基于Wang Tiles的几何纹理合成

提出了一种基于Wang Tiles的几何纹理合成方法来在不同物体表面上即时地生成几何纹理.首先根据给定的几何纹理预计算出一组Wang Tiles,然后用这组Wang Tiles在不同的目标物体上即时生成新的几何纹理.尽管基于Wang Tiles的方法已经应用于图像纹理,但由于几何纹理采用了与图像纹理完全不同的表示方式,因此需要用完全不同的方法来处理.采用了基于约束的几何纹理合成技术自动生成几何纹理Wang Tiles,从而保证了生成的几何纹理Wang Tiles在所有排列下都能保持其几何连续性.与现有的方法相比,生成的几何纹理Wang Tiles可以重用到不同的目标物体上,同时占用的存储空间及计算量更小,速度更快.

Wang Tile Based Geometric Texture Synthesis

This paper presents geometric texture Wang Tiles to generate geometric textures on different object surfaces at run-time. A set of Wang Tiles is pre-computed from a specific geometric texture and used to generate geometric textures on different object surfaces. Although tile-based approaches are used for image textures, constructing geometric texture Wang Tiles presents additional challenges due to the differences between geometric textures and image textures. The geometric texture Wang Tiles is built automatically by using constrained synthesis to ensure geometric continuity across all possible combinations of tile arrangements. Once a tile set is built, it can be reused for texturing different output objects. This texturing algorithm consumes much less storage and computation than the existing methods.
