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.
In the related art, when the length of any part of the body is changed, the bone cannot be only subjected to uniaxial scaling on the part, so that the bone is deformed. For example, when the forearm bone length needs to be reduced, the entire forearm bone X, Y, Z needs to be reduced in three axial directions. When the large arm moves, such as lifting, Y, Z has a rotation angle in the axial direction, therefore, the bone scaling effect will follow the rotation angle in the axial direction Y, Z to deform. As shown in FIGS. 1 a-1 c, the same action will produce different length and thickness arm effects.
In the embodiment of the application, in order to overcome the technical problem that bones cannot be adjusted uniaxially in the related technology, the adjustment bones are implanted into the regional bones, that is, adjustment bones xxx _ Adjust (xxx is the name of the regional bones) are added into the subset bones of each regional bone, and the length, thickness, position and the like of each bone can be independently modified through the combined adjustment of the regional bones and the adjustment bones, so that the free change of the animation model body is realized.
First, a method for processing an animation model skeleton according to an embodiment of the present invention is described below.
Fig. 2 is a flowchart of a method for processing an animation model skeleton according to an embodiment of the present disclosure. As shown in fig. 2, the method comprises the steps of:
step S11, determining a subset skeleton corresponding to a region skeleton to be adjusted in the animation model, wherein the subset skeleton comprises an adjusting skeleton, and the adjusting skeleton is bound with the animation model and inherits the coordinates of the region skeleton;
step S12, acquiring a first adjusting parameter corresponding to a first adjusting operation of regional bones;
step S13, determining a second adjusting parameter for adjusting the bone according to the first adjusting parameter;
and step S14, executing a second adjusting operation on the adjusting bone according to the second adjusting parameter.
Through the steps S11 to S14, when only one or two coordinate axes of the bone need to be adjusted, after the regional bone is adjusted as a whole, the other axes can be restored by adjusting the bone, so that the adjustment of the bone in the required axis is realized, deformation occurs when the bone is prevented from moving, and free change of the body of the animated model is realized. And moreover, because the animation model is bound with the adjusting skeleton, the adjusted skeleton can adapt to animation movement and interaction effect.
Fig. 3 is a schematic skeleton level diagram provided in an embodiment of the present application. As shown in fig. 3, in step S11, each region bone has its corresponding subset bone, the subset bone includes the adjustment bone corresponding to the region bone, if there is a sub-bone in the region bone, the subset bone also includes a sub-bone, and the sub-bone also has its corresponding adjustment bone and sub-bone, … …
For example, regional bone A, B and Head bone Head are both the children of Root bone Root. Wherein the subset of regional bones a includes: the adjustment skeleton a _ Adjust of the region skeleton, and the sub-skeleton a _1 of the region skeleton a, the sub-skeleton a _1 also has its corresponding adjustment skeleton a _1_ Adjust.
The subset of regional bones B includes: the adjustment bone B _ Adjust of the regional bone, and the sub-bone B _1 of the regional bone B, the subset bone of the sub-bone B _1 comprising: regulating skeleton B _1_ Adjust and sub-skeleton B _2, and sub-skeleton B _2 also has its corresponding regulating skeleton B _2_ Adjust.
The subset skeleton of the Head skeleton Head includes the Head adjustment skeleton Head _ Adjust, while the facial skeletons C _1, C _2, and C _3 serve as the subset skeleton of the Head adjustment skeleton Head _ Adjust. Facial bones include the bones of the eyes, nose, mouth, etc.
And the adjusting skeleton inherits the coordinates of the skeleton in the corresponding area and is bound with the animation model.
Optionally, the bone is adjusted to be the bone of the regional bone, aligned with the CS bone of the regional bone.
The animation model has a skeleton structure formed by mutually connected animation skeletons, and generates animation for the model by changing the orientation and the position of the bone skeletons.
The CS skeleton, Character Studio, is a very important plug-in module for 3DS MAX to simulate the actions of humans and bipedal animals.
