Topological simplification of isosurfaces in volumetric data using octrees
Volumetric data, such as output from CT scans or laser range scan processing methods, often have isosurfaces that contain topological noise--small handles and holes that are not p...

Dual Contouring with Topology-Preserving Simplification Using Enhanced Cell Representation
We present a fast, topology-preserving approach for isosurface simplification. The underlying concept behind our approach is to preserve the disconnected surface components in cel...

A Lipschitz Method for Accelerated Volume Rendering
Interpolating discrete volume data into a continuous form adapts implicit surface techniques for rendering volumetric iso-surfaces. One such algorithm uses the Lipschitz condition...

Efficient representation and extraction of 2-manifold isosurfaces using kd-trees
In this paper, we propose the utilization of a kd-tree based hierarchy as an implicit object representation. Compared to an octree, the kd-tree based hierarchy is superior in term...

Simplifying Flexible Isosurfaces Using Local Geometric Measures
our tree, an abstraction of a scalar field that encodes the nesting relationships of isosurfaces, can be used to accelerate isosurface extraction, to identify important isovalues ...
