基于Mip-map的纹理映射反走样技术

Anti-aliasing Technology of Texture Mapping

计算机图形最终成像的质量和许多因素有关。图像假象问题是由于建模和其他因素引起的,它们是生成图像所用的渲染算法运算的结果。渲染用时越少,质量越高,渲染出来的图像就越逼真。利用纹理映射技术则可以使渲染达到令人满意的效果。但是现有的纹理映射技术有其相应的局限性,不能满足实时的需求。在利用OpenGL图形库的基础上,基于改进的Mip-map纹理映射技术能有效的解决上述问题,并且给出了改进前后图像清晰度的对比,以及时间上的对比。

The computer-generated image quality involes many factors.Image illusion problem is caused by modeling and other factors,and is the result of rendering algorithm operation in generating images.Less the rendering,higher the quality,and the more realistic rendering pictures.By using the texture mapping technology,rendering could achieve satisfactory results.However,the existing texture mapping technique has its corresponding limitations and could not meet the real-time requirement.With OpenGL graphics library,the improved Mip-map texture mapping technology could effectively solve these problems.In addition,this paper gives the contrast of image definition before and after improvement,including the contrast of time.
