Member Function Documentation

void TransformIF::translate ( const RealVect a_trans  ) 

Translate by a_trans

void TransformIF::scale ( const Real a_scale  ) 

Scale (uniformly) by a_scale

void TransformIF::scale ( const RealVect a_scale  ) 

Scale in each direction (idir) by a_scale[idir]

void TransformIF::rotate ( const Real a_angle,
const RealVect a_point = RealVect::Zero,
const RealVect a_axis = BASISREALV(0) 
)

In 2D - rotate by a_angle about a_point, a_axis is ignored. In 3D - rotate by a_angle about the line in space specified by a_point and and a_axis.

void TransformIF::rotate ( const RealVect a_axis1,
const RealVect a_axis2,
const RealVect a_point = RealVect::Zero 
)

About a_point, Rotate vector a_axis1 to align with vector a_axis2
