Member Function Documentation

void vtkMatrix4x4::Adjoint (  vtkMatrix4x4 *    in, vtkMatrix4x4 *    out )  [inline]

Compute adjoint of the matrix and put it into out.

void vtkMatrix4x4::DeepCopy (  const double    Elements[16] )  [inline]

Non-static member function. Assigns *from* elements array

void vtkMatrix4x4::DeepCopy (  vtkMatrix4x4 *    source )  [inline]

Set the elements of the matrix to the same values as the elements of the source Matrix.

double vtkMatrix4x4::Determinant (    )  [inline]

Compute the determinant of the matrix and return it.

virtual const char* vtkMatrix4x4::GetClassName (    )  [virtual]

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkObject.

double vtkMatrix4x4::GetElement (  int    i, int    j )  const [inline]

Returns the element i,j from the matrix.

void vtkMatrix4x4::Identity (    )  [inline]

Set equal to Identity matrix

void vtkMatrix4x4::Invert (  vtkMatrix4x4 *    in, vtkMatrix4x4 *    out )  [inline, static]

Matrix Inversion (adapted from Richard Carling in "Graphics Gems," Academic Press, 1990).

virtual int vtkMatrix4x4::IsA (  const char *    type )  [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkObject.

int vtkMatrix4x4::IsTypeOf (  const char *    type )  [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkObject.

void vtkMatrix4x4::Multiply4x4 (  vtkMatrix4x4 *    a, vtkMatrix4x4 *    b, vtkMatrix4x4 *    c )  [inline, static]

Multiplies matrices a and b and stores the result in c.

float* vtkMatrix4x4::MultiplyPoint (  const float    in[4] )  [inline]

For use in Java, Python or Tcl. The default MultiplyPoint() uses a single-precision point.

void vtkMatrix4x4::MultiplyPoint (  const float    in[4], float    out[4] )  [inline]

Multiply a homogeneous coordinate by this matrix, i.e. out = A*in. The in[4] and out[4] can be the same array.

vtkMatrix4x4* vtkMatrix4x4::New (    )  [static]

Construct a 4x4 identity matrix. Reimplemented from vtkObject.

void vtkMatrix4x4::PointMultiply (  const float    in[4], float    out[4] )

For legacy compatibility. Do not use.

void vtkMatrix4x4::PrintSelf (  ostream &    os, vtkIndent    indent )  [virtual]

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from vtkObject.

vtkMatrix4x4* vtkMatrix4x4::SafeDownCast (  vtkObject *    o )  [static]

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkObject.

void vtkMatrix4x4::SetElement (  int    i, int    j, double    value )  [inline]

Sets the element i,j in the matrix.

void vtkMatrix4x4::Transpose (  vtkMatrix4x4 *    in, vtkMatrix4x4 *    out )  [inline, static]

Transpose the matrix and put it into out.

void vtkMatrix4x4::Zero (    )  [inline]

Set all of the elements to zero.