The adjustment bones are aligned with the CS bones, and the adjustment bones are scaled to conform to the CS bones size and moved to the same location as the CS bones.
Fig. 4 is a flowchart of a method for processing an animation model skeleton according to another embodiment of the present application. As shown in fig. 4, when the first adjustment operation in step S12 is a zoom operation, the first adjustment parameter includes a zoom factor in each coordinate axis of the regional bone; the above step S13 includes the following steps:
step S21, reversely obtaining a second scaling factor of the adjusting bone in the first coordinate axial direction according to the first scaling factor of the regional bone in the first coordinate axial direction, wherein the first coordinate axial direction comprises one coordinate axial direction or two coordinate axial directions of the regional bone, and the scaling operation of the regional bone and the adjusting bone in the first coordinate axial direction is opposite;
and step S22, obtaining a second adjusting parameter according to the first coordinate axis and the second scaling factor.
Wherein, as an alternative, the second scaling factor may be smaller than the first scaling factor.
For example, when it is desired to enlarge the length of the regional bone a, the first adjustment operation is an enlargement operation in which the regional bone a is enlarged in its entirety in the direction of the X, Y, Z three coordinate axes, the bone length in the X-axis direction, the bone thickness in the Y, Z axis direction, and the overall magnifications in the three axes are all the same.
In order to realize the length of the bone A only in the enlargement area, the bone A _ Adjust needs to be controlled and adjusted to perform the reduction operation in the Y, Z axial direction, and the reduction factor in the Y, Z axial direction can be slightly smaller than or equal to the integral magnification factor in three axes.
After the operation of enlarging the skeleton A in the combined region and the operation of reducing the adjusting skeleton A _ Adjust in this way, the skeleton A in the region is only lengthened in length and the thickness of the skeleton is not changed as a whole, so that the uniaxial adjustment of the skeleton is realized, and the free change of the body of the animation model is realized. And moreover, because the animation model is bound with the adjusting skeleton, the adjusted skeleton can adapt to animation movement and interaction effect.
For another example, when it is necessary to Adjust only the thickness of the regional bone B, the variation in the Y, Z axial direction of the adjustment bone B _ Adjust of the regional bone B can be adjusted only. For example, when scaling the thickness of the abdominal bone Abdomen, it is possible to Adjust the bone Abdomen _ Adjust only in the Y, Z axis direction.
Fig. 5a is a schematic diagram of the forearm skeleton before adjustment according to the embodiment of the present application. FIG. 5b is a schematic diagram of the forearm bone after uniaxial scaling according to the embodiment of the present application. Through comparison, the length of the large arm can be freely adjusted according to the needs of a user, and the thickness of the large arm is basically not changed.
Fig. 6a is a schematic view of an abdominal bone provided in an embodiment of the present application before adjustment. Fig. 6b is a schematic view of the abdominal bone Y, Z provided in an embodiment of the present application after axial scaling. By contrast, it has been found that it is possible to change only the thickness of the abdominal bones without simultaneously adjusting their length.
In an alternative embodiment, the subset bone further comprises a sub-bone of the region bone. The method further comprises the following steps:
step A1, determining a third adjusting parameter of the skeleton according to the first adjusting parameter;
and step A2, performing a third adjustment operation on the sub-skeleton according to the third adjustment parameter.
In this embodiment, when the bone of the region changes, the related sub-bones also need to be changed correspondingly in order to improve the authenticity of the bone change.
Optionally, when the first adjustment operation is a zoom operation, the step a1 includes:
step B1, obtaining a third zoom multiple of the sub-skeleton according to the first zoom multiple of the zoom operation of the regional skeleton, wherein the zoom operation of the regional skeleton and the sub-skeleton is opposite;
and step B2, obtaining a third adjusting parameter according to the third scaling factor.
