Fig. 4 is a schematic diagram of an optional application scenario of the animation processing method provided by the embodiment of the present invention, in the application scenario, a terminal and a server cooperatively implement the animation processing method provided by the embodiment of the present invention, referring to fig. 4, a terminal device communicates with the server through a network, the network may include various connection types, for example, a wired communication link, a wireless communication link, or an optical fiber cable, etc., a bone animation editor is provided on the server side, the terminal sends an animation playing request to the server through the network, acquires an animation file set of an animation generated by the bone animation editor on the server side, and implements rendering of the animation based on the animation file set, so as to obtain and play the bone animation.
In another application scene, a skeleton animation editor is arranged at the terminal side, an animation file set of the animation is obtained through the skeleton animation editor arranged by the terminal side, rendering of the animation is achieved based on the animation file set, and skeleton animation playing is obtained and carried out.
Based on the application scenario of the animation processing method and the animation processing device, the implementation procedure of the animation processing method according to the embodiment of the invention will be described.
First, description will be made of an animation file mentioned in the embodiment of the present invention, in which an animation file is generated by an animation editor for realizing a specific type of file of an animation information record.
The animation file set acquired by the client at least comprises: an animation file of a skeletal model of an object, and an animation file (description file) of an action of the object;
the animation file of the skeleton model at least comprises a mapping file of a texture mapping of an object, a description file of skeleton information of the object and a description file of skin information of the object. In practical application, the description file mentioned in the embodiment of the present invention may be understood as a configuration file generated by an animation editor and describing animation information of an object.
Taking an animation editor as a Spine editor as an example, other animation editors, such as an open source engine DragonBones, can be used in practical application; the animation file may include: atlas file (description file), json file (description file), png file (map file); wherein, the atlas file and png file record all cut picture information before the drawing, and the json file records skeleton configuration and animation information, namely the most critical data of the Spine animation.
Next, the process of generating the animation file by using the animation editor as a Spine editor, which corresponds to generating the H5 skeleton animation, is described, and the corresponding Spine editor may select a multi-language runtime, optionally, a PIXI open source engine.
First, the working principle of the spin editor in the embodiment of the invention will be described.
FIG. 5 is a schematic diagram of the working principle of an animation editor according to an embodiment of the present invention, referring to FIG. 5, in an embodiment of the present invention, an object of a skeletal animation is composed of a skeleton, a slot, and an accessory; wherein, the skeleton and the slot are in a relation of 1 to N (positive integer greater than 1), and the slot and the accessory are also in a relation of 1 to N, which are respectively described below.
The skeleton structure of the object is tree-shaped, including root skeleton (trunk) and other skeletons (such as head-eye beads), the skeletons are connected together through a father-son relationship, the displacement (including rotation angle and position) of the skeletons is relative to the father skeleton, and the obvious advantage of the tree-shaped structure is that if the displacement is required to be set in animation, only the displacement of the root node is required to be set.
The slots can be inserted into the skin, which has transformation data (but not changes) in addition to describing which map to post (even a region on the map).
The accessory is used to show the external outline (look) of an object, and includes three types of information: pictures, skins and weight skins; the skin is used for indicating deformation characteristics of the picture, and comprises a vertex, an edge and a triangular area, and can deform a certain area of the picture, see fig. 6-1 and 6-2, and fig. 6-1 and 6-2 are respectively schematic diagrams of the picture before and after deformation by the skin according to the embodiment of the invention, and in fig. 6, a nose of a subject can be lengthened only by moving the vertex A to the right. The weight skin is used to indicate the weight of the bone on a vertex such that the position of the vertex varies with the bone.
The actions of the object in the skeleton animation are based on a time axis, the visual state of the object is updated along with time, a complete skeleton animation action can be decomposed on each skeleton, and each skeleton action is defined by a keyframe, a keyframe corresponding to the action of a certain time sequence point is used for describing skeleton characteristics of the action of the object at the time sequence point, that is, an action keyframe can indicate one or more actions of the object, for example, an action keyframe of running can correspond to the following actions: subject torso up and down, leg up and down, arm swing back and forth, elbow bending changes. One skeletal animation may correspond to at least two action key frames (a start action key frame corresponding to the start of an action and an end action key frame corresponding to the end of an action), and the state between two action key frames corresponding to two adjacent time series points may be obtained by interpolation. The time sequence points described herein may be understood as a sequence of time according to a time sequence or an action playing sequence, and are not necessarily real time (such as several points and several minutes).
In the embodiment of the invention, the animation editor generates a description file comprising at least two actions of the object through at least two action key frames set by a user, and the description file corresponds to the Spine editor and is a json file comprising at least two actions of the object.
