Interpolate to all the fine cells within one coarse cell.
Fill the fine cells inside a_coarseDataCell with interpolated data from a_coarseFab.
The fine cells to be filled in are at m_baseFineBox + m_refineVect * a_coarseDataCell + a_coarseToFineOffset. The coarse cells from which we draw data are (a_coarseDataCell + m_coarseBaseIndices[i*D+[0:D-1]]: 0 <= i < m_stencilSize).
a_fineFab | to fill at m_baseFineBox + m_refineVect*a_coarseDataCell + a_coarseToFineOffset |
a_coarseFab | coarse data |
a_coarseDataCell | coarse cell with fine subcells to fill in |
a_coarseToFineOffset | offset from base coarse cell to coarsened fine cells |
