摘　　要：根据模型上各相邻三角面的法向,采用广度优先策略将模型划分。在划分中采用正向投影映射将各模型块参数化并对其进行评价,对于具有较大扭曲的模型块,将其再次细分直到扭曲值满足给定的阀值。对于各模型块的接缝采用Alpha-Blend技术将纹理拼接成一个连续的整体。该算法适用于任意曲面和多种纹理。This paper proposes a novel texture synthesis method to a wide variety of texture and any triangulated surface.According to the vector of the neighboring triangulated surfaces of model,it uses a extent first strategy to divide the model.The orthographic projection mapping has been used to parameterize and evaluate for each model block.When the model block has large tortuosity,it can fractionize the block until tortuosity value achieves the threshold value.For joint of each model block,it uses alpha-Blend technology to join textures into a consecutive whole.This arithmetic is available for all curve surfaces and all kinds of textures.
