Description
Technical Field
The present invention relates to the field of three-dimensional model processing, and in particular, to a three-dimensional model file processing method, device, storage medium and server.
Background
Computer graphic image technology has been widely used in the fields of game entertainment, industrial manufacturing auxiliary design, indoor and outdoor building design, etc.
Thanks to the development of graphic image technology, AR/VR technology has also developed rapidly in recent years, and its biggest feature is to bring realistic real-time picture effects and interactive experience to users. Thus, the "realistic real-time visual effects" and "interactive experiences" are key goals that must be achieved in the AR/VR content production process.
The operation process of the AR/VR content mainly comprises the following three steps: firstly, reading three-dimensional model file data into a memory, then performing rendering calculation through a GPU, obtaining pixel picture effects of a single frame after finishing calculation, and finally transmitting the picture effects to a user interface for display for a user. This process must be repeated more than 30-40 times per second to ensure that the user is able to get a comfortable and smooth experience.
Because the computational power of the hardware is limited by cost (a cost of purchase acceptable to a typical consumer), more stringent requirements are imposed on the production of AR/VR content to achieve the above requirements. The more triangles a three-dimensional model to be presented on a screen contains, the longer the calculation time is needed, and conversely, the less the calculation time is needed. The more triangles a three-dimensional model contains, the higher the fidelity of the picture, and vice versa. Therefore, the main contradiction is that the realistic effect of the rendered picture is ensured, and the rendering speed of 30-40 frames is kept under the hardware environment with limited computing power.
To solve the contradiction, the common practice in the industry is to optimize the three-dimensional model to be displayed by a 3D art designer, and control the total number of triangular faces contained in the three-dimensional model in a reasonable range. On one hand, the most abundant model details are represented by the least triangular faces as possible, and on the other hand, unnecessary triangular faces are reduced as much as possible, so that the calculation time is reduced, and the experience requirement of a user is met.
However, the optimization process includes multiple processes of building a high-precision model, subtracting a surface, developing UV, baking a normal map and the like, and depends on a designer to operate through various image processing software, and the time is different from a few hours to a few days, so that labor and time are very consumed.
Aiming at the problems of complex process, long time consumption and high labor cost caused by adopting image processing software to optimally process a three-dimensional model file in the related technology, no effective solution is proposed at present.

According to an embodiment of the present invention, preferably,
the receiving of the three-dimensional model optimization parameters and the three-dimensional model files configured by the user at the terminal comprises the following steps:
receiving a face reduction ratio or polygon total face number parameter set by a user at a terminal, and receiving a three-dimensional model file selected by the user at the terminal;

and when the three-dimensional model optimization parameters meet preset conditions, performing face reduction calculation operation on the three-dimensional model file according to face reduction proportion or polygon total face number parameters.
Because the 3D model input by the user comprises tens of millions and hundreds of millions of triangular surfaces, the use condition of the consumer-level application scene cannot be met, and the surface reduction optimization processing is required.
The intelligent face-subtracting algorithm in the embodiment carries out reconstruction calculation based on the morphological boundary of the input model, combines adjacent vertexes and faces, and constructs a new triangular face structure similar to the original morphology. For example, two line segments containing three vertices are combined into one line segment and two vertices. The two triangular faces contain six vertices and are combined into three vertices of a triangular face. Generating a new triangular surface will approximately preserve the coordinate orientation and boundary size of the original shape.
According to an embodiment of the present invention, preferably,

receiving a spreading UV mode parameter set by a user at a terminal, and receiving a three-dimensional model file selected by the user at the terminal;
when the three-dimensional model optimization parameters meet preset conditions, optimizing the three-dimensional model file according to the three-dimensional model optimization parameters comprises:
and when the three-dimensional model optimization parameters meet preset conditions, performing unfolding UV mapping calculation operation on the three-dimensional model file according to the unfolding UV mode parameters.
The surface texture of the 3D model file contains picture information such as diffuse reflection mapping, highlight mapping, AO mapping, normal mapping, and the like. These pieces of picture information data are stored based on a two-dimensional coordinate system (indicated by U, V). The three-dimensional structure of the 3D model includes information data such as vertices, line segments, triangular surfaces, and the like, which are stored based on a three-dimensional coordinate system (indicated by X, Y, Z).
In the intelligent UV display in this embodiment, after the 3D model is reconstructed, the mapping relationship between the newly generated stereo structure and the texture map can be recalculated. This ensures that the texture map contained in the model before the non-optimization can be used on the newly generated model.
According to an embodiment of the present invention, preferably,
the receiving of the three-dimensional model optimization parameters and the three-dimensional model files configured by the user at the terminal comprises the following steps:
receiving a chord height tolerance value and a chord angle tolerance value parameter set by a user at a terminal, and receiving a three-dimensional model file selected by the user at the terminal;

The user imports (uploads from the client to the cloud) the CAD model data, and optimally converts the CAD model data into a 3D model based on vertexes, lines and trigonometry surfaces. Since CAD model data is actually an abstract set of functions, it does not contain specific numerical results. When the accuracy difference exists in the conversion, the higher the accuracy of the parameter input by the user is, the closer the converted triangular surface grid is to the shape of the function curve, and otherwise, the lower the accuracy is, the simpler the converted triangular surface grid shape is. In popular terms, the difference perceived by the naked eyes of a user is that the smoother the surface of the 3D model with higher precision is, the more true the details are, whereas the 3D model with lower precision is, the rougher the surface is, the less and the unreal the details are.
Aiming at the first type of CAD model data, in the embodiment, the intelligent optimization CAD algorithm is adopted to calculate the topological structure of the curved surface data, a plurality of triangular surfaces are created, the overlapped vertexes and boundaries are combined with each other, and then a new three-dimensional grid structure is formed. The purpose of this is to convert the surface data type into a triangle surface data type, i.e. to change it into a second type of data.
In a specific embodiment, the accuracy parameters may be preset, and then the "intelligent optimization CAD algorithm" is used to convert the CAD model data that is imported (uploaded from the user terminal to the cloud) into triangular model data, so as to obtain a 3D model file that can be smoothly operated in the corresponding terminal device.
According to an embodiment of the present invention, preferably,
the receiving of the three-dimensional model optimization parameters and the three-dimensional model files configured by the user at the terminal comprises the following steps:

and performing baking normal map calculation operation on the three-dimensional model file according to baking parameters.
The AR/VR content will typically include a wide variety of 3D models such as personas, clothing, props, mechanical structures, architectural shapes, etc. The appearance of these models varies and the object surface contains various texture details such as leather texture, cloth fabric, metal scratches, metal rust, wood grain cracks, etc. The higher the degree of restoration of these details in the picture, the more realistic the user can get a more realistic substitution experience. It is therefore critical for the user experience to preserve as much as possible the texture details of the object surfaces.
In a specific embodiment, the above-mentioned process is an intelligent PBR algorithm, and three-dimensional texture data can be stored in the process by analyzing the texture detail structure of the 3D model surface and then mapping the texture detail structure to a picture, and using three channels of RGB. This picture (Texture) is called Normal Map. All detail data of the high-precision model is reserved and stored in a corresponding normal map. Based on the face reduction proportion or the polygon total face number parameter, the unfolding UV mode parameter and the baking parameter combined with the intelligent PBR algorithm, the optimization processing of the three-dimensional model file is realized, the processing process is greatly simplified, the processing time is shortened, and the labor cost is reduced.
