# A3DCompareInputData

struct `A3DCompareInputData`

  `A3DCompareInputData`structure that contains input data of `A3DCompareFaces()`.

  The two fields m_pOldRiBrepModelPlacements and m_pNewRiBrepModelPlacements must each point to an array of 4x4 matrices (column major). The size of the original array is respectively m_uiOldRiBrepModelsSize and m_uiNewRiBrepModelsSize, each array element represents the matrix as a 16 long `A3DDouble`array.
