本文提出了一种使用纹理样本对任意曲面进行纹理处理的方法，同时避免了变形、不连续和重复性。其原理在于用一系列局部参数化替换曲面的全局参数化，并报告内容的连续性约束。为此，我们制作了一组边界相容的三角形样本，我们在曲面上构建了一个由准等边三角形组成的网格，我们使用测地线将这些三角形投影到曲面上，并对每个三角形纹理块进行参数化。我们提出了在Perlin和Worley过程纹理的情况下合成具有连续性的纹理样本以及绘制或编辑图像的解决方案。
This paper presents a method for texturing any surface using texture samples while avoiding distortion, discontinuity and repetitiveness. The principle consists in replacing global parameterization of the surface by a serie of local parameterization, and reporting the continuity constraints to the content. For doing this, we make a set of triangular samples whose borders are compatible, we build a mesh of quasi-equilateral triangles on the surface, we project these triangles on the surface using geodesics, and we parameterize each triangular texture patch. We propose solutions to synthesize textures samples having the continuity property in the case of Perlin and Worley procedural textures, and to draw or edit images.
