step S11, acquiring a first original animation model;
step S12, according to the simplification strategy, executing the simplification operation of the first original animation model to obtain a first simplified animation model;
in step S13, the first simplified animation model is rendered.
Optionally, the simplification strategy may include presetting the skeleton to be deleted, and may also include a simplification level for the animation model.
Through the steps S11 to S13, after the face/person pinching is completed, the animation model is simplified, the bone data amount in the animation model is reduced, the calculated amount in the rendering process is reduced, the calculating speed is increased, and the game fluency is optimized.
Fig. 2 is a flowchart of an animation model processing method according to another embodiment of the present application. As shown in fig. 2, the step S12 includes the following steps:
step S21, obtaining skeleton data corresponding to the first original drawing model;
step S22, assigning vertex information corresponding to the bone data to the vertex of the original animation model;
in step S23, modified skeleton data corresponding to the reduction policy is deleted from the skeleton data.
Through the steps S21 to S23, after the face-pinching/person-pinching is completed, the animation model is simplified, the vertex information corresponding to the skeleton data is assigned to the vertex of the original animation model, and the set face-pinching/person-pinching skeleton, including the modification parameters corresponding to the skeleton, is deleted, so that the animation model obtained through rendering is the model after the face-pinching/person-pinching, the skeleton amount of the animation model is reduced, the calculation amount is reduced in the rendering process, the calculation speed is increased, and the game fluency is optimized.
In this embodiment, a simplified control may be provided, and the control may be in the form of a slide bar, a knob, or the like. By simplifying the controls, the simplification operations can be turned on or off, and the level of simplification can also be adjusted.
The step S12 further includes: determining the simplification level of the first original animation model according to the adjustment operation of the simplification control; and determining the adjusted bone data corresponding to the simplification level.
Fig. 3a and fig. 3b are schematic diagrams of a simplified control provided in an embodiment of the present application when the simplified control is closed and opened, respectively. The simplified control may be a knob, as shown in fig. 3a, which is in an off state when the knob 31 is upright. As shown in fig. 3b, when the knob 31 is horizontal, the simplified control is in the on state.
Fig. 3c is a schematic diagram of an associated adjustment control according to another embodiment of the present application. As shown in fig. 3c, the simplified control is provided with at least one shift 32. When the knob 31 is rotated to the shift position 32, the animation model is simplified according to the simplification level corresponding to the shift position 32.
Optionally, the simplified control may be provided with a plurality of gears, the simplified level corresponding to the gear 1 is 1, and 30% of the bone data is deleted; the simplification level corresponding to the gear 2 is 2, and 50% of bone data are deleted; the reduction level corresponding to gear 3 is 3, and 70% of the bone data is deleted.
In an alternative embodiment, the simplification policy is automatically adjusted from processor to processor. The method further comprises the following steps: acquiring performance parameters of equipment for executing rendering; and determining a simplification strategy according to the performance parameters.
Wherein the apparatus to perform rendering may include: graphics Processing Unit (GPU), Central Processing Unit (CPU), and so on.
Wherein the performance parameters of the GPU include at least one of: the number of cores, the core frequency, the video memory bit width, the video memory frequency, the video memory size and the like.
The performance parameters of the CPU include at least one of: frequency, cache capacity, operating voltage, bus style, manufacturing process, superscalar, etc.
According to the performance parameters of the equipment, the performance grade or performance score corresponding to the equipment can be calculated, and the simplification strategy can be determined according to the performance grade or performance score. When the device performing the rendering includes at least two, an average of the performance levels or performance scores of the at least two devices may be calculated, and the simplification policy may be determined based on the average.
Based on performance parameters of a GPU or a CPU and the like, whether a simplified control needs to be started or not can be determined, and if the simplified control is started, the simplification level of the animation model, such as the percentage of deleted skeleton data, can be determined according to the performance parameters.
