【摘要】 光线跟踪算法是一种高度真实感的图形绘制技术,由于其算法简单,容易实现而备受人们的重视。但同时光线跟踪算法是一种点采样算法,因而不可避免地产生图形走样,本文在实验的基础上,提出一种改进的基于光线跟踪的图形反走样算法,即像素细分技术和滤波技术向结合的算法,该算法反走样效果非常好,真实感强,并且性能好。更多还原

【Abstract】 Ray tracing is one of the best computer graphic techniques with high sense of reality.The advantages distinguishing itself are simple and easy to use,thus being valued by many experts in this field.At the same time,it’s an algorithm based on point sampling,and it will inevitably result in aliasing.Based on experiments,an improved anti-aliasing algorithm is put forward,that is,combined with pixel subdivision and filtering technology to overcome aliasing,and it has many strong points,such as high quality,high reality and better performance.更多还原
