only one joint can be made at a time, and the points of the model are directly adjusted to make the joint deformation and muscle effect which are wanted.
However, this approach has the following problems: 1. the method must be carried out under a specific action, if the action is too large, the points of the model at the joint are overlapped, the making personnel is inconvenient to make the repair of the joint, the making time is long, the method must be carried out under the specific action, and when the action exceeds the amplitude of the action, the repair effect cannot be realized; 2. if each animation object uses skin morph to make repair and muscle effect, the making cost is high; 3. the existing file export type does not support the files of the modifications and muscle effects made in this way, and even if the files can be exported, the existing game engine does not support the modifications and muscle effects made in this way.
Aiming at the problems, the application provides a processing method of an animation object, which realizes the modification of the animation object by covering the telescopic modification skeleton, solves the problem that the shape of the joint between the target part and other parts is missing in the motion process, simplifies the modification step, and reduces the manufacturing cost of the animation object compared with the prior art.
The following describes the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a processing method of an animation object according to an embodiment of the present application, where an execution subject of the present 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 creation, which is not limited in the present embodiment. As shown in fig. 1, the method in this embodiment may include:
s101, acquiring a rotation instruction of a target part of an animation object.
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 any object that moves in any game, and the target portion is a portion of the animation object that bends when moving, for example, a thigh, a calf, a thigh, a forearm, or the like, which is not limited in this embodiment.
In practical applications, when the animated object moves, for example, runs, the calf of the animated object bends, and the target area is the calf. Wherein the bending of the calf is essentially a rotation of the calf. In general, when the calf rotates, there is a problem of missing body at the knee joint between the calf and the thigh, and fig. 2 is a schematic diagram of a knee joint according to the embodiment of the present application, and as shown in fig. 2, missing body at the knee joint 200 between the calf and the thigh causes the body at the knee joint 200 to not conform to the shape of the real motion.
Based on this, in order to solve the problem that the lower leg of the animation object causes a loss of shape at the knee joint when bending, in the present embodiment, a rotation instruction for a target portion is acquired, and in response to the rotation instruction, the first auxiliary object is controlled to move in accordance with a 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 the knee joint between the thigh and the calf with a rotation constraint between the target site and the first auxiliary object, and when the target site rotates, the first auxiliary object movement may be controlled according to the rotation constraint between the target site and the first auxiliary object.
Wherein the rotation constraint between the target site and the first auxiliary object comprises: the first auxiliary object follows the constraint relation of the target position rotation. That is, when the target portion rotates, the first auxiliary object rotates following the first auxiliary object.
S103, controlling the second auxiliary object to move according to the father-son relationship between the first auxiliary object and the second auxiliary object.
The second auxiliary object is arranged on the tail bone of the modified bone, the modified bone is arranged on the target part, and a father-son relationship exists between the modified bone and the target part. Optionally, the tailbone is located on the side of the modified bone that is proximal to the joint.
Optionally, the modified bone is a bone.
For the father-son relationship, taking a tree as an example, when the trunk of the tree moves, the branches of the tree also can move, when a gust of wind blows, the branches move along with the wind, namely, the branches (namely, the child) move along with the movement of the trunk (namely, the father), the branches can also move relatively independently, in 3D game software (such as: 3 dmax), the father-son link option can be selected firstly and then clicked, and then the father is selected, so that the father-son relationship is established.
It should be noted that, because the rotation constraint has a higher priority than the parent-child relationship, when the target portion rotates, the first auxiliary object follows the movement, and the bone is not modified to follow the movement. The existence of a parent-child relationship between the modified bone and the target site referred to herein is intended to illustrate that the modified bone and the target site are bound together.
In this embodiment, when the first auxiliary object moves, the first auxiliary object is used as a parent, and the second auxiliary object is used as a child, according to the parent-child relationship between the first auxiliary object and the second auxiliary object, so that the second auxiliary object moves along with the first auxiliary object.
S104, stretching and retracting the modified skeleton according to the constraint relation between the second auxiliary object and the modified skeleton.
S105, performing skinning operation according to the processed modified bones to obtain skinned animation objects.
Wherein the constraint relation between the second auxiliary object and the modified bone comprises a position constraint relation and/or a gaze constraint relation.
The position constraint relation means that when the position of the constraint object changes, the position of the constrained object also changes correspondingly. Gaze restriction refers to that a restricting object always looks at a restricted object, and when the restricted object moves, the restricting object looks at the restricted object to generate corresponding change.
