纹理映射技术中Mip-Map的研究

在图形处理中,一个重要的研究方向是图形的真实感问题。纹理映射是高质量图像生成的一种重要技术,使三维图形更富真实感。Mip-Map纹理映射技术中,常常用一个正方形来近似表示象素在纹理空间的投影,但是像素投影并非正方形,是各向异性的,所以这种方法不符合反走样的要求,本文提出改进d值算法和长方形区域采样两种改进的算法来实现反走样。

Research on Mip-Map of Texture mapping

One of the most remarkable research direction in graphics processing is the actual sense.Texture mapping is a important technique in high quality image synthesis,the projection of the pixel on texture space is offen considered as a square in Mip-Map texture mapping,but projection of the pixel is anisotropic not a square,so this method is not accord with the request of antialiasing,so two method are presented for antialiasing,those are improve algorithm of d and footprint rectangle area sampling.
