At the beginning, a generalization and introduction of image caching method are presented. Visual artifacts are kept under control by using an error metric that compares the angular discrepancy between the corners of the mapped quadrilateral and the referenced quadrilateral.
该文介绍了图像缓存算法的基本思想与相关研究,在实现方式中,计算参考四边形与映射四边形相对于视点的角度差,作为衡量缓存纹理是否可用的误差控制 标准,文章的最后提出了下一步有待于改进的研究点。
