nodiscard |
given quadrangle ABCD, selects how to best triangulate it: false = by introducing BD diagonal and splitting ABCD on triangles ABD and DBC, true = by introducing AC diagonal and splitting ABCD on triangles ABC and ACD
|
nodiscard |
consider topology and constraints to decide about flip possibility
|
nodiscard |
given quadrangle ABCD, checks whether its edge AC satisfies Delone's condition; if dihedral angles 1) between triangles ABD and DBC and 2) between triangles ABC and ACD differ more than on maxAngleChange then also returns true to prevent flipping from 1) to 2)
