Abstract

A volume-reduction optimization method for three-dimensional solid model is based on three types of software including CATIA, three-dimensional engine Virtools and 3DMAX, employs CATIA to save a related CAD model in a specified format, then imports a related solid model into Virtools so as to carry out optimization operation on the solid model by use of Virtools and save the model by use of Virtools, and finally imports the solid model into 3DMAX to complete operations, such as material processing, texturing and baking, on the three-dimensional solid model. The method specifically comprises saving the three-dimensional solid model file in the specified format by use of the CATIA software; opening the three-dimensional solid model file by use of the Virtools platform; performing volume reduction processing on the three-dimensional solid model file by use of the Virtools platform; exporting the three-dimensional solid model; and importing the volume-reduced three-dimensional solid model by use of the 3DMAX software.

Description

【Technical field】 [0001] The invention relates to a lightweight optimization method for a three-dimensional solid model, specifically relating to processes such as model export, model format conversion, optimization operation, and model reimport, and belongs to the field of aerospace simulation. 【Background technique】 [0002] At present, in the field of aerospace simulation, an important task is to import the 3D solid model from relevant computer-aided design CAD software (such as product development solution CATIA software) to simulation graphics processing software (such as 3D animation software 3DMAX, etc.) for processing . However, since the 3D solid model contains a lot of parameter information, its file size is usually very large, which puts forward high requirements for the later graphics processing equipment, and also reduces the efficiency of graphics processing and increases difficulties. It does not meet the needs of the current technological development and nee...
