为更好地实现对三维模型局部细节的描写,提出一种中心扩散局部区域纹理映射方法。该方法以初始种子面为中心,采用广度优先搜索方法扩散确定待映射区域,保证待映射区域获得更好的圆度。在实现根据初始种子面的位置变化改变映射区域位置的同时,可始终保证纹理图像中心与纹理映射区域中心的对应,避免了纹理图像中心在纹理映射区域的中心偏移问题。实验结果表明了该方法的可行性。
To describe the local details of the 3D model,a method of center diffusion for local area texture mapping is proposed.The initial seed surface as the center,breadth-first-search method is used to determine the mapping area,to region a better roundness.It is accomplished that according to the location of the initial seed surface changes the mapping area,and the texture image center is corresponded to the texture mapping area center meanwhile,the problem that the texture image center offset the center of the mapping area is avoided.The feasibility of the method is proved by experiments.
