Problems solved by technology

[0002] Currently, there are 3D model formats on the market, including binary and text formats, and some with all data embedded. However, each 3D model format does not have many essential features except for the amount of data stored and the type of data. the difference
Especially for the model loading and display process in the case of network transmission, there is not much difference and optimization
[0003] However, all existing 3D model loading processing methods do not consider how to display faster in the case of network transmission, and do not consider how to reduce memory peaks during loading
The existing 3D model format basically does not support multi-threaded simultaneous loading and analysis of the same 3D model, which greatly limits the loading and analysis speed of a single 3D model

Abstract

The invention provides a method and device for processing 3D model data. The 3D model data comprises multiple data types. The method comprises the following steps: dividing 3D model data of different data types into one or more sub-files, wherein the sub-files comprise file identifiers, and the file identifiers of the sub-files of the same data type are associated; loading and analyzing multiple sub-files in a multi-thread mode; and combining the data analyzed by each thread according to the analyzed file identifier so as to complete processing of the 3D model data. By using the method provided by the invention, the 3D model can be loaded, analyzed and displayed in a segmented manner in a multi-thread manner, and the loading waiting time of the 3D model in network transmission can be shortened.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method for processing 3D model data. Background technique [0002] The 3D model formats currently on the market include binary and text formats, and some with embedded data. However, each 3D model format does not have many essential features except for the amount of data stored and the type of data. the difference. Especially for the model loading and display process in the case of network transmission, there is not much difference and optimization. [0003] However, all existing 3D model loading processing methods do not consider how to display faster in the case of network transmission, and do not consider how to reduce memory peaks during the loading process. The existing 3D model format basically does not support the simultaneous loading and analysis of the same 3D model by multiple threads, which greatly limits the loading and analysis speed of a single 3D mo...
