在全景视图的实现过程中，关键技术是实现重叠图像正确、平滑的无缝拼接。

In the process of implementing panoramic image, on of the key techniques is to match the overlapping images correctly each other, making that the stitched image be seamless and smooth.

分离对象的物理视图与逻辑视图，隐藏物理视图的实现细节，使算法工作在高层的逻辑视图上，并通过视图变换将高层算法映射到低层中间表示上。

We separate the physical view and logic view of IR, and make algorithms work on the high-level logic view, and map the high-level algorithms into low-level IR through view transformations.

后一种情况可以通过提供其不同视图的呈现链接实现；请参阅 上文。

The latter case can be implemented with render links for its different views; see above.
