Abstract: | Mesh simplification is one of the most important links in the context of reverse engineering. It is also an important consideration
in computer graphics. This paper presents a novel and original method of triangular mesh reduction. A new concept of super-face
is defined. In order to construct a super-face, a way to calculate the scattered point curvature is discussed. The growth
of a seed point and the combination of different regions are also necessary for the construction of a super-face. When the
hole left by the deletion of super-face is retriangulated a genetic algorithm is used that has been modified for our specific
problem. Then the different weights to balance the optimisation of the new triangular mesh can be adjusted. |
