基于场景图的图像缓存绘制加速技术的方法
A Method of Accelerating the Rendering of Scene Graph Based on the Image Caching
【摘要】 介绍了一种基于图像缓存技术的绘制加速方法,该方法利用漫游静态场景中视点移动的连续性加速绘制过程。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。
【Abstract】 This paper presents a method of accelerating the walkthroughs of geometrically complex scenes utilizing the path coherence. 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.
