The following first describes a processing method for an animation model according to an embodiment of the present invention.

step S11, a first original animation model is obtained;
step S12, executing the simplifying operation of the first original animation model according to the simplifying strategy to obtain a first simplified animation model;
and step S13, rendering the first simplified animation model.
Optionally, the simplification strategy may include presetting bones to be deleted, and may also include simplifying the animation model.
Through the steps S11 to S13, after face pinching/man 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 improved, and the game smoothness 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 steps of:
step S21, acquiring skeleton data corresponding to a first original animation model;
step S22, assigning vertex information corresponding to the skeleton data to the vertexes of the original animation model;
step S23, deleting the modified bone data corresponding to the simplified strategy from the bone data.
Through the steps S21 to S23, after the face pinching/pinching is completed, the animation model is simplified, vertex information corresponding to skeleton data is assigned to the vertices of the original animation model, the set face pinching/pinching skeleton is deleted, and modification parameters corresponding to the skeleton are included, so that the animation model obtained by rendering is a model after face pinching/pinching, the skeleton amount of the animation model is reduced, the calculated amount in the rendering process is reduced, the calculation speed is improved, and the game smoothness is optimized.
In this embodiment, a control may be provided to simplify the control, which may be in the form of a slide bar, knob, or the like. By means of the simplification control, the simplification operation can be turned on or off, and the level of simplification can also be adjusted.
The step S12 further includes: determining a simplification level of the first original animation model according to the adjustment operation of the simplification control; modified bone data corresponding to the reduction level is determined.
Fig. 3a and 3b are schematic diagrams of a simplified control provided in an embodiment of the present application when closed and open, respectively. The reduced control may be a knob, as shown in fig. 3a, which is turned off when the knob 31 is vertical. When the knob 31 is horizontal, the reduced control is in an on state, as shown in fig. 3 b.
Fig. 3c is a schematic diagram of an associated adjustment control provided in another embodiment of the present application. As shown in fig. 3c, at least one gear 32 is provided on the simplified control. When the knob 31 is rotated to the gear 32, the animation model is simplified according to the level of simplification corresponding to the gear 32.
Optionally, a plurality of gears can be arranged on the simplified control, the corresponding simplified level of the gear 1 is 1, and 30% of bone data is deleted; the corresponding simplification level of the gear 2 is 2, and 50% of bone data are deleted; the corresponding reduction level of gear 3 is 3, and 70% of bone data are deleted.
In an alternative embodiment, the simplification strategy is automatically adjusted from processor to processor. The method further comprises the steps of: acquiring performance parameters of equipment for performing rendering; a simplification strategy is determined based on the performance parameters.
Wherein the device performing rendering may include: graphics processor (Graphics Processing Unit, GPU), central processing unit (Central Processing Unit, CPU), etc.
Wherein the performance parameters of the GPU include at least one of: core number, core frequency, memory bit width, memory frequency, memory size, etc.
The performance parameters of the CPU include at least one of: frequency, buffer capacity, operating voltage, bus mode, manufacturing process, superscalar, etc.
According to the performance parameters of the device, the corresponding performance level or performance score of the device can be calculated, and according to the performance level or performance score, a simplification strategy can be determined. 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 a simplification policy may be determined based on the average.
Based on the performance parameters of the GPU or the CPU, whether the simplification control needs to be started or not can be determined, and if the simplification control needs to be started, the simplification level of the animation model, such as the percentage of the deleted skeleton data, can be determined according to the performance parameters.
In an alternative embodiment, whether the simplification control needs to be opened or not and the simplification level of the animation model after the simplification control is opened can be determined according to the number of animation models required to be rendered or the number of bones (or the bone data amount) required to be rendered under the same screen. For example, when the number of animation models to be rendered under the same screen is 1-3, the simplification control is not turned on, and when the number of animation models under the same screen is 4 or more, the simplification control is turned on. When the number of the animation models under the same screen is 4-6, adopting a simplification strategy of a simplification level 1, and deleting 30% of skeleton data of each animation model; when the number of the animation models under the same screen is 7-9, adopting a simplification strategy of a simplification level 2, and deleting 50% of skeleton data of each animation model; when the number of the on-screen animation models is 10 or more, a simplification strategy of a simplification level 3 is adopted, and 70% of skeleton data is deleted by each animation model.
In another alternative embodiment, the simplification policies may also be controlled by the user to be turned on or not, and the user may also select a level of simplification as desired.
In this embodiment, after the simplified 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 is convenient to modify again later.
Fig. 4 is a flowchart of an animation model processing method according to another embodiment of the present application. As shown in fig. 4, the method comprises the steps of:
step S31, storing a first original animation model in a server;
step S32, when a first adjustment operation of the first simplified animation model is received, acquiring a first original animation model from a server;
step S33, executing a first adjustment operation on the first original animation model to obtain a second original animation model;
step S34, executing the simplified operation of the second original animation model according to the simplified strategy to obtain a second simplified animation model;
step S35, rendering the second simplified animation model;
step S36, the second original animation model is stored in the server.
