基于三角块的曲面纹理合成

Triangular-Patch Based Texture Synthesis on Surfaces

  • 摘要: 根据曲面网格上的切向矢量场,采用广度优先搜索策略从样本纹理空间中为每个三角面片映射纹理面片,直至完全覆盖整个网格在搜索和映射过程中,首先使网格上相邻三角面片的纹理有最小的匹配误差;然后对相邻的三角面片纹理使用图的分割方法拼接纹理,得到曲面上连续的合成纹理;最后压缩存储合成的三角面片纹理该算法适用于多种类型的样本纹理和任意的三角化曲面.

     

    Abstract: We propose a novel texture synthesis method to a wide variety of textures and any triangulated surfaces. Our idea is to progressively map triangles of mesh to the texture space until the surface is completely mapped. First, we create a tangential vector field over the mesh. Then, the mapping process searches the most optimal texture patch for each triangle in texture sample. For synthesizing continuous texture, we compute the best triangle patch seam between the parts of textures of neighboring triangles by using a graph cut technique. Finally, the texture coordinates are generated and the synthesized texture is compressed to an atlas.
