STRUCTURED TETRAEDRAL MESH GENERATION (Scripts) Publisher's description
from Luigi Giaccari
StructTetraMesh is a tool to build structured tetreaedral mesh on cuboid dataset.
StructTetraMesh is a tool to build structured tetreaedral mesh on cuboid dataset. This is usefull in avoiding delaunay 3D triangulation that for this kind of dataset are particularly slow and numerically unstable.
This tool allows a huge speed improvement against delaunayn for 3D points, the output triangulation will also be вЂњslivers-lessвЂќ, this is particularly important for programs that need a conform triangulation like
fem analysis and search structure algorithms.
x,y,z must be vectors, they represent the axis of the cuboid. It is
also very important they need to be sorted. To improve performances there
is no check for sorted vectors so you have to check yourself.
The Cuboid points are stored in the p: N x 3 array, the tetraedral mesh
with points index is stored in tetr: Ntetr x 4 array. First point is
flagged with index one.
