◆ set_up()

Succeeded stir::ProjectorByBinPairUsingParallelproj::set_up	(	const shared_ptr< const ProjDataInfo > &	proj_data_info_sptr,
		const shared_ptr< const DiscretisedDensity< 3, float > > &	image_info_sptr )

Stores all necessary geometric info.

If necessary, set_up() can be called more than once.

Derived classes can assume that the projectors will be called with input corresponding to the arguments of the last call to set_up().

Warning: Derived classes have to call set_up from the base class.

Reimplemented from stir::ProjectorByBinPair.
