There is no function to do that in geogram, A possible strategy is to compute a score for each triangle edge (depending on both co-planarity of the triangles and angles at the four corners). Then you can try a greedy strategy (sort all edges by score, then merge the best ones in order). There is also a more complicated algorithm (called "perfect matching") that will maximize the total score. It is used in the following article: |

Hello,
We had used blossom quad algorithm, but without CVT. So it was not giving
desired results. So geogram can only generate triangular mesh?

After remeshing, how do I combine triangular elements to get quads
