摘要：

This paper describes the RECTANGULAR FISHEYE VIEW for the combined presentation of 2D raster images, 2D vector graphics and text. A detailed presentation of the area of highest user interest (the focus) is integrated into a lower-detail context display providing an overview. Screen space is saved by downscaling (distorting) the context. The geometric layout of the view is assembled using rectangular regions. Three different context modes are proposed to provide for computational scalability. Performance and quality implications of two different implementation options are compared.