When the animation editor performs skeleton animation editing, the generated original object is not decorated, so that blank (transparent) maps are needed to be taken up as space and packaged in the original page (David map), as shown in fig. 7, fig. 7 is a schematic diagram of an object map set with blank maps (blank maps are shown as reference numbers 1 and 2 in fig. 7), which are provided by the embodiment of the invention, obviously, more memory of a graphics processor (Graphics Processing Unit, GPU) is occupied when the blank maps are present, therefore, in the embodiment of the invention, the blank maps corresponding to the decoration are removed through a model deriving tool of the Spine, and canvas (canvas) with the same size as the blank maps is declared. Referring to fig. 8, fig. 8 is a schematic diagram of an object map setting provided in an embodiment of the present invention, in fig. 8, all blank areas in the dressing may be removed by removing x/y axis blank areas, each of the posted maps may be smaller in size than the actual size, blank areas on four sides of the map may be cut, the size of the dressing map may be changed to 1*1 (the actual picture may be restored by three values of orig, size and offset), and then the original size changed to 1*1 size is written into model data, so that the front end may generate canvas with the same size as the dressing picture according to the original size. One example code for removing the corresponding impersonation information of the corresponding blank map is as follows:
Fig. 9 is a schematic flow chart of the decoration drawing provided by the embodiment of the present invention, referring to fig. 9, in actual implementation, after the blank map is removed (in an embodiment, only the map of the skin type of the object is left), the size data of the removed blank map is written into the animation file of the object, so that after the front end parses the animation file, the canvas with the same size is declared, and then the decoration drawing of the object is performed. When the object is replaced, only the previous decoration is erased, and the latest decoration is drawn. Therefore, the memory occupation of the GPU is greatly reduced because of no blank mapping.
In the prior art, the Mipmap technology is started by default, namely the power number of 2 is limited by default, the Mipmap aims at texture map resources of an object, the Mipmap generates corresponding eight maps with different pixel sizes according to the difference of the distances of cameras, and obviously, the corresponding eight maps occupy a lot of memory space, in the bone animation of the embodiment of the invention, the change of the distance (size) of the object is not involved, therefore, the power number of 2 is not limited, and referring to fig. 8, so that when the animation is played by the front end, only the map files of the texture map corresponding to one specific pixel size are loaded in a memory, and the memory occupation of the map is greatly reduced.
In practical application, the description file generated by the animation editor often includes a plurality of actions of the object at different time sequence points besides skeleton information and skin information of the object, in the related art, the front end loads the description file including data information of the plurality of actions of the object in the process of playing the skeleton animation, that is, all action data of the object are loaded at one time, however, many actions of the object can only be used in a specific scene. Referring to fig. 10, fig. 10 is an exemplary diagram of the memory occupied by each action according to the embodiment of the present invention, and it can be seen that loading all the action data of the object into the memory at the same time greatly affects the playing smoothness of the animation.
In the embodiment of the present invention, a description file generated by an animation editor is split (by a terminal or a server), as shown in fig. 11, fig. 11 is a schematic diagram of splitting skeletal model data generated by the animation editor, and after splitting skeletal model data of an object, an animation file corresponding to each action of the object (each action corresponds to a time sequence point, and the time sequence points corresponding to two actions may be the same or different) and an animation file of a skeletal model of the object are obtained, so as to form an animation file set corresponding to skeletal model data; wherein the animation file of the skeletal model of the object comprises: skin information of the object, description file of skeleton information, and map file of texture map of the object. Because the motion data of the object is split, the front end can load only the model data of the object and two necessary motion data for the first time in the process of performing animation rendering, then load the data of each motion according to the requirement based on a time axis, re-integrate the motion data into the model data, and one method code example of integrating the split motion data into the model data is as follows:
The generation of the skeleton animation file and the split introduction of the skeleton animation file by the animation editor are already completed, and the playing process of the skeleton animation at the terminal side is explained next.
As an alternative embodiment of the above-mentioned animation processing method, fig. 12 shows an alternative flowchart of the animation processing method provided by the embodiment of the present invention, where the animation processing method of the embodiment of the present invention is applied to a terminal, and an animation processing client is provided on the terminal, referring to fig. 12, and the steps 200 to 205 are related to each other, and are described below.
Step 201: the client obtains a set of animation files in which animation information of the object is recorded.
Step 202: and loading the animation files in the animation file set in the memory of the client, wherein the loaded animation files correspond to the skeleton model of the object.
Here, the animation file corresponding to the skeletal model of the object is recorded with the information of the skeletal model.
Step 203: and loading the animation files in the animation file set in the memory sequence of the client based on the sequence of the time points, wherein the loaded animation files correspond to the actions of the object at different time sequence points.
And the animation file corresponding to the motion of the object at different time sequence points records the motion information of the object at different time sequence points.
Step 204: and analyzing the animation file loaded by the memory of the client to generate a rendering object comprising a skeleton model and actions of the object.
Step 205: and detecting that the rendering time of the rendering object of the corresponding action arrives, and performing animation rendering based on the generated rendering object to obtain the animation conforming to the action of the object at the target time sequence point.
As an alternative embodiment of the above-mentioned animation processing method, fig. 13 shows an alternative flowchart of the animation processing method provided by the embodiment of the present invention, where the animation processing method of the embodiment of the present invention is applied to a terminal, and an animation processing client is disposed on the terminal, and referring to fig. 13, the animation processing method provided by the embodiment of the present invention includes:
step 301: the terminal sends an animation playing request to the server.
