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; selecting a location for the region-of-interest; creating a lens surface having a predetermined location for the region-of-interest; creating a transformed presentation by: determining a mapping for pixel coordinates from the representation to the lens surface by applying a distortion function defining said lens surface to said pixel coordinates; calculating a vector from the predetermined location to the location; and, copying pixel information from the representation to the lens surface according to the mapping as displaced by the vector; and, displaying the transformed presentation on a display screen to generate the presentation of the region-of-interest.
摘要（中）：
一种用于在信息表示中生成兴趣区域的呈现的方法，包括以下步骤：为所述感兴趣区域选择视点; 选择兴趣区域的位置; 创建具有用于感兴趣区域的预定位置的透镜表面; 通过以下方式创建变换的呈现：通过将限定所述透镜表面的失真函数应用于所述像素坐标来确定从所述表示到所述透镜表面的像素坐标的映射; 从所述预定位置计算向量到所述位置; 并且根据由向量偏移的映射将像素信息从表示复制到透镜表面; 并且在显示屏幕上显示经变换的呈现以生成感兴趣区域的呈现。
