Detailed Description

Mesh converter.

Converts a mesh with triangles into a mesh with quadrilaterals only. Each triangle is split into three quads by joining the edge midpoints and the center of gravity.

If the attribute of a triangle which is subdivided is 0, the newly created middle vertex, the edges and the quads inherit the key of the triangle as attribute. Otherwise, they inherit the attribute of the triangle.

This class can handle triangular and quadrilateral input meshes. If a quad is met, there is nothing to do. At the moment, mixed meshes cannot be handled.

Todo:

Implement methods to handle mixed meshes (quads and triangles)
