How do I convert a 2D mesh of triangles into quadrilaterals?


How do I convert a 2D mesh of triangles into quadrilaterals? Is this the best approach or it is even possible to generate a 2D quadrilateral mesh from scratch?

Solution

  • As part of their paper on Quad Mesh Simplification, Tarini et al. present a section on Tri to Quad mesh conversion (Section 6 to be precise).
    You can find the paper on the author's website here: "Practical quad mesh simplification" (PDF).

    The Open Source implementation should be available as part of MeshLab.