In an alternative embodiment, whether the simplified control needs to be opened or not can be determined according to the number of the animation model needing to be rendered in the same screen or the number of bones (or the amount of bone data) needing to be rendered, and the simplification level of the animation model after the simplified control is opened. For example, when the number of animation models needing to be rendered under the same screen is 1-3, the simplified control is not started, and when the number of animation models under the same screen is 4 or more, the simplified control is started. When the number of animation models under the same screen is 4-6, a simplification strategy of a simplification level 1 is adopted, and 30% of skeleton data of each animation model is deleted; when the number of animation models under the same screen is 7-9, a simplification strategy of a simplification level 2 is adopted, and 50% of skeleton data of each animation model is deleted; when the number of the animation models under the same screen is 10 or more, 70% of the skeletal data of each animation model is deleted by adopting the simplification strategy of the simplification level 3.
In an alternative embodiment, the reduction policy may also be controlled by the user whether to turn on, and the user may also select the reduction level as desired.
In this embodiment, after the simplification operation is performed on the animation model, the original animation model is not deleted, but the simplified animation model is rendered, and the original animation model is stored in the server, so that the animation model can be modified again in the following process.
FIG. 4 is a flowchart of a method for processing an animation model according to another embodiment of the present application. As shown in fig. 4, the method comprises the steps of:
step S31, storing the first original animation model in the server;
step S32, when receiving the first adjustment operation of the first simplified animation model, obtaining a first original animation model from the server;
step S33, executing a first adjustment operation on the first original animation model to obtain a second original animation model;
step S34, according to the simplification strategy, executing the simplification operation of the second original animation model to obtain a second simplified animation model;
step S35, rendering the second simplified animation model;
in step S36, the second original animated model is stored in the server.
Alternatively, the simplification policy in the above step S34 may be the same as or different from the simplification policy in the above step S12.
Through the steps S31 to S36, when the adjustment operation on the first simplified animation model is received, the first original animation model which is not simplified is obtained from the server, the simplification operation is performed on the first original animation model, the rendering is performed on the second simplified animation model, and the second original animation model which is adjusted on the first original animation model is still stored on the server.
In this embodiment, when the animation model is adjusted, since a certain association relationship exists between bones, when the current bone is adjusted, other bones related to the current bone can be adjusted.
FIG. 5 is a flowchart of a method for processing an animation model according to another embodiment of the present application. As shown in fig. 5, the step S33 includes:
step S41, determining a current skeleton corresponding to the first adjustment operation and an adjusted skeleton corresponding to the current skeleton;
step S42, acquiring a first weight corresponding to the current skeleton and adjusting a second weight corresponding to the skeleton;
step S43, determining a second adjustment parameter corresponding to the adjusted bone according to the first adjustment parameter, the first weight and the second weight corresponding to the first adjustment operation;
and step S44, executing a second adjustment operation on the adjusted bone according to the second adjustment parameter.
In this embodiment, when a user adjusts one of the bones, the adjustment bone corresponding to the bone also performs a corresponding adjustment operation, so as to achieve synchronous adjustment of the bones and the related bones thereof, and quickly and accurately adjust the animation model according to the user's needs. Meanwhile, the user does not need to manually adjust each skeleton one by one, and other related skeletons can be synchronously adjusted only by adjusting one skeleton, so that the complexity of skeleton adjustment operation is reduced.
For the mutually related bones, each bone has a corresponding weight, and the weight represents the corresponding adjustment relation of each bone in the adjustment process. For example, each skeleton is divided into 31 gears of-15 to 15 according to original skeleton data, the weight of the current skeleton a is 0.6, and the weight of the associated skeleton B is 1.2, and each time the current skeleton a adjusts 0.6 gear, the associated skeleton B adjusts 1.2 gear. If the current bone a is adjusted 3 gears from the initial position, the associated bone B is adjusted 3 × 1.2 ÷ 0.6 ═ 6 gears.
