Embodiment Construction

[0022] The method for batch format conversion and weight reduction of 3D models proposed by the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that the file paths referred to in this patent are all paths that do not contain Chinese.

[0023] First, the software used in the method of the present invention is described. CATIA is the flagship product development solution of Dassault. As an important part of the PLM collaborative solution, it can help manufacturers design their future products and support the entire industrial design process from the pre-project stage, specific design, analysis, simulation, assembly to maintenance. The embodiment of the present invention is based on CATIA V5R19 version. 3DVIA Composer is a graphic software used for 3D product document publishing launched by Dassault of France, and 3DVIA Sync is its accompanying program. The embodiment of the present invention is based on the ...

Abstract

The invention relates to a three-dimensional model batch format conversion and lightweight method, which belongs to the field of computer simulation. The flow process of the method of the present invention is: use CATIA software to carry out batch conversion of stp format to three-dimensional solid model files; use the program 3DVIA Sync in 3DVIA Composer to carry out batch format conversion and lightweight processing to the obtained stp format model to obtain the 3ds format model; Unity3D imports the lightweight 3D solid model. The present invention comprehensively considers the model conversion effect, batch processing and input / output format requirements and other indicators, adopts suitable processing software, reasonable format conversion and lightweight processing methods, and effectively reduces the file size on the premise of ensuring the model display effect. Reduced model changeover time reduces costs.

Description

technical field [0001] The invention relates to a batch format conversion and lightweight method of a three-dimensional model, specifically relates to processes such as model export, model format conversion, and model reimport, and belongs to the field of computer simulation. Background technique [0002] At present, in the field of computer simulation, a crucial task is to perform format conversion and lightweight processing on 3D models in related computer-aided design software, and realize cross-platform multimedia objects such as 3D models through reasonable, practical and efficient processing methods run, and then integrate with the increasingly widely used mobile platforms. Among them, the advantages and disadvantages of 3D model format conversion and lightweight processing methods are particularly important, because the 3D model contains a lot of parameter information, and its file size is usually large, which puts forward high requirements for later model cross-platf...