Alternatively, the simplification strategy in the above step S34 may be the same as or different from the simplification strategy 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 first original animation model is simplified to obtain the second simplified animation model for rendering, and the second original animation model after the adjustment on the first original animation model is still stored on the server, so that the calculated amount of the rendering process is reduced, and the simplified model can be recovered or modified again, thereby improving the usability of pinching faces/pinching people.
In this embodiment, when the animation model is adjusted, because there is a certain association relationship between bones, other bones associated with the current bone can be adjusted when the current bone is adjusted.
Fig. 5 is a flowchart of an animation model processing method according to another embodiment of the present application. As shown in fig. 5, the step S33 includes:
step S41, determining a current bone corresponding to the first adjustment operation and an adjustment bone corresponding to the current bone;
step S42, obtaining 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 bone according to the first adjustment parameter, the first weight and the second weight corresponding to the first adjustment operation;
step S44, a second adjustment operation for adjusting the skeleton is performed according to the second adjustment parameters.
In this embodiment, when a user adjusts one of the bones, the corresponding adjusting bone of the bone also performs a corresponding adjusting operation, so as to realize synchronous adjustment of the bone and the associated bone, and quickly and accurately adjust the effect of the animation model according to the needs of the user. Meanwhile, the user does not need to manually adjust each bone one by one, and other related bones can be synchronously adjusted only by adjusting one bone, so that the complexity of bone adjusting operation is reduced.
For interrelated bones, each bone has its corresponding weight representing the corresponding adjustment relationship of the bones during adjustment. For example, each bone is divided into 31 gears of-15 to 15 according to the original bone data, the weight of the current bone A is 0.6, the weight of the associated bone B is 1.2, and each time the current bone A adjusts 0.6 gears, the associated bone B adjusts 1.2 gears. 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, a displacement distance, etc., that is, the adjustment parameters are directly calculated according to the bone data of the current bone, and the adjustment parameters corresponding to the associated bone are calculated according to the weight of each bone, which is not described herein.
In an alternative embodiment, the adjusted face bone range corresponding to the current face bone may be determined based on the opening or closing of the associated adjustment control. The step S41 includes the steps of: acquiring a control state of an associated adjustment control; when the control state is an open state, determining that the adjustment skeleton comprises a current skeleton and an associated skeleton with the current skeleton; and when the control state is in the closed state, determining to adjust the skeleton to be the current skeleton.
For example, for a bone to which an eye corresponds, when the associated condition control is closed, the user adjusts the "right orbit" bone, and the other bones "right inner canthus", "right outer canthus", "left orbit", "left inner canthus" and "left outer canthus" are not associated with the adjustment. The associated skeleton of the "right orbit" will be adjusted synchronously only when the associated condition control is on.
Optionally, when the control state is an on state, the control state further includes an association range level; the step S41 further includes: and determining the associated skeleton of the current skeleton according to the associated range level.
For example, for a bone to which the eye corresponds, when the associated range level is one level, the user adjusts the bone of the "right eye socket", only the bones of the "right inner eye corner" and the "right outer eye corner" follow the adjustment, while the bones of the "left eye socket", "left inner eye corner" and "left outer eye corner" remain unchanged.
Optionally, a plurality of gears can be further set on the associated adjustment control, and associated bone ranges corresponding to different gears are different. For example, for an eye bone, the associated bone corresponding to gear 1 is all the eye bones; the associated bones corresponding to the gear 2 comprise nose bones besides all bones of eyes; the associated bones corresponding to the gear 2 comprise the bones of the mouth besides all the bones of the eyes and the bones of the nose.
In the above embodiment, each gear of the association adjustment control is associated with the skeletal data selection range of the tree. When the associated adjustment control is opened, reading all the sub-skeletons of the current skeleton; when the associated adjustment control is closed, only the current skeleton is read; when the associated adjusting control is in a certain gear, reading the sub-skeleton of the corresponding range of the gear. In the bone adjustment process, the father bone of the current bone is not affected generally, but the father bone can be controlled to make corresponding following adjustment when adjusting the specific bone according to the requirement.
In an alternative embodiment, when multiple associated bones are adjusted, each bone requires a uniform initial state, i.e., multiple bones begin to adjust from the same initial state. The step S44 includes: acquiring an intermediate gear and a parameter adjusting range corresponding to the related skeleton, wherein the intermediate gear of the current skeleton is the same as that of the related skeleton; and determining a second adjusting parameter corresponding to the second adjusting gear according to the intermediate gear and the parameter adjusting range.
When adjusting a plurality of associated bones, the initial states of the bones, namely the intermediate states of the bones, need to be synchronized, so that the associated bones can be uniformly adjusted later. Fig. 6 is a flowchart of an animation model processing method according to another embodiment of the present application. As shown in fig. 6, the method further includes the step of determining intermediate gear positions of each bone, specifically as follows:
step S51, acquiring a first parameter adjusting range of a current bone, a second parameter adjusting range of a related bone and the gear numbers of a first adjusting component and a second adjusting component;
step S52, determining a first original gear corresponding to the original bone data of the current bone according to the first parameter adjusting range and the gear number, and determining a second original gear corresponding to the original bone data of the related bone according to the second parameter adjusting range and the gear number;
step S53, calculating an intermediate gear according to the first original gear, the second original gear, the first weight and the second weight.
