摘要
给出了一种有效支持个性化变形的三维人脸模型结构和一种特征约束的实时连续多分辨率绘制方法。为方便变形中特征点及相关区域的移动,模型结构的设计体现了人脸特征及模型中点、边、面的邻接关系。基于这种模型结构的多分辨率绘制方法给出了特征约束的有序递减网格设计,实现了视距相关的快速模型简化,在保持模型视觉特征的同时保证了实时连续绘制。
Presentes a 3D human facial model structure for supporting the individual distortion and a real-time continuous multiresolution rendering method with feature-constraint. The model structure consideres the features and the adjacency of points, edges and triangles,and is convenient to the moving of featured regions in the distortion process. Based on it, the multiresolution rendering method presentes the design of feature-constraint sorted degressive mesh, establishes a quick simplifying of the model with view parameter, which can preserve the vision characters well and ensure the continuous real-time rendering.
