Real-time Fault Editing in a Tetrahedralised Volume

@inproceedings{TertoisRM2005b,
 abstract = { As the understanding of a geological system deepens with the addition of new information, one can realise that the geometry of a fault in a tetrahedralised volume is slightly off. Rather than having to edit the original fault surface and create a new model from scratch, directly editing the volume would save time and be much more comfortable for the user. Indeed, real-time editing enables a precise control over the deformation of objects, and visual feedback lets the user stop editing when the result is satisfactory. A free-form deformation technique was developed to implement this interaction. The user simply picks and drags a point on the fault, and the volume is locally updated in real-time. A distance map is computed over the volume to confine the deformation to a zone around the fault to be edited. A new DSI constraint maintains model consistency throughout editing by making sure the sign of the algebraic volume of the tetrahedrons does not invert during edition. A smoothness constraint distributes the displacement in the whole active region. Additional constraints prevent the user from modifying the geometry of faults other than the one under edition. },
