Virtual reality (VR) technology is now very popular research topic , it involves graphics, artificial intelligence , sensor technology , and visual physiology and psychology , including related disciplines , and are widely used . One of the most critical technology of virtual reality technology is a real-time display of LOD ( Level of Details, LOD Model) technology . QEM (Quadric Error Metrics) is the the LOD techniques currently the most commonly used algorithm . Paper for triangular mesh simplification QEM algorithm simplified grid model local feature lost , based on the introduction of the QEM the new simplified algorithm , algorithms the curvature calculated optimize factor to improve the display quality of the simplified model , better simplified . Display speed , the paper also the dynamic LOD key technologies for progressive mesh and BSP ( BinarySpace Partitioning Tree) studied the progressive mesh algorithms into improved QEM simplification algorithm , combined with the BSP technology to display polygon control the number , the obtain more ideal display speed .
