摘要： MIPmap是当前各种硬件图形加速卡普遍支持的一种纹理映射方法，但它存在着过模糊和明显的走样现象。该文提出基于MIPmaps纹理数据结构的纹理映射算法，改进了纹理细节层次的计算方法，在存储带宽受限制的条件下尽量多存取纹理元素，并对存取的纹理采用高斯加权，从而改善了绘制图像的质量。

Abstract: In current graphics acceleration hardware, MIPmap is a common used filtering technique. But it exists blurring and aliasing artifacts. This paper describes a texture mapping technique, which is based on MIPmaps. With the restricted number of texels loaded from memory for real-time filtering, it improves the algorithms of LOD, and filters the texels with Gaussian filter. As the result, the visual quality is improved.

Key words: MIPmap method, texture, aliasing, Gaussian filtering
