分析了一般的纹理映射反走样算法，提出了对纹理映射几何变换过程简化的改进区域求和表算法。算法通过对几何变换的局部线性化使得映射后象素多边形为平行四边形，然后在区域求和表法的基础上对矩形包围盒进行矩形自适应分割来完成反走样处理，实验表明改进算法在计算量增加了不大的基础上提出了图形质量。

The commonly anti aliasing algorithms in texture mapping are analyzed in this paper, and the modified summed area tables algorithms based on the simplification of the geometry transformation in the texture mapping are proposed. Through the local linearity of the transformation the mapped pixel become parallelogram, then the adaptive rectangle subdivision is proceeded on the bonding box to eliminate the aliasing. The result shows that the modified algorithm can improve the quality and reduce the calculation at one time.
