Detailed Description

This implicit function is a tranformed version of the implicit function passed in the constructor. Various transformations (in 2D and 3D) are allowed including translating, scaling, and rotations.

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

virtual Real TransformIF::value ( const RealVect & a_point ) const [virtual]

Return the value of the function at a_point.

Implements BaseIF.

Real TransformIF::value ( const IndexTM< Real, GLOBALDIM > & a_point ) const [virtual]

Return the value of the function at a_point (of type INdexTM).

Reimplemented from BaseIF.

virtual IndexTM<Real,GLOBALDIM> TransformIF::normal ( const IndexTM< Real, GLOBALDIM > & a_point ) const [virtual]

Return the normalized gradient of the function at a_point. The gradients and normals are based on value, which yields outward-pointing normals (which is different the computational computation elsewhere in Chombo).

Reimplemented from BaseIF.

virtual Vector< IndexTM<Real,GLOBALDIM> > TransformIF::gradNormal ( const IndexTM< Real, GLOBALDIM > & a_point ) const [virtual]

Return the gradient of the normal at a_point.

Reimplemented from BaseIF.

virtual BaseIF* TransformIF::newImplicitFunction ( ) const [virtual]

Return a newly allocated derived class. The responsibility for deleting the memory is left to the calling function.

Implements BaseIF.

virtual bool TransformIF::fastIntersection	(	const RealVect &	a_lo,
		const RealVect &	a_hi
	)			const `[virtual]`

Reimplemented from BaseIF.

virtual GeometryService::InOut TransformIF::InsideOutside	(	const RealVect &	a_lo,
		const RealVect &	a_hi
	)			const `[virtual]`

Reimplemented from BaseIF.

void TransformIF::vectorMultiply	(	RealVect &	m_outPoint,
		const Real	m_intrans[SpaceDim+1][SpaceDim+1],
		const RealVect &	m_inPoint
	)			const `[protected]`
