Line-Torus Intersection for Ray Tracing: Alternative Formulations
Vaclav Skala
Intersection algorithms are very important in computation of geometrical problems. Algorithms for a line intersection with linear or quadratic surfaces are quite efficient. However…
A Comparison of Fundamental Methods for Iso-surface Extraction
Jan Patera, Vaclav Skala
In this paper four fundamental methods for an iso-surface extraction are compared, based on cell decomposition to tetrahedra. The methods are compared both on mathematically genera…
Robust Surface Reconstruction from Orthogonal Slices
Radek Svitak, Vaclav Skala
The surface reconstruction problem from sets of planar parallel slices representing cross sections through 3D objects is presented. The final result of surface reconstruction is al…
Poseidon: Non-server WEB Forms Off-line Processing System
Vaclav Skala
The proposed Poseidon system is based on email services of filled forms instead of WEB server based services. This approach is convenient especially for small applications or small…
HS-Patch: A New Hermite Smart Bicubic Patch Modification
Vaclav Skala, Michal Smolik, Lukas Karlicek
Bicubic four-sided patches are widely used in computer graphics, CAD/CAM systems etc. Their flexibility is high and enables to compress a surface description before final rendering…
BS-Patch: Constrained Bezier Parametric Patch
Vaclav Skala, Vit Ondracka
Bezier parametric patches are used in engineering practice quite often, especially in CAD/CAM systems oriented to mechanical design. In many cases quadrilateral meshes are used for…
