Abstract

Abstract:

The research and development of aero-engines has the characteristics of high precision and interdiscipline. In order to reduce communication costs and to display the engine structure and the state of semi-physical simulator, by applying virtual reality technology, an immersive scene simulation system is built. By studying CAD data lightweight technology and physics-based real-time rendering technology, a rendering optimization method for similar object dynamic batching is proposed, which effectively improves the rendering frame rate. A dynamic parallax adjustment algorithm is proposed to solve the problem of dizziness when having a close look to stereoscopic images. The system achieves the strong immersion, high fluency, and high precision visual effects. The relevant technology can be applied to the engine immersive review, virtual training and other scenarios, and can provide technical support and reference for the application of virtual reality technology in manufacturing field.

Key words: virtual reality, scene simulation, virtual assembly, Unity, digital twin, stereo imaging
