Storing the group block modules into a group model library of the group block modules; specifically, in order to achieve the purposes of quick access and parallel loading of multiple blocks, for the rear end, after the large-scale geometric model is subjected to block processing, the same type of block modules are stored in a database, so that the number of the database can be reduced, a corresponding block module can be conveniently obtained, each block module is provided with a single storage path, and different block modules are provided with different storage paths, so that the purpose of parallel loading of multiple blocks at the front end can be achieved.
The front end obtains a plurality of block modules from one or a plurality of grouped model libraries in a multi-block parallel loading mode according to display requirements, specifically, when the front end displays a large-scale geometric model, the front end obtains corresponding block modules from different grouped model libraries according to the block modules formed by the large-scale geometric model, and loads each block module to the front end for display in the multi-block parallel loading mode.

Analyzing one or more block modules to obtain updated block modules; specifically, after loading all the block modules, part or all of the block modules need to be analyzed to obtain data information of the block modules, and because display parameters of the front end or hardware working parameters of equipment have different requirements on the data information of the corresponding block modules, the corresponding parameter information of the block modules need to be updated, and the block modules are matched with the display requirements of the front end by updating the parameters of the block modules, for example, the picture resolution of the block modules is 1024×768, and the resolution of the front end display is 1920×1080, then the display resolution of the block modules needs to be modified to adapt to the resolution of the front end display, and after the block modules are analyzed at this time, the updated block modules can be obtained by updating the set mode.
And updating the model view of the large-scale geometric model displayed at the front end according to the updated block module. Specifically, after the block module completes updating, the front end can display the model view of the large-scale geometric model according to the updated block module.
Particularly, for a large-scale geometric model, in order to simplify model data, the display performance of the large-scale geometric model carried out by the front end is improved, the rear end stores not only the complete data information of the large-scale geometric model, but also a plurality of corresponding light-weight model data with different precision after being simplified by a proper algorithm, the front end selects a light-weight model with proper precision according to the proper algorithm through the computer performance of a user, the complexity of the model, the distance of the model from a camera and the like, and the light-weight model data are only used for displaying the front end model.
In step 130, one or more block modules in the model view are edited at the front end according to the model view displayed at the front end, the edited block modules are saved to the back end, and the large-scale geometric model stored at the back end is updated.
Specifically, the model view displayed at the front end is formed by splicing a plurality of block modules, namely, the model view of the large-scale geometric model is divided into a plurality of independent units, so that when the large-scale geometric model is edited, the model view of the large-scale geometric model can be edited by editing one or more independent units, namely, the block modules, and after the editing is finished, the block modules to be edited are saved to the rear end in a parallel mode according to a plurality of blocks, and the block module data in the corresponding model library are automatically updated, so that the editing and updating of the large-scale geometric model are realized.
Specifically, in one embodiment of the present application, the editing, at the front end, one or more block modules in the model view according to the model view displayed at the front end, storing the edited block modules at the back end, and updating the large-scale geometric model stored at the back end, where the method includes:
acquiring one or more block modules edited at the front end;
acquiring data information of the block modules to be edited stored at the rear end according to the acquired one or more block modules edited at the front end; specifically, after the block module to be edited is determined, the data information of the block module to be edited stored at the back end is obtained, so that the parameter data of the block module to be edited is obtained.
Analyzing the data information according to the acquired data information of the to-be-edited block module, and editing parameters in the data information; specifically, editing the block module can be achieved by editing the data information of the block module, for example, for a rectangular block module, the data information parameters include: the length of the long side, the length of the short side, the thickness of the line, the color of the line and the like, and the specific display effect of the rectangular block module can be adjusted by editing the parameters.
Updating the front-end display effect of the large-scale geometric model according to the edited data information parameters; specifically, after the editing of the data information parameters of the block module is completed, the edited effect of the block module can be obtained through a front-end display mode, and the block module can be edited again or the editing of the block module can be confirmed to be completed according to the display effect.
