Member Function Documentation

void RTMigr::AddIPInfo	(	MigrInnerGrid	ip_grid,
		IPCell *	ip_info,
		int	ip_cell_num
	)

addition of incident-point-cell structures array to a two-dimentional grid of migration-cell structures (incident points grid); in this case, field 'f' in each migration-cell structure contains out-ray angle; double-path cases are available: a few angle-time data may appear for one incident-point-cell

void RTMigr::CompMigrGrid	(	MigrCell *	grid1,
		int	size1,
		MigrCell *	grid2,
		int	size2,
		IPCell *&	ip_info,
		int &	ip_cell_num,
		int	i_beg = `-1`,
		int	i_end = `-1`
	)

comparison of two migration grids (shot point and reciever) to check the Snellius condition execution; the results are placed in incident-point-cell structures array

int RTMigr::GetIMax ( )

returns maximal horisontal index of migration cell

double RTMigr::GetIPValue	(	int	spN,
		int	i,
		int	j,
		MigrInnerCell	cell
	)

returns amplitude value for the cell [i][j]: the well is shooted from the center point of the incident-point-cell: ray angles vary from (cell.f-migrAngle) to (cell.f+migrAngle); for each "shooted" reciever a full ray path time (from shot point up to reciever) is obtained; from the corresponding seismic trace, the amplitude value is obtained in accordance to the full ray path time; amplitudes value for all "shooted" recievers are summarized

int RTMigr::GetJMax ( )

returns minimal vertical index of migration cell

MigrGridArea RTMigr::GetMGArea ( )

returns special structure, describing migration grid for current model; is used in result saving

bool RTMigr::GetMigrGrid	(	double	x,
		double	z,
		WAVE_TYPE	wType,
		MigrCell *&	grid,
		int &	size
	)

(x,z)-point migration grid calculation (TRUE - success)

bool RTMigr::GetMigrGrid	(	double	x,
		double	z,
		WAVE_TYPE	wType,
		MigrInnerGrid &	grid
	)

(x,z)-point migration grid calculation (TRUE - success). Does not use seismic object (can be simply used to cover 2d space with rays).

bool RTMigr::GetMigrGridRec	(	int	recNum,
		MigrCell *&	grid,
		int &	size
	)

reciever migration grid calculation (TRUE - success)

bool RTMigr::GetMigrGridSP	(	int	sp_num,
		MigrCell *&	grid,
		int &	size
	)

shot point migration grid calculation (TRUE - success)

Vel2dModel* RTMigr::GetMod2d ( ) const

inline

returns pointer to the 2d-model

bool RTMigr::GetReady ( )

returns object status flag (UNUSED)

AbstractSeis* RTMigr::GetSeis ( )

returns pointer to the special object, containing seismic traces information

void RTMigr::RecalculateIPGrid ( MigrInnerGrid ip_grid )

incident points grid analysis and recalculation: if the cell contains a few angle-time data, they would be averaged
