Detailed Description

template<typename S, unsigned dim>
class olb::opti::SparseGeometrySerializer< S, dim >

This class serializes the cells which are marked by indicator.

It produces a smaller control vector, but access is more expensive compared to SimpleGeometrySerializer.

Template Parameters

S	Floating point type
dim	Geometrical dimension