The weight may be an adjustment relationship between actual bone data, including a relationship between adjustment parameters such as a rotation angle and a displacement distance, that is, the adjustment parameter is directly calculated according to the bone data of the current bone, and the adjustment parameter corresponding to the associated bone is calculated according to the weight of each bone, which is not described herein again.
In an alternative embodiment, the adjustment facial skeleton range corresponding to the current facial skeleton may be determined according to the turning on or off of the associated adjustment control. The above step S41 includes the following steps: acquiring a control state of the associated adjusting control; when the control state is an opening state, determining that the adjustment skeleton comprises a current skeleton and a related skeleton of the current skeleton; and when the control state is the closing state, determining that the bone is adjusted to be the current bone.
For example, for bones corresponding to an eye, when the associated condition control is closed, and the user adjusts the "right eye socket" bone, the other bones "right inner canthus," "right outer canthus," "left eye socket," "left inner canthus," and "left outer canthus" are not adjusted in association. Only when the associated condition control is on will the associated bone of the "right eye socket" adjust synchronously.
Optionally, when the control state is the open state, the control state further includes an association range level; the step S41 further includes: and determining the related bone of the current bone according to the related range level.
For example, for the bones corresponding to the eye, when the association range level is one level, the user adjusts the bones of the "right eye socket", only the "right inner corner of the eye" and the "right outer corner of the eye" bones follow the adjustment, while the bones of the "left eye socket", "left inner corner of the eye" and "left outer corner of the eye" remain unchanged.
Optionally, a plurality of gears may be further set on the associated adjustment control, and the associated skeleton ranges corresponding to different gears are different. For example, for the bones of the eye, the associated bones corresponding to the gear 1 are all the bones of the eye; the related bones corresponding to the gear 2 comprise nasal bones besides all bones of the eyes; the associated bones corresponding to gear 2 include the mouth bones in addition to all the bones of the eye and the nose bones.
In the above embodiment, each gear of the association adjustment control is associated with a tree-shaped bone data selection range. When the associated adjusting control is started, reading all the sub skeletons of the current skeleton; when the associated adjustment control is closed, only the current bone is read; when the associated regulating control is in a certain gear, reading the sub-skeleton corresponding to the range of the gear. In the process of adjusting the skeleton, the father skeleton of the current skeleton is not affected generally, but the father skeleton can be controlled to make corresponding follow-up adjustment when the specific skeleton is adjusted according to the requirement.
In an alternative embodiment, when adjusting multiple associated bones, each bone needs a uniform initial state, i.e. multiple bones are adjusted from the same initial state. The step S44 includes: acquiring an intermediate gear and a parameter adjusting range corresponding to the associated skeleton, wherein the intermediate gear of the current skeleton is the same as that of the associated skeleton; and determining a second adjusting parameter corresponding to the second adjusting gear according to the intermediate gear and the parameter adjusting range.
When a plurality of associated bones are adjusted, the initial state of each bone, namely the intermediate state of each bone, needs to be synchronized, so that each associated bone can be uniformly adjusted subsequently. FIG. 6 is a flowchart of a method for processing an animation model according to another embodiment of the present application. As shown in fig. 6, the method further includes the step of determining the intermediate gear of each bone, which is as follows:
step S51, acquiring a first parameter adjusting range of the current skeleton, a second parameter adjusting range of the associated skeleton and the gear number of the first adjusting component and the second adjusting component;
step S52, determining a first original gear corresponding to the current bone original bone data according to the first parameter adjusting range and the gear number, and determining a second original gear corresponding to the associated bone original bone data according to the second parameter adjusting range and the gear number;
in step S53, an intermediate gear is calculated according to the first original gear, the second original gear, the first weight and the second weight.
The process of determining the intermediate gear will be described in detail below by way of a specific example.
Each bone is divided into 31 gears of-15 to 15 according to original bone data.
The associated three bones A, B, C, whose original gears were calculated to be-10, 7, 1, respectively, from their original bone data.
