Detailed Description

Function Documentation

◆ operator<<()

std::ostream & stir::operator<<	(	std::ostream &	out,
		const RigidObject3DTransformation &	rigid_object_transformation
	)

Output to (text) stream.

Will be written as

{ quaternion, translation }

References stir::RigidObject3DTransformation::get_quaternion(), and stir::RigidObject3DTransformation::get_translation().

◆ operator>>()

std::istream & stir::operator>>	(	std::istream &	,
		RigidObject3DTransformation &	rigid_object_transformation
	)

Input from (text) stream.

Should have format

{ quaternion, translation }

◆ compose()

RigidObject3DTransformation stir::compose	(	const RigidObject3DTransformation &	apply_last,
		const RigidObject3DTransformation &	apply_first
	)

Composition of 2 transformations.

This provides a way to perform 2 transformations after eachother. The following code will work

RigidObject3DTransformation tf_1,tf_2; // initialise somehow
const RigidObject3DTransformation tf_2_1 = compose(tf_2,tf_1));
  const CartesianCoordinate3D<float> point(1.F,-5.F,2.F);
  assert(norm(tf_2.transform_point(tf_1.transform_point(point)) -
              tf_2_ 1.transform_point(point))
         < .01);

◆ transform_3d_object_push_interpolation()

template<class ObjectTransformationT , class PushInterpolatorT >

Succeeded stir::transform_3d_object_push_interpolation	(	DiscretisedDensity< 3, float > &	out_density,
		const DiscretisedDensity< 3, float > &	in_density,
		const ObjectTransformationT &	transformation_in_to_out,
		const PushInterpolatorT &	interpolator,
		const bool	do_jacobian
	)

inline

transform image data

the interpolator has to push values from the input into the output image

Warning: transformation_in_to_out has to transform from in to out

See also: PushTransposeLinearInterpolator for an example interpolator.

Developer's note: This function is inline to avoid template instantiation problems.

transform image data