According to the front-end display effect of the large-scale geometric model, adjusting data information parameters until the front-end display effect of the large-scale geometric model reaches a target effect;
storing the data information parameters of the edited block module, and transmitting the data information of the edited block module to the rear end in a multi-block parallel mode; specifically, for a plurality of block modules edited simultaneously, in order to improve the data transmission efficiency after editing, the data information of the block modules after editing is sent to the back end in a multi-block parallel mode, and the parameters of the block modules in the corresponding model library are updated by the back end.
Updating the large-scale geometric model stored in the back end.
Specifically, in a specific embodiment, the editing of the block module mainly includes the following types:
one is an operation of moving, rotating, copying, deleting, etc. the block modules, which performs one or more block modules to be edited as a whole.
The other type is to perform local editing on the block module, such as stretching a surface, performing boolean operations on the block module, and the like, and for this type of operation, requesting, through a network, the block module data with a partially complete model to be edited in the model library before performing editing. And then analyzing the data of the block module, updating the front-end display effect, and finally performing geometric editing.
After the local editing of the block module is completed, the edited block module is stored, the complete block module data information is released from the front end, the light-weight geometric model data of the block module of the modified part is requested again from the rear end, and the front end is updated.
The front end of the large-scale geometric model is edited, the original model view of the non-edited block module is kept by using the block module editing mode, so that very good editing performance is achieved, and meanwhile, the requirement of local detailed editing of the large-scale geometric model can be completely met.
After the large-scale geometric model is edited by the block module from the front end, the edited block module is required to be stored in a corresponding model library, new lightweight model data is generated at the rear end to replace an old lightweight model, and the success rate and the performance of storing the large-scale geometric model after editing are also important parts. The application discloses a method for carrying out block and increment preservation on a large-scale geometric model, which comprises the steps of firstly, carrying out block editing on the geometric large model, only preserving the edited block module part during preservation, preserving the edited block modules of a plurality of block modules, carrying out parallel data transmission on the edited block module data to the rear end for preservation according to a proper algorithm, thereby shortening the time for preserving the large-scale geometric model to be a fraction of the original time, and improving the success rate of preserving the large-scale geometric model after editing.
In step 140, external geometric model data is acquired, imported to the backend for format conversion and chunking.
Specifically, in order to support multiplexing of large-scale geometric models, the cost of user modeling is reduced. The method generally needs to support the importing of the external geometric model, is also suitable for a mode of parallel loading of a plurality of blocks when importing the external geometric model data, firstly carries out format conversion when the importing of the external geometric model data is acquired by the rear end so that the importing of the external geometric model data is suitable for the front end display requirement of the application, and then carries out blocking processing on the importing of the external geometric model so as to adapt to the requirement of parallel loading of the plurality of blocks by the front end.
In step 150, different display orders are set, the display of the model view displayed at the front end is simplified, the display orders are related to the material data of the model view displayed at the front end, and according to the different display orders, the large-scale geometric models with different display orders and the corresponding material data are stored at the rear end according to different paths.
In particular, the same-appearance model, a pure triangular patch model, uses less memory on the display and requires less time than an editable model. Therefore, the lightweight data are displayed in a manner of converting a common geometric model into a pure triangular surface patch, the model view displayed at the front end is displayed and simplified by setting different display orders, the display orders are related to the material data of the model view displayed at the front end, the block module data are simplified to a reasonable proportion by using a proper simplification algorithm, the simplified lightweight model data are stored in a database at the rear end, the file is uploaded to a remote file storage server, meanwhile, the material information and the path address of the file are stored in the database, when the front end requests the lightweight data, the rear end quickly returns the file path and the material information, and the front end automatically downloads the file according to the file path, so that the data dependence on the rear end service is reduced.
According to the stored complete large-scale geometric model data, the display magnitude can be set to be 5 types, and the display magnitude can be divided into: 1,0.8,0.6,0.4,0.2, 5 lightweight models with different precision are generated, the models with different precision are uploaded to file storage servers of different paths, and a plurality of model paths and material data used by the models are stored in a database. When the front end requests, a plurality of model paths and materials with different precision are returned to the front end, and the front end determines which model with different precision is adopted. Material data for different display orders: directly storing basic properties such as color, brightness, transparency and the like of the material; if the material has a map, the corresponding file path is stored in the material attribute.
Specifically, in one embodiment of the present application, the setting different display orders, and displaying the model view displayed on the front end is simplified, including:
