Towards an homogeneous handling of under-constrained and well-constrained systems of geometric constraints

Abstract: International audienceMost of the geometric constraints solvers consider systems of constraints well-constrained modulo the rigid motions group, and either halt on error when they encounter under-constrained sub-systems, or attempt to add parameterized constraints so as to get rid of the under-constriction. We studied transformations groups making well-constrained some problems that are usually considered as under-constrained. This leads to new algorithms which allow an homogeneous handling of systems of geome… Show more

“…To characterize the invariance of any system, it is necessary to be able to express an appropriate group of invariance for the system by considering local groups. This approach is the perspective of this work to deal with under-constrained problems, as was begun in [TMS07].…”

“…Different kinds of rigidity have been defined, such as minimal or global rigidity. See examples of different definition for rigidity in the works of Servatius [107], Jackson [54], Laman [81], Hoffmann et al, [46], Whiteley, [133], Thierry, [122], Sitharam et al, [40], Michelucci et al, [91] and Zhang, [136].…”