If the weight corresponding to the skeleton A, B, C is the same, the intermediate gear is
If the weights corresponding to skeleton A, B, C are 0.6, 1.2, and 0.8, respectively, the intermediate gear is
In this way, the bone A, B, C is adjusted with the same middle gear as a starting point, and although the initial state is different from the original effect, the error is relatively small, so that the subsequent multi-bone related adjustment is facilitated.
In the embodiment, in order to adjust the skeleton more freely, the user can pinch an exaggerated and abnormal face shape, the user can exert the function freely, and the skeleton is allowed to be adjusted in at least a single axial direction when the skeleton is zoomed in the face pinching process.
In this example, a scaled bone xxx _ Adjust was implanted for the bone (xxx is the bone name of the bone). Fig. 7 is a schematic skeleton level diagram provided in an embodiment of the present application. As shown in fig. 7, each bone has its corresponding subset bone, the subset bone includes the scaled bone corresponding to the bone, if there is a sub-bone, the subset bone also includes a sub-bone, and the sub-bone also has its corresponding scaled bone and sub-bone, … …
For example, bone A, B and Head bone Head are both the children of Root bone Root. Wherein the subset of bones of bone a comprises: the scaled skeleton A _ Adjust of this skeleton, and the sub-skeleton A _1 of this skeleton A, this sub-skeleton A _1 also has its corresponding scaled skeleton A _1_ Adjust.
The subset of bone B includes: a scaled bone B _ Adjust of the bone, and a sub-bone B _1 of the bone B, a subset bone of the sub-bone B _1 comprising: scaling skeleton B _1_ Adjust and sub-skeleton B _2, and sub-skeleton B _2 also has its corresponding scaling 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.
Wherein, the scaling skeleton inherits the coordinates of the corresponding skeleton and is bound with the animation model.
Optionally, the zoom bone is a bone of bone, aligned with a CS bone of 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 zoom bone is aligned with the CS bone, and the zoom bone is scaled to conform to the CS bone size and moved to the same location as the CS bone.
FIG. 8 is a flowchart of a method for processing an animation model according to another embodiment of the present application. As shown in fig. 8, when the second adjustment operation is a zoom operation, the step S44 includes the following steps:
step S61, determining a scaling skeleton corresponding to the adjustment skeleton, binding the scaling skeleton and the animation model and inheriting the coordinates of the adjustment skeleton;
step S62, reversely obtaining a second zoom multiple of the zoomed bone in the first coordinate axial direction according to the first zoom multiple of the zoomed 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 zoomed bone, and the zoom operation of the zoomed bone in the first coordinate axial direction is opposite to that of the zoomed bone;
step S63, obtaining auxiliary adjustment parameters of the zoomed skeleton according to the first coordinate axis and the second zoom factor;
in step S64, the adjustment of the zoom bone is performed according to the auxiliary adjustment parameter.
Wherein the second scaling factor may be less than or equal to the first scaling factor.
For example, when the length of the bone A needs to be enlarged, the bone A is enlarged in the three coordinate axes of X, Y, Z in a whole manner, the length of the bone is enlarged in the X-axis direction, the thickness of the bone is enlarged in the Y, Z axis direction, and the whole magnification on the three axes is the same.
In order to achieve only the length of the bone a, the zoom bone a _ Adjust needs to be controlled to perform the zoom-out operation in the Y, Z axial direction, and the zoom-out factor in the Y, Z axial direction may be slightly smaller than or equal to the overall zoom-out factor in three axes.
Thus, by the enlargement operation of the combined bone a and the reduction operation of the scaled bone a _ Adjust, the bone a is elongated only in length as a whole, and the bone thickness does not change.
For another example, when it is necessary to Adjust only the thickness of the bone B, only the change in the Y, Z axis direction of the scaled bone B _ Adjust of the bone B may be adjusted. For example, when scaling the thickness of the abdominal bone Abdomen, its scaled bone Abdomen _ Adjust may be adjusted only in the Y, Z axis direction.
