Methods and apparatus are disclosed for presenting information with varying levels of detail based on one or more regions of interest. A virtual viewport of the information to be displayed is mapped onto a three-dimensional surface; and the mapped information is projected in one dimension onto a display. The plurality of levels of detail include, for example, an expansion zone associated with a region of interest and a compression zone for portions of the information that are removed from a region of interest. The plurality of levels of detail are based on a shape of the three-dimensional surface. In one implementation, the three-dimensional surface is a three-dimensional cylindrical surface. The three-dimensional surface is reshaped to vary the degree of compression by varying a slope of the three-dimensional surface in the z-dimension.
