Member Function Documentation

const SbMat3& SbMatrix3::getValue

(

)

const [inline]

Returns 3x3 array of elements.

void SbMatrix3::getValue

(

SbMat3 &

m

)

const

Returns 3x3 array of elements.

static SbMatrix3 SbMatrix3::identity

(

)

[static]

Returns an identity matrix.

void SbMatrix3::makeIdentity

(

)

Sets matrix to be identity.

SbMatrix3& SbMatrix3::multLeft

(

const SbMatrix3 &

m

)

Pre-multiplies matrix by the given matrix.

Matrix is replaced by the result.

void SbMatrix3::multMatrixVec	(	const SbVec3f &	src,
		SbVec3f &	dst
	)			const

Post-multiplies matrix by the given column vector, giving a 3D vector result.

It is safe to let src and dst be the same instance of SbVec3f.

SbMatrix3& SbMatrix3::multRight

(

const SbMatrix3 &

m

)

Post-multiplies the matrix by the given matrix.

Matrix is replaced by the result.

void SbMatrix3::multVecMatrix	(	const SbVec3f &	src,
		SbVec3f &	dst
	)			const

Pre-multiplies matrix by the given row vector, giving a 3D vector result.

It is safe to let src and dst be the same instance of SbVec3f.

SbMatrix3::operator float *

(

)

[inline]

Cast: returns pointer to storage of first element.

SbMatrix3::operator SbMat3 &

(

)

[inline]

Cast: returns reference to 3x3 array.

SbVec3f SbMatrix3::operator*

(

const SbVec3f &

v

)

Multiplies matrices by vector, returning a matrix result.

Return M*v

SbMatrix3& SbMatrix3::operator*=

(

const SbMatrix3 &

m

)

[inline]

Post-multiplies the matrix by the given matrix (equivalent to multRight() method).

Matrix is replaced by the resulting matrix.

(

const SbRotation &

q

)

[inline]

Set the matrix from an SbRotation.

SbMatrix3& SbMatrix3::operator=

(

const SbMatrix3 &

m

)

SbMatrix3& SbMatrix3::operator=

(

const SbMat3 &

m

)

Sets value from 3x3 array of elements.

const float* SbMatrix3::operator[]

(

int

i

)

Make it look like a usual matrix (so you can do m[2][2]).

float* SbMatrix3::operator[]

(

int

i

)

[inline]

Make it look like a usual matrix (so you can do m[2][2]).

void SbMatrix3::print

(

FILE *

fp

)

const

Prints a formatted version of the matrix to the given file pointer.

void SbMatrix3::setScale

(

const SbVec3f &

s

)

Sets matrix to scale by given vector.

void SbMatrix3::setScale

(

float

s

)

Sets matrix to scale by given uniform factor.

void SbMatrix3::setValue

(

const float *

pMat

)

[inline]

Sets value from a 9 value float array.

void SbMatrix3::setValue

(

const SbMat3 &

m

)

Sets value from 3x3 array of elements.
