Supporting detail-in-context for the DNA representation, H-curves

This paper presents a tool for the visual exploration of DNA sequences represented as H-curves [7]. Although very long sequences can be plotted using H-curves, micro-features are lost as sequences get longer. We present a new three-dimensional distortion algorithm to allow the magnification of a sub-segment of an H-curve while preserving a global view of the curve. This is particularly appropriate for H-curves as they provide useful visual information at several resolutions. Our approach also extends the current possibilities of detail-in-context viewing in 3D. It provides a non-occluding, orthogonal technique that preserves uniform scaling within regions and maintains geometric continuity between regions.
