Abstract: This paper proposes a novel method for surfaces texture synthesis based on elements distribution construction, in order to preserve the underlying regularity of texture samples in the synthesized texture over surfaces. This paper firstly specifies an initial position on the 3D surface by user interaction, and then expands it outward by using local growth based on neighborhood comparisons under collision detection, in order to construct the distribution of texture elements over 3D surfaces, which maintains a certain visual resemblance with the input 2D reference connectivity. According to the positions information provided by the constructed distribution of texture elements, this paper obtains the final synthesized result by pasting the extracted texture elements onto the 3D surfaces. The    experimental results show that the proposed method can produce high quality textures over surfaces, which not only preserve the texture elements integrity and the underlying structural regularity well, but also guarantee low distortions and no cracks in the synthesized results.
