摘要:
In a method for determining weighting factors for the color calculation of a color value of texels for a footprint covering a plurality of texels in a texel grid, in a graphic system, form information of the footprint is determined at first. Afterwards, the edges of the footprint are determined and the edges determined in this way are approximated by a staircase function. The texels of the texel grid contacted by the staircase function are determined and a weighting factor is determined for each texel containing a portion of the staircase function, depending on the subarea of the respective texel covered by the footprint.

在图形系统中,在图形系统中,确定覆盖纹理纹格网格中的多个纹迹的覆盖层的纹理的颜色值的颜色计算的加权因子的方法中,首先确定印迹的形式信息。 之后,确定了足迹的边缘,以这种方式确定的边缘由阶梯函数近似。 确定由楼梯功能接触的纹理格子的纹理,并且根据由覆盖区域覆盖的相应纹理细分区域的子区域,确定包含阶梯函数的一部分的每个纹理像素的加权因子。