In actual implementation, the animation playing request may carry information indicating the animation requested to be played, such as an identification or a name of the animation.
Step 302: and receiving the animation file set sent by the server.
Here, the animation file set is a set composed of a plurality of animation files obtained by splitting a skeletal animation file generated by an animation editor, and animation information of the object(s) is recorded. In this embodiment, the splitting of the skeletal animation file generated by the animation editor may be implemented by the server, or in other embodiments, the splitting of the file may be implemented by the terminal after obtaining the skeletal animation file returned by the server. It should be noted that, in some embodiments, when the motion data in the skeletal animation file is split, the motion data may be split based on time sequence points, that is, the obtained animation file of the corresponding motion may be one or more motion data corresponding to one time sequence point (it may be understood that the motion of the object corresponds to a plurality of time sequence points, each time sequence point corresponds to one key frame data, and each time sequence point may correspond to a plurality of fragment motions); in other embodiments, the motion is split based on different attribute features of the motion, and the obtained animation file of the corresponding motion may be motion data of one motion of the corresponding object.
In one embodiment, the animation file collection may comprise: an animation file corresponding to a skeletal model of the object and an animation file corresponding to an action of the object;
wherein the animation file corresponding to the action of the object includes: a plurality of description files of respective actions of the object at different time series points, in an embodiment, the animation file of the actions includes description files of actions corresponding to at least two time series points; wherein, the action data of the object at the same time sequence point forms a description file of an action, that is, the action of the object at the same time sequence point can be an action combination comprising a plurality of actions.
The animation file of the skeletal model of the corresponding object includes: a map file of a texture map of an object, a description file of skeleton information of the object, and a description file of skin information of the object.
Step 303: and loading the animation file of the skeleton model of the corresponding object in the animation file set in the memory of the client.
In practical application, after obtaining an animation file set of an object, a terminal determines an animation file of a skeleton model of the corresponding object in the animation file set and an animation file of an action of the corresponding object; firstly, loading a mapping file of a texture mapping of an object, a description file of skeleton information and a description file of skin information in a memory by a terminal side; in this way, under the condition that the description file of the action is not loaded, namely, only the mapping file of the texture mapping of the object, the description file of the skeleton information and the description file of the skin information are loaded, the loaded description file is analyzed to generate a rendering object, and then the animation rendering is carried out, so that a static model of the corresponding object can be obtained.
In some embodiments, the map files loaded in memory correspond to map files of texture maps of one particular pixel size, for replacing map files of texture maps of multiple pixel sizes of a default mechanism; for example, the animation editor side does not limit the power of 2, i.e. does not enable the Mipmap technology, so that the memory does not need to additionally load 7 texture maps with different pixel sizes, only the texture map with a specific pixel size meeting the actual requirement is loaded, and the memory occupation is greatly reduced.
Step 304: based on the sequence of time points, the description file of the action of the first time sequence point and the description file of the action of the second time sequence point are loaded in the memory of the client.
In actual implementation, the description files of the plurality of actions of the object correspond to a plurality of different time series points (in some embodiments, each time series point corresponds to a description file of an action, and each description file of an action records a plurality of fragment action data of the object), and the plurality of different time series points form a time series. In an embodiment, each action of the object (e.g. a fragment action set of an object corresponding to a certain time sequence point) may be played for a limited number of times, i.e. M times, where M is a positive integer, e.g. 10 times.
It should be noted that, in an embodiment, step 303 and step 304 may be executed simultaneously, i.e. the animation file of the skeletal model of the object and the description files of the actions of the first and second time series points of the object are loaded simultaneously, so that the terminal may obtain the animation of the object having the features corresponding to the two action description files when performing animation rendering.
Step 305: the loaded animation file is parsed to generate a rendered object that includes a skeletal model and actions of the object.
Here, in actual implementation, the generated rendering object including the skeletal model of the object includes: rendering objects corresponding to skeleton information, rendering objects corresponding to skin information and rendering objects corresponding to map information.
And analyzing the animation file loaded by the memory of the client to obtain the statement of the blank map for the decoration of the object, generating a blank canvas (canvas) with the size corresponding to the blank map based on the statement of the blank map, and drawing the decoration of the corresponding object on the blank canvas. Correspondingly, if the object is subjected to the reloading operation, the decoration of the corresponding object drawn on the blank canvas is removed, and the updated decoration of the object is drawn on the canvas after the drawn decoration is removed. After clicking the reloading, the user calls the reloading instruction of the user to reload the decorated description file corresponding to the instruction to realize the reloading of the decorated object S in the animation, and it should be noted that in some embodiments, the reloading of the object may not be completed based on the reloading instruction of the user, if the reloading is instructed in the animation file of the bone model of the loaded object at different time sequence points, then when the time arrives, the reloading operation is automatically executed, that is, the decorated object S on the canvas are removed and the reloading is carried out.
