Resumo: | |||||||||||||
A good mesh representation of tridimensional objects is necessary not only
to render algorithms but also to support numerical simulations. Objects captured
via sensors, e.g., seismic acquisition and laser scanning, have an intrinsic error in
its representation of objects. Furthermore, this unprocessed data does not generate
a good description of the objects, portraying it inadequately or incorrectly. The
existing literature on resampling representations contains various techniques to resolve
this problem. In particular, a general approach using triangle mesh has recently
gained attention. One benefit of this technique is its mathematical guarantees
generating triangles meshes that closely approximate Delaunay triangles. The main
drawback to this technique occurs in its application to objects with borders, such
as holes or mesh intersections. In this work, we present a new method to re-mesh
the object representation taking into account the simplification of the curves that
represent the holes. We apply this technique to seismic horizon data.
