基于中介媒介的交互式纹理映射

Interactive texture mapping based on mediation media

目前,绝大多数的纹理映射方法是将纹理图案映射到物体模型的整个表面,而局部纹理映射的方法却少之又少。然而在实际的应用中,物体模型需要映射的区域可能只是局部。根据这一问题,提出一种基于数据拓扑结构的交互式纹理映射方法,即通过拾取点建立待映射区域的拓扑结构,然后选择合适的中介媒介实现纹理映射。实验结果表明此方法既可以实现规则模型的局部纹理映射,也可以实现不规则的三维重建模型的局部纹理映射,并可以通过鼠标在模型表面选点后在选择区域上实现交互式局部纹理映射,且都取得良好的映射效果。

Nowadays,the vast majority of texture mapping method is to map the texture pattern to the entire surface of the object model,and the local texture mapping method is rare.But in the practical application,the areas need to be mapped may only be local.According to this situation,we put forward a kind of interactive texture mapping method based on topology data.The topology of mapping area is established through the pick-up points then texture mapping is realized by selecting appropriate intermediary media in this method.Experiments show that this method can not only realize the local texture mapping of regular model,but also the local texture mapping of irregular three-dimensional reconstruction model,and can realize interactive local texture mapping on the selection area after selecting the points on the model surface with the mouse,and the mapping effect is good.
