Detailed Description

Field containing a 4x4 matrix.

A field containing a transformation matrix (an SbMatrix).

SoSFMatrixs 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

Member Function Documentation

static SoType SoSFMatrix::getClassTypeId (  )  [static]

Returns the type identifier for this class.

Reimplemented from SoSField.

virtual SoType SoSFMatrix::getTypeId (  )  const [virtual]

Returns the type identifier for this specific instance.

Implements SoTypedObject.

const SbMatrix& SoSFMatrix::getValue (  )  const [inline]

Returns this field's value.

virtual size_t SoSFMatrix::getValueSize (  )  const [inline, virtual]

Get size of the value.

Reimplemented from SoField.

int SoSFMatrix::operator!= ( const SoSFMatrix f  )  const [inline]

Returns FALSE if otherField is of the same type and has the same value as this field.

Reimplemented from SoField.

const SbMatrix& SoSFMatrix::operator= ( const SbMatrix newValue  )  [inline]

Sets this field to newValue.

const SoSFMatrix& SoSFMatrix::operator= ( const SoSFMatrix f  ) 

Copy from another field of same type.

int SoSFMatrix::operator== ( const SoSFMatrix f  )  const

Returns TRUE if otherField is of the same type and has the same value as this field.

Reimplemented from SoField.

void SoSFMatrix::setValue ( const SbMatrixd md  ) 

Convenience method that allows you to specify a field value using a double precision variable.

Note that Open Inventor fields still store only single precision values, not double precision values. The specified value is converted to single precision, then stored.

void SoSFMatrix::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.

void SoSFMatrix::setValue ( const SbMatrix newValue  ) 

Sets this field to newValue.
