摘要:
A method for generating a presentation of a region-of-interest in an information representation including the steps of: selecting a viewpoint for the region-of-interest; creating a lens surface for the region-of-interest; the lens surface having a focal region and a shoulder region surrounding the focal region; creating a transformed presentation by: determining boundaries in the representation for the focal region and the shoulder region; determining boundaries on the lens surface corresponding to the boundaries in the representation by applying a distortion function defining the lens surface to the boundaries in the representation; perspectively projecting the boundaries on the lens surface onto a plane spaced from the viewpoint; and, copying information in the representation lying within the boundaries in the representation onto the focal region and the shoulder region of the lens surface using respective focal region and shoulder region stretch bit-block transfer operations; and, displaying the transformed presentation on a display screen to generate the presentation of the region-of-interest.
摘要(中):
一种用于生成信息表示中的感兴趣区域的呈现的方法,包括以下步骤:选择感兴趣区域的视点; 为感兴趣区域创建透镜表面; 所述透镜表面具有聚焦区域和围绕所述聚焦区域的肩部区域; 通过以下方式创建变换的演示:确定焦点区域和肩部区域的表示中的边界; 通过将限定透镜表面的畸变函数应用于表示中的边界来确定与代表中的边界相对应的透镜表面上的边界; 透视地将透镜表面上的边界投影到与视点隔开的平面上; 以及使用各自的聚焦区和肩区扩展位块传输操作将位于所述表示中的所述边界内的所述表示内的信息复制到所述聚焦区和所述晶状体表面的所述肩区上; 以及在显示屏幕上显示变换后的呈现以生成关注区域的呈现。
