Two Methods for Iso-Surface Extraction from Volumetric Data and Their Comparison
Vaclav Skala, Alex Brusi
There are various methods for extracting iso-surfaces from volumetric data. Marching cubes or tetrahedra or raytracing methods are mostly used. There are many specific techniques t…
A New Radial Basis Function Approximation with Reproduction
Zuzana Majdisova, Vaclav Skala
Approximation of scattered geometric data is often a task in many engineering problems. The Radial Basis Function (RBF) approximation is appropriate for large scattered (unordered)…
O(lgN) Line Clipping Algorithm in E2
Vaclav Skala
A new O(lg N) line clipping algorithm in E2 against a convex window is presented. The main advantage of the presented algorithm is the principal acceleration of the line clipping p…
A Fast Algorithm for Line Clipping by Convex Polyhedron in E3
Vaclav Skala
A new algorithm for line clipping against convex polyhedron is given. The suggested algorithm is faster for higher number of facets of the given polyhedron than the traditional Cyr…
A Comparative Study of LOWESS and RBF Approximations for Visualization
Michal Smolik, Vaclav Skala, Ondrej Nedved
Approximation methods are widely used in many fields and many techniques have been published already. This comparative study presents a comparison of LOWESS (Locally weighted scatt…
A two-level approach to implicit surface modeling with compactly supported radial basis functions
Rongjiang Pan, Vaclav Skala
We describe a two-level method for computing a function whose zero-level set is the surface reconstructed from given points scattered over the surface and associated with surface n…
