Design and Implementation of Virtual Interactive Scene Based on Unity 3D

This paper demonstrates three-dimensional modeling method of virtual reality, and presents a 3D interactive virtual scene design based on the Unity 3D technology, combined with AutoCAD, MultiGen Creator and Unity 3D software platform. In this process, the scene and different format file has been optimized, the network interactive viewing of virtual scene is realized too. It focuses on an example designed to obtain a better real-time, interactive and good visual effects.
