AI Technical Summary

Technical Problem

In the existing technology, VR simulation systems lack effective tools to convert material attribute information in model files, such as lighting, reflection, material, and texture, in civil aircraft design simulation evaluation, resulting in excessively long manual adjustment time.

Method used

By parsing common CAD model files, a data structure is constructed to organize model data, material information is extracted and converted synchronously, and directly applied in VR visualization models. The file format is parsed using Quazip and QtXml libraries, and texture information is extracted using VRML technology. A tree node structure is established for model fusion.

Benefits of technology

This technology enables the simultaneous extraction and conversion of material information while converting the geometric properties of the model, thereby improving the efficiency of model conversion and ensuring the quality and integrity of the conversion.

Abstract

This application relates to the field of virtual reality technology, and more particularly to a CAD digital model VR visualization method, computer device, and storage medium. The CAD digital model VR visualization method provided in this application, by parsing the open file format of the CAD digital model, simultaneously extracts the model's material information and directly converts it into the VR visualization model while converting the model's geometric property format. It ensures the integrity and accuracy of the model's assembly tree information, outputting a universal 3D model file or a custom file format, enabling rendering software to seamlessly read it and ultimately display it in the VR system. This ensures richer model information during conversion and effectively improves model conversion efficiency. The computer device provided in this application can implement the steps of the above-described CAD digital model VR visualization method, and therefore also possesses the aforementioned technical effects. The computer-readable storage medium provided in this application can implement the steps of the above-described CAD digital model VR visualization method, and therefore also possesses the aforementioned technical effects.
