| 摘 要： | 在真实感图形绘制中，纹理映射是表现物体表面纹理的一种非常重要的方法，在实际纹理映射时通常采用逆映射。本文提出的基于逆映射的利用像素裁剪纹理四边形的方法，可以精确地确定纹理四边形的平均纹理值，从而有效地克服了基于逆映射的纹理混淆现象。

| Abstract: | Texture mapping is a very important technique to produce the texture on the surface of an object in the computer synthesis of realistic images,Actually,the inverse mapping of the texture mapping is often adopted in practical applications. In this paper, a method based on the picture dlement clipping texture uradrilateral is prposed.Because this method can calculate precisdly the average value of texture in texture quadrilateral in texture inverse mapping,it successfully overcome the aliasing in texture mapping. |
