对相邻的已合成三角形个数为1的待合成三角形使用“纹理延伸”的方法进行纹理合成;对相邻的已合成三角形个数大于1的待合成三角形采用梯形模板匹配的三角块拼接方法进行纹理合成.实验结果与理论分析表明,该算法合成质量较高,合成速度较现有方法提高了1/3.
We present a fast algorithm of texture synthesis on arbitrary surface using "texture extension" and optimal texture coordinates searching. As to those triangles where there is only 1 neighbor triangle synthesized, we get their texture coordinates by directly extending the neighbor triangles' texture coordinates, while those triangles with 2 or 3 synthesized neighbors are synthesized by searching their texture coordinates according to their trapeziform show that synthesis time of our algorithm is about borders. Some experimental results are presented which 2/3 of that of previous methods.
