Contour Nest: A Two-dimensional Representation for Three-dimensional Isosurfaces

The FCC sub-lattice The BCC sub-lattice Figure 1: The Cartesian lattice and the structure of the sub- lattices. The FCC has half the sampling density and BCC has a quarter

The centers of the contour (white) pixels are inter- preted as points in 2D and a Multi-level Partition of Unity (MPU) implicit curve (i.e. a 2D field whose zero level set is the

We allocated the different visualization and interaction metaphors to a two-dimensional and a three- dimensional display environment, dependent of the useful- ness or hindrance of

We propose a new method for rendering isosurfaces at interactive rates while supporting dynamic ambient occlusion and/or soft shadows and requiring minimal pre-computation time..

We compared four different input methods for controlling the contour drawing widget and the viewpoint of the surface: using one 2D mouse for drawing and viewpoint selection, using

In this paper, we consider an approach to object detection in an image using a new segmentation (edge detection) al- gorithm based on a space-oriented filter that incorporates a

We propose a purely geometric solution to generate static folded paper geometry from a 2D pattern and a 3D placement of its contour curve.. Fold lines are explicitly identified and

We first develop stochastic distribution functions for char- acterizing the spatial variability of iso-contours in uncer- tain scalar fields, i.e., the spatial cumulative
