Reasoning with Projected Contours
Projected contours enable Euler diagrams to scale better. They enable the representation of information using less syntax and can therefore increase visual clarity. Here informal r...

Contour generators of evolving implicit surfaces
The contour generator is an important visibility feature of a smooth object seen under parallel projection. It is the curve on the surface which seperates front-facing regions fro...

Positive Semantics of Projections in Venn-Euler Diagrams
Venn diagrams and Euler circles have long been used as a means of expressing relationships among sets using visual metaphors such as \disjointness" and \containment" of t...

Projections in Venn-Euler Diagrams
Venn diagrams and Euler circles have long been used to express constraints on sets and their relationships with other sets. However, these notations can get very cluttered when we...

Contour line thinning and multigrid generation of raster-based digital elevation models
Thin plate spline interpolation is a widely used approach to generate a digital elevation model (DEM) from contour lines and scattered data. In practice, contour maps are scanned a...