The process of determining the intermediate gear is described in detail below by way of one specific example.
Each skeleton is divided into-15 to 15 total 31 gears according to the original skeleton data.
The associated three bones A, B, C are calculated to have their original gear-10, 7,1, respectively, based on their original bone data.
If the weights corresponding to the bones A, B, C are the same, the intermediate gear is
If the weights corresponding to the skeletons A, B, C are 0.6,1.2,0.8, the intermediate gear is
In this way, the skeleton A, B, C is adjusted by taking the same intermediate gear as a starting point, and the initial state is different from the original effect, but the error is relatively small, so that the subsequent multi-skeleton association adjustment is facilitated.
In this embodiment, in order to more freely adjust the bone, the user may pinch an exaggerated and abnormal face shape, so that the user may freely play the face, and at least one axial adjustment of the bone is allowed when the scaling operation is performed on the bone during the face pinching process.
In this example, a scaled bone xxx_Adjust (xxx is the bone name of the bone) is implanted into the bone. Fig. 7 is a schematic diagram of a bone hierarchy provided in an embodiment of the present application. As shown in fig. 7, each bone has its corresponding subset bone, which subset bone includes the corresponding scaled bone of the bone, and if there is a sub-bone, the subset bone also includes a sub-bone, which sub-bone also has its corresponding scaled bone and sub-bone, … …
For example, bone A, B and Head bone Head are both sub-bones of the Root bone Root. Wherein, subset bones of bone a comprise: the scaling skeleton a_adjust of the skeleton, and the child skeleton a_1 of the skeleton a, the child skeleton a_1 also having its corresponding scaling skeleton a_1_adjust.
Subset bones of bone B include: a scaling skeleton b_adjust of the skeleton, and a sub-skeleton b_1 of the skeleton B, a subset skeleton of the sub-skeleton b_1 comprising: scaling skeleton b_1_adjust and sub-skeleton b_2, while sub-skeleton b_2 also has its corresponding scaling skeleton b_2_adjust.
The subset bones of the Head bone Head include the Head Adjust bone head_adjust, while the face bones c_1, c_2, and c_3 are subset bones of the Head Adjust bone head_adjust. Facial bones include eye bones, nose bones, mouth bones, and the like.
Wherein, the scaling skeleton inherits the coordinates of the corresponding skeleton and is bound with the animation model.
Optionally, the scaled bone is a bone of a bone, aligned with a CS bone of the bone.
Wherein the bone skeleton, i.e. the animation skeleton, and the animation model has a skeleton structure composed of interconnected animation skeletons, and the animation is generated for the model by changing the orientation and position of the bone skeleton.
CS skeleton, character Studio, is a very important insert for 3DS MAX, to simulate the actions of humans and bipedal animals.
Aligning the scaling bone with the CS bone, and scaling the scaling bone to be the same size as the CS bone and moving to the same location as the CS bone.
Fig. 8 is a flowchart of an animation model processing method according to another embodiment of the present application. As shown in fig. 8, when the second adjustment operation is a zoom operation, the above-described step S44 includes the steps of:
step S61, determining a scaling skeleton corresponding to the adjusting skeleton, binding the scaling skeleton with the animation model and inheriting the coordinates of the adjusting skeleton;
step S62, reversely obtaining a second scaling multiple of the scaling bone in the first coordinate axis direction according to the first scaling multiple of the scaling bone in the first coordinate axis direction, wherein the first coordinate axis direction comprises one coordinate axis direction or two coordinate axis directions of the scaling bone, and the scaling operation of the scaling bone in the first coordinate axis direction is opposite to the scaling operation of the scaling bone in the first coordinate axis direction;
step S63, obtaining auxiliary adjustment parameters of scaled bones according to the first coordinate axial direction and the second scaling multiple;
step S64, adjusting the scaling skeleton according to the auxiliary adjusting parameters.
Wherein the second scaling factor may be less than or equal to the first scaling factor.
For example, when it is desired to enlarge the length of bone a, the bone a is enlarged overall in the direction of the three axes X, Y, Z, the bone length is enlarged in the direction of the X axis, the bone thickness is enlarged in the direction of the Y, Z, and the overall magnification is the same in all three axes.
To achieve scaling of only the length of bone a, it is necessary to control scaling of bone a_adjust in the Y, Z axial direction by a scaling factor that may be slightly less than or equal to the overall scaling factor on the three axes in Y, Z axial direction.
Thus, by the zooming-in operation on the joint bone a and the zooming-out operation on the zoomed bone a_adjust, the bone a is elongated only in length and the bone thickness is not changed as a whole.
For another example, when it is desired to Adjust only the thickness of the bone B, only the change in the scaling bone b_adjust of the bone B in the Y, Z axis may be adjusted. For example, when scaling the thickness of the abdominal bone abdomens, its scaled bone abdomens_adjust may be adjusted only in the Y, Z axial direction. Thus, bone B is scaled only in thickness, with no change in length.
Through the embodiment, the single-axial or two-axial adjustment of bones can be realized, and the free change of the body of the animation model is realized.
