摘　　要：现代三维仿真系统中,大规模、精细模型的使用使得pc机难以进行实时渲染,因此该论文研究了一种模型简化算法,在同等分辨率条件下,最大程度的保留三维模型的外观特征。算法基于二次误差度量,引入了模型表面分类、顶点法向量偏移等约束条件。实验表明,该算法输出结果对模型外观保持程度较高。In modern three-dimensional simulation system, the using of large-scale, detailed model makes the pc machine difficult to achieve real-time rendering, so a model simplification algorithm was proposed, and under the same resolution conditions, the algorithm maintained the appearance of the 3D model realistic. This algorithm based on Quadric Error Metrics, used the model surface classification, vertex normal vector offset and other constraints to achieve the desired effect.
