The embodiment of the application provides a method for generating a skin animation LOD model. Referring to fig. 2, fig. 2 is a flowchart illustrating a method for generating a skin animation LOD model according to an embodiment of the present application. The generating method may include the steps of:
s210, acquiring grid data and a face reduction rate of an original skin animation model; wherein the mesh data includes vertex data and triangular patch data.
In the embodiment of the application, the original skin animation model is a grid model with highest fineness, and is taken as LOD 0 Vertex data and triangular patch data of the mesh model are read, and a face reduction rate is determined. The face reduction rate is used for representing an evaluation index which enables the model to be simplified most under the condition that the minimum characteristic change of the model before and after simplification is ensured as much as possible. That is, the reduction ratio is a preset degree of the model to be reduced, and the value may be a range from 0 to 1.
S220, carrying out face reduction treatment on the original skin animation model according to the face reduction rate to obtain a plurality of grades of lightweight models; and deleting all vertex data in the lightweight model of each level in the face reduction processing process.
In the embodiment of the application, the original skin animation model is subjected to the face reduction treatment according to the face reduction rate from large to small, so that a plurality of grades of light models with fine degree (data size) arranged from high to low can be obtained and respectively used as LOD (line of sight) 1 -LOD N Wherein N is a positive integer greater than 1. It will be appreciated that the lightweight model contains less vertex data and less triangle patch data. In order to further reduce the data amount, in the face-reduction processing, a vertex deletion method is adopted, and since vertex data can be multiplexed, all vertex data in the lightweight model of each level can be deleted. That is, LOD 0 Store all vertex data and triangular patch data, while LOD 1 -LOD N Only the triangular patch data after the face subtraction processing is stored.
S230, generating a skin animation LOD model according to the original skin animation model and the light weight models of a plurality of grades.
In the embodiment of the application, an original skin animation model is taken as LOD 0 The lightweight models of a plurality of grades are respectively used as LOD 1 -LOD N Since vertex data is deleted from each level of lightweight model, only triangular patch data is stored, and the overall data volume can be reduced.
For example, if the original skinned animation model LOD 0 Vertex number V of mesh of (2) 0 24744 number of triangular patches F 0 49108. LOD is realized by adopting the traditional light weight technology 0 Simplifying, and taking a lightweight model with 80% of the surface reduction rate as LOD 1 The number of vertexes of the grid V 1 19834 number of triangular patches F 1 39288; a light model with a reduction of 50% was used as LOD 2 The number of vertexes of the grid V 2 12468 number of triangular patches F 2 24556; a light model with a reduction of 10% was used as LOD 3 The number of vertexes of the grid V 3 5101 number of triangular patches F 3 9822. The number of vertices required to be stored for the generated skinned animated LOD model is 62151 and the number of triangular patches required to be stored is 122274. If the vertex coordinates are represented by double-precision floating point numbers and the vertex indexes of the triangular patches are represented by integer numbers, the mesh data amount required to be stored by the skin animation LOD model is as follows:
62151*3*8+122274*3*4＝2958912B.
in the embodiment of the application, the light weight of the skin animation model adopts a vertex deleting mode, and vertex data can be multiplexed. I.e. LOD 0 Store all vertex data and triangular patch data, while LOD 1 -LOD N Only the triangular patch data after the face subtraction processing is stored. The number of vertices V' that the generated skinned animated LOD model needs to store is:
V′＝V 0 .
at this time, the mesh data amount that the skin animation LOD model needs to store is:
24744*3*8+122274*3*4＝2061144B.
therefore, by adopting the method for generating the skin animation LOD model, the grid number can be reduced by more than 30%.
As can be seen from the foregoing, in the generating method of the skin animation LOD model provided by the embodiment of the present application, by acquiring the mesh data and the face reduction rate of the original skin animation model, where the mesh data includes the vertex data and the triangular patch data, the face reduction processing is performed on the original skin animation model according to the face reduction rate to obtain a plurality of grades of lightweight models, where all the vertex data in each grade of lightweight models are deleted during the face reduction processing, and the skin animation LOD model is generated according to the original skin animation model and the plurality of grades of lightweight models, and since the vertex data is deleted in each grade of lightweight models and only the triangular patch data is stored when the skin animation LOD model is generated, the overall data amount can be reduced.
Optionally, in the foregoing embodiment, before step S210, the generating method further includes:
performing at least one of the following preprocessing operations on the original skinned animation model:
deleting repeated vertexes of the original skin animation model;
repairing the joint of the original skin animation model;
and removing the overlapped part model in the original skin animation model.
In the embodiment of the application, the repeated vertexes of the original skin animation model are deleted, the joints of the original skin animation model are repaired, and the overlapped partial models in the original skin animation model are removed, so that the original skin animation model is internally fused into a whole under the condition of keeping the appearance structure unchanged, and compared with the original skin animation model, the whole is on basic data, and a large amount of repeated vertexes, lines and overlapping entity data are reduced. Therefore, the data structure of the original skin animation model is greatly optimized, the data volume is reduced, and the difficulty in simplifying the original skin animation model in the later period is reduced.
In specific implementation, the facet reducing rate is preconfigured according to at least one requirement of different platforms, different hardware, different terminals and different application scenes.
Wherein the different platform may be at least one of an artificial intelligence adaptive platform, a three-dimensional modeling platform, a platform for texture rendering, and the like. Correspondingly, different hardware, different terminals and requirements for matching different application scenes can be deployed on different platforms according to requirements.
Further, in the above embodiment, in step S220, the face reduction process is performed on the original skin animation model according to the face reduction rate, so as to obtain a plurality of grades of lightweight models, including:
and carrying out surface reduction treatment on the original skin animation model in a vertex deleting mode according to the surface reduction rate to obtain a plurality of grades of lightweight models.
In the embodiment of the application, in the face reduction processing process of the original skin animation model, the original skin animation model is simplified by adopting a vertex deleting mode, and meanwhile, vertex data can be multiplexed by adopting the vertex deleting mode, so that the simplified lightweight model only contains fewer triangle patch data, and the whole data quantity is greatly reduced.
Optionally, in the foregoing embodiment, the generating method further includes:
and converting the skin animation LOD model into a target model file according to the target file format.
In the embodiment of the application, the generated skin animation LOD model is converted into the target model file according to the target file format required to be output. Meanwhile, a visual rendering environment can be built, and the target model file is loaded into the visual environment to perform skin animation LOD model rendering visualization.
