摘要： A computer-implemented method for computing ridges and valleys of a height field includes a computing platform receiving a plurality of sample points associated with a dataset and an indication of an orientation for referencing the plurality of sample points and applying an interpolation function to the plurality of sample points to determine the height field. The computing platform selects a plurality of seed points associated with the height field and calculates a Hessian matrix of the height field. The Hessian matrix is used by the computing platform to trace (a) one or more ridge curves associated with the height field and (b) one or more valley curves associated with the height field using the plurality of seed points.

摘要： Systems, methods, and computer readable mediums. A method includes receiving a geometric model including at least one removal feature having at least one face, the removal feature being a feature that is removed prior to variational solving and recreated after a variational solution has been applied into the geometric model. The method includes designating at least one face of the removal feature as a remain variational face that will not be removed during a variational edit. The method includes adding a constraint to the remain variational face of the removal feature and performing the variational edit on the model to produce an edited model, including applying the constraint. The method includes storing the edited model.
