- removed old alternative to Catmark feature adaptive selection
- removed unused methods from Vtr::SparseSelector
- made use of Level::VTag's new "incomplete" member in both

|
|
// Class supporting "selection" of components in a Level for sparse Refinement.
|
|
// The term "selection" here implies interest in the limit for that component, i.e.
|
|
// the limit point for a selected vertex, the limit patch for a face, etc. So this
|
|
// class is responsible for ensuring that all neighboring components required to
|
|
// support the limit of those selected are included in the refinement.
|
|
//
|
|
// This class is associated with (and constructed given) a Refinement and its role
|
|
// is to initialize that Refinement instance for eventual sparse refinement. So it
|
|
// is a friend of and expected to modify the Refinement as part of the selection.
|
|
// Given its simplicity and scope it may be worth nesting it in Vtr::Refinement.
|
|
//
|
|
// While all three component types -- vertices, edges and faces -- can be selected,
|
|
// only selection of faces is currently used and actively supported as part of the
|
|
// feature-adaptive refinement.