In this embodiment, the second auxiliary object is a constrained object, and the repair skeleton is a constrained object, and when the second auxiliary object moves, the repair skeleton may be subjected to expansion and contraction according to the constraint relationship between the second auxiliary object and the repair skeleton, that is, the repair skeleton may be stretched or shortened along with the movement of the second auxiliary object.
And then, performing skin operation according to the processed modified skeleton to obtain a skinned animation object, wherein the skin operation refers to that the modified skeleton controls the external contour of a 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 skin operation process, so that when the target part rotates, the lost body at the joint between the target part and other parts of the animation object can be restored to the existing state of a human body. On the basis of the embodiment of fig. 2, fig. 3 is a schematic diagram of another knee joint according to the embodiment of the present application, and as shown in fig. 3, the shape of the knee joint 300 between the lower leg and the thigh is normal, and conforms to the shape of the human body during the actual movement.
In one specific implementation, step S105 specifically includes:
A1, controlling the shaping skeleton to displace according to the motion of the second auxiliary object and the constraint relation between the second auxiliary object and the shaping skeleton;
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 bone can be controlled to displace according to the movement of the second auxiliary object and the constraint relation between the second auxiliary object and the modified bone, and then the modified bone is subjected to expansion and contraction according to the displacement of the modified bone, namely, when the modified bone is displaced, the modified bone is substantially stretched or shortened.
Further, the skinned animated object is obtained, and a muscle effect can be produced, specifically:
an instruction for adding a muscle to the modified bone is received and a muscle is added to the modified bone in accordance with the instruction.
After the skinned animation object is obtained, an instruction for adding muscles to the modified skeleton, which is input by a user, can be received, and then the muscles are added to the modified skeleton according to the instruction.
Illustratively, the modified bone is a bone to which muscle may be added by: in 3dmax, opening the bone system panel, and changing the attribute scale of the modified bone into extrusion square, so that the muscle effect of the modified bone can be realized. Since the repair skeleton and the target portion are bound together, the muscular effect of the target portion of the animation object is also achieved. Fig. 4 is a schematic diagram of a muscle effect provided in the embodiment of the present application, as shown in fig. 4, the target portion is a calf, and after the muscle effect is made on the repair skeleton on the calf, the animation object looks richer and more vivid.
The processing method of the animation object provided by the embodiment comprises the following steps: the method comprises the steps of obtaining a rotation instruction aiming at a target part of an animation object, responding to the rotation instruction, controlling the first auxiliary object to move according to rotation constraint between the target part and the first auxiliary object, wherein the first auxiliary object is arranged at a joint between the target part and other parts of the animation object, controlling the second auxiliary object to move according to a father-son relationship between the first auxiliary object and the second auxiliary object, wherein the second auxiliary object is arranged on a tail bone of a repair bone, the repair bone is arranged on the target part, father-son relationship exists between the repair bone and the target part, performing expansion and contraction processing on the repair bone according to the constraint relationship between the second auxiliary object and the repair bone, and performing skin operation according to the processed repair bone to obtain the skinned animation object. The embodiment has the following beneficial effects: the first auxiliary object is driven to move when the target part is rotated, the second auxiliary object is driven to move when the first auxiliary object moves, the repair skeleton stretches when the second auxiliary object moves, then the stretch repair skeleton is covered to obtain the animation object after the covering, the repair of the animation object is realized by covering the stretch repair skeleton, the problem that the shape of the joint part between the target part and other parts is missing in the moving process is solved, compared with the prior art, the repair step is simplified, and the manufacturing cost of the animation object is reduced.
On the basis of the above embodiment, fig. 5 is a flowchart of a processing method of an animation object according to an embodiment of the present application, as shown in fig. 5, where the processing method includes:
s201, copying the modified skeleton, and setting the copied modified skeleton on the target position.
S202, converting the displacement value of the modified skeleton into a copied scaling value of the modified skeleton through a script controller.
S203, performing expansion and contraction processing on the modified skeleton according to the scaling value.
In practical applications, the animation objects manufactured in the above manner may not be loaded to some game engines, so that, because the game engines cannot identify the displacement values of the modified skeleton, in this embodiment, in order to be suitable for various game engines, the modified skeleton is copied and the copied modified skeleton is set on the target site, where the positions of the modified skeleton and the copied modified skeleton overlap, and then the script controller writes a code to convert the displacement values of the modified skeleton into the scaled values of the copied modified skeleton. And then, performing expansion and contraction treatment on the modified skeleton by adopting the converted scaling value.
The copied modified skeleton and the target part have a parent-child relationship.
