JADE V2.1 -- multiresolution decimation based on global error |
| Capabilities | The package provides an algorithm for
simplifying triangular meshes. Given an input model and a user-specified
error tolerance, JADE generates an output model that attempts to reduce
considerably the number of polygons while staying within the specified
error tolerance. JADE's main features are : - accurate estimation of the approximation error; - high reduction factor; - multiresolution output; - wide generality and good space/time efficency. |

Resolution Modeling |
|
| Topic | ZETA - a Resolution Modeling system |
| Capabilities | 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 represetation; - interactive response times. |
