Detailed Description

Applies piecewise smooth loop subdivision rules.

Warning: The implementation assumes that vertices which are passed to 'refinement_begins' still exist in the underlying grid when 'refinement_ends' is called.

◆ refinement_begins()

void ug::SubdivisionProjector::refinement_begins ( const ISubGrid * sg )

virtual

called before refinement begins

if not NULL, the specified sub-grid will contains all elements that will be refined and are affected by the given projector.

If the specialized implementation of refinement_begins requires this subgrid, the method 'refinement_begins_requires_subgrid' should be specialized and should return 'true'. In this case the subgrid should always be provided by the caller. If you call 'RefinementProjector::refinement_begins(sg);' at the beginning of your specialization, an error will be thrown if this is not the case.

returns 'true' if a specialized projector requires the subgrid during its 'refinement_begins' method.

Note: Implementers of derived classes should overload this method and return 'true' if their 'refinement_begins' method requires a subgrid. Please have a look at the documentation of 'RefinementProjector::refinement_begins' for more information.
