摘要
目前纹理映射算法中不可避免地会出现纹理碎片,影响视觉效果。本文对碎片化纹理采取一种优化的方法进行研究。首先,将纹理映射结果中的碎片筛选出来;其次,提取碎片的内边界三角面;然后,提取纹理碎片的外边界三角面及其所选择的纹理影像;最后,用外边界面所选的最多的纹理影像替换碎片内部三角面所选的影像。实验表明,该方法迭代二次能够有效地去除纹理碎片。
In view of the inevitable texture fragmentation in the current texture mapping algorithm,this paper proposes an optimization method.First,the fragments in the texture mapping result are filtered out;second,the inner boundary triangle surface of the fragment is extracted;then the outer boundary triangle surface of the texture fragment and its selected texture image are extracted;and finally,the image selected by the inner boundary triangle surface of the fragment is replaced with the texture image mostly selected by the outer interface.Experiments show that the 2 iterations of the proposed method can effectively remove the texture fragments.
