DESCRIPTION
A field containing a transformation matrix (an SbMatrix).

SoSFMatrices are written to file as 16 floating point numbers separated by whitespace. For example, an identity matrix is written as:

1 0 0 0  0 1 0 0  0 0 1 0  0 0 0 1

METHODS
void
setValue(float a11, float a12, float a13, float a14, float a21, float a22, float a23, float a24, float a31, float a32, float a33, float a34, float a41, float a42, float a43, float a44)
Sets this field to contain the matrix given by the 16 values. For a translation matrix, the x, y and z translations should be in the a41, a42, and a43 arguments.

static SoType
getClassTypeId()
virtual void
getTypeId() const
Returns the type for this class or a particular object of this class.

const SbMatrix &
getValue() const
Returns this field's value.

const SbMatrix &
operator =(const SbMatrix & newValue)
void
setValue(const SbMatrix & newValue)
Sets this field to newValue.

int
operator ==(const SoSFMatrix &f) const
int
operator !=(const SoSFMatrix &f) const
Returns TRUE if f is of the same type and has the same value as this field.
