Detailed Description

Nodemap class used when remeshing. The map associates the indices of nodes in the old mesh with indices of nodes in the new mesh.

Member Data Documentation

bool NodeMap::mIsIdentity

private

Redundant data to provide a shortcut when the map is empty or the identity. This is initialised to true, since an empty map is equivalent to the identity.

Definition at line 56 of file NodeMap.hpp.

Referenced by GetNewIndex(), IsIdentityMap(), ResetToIdentity(), SetDeleted(), and SetNewIndex().

std::vector<unsigned> NodeMap::mMap

private

The map is stored as an ordered vector of node indices. Note that a vector is more efficient than std::map in this case where we know the exact size of the map and can benefit from O(1) lookup