For example, a subset of the large Arm bones Arm includes: the Forearm bone Forearm and the large Arm bone Arm _ Adjust. When the length of the big Arm bone needs to be lengthened, if the magnification is 1.5 times, the big Arm bone Arm is firstly enlarged 1.5 times in the X, Y, Z axial direction as a whole, the adjusting bone Arm _ Adjust is reduced 1.45 times in the Y, Z axial direction, and the small Arm bone Forearm is reduced 1.5 times in the X, Y, Z axial direction as a whole.
When the Forearm bone length is reduced, for example, by 0.2 times the original length, the Forearm bone Arm is first reduced by 0.2 times in the X, Y, Z axial direction as a whole, the adjustment bone Arm _ Adjust is enlarged by 0.19 times in the Y, Z axial direction, and the Forearm bone Forearm is enlarged by 0.2 times in the X, Y, Z axial direction as a whole.
For another example, when the thickness of the abdominal bone Abdomen is zoomed, the adjustment bone Abdomen _ Adjust may be adjusted only in the Y, Z axial direction, and the Pelvis bone Pelvis and the sternum bone sternum of the abdominal bone Abdomen may be adjusted according to the zoom factor of the abdominal bone Abdomen.
In a further alternative embodiment, the first adjustment parameter comprises a displacement parameter when the first adjustment operation is a displacement operation. The step a1 includes:
step C1, determining a second coordinate axial direction of the regulating sub-skeleton and a fourth scaling multiple in the second coordinate axial direction according to the displacement parameters;
and step C2, determining a third adjustment parameter of the sub-skeleton according to the fourth scaling factor.
For example, when the width of the shoulder bone changes, the shoulder bone may be displaced, and the width of the chest bone may be changed by scaling the thickness of the chest bone based on the displacement of the shoulder bone.
Fig. 7a is a schematic diagram of a shoulder bone provided in an embodiment of the present application before adjustment. Fig. 7b is a schematic view of the displaced shoulder bone according to the embodiment of the present application. By contrast, as the shoulder bone is displaced to be widened, the thoracic bone is correspondingly enlarged Y, Z in the axial direction, so that the thoracic bone is widened.
In an alternative embodiment, when the sub-bones of the regional bone are adjusted, they may also be adjusted only uniaxially. Fig. 8 is a flowchart of a method for processing an animation model skeleton according to another embodiment of the present application. As shown in fig. 8, the method further comprises the steps of:
step S31, acquiring a sub-adjustment skeleton corresponding to the sub-skeleton, and binding the sub-adjustment skeleton with the animation model and inheriting the coordinates of the sub-skeleton;
step S32, determining a third coordinate axial direction of the sub-skeleton except the second coordinate axial direction, wherein the zoom multiple of the sub-skeleton in the third coordinate axial direction is a fourth zoom multiple;
step S33, reversely obtaining a fifth scaling factor of the sub-adjusting skeleton in the third coordinate axial direction according to the fourth scaling factor of the sub-skeleton in the third coordinate axial direction;
step S34, determining a fourth adjusting parameter of the sub-adjusting skeleton according to the third coordinate axis and the fifth scaling factor;
and step S35, executing a fourth adjusting operation on the sub-adjustment bones according to the fourth adjusting parameter.
For example, as shown in fig. 3, when the regional bone B is enlarged in the X-axis direction, and the sub-bone B _1 is correspondingly reduced in the X-axis direction, the sub-bone B _1 can be firstly reduced in the X, Y, Z-axis direction as a whole, and then the adjustment bone B _1_ Adjust is enlarged in the Y, Z-axis direction, so that the sub-bone B _1 is reduced in the Y, Z-axis direction in a uniaxial direction. Similarly, when the sub-bone B _1 is contracted in the X-axis direction, the sub-bone B _2 can be enlarged in the Y, Z-axis direction, and only the adjustment bone B _2_ Adjust of the sub-bone B _2 is enlarged in the Y, Z-axis direction. Thus, the overall adjustment of the regional skeleton and its individual sub-skeletons is achieved.
