Zeta: a Resolution Modeling System
Introduction
Zeta is a prototypal Resolution Modeling system,
implemented by the Visual
Computer Group of CNUCE/IEI - C.N.R. at Pisa.
Zeta supports the construction of variable resolution models
out of a multiresolution mesh represented adopting the hypertriangulation
scheme.
Zeta supports:
-
efficient extraction of fixed
resolution meshes out of the multi-res model;
-
unified and interactive management
of selective refinements or simplification;
-
easy composition of the
selective ref./simpl. actions;
-
guaranteed C0 continuity (i.e. no
cracks) of the variable resolution mesh produced;
-
shape editing capabilities, integrated with the multiresolution representation;
-
interactive response times.
Our Resolution Modeling approach and the Zeta system are presented
in detail in the paper: P. Cignoni, C. Montani, C.
Rocchini, R. Scopigno, Zeta: a Resolution Modeling system, GMIP:
Graphical Models and Image Processing, vol.60(5), September 1998, pp.305-329.
The Resolution Modeling prototype (rel
1.0) is available
on the web (SGI executables only for IRIX 6.2).
Users are kindly requested to send comments, acknoledgements of possible
bugs, etc. to: R.Scopigno@cnuce.cnr.it
