See the public types, functions, attributes, and inheritance diagram of vtkMatrix4x4 class. I found a source that gave several C# (CSharp) vtkMatrix4x4. Many of the methods take an array of 16 doubles in row // . The ResliceAxes are used most often to permute the data, e. h:402. vtkIntArray * ComponentIndexArray vtkIntArray * SourceInstanceArray vtkMatrix4x4 * vtkNIFTIImageReader::GetSFormMatrix () inline: Get a matrix that gives the "sform" orientation and offset for the data. e. This demo produces target points (green) which are at the origin and unit length along each axis. Numpy array containing the data from matrix.
