Build the quad mesh from the given scaffold mesh.
Build the full mesh with the help of the scaffold mesh coming from the triangle mesh generator, Triangle. To build this quad element based mesh we make use of the fact that a triangle element can be split as shown in the diagram below:
N2 | | N0 : 1st scaffold element node | | N1 : 2nd scaffold element node | | N2 : 3rd scaffold element node | | C | Q_2 | B Edge 0 : N0 –> N1 | | | | Edge 1 : N1 –> N2 | | | | Edge 2 : N2 –> N0 | | | | | | | | A : Midpoint of edge 0 | Q_0 | Q_1 | B : Midpoint of edge 1 | | | C : Midpoint of edge 2 | | | N0 __________|__________ N1 A
The intersection of all three quad elements is the centroid. Using this splitting, the subsequent mesh will consist of quadrilaterals whose shape which depend on the structure of the underlying mesh.
