摘要 提出了一种动态实时的进行纹理映射的方法,该方法首先通过自动寻找三维旋转模型主中轴线来与纹理图片的中垂线进行配准,然后沿左右方向进行纹理保长等单位映射。该方法可将纹理图片等单位的映射到三维模型上,同时可以进行模型修正和纹理图片的动态移动,纹理不会变形,这完全不同于其它指定多边形及相应纹理坐标进行插值的纹理映射方法,后者将无法与用户进行交互且无法动态贴图。实现结果表明,该方法很好地模拟了现实世界的贴图效果,且具有很好的灵活性、实用性和通用性,可以应用到陶瓷贴花的虚拟现实软件中,进行提前演示效果。 A method of dynamic and real-time texture-mapping is proposed, which first searches the axle wires of the 3d rotation-model and the texture picture automatically, and matches them. And then texture mapping of equilong and equal-unit is carried out through left and right. This method can map the texture picture on the 3D model commensurately, and supply revision of model and dynamically moving of texture picture that have been mapped on the model, accompanying with no deformation of texture. This is not the same ab- solutely as other methods that appoint the coordinates of polygon and texture and interpolate on the inner region, the latter cannot alternate and move picture optionally. The result proves that this method simulates the real-world effect of mapping perfectly, and flexibility, practicability and commonality are showed. This method can be used in the virtual-reality system of texture mapping of crockery and china, demoing the effect previously.
