Design and Implementation of Virtual Museum Based on Unity3D

In order to improve the display effect and user immersion of the virtual museum, we constructed a virtual museum system based on Unity3D, and studied the high-precision 3D modeling, PBR material rendering, interaction optimization and performance enhancement strategies. The analysis shows that the system has better performance in visual reproduction, interaction fluency and concurrent access capability, but there is still room for optimization in complex lighting calculation and high concurrent load capacity. In the future, the system scalability can be further improved by combining intelligent navigation and cloud rendering technology.
