摘要
分析了Shear-Warp算法在实际绘制过程中出现的图像失真问题,提出了一种虚切片方法,通过在Shear-Warp算法基础上添加虚切片解决图像失真问题。实践表明,采用虚切片方法的Shear-Warp算法有效的解决了Shear-Warp算法的图像失真问题。
In this paper, we first analyze the image distortion of the Shear-Warp algorithm in practice, and then present a virtual slice method by increasing the important sampling points to solve the image distortion problem. Experiments show that the Shear-Warp method with virtual slices produces higher quality results.
