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.
