[vtk-developers] Streaming data from vtkMatrix4x4 and vtkMatrix3x3

[David Gobbi]

Hi Bob,

I use a DeepCopy to stream in both directions:

vtkNew<vtkMatrix4x4> matrix;
double elements[16];
// stream from matrix to POD pointer
vtkMatrix4x4::DeepCopy(elements, matrix);
// stream from POD pointer to matrix
matrix->DeepCopy(elements);
