float  a12,
float  a13,
float  a21,
float  a22,
float  a23,
float  a31,
float  a32,
float  a33 
)

Constructor.

SbMatrix3::SbMatrix3 ( const SbMat3 m  ) 

Constructor.


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.

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.

SbMatrix3& SbMatrix3::operator= ( const SbRotation q  )  [inline]

Set the matrix from an SbRotation.

SbMatrix3& SbMatrix3::operator= ( const SbMatrix3 m  ) 

Set the matrix from another SbMatrix3.

SbMatrix3& SbMatrix3::operator= ( const SbMat3 m  ) 

Sets value from 3x3 array of elements.

const float* SbMatrix3::operator[] ( int  i  )  const [inline]

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::setRotate ( const SbRotation q  ) 

Sets matrix to rotate by given rotation.

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.

SbMatrix3 operator* ( const SbMatrix3 m1,
const SbMatrix3 m2 
) [friend]

Multiplies two matrices, returning a matrix result.

int operator== ( const SbMatrix3 m1,
const SbMatrix3 m2
