Function Documentation

SPI_CAL_distance_point_profile()

double SPI_CAL_distance_point_profile	(	int	pos,
		int	plane,
		double *	pt )

Calculates the minimum distance between a point and a profile.

Parameters

[in]	pos	index of a profile element in the database
[in]	plane	plane of the point used to calculate the distance
[in]	pt	point of reference

Returns

minimum distance between a point and the profile

dist := RCALL(SPI_CAL_distance_point_profile,ipos,1,pt);

SPI_CAL_gravity_profile()

void SPI_CAL_gravity_profile	(	int	pos,
		double *	pt )

Calculates the point of the center of gravity of the profile.

Parameters

[in]	pos	index of a profile element in the database
[out]	pt	point of center of gravity (TR3)

PCALL(SPI_CAL_gravity_profile,ipos,pt);

SPI_CAL_sort_point()

double SPI_CAL_sort_point	(	int	sortType,
		int	indTab1stPt,
		int	indTab2ndPt )

Optimizes an array of points and returns the total distance.

Parameters

[in]	sortType	sorting method 1 Back and forth grid X + and Y + 2 Grid back and forth X- and Y + 3 Back and forth grid X + and Y- 4 Grid go back X- and Y- 5 Single aisle grid X + and Y + 6 Single aisle grid X- and Y + 7 Single aisle grid X + and Y- 8 Single aisle grid X- and Y- 9 Back and forth grid Y + and X + 10 Grid back and forth Y + and X- 11 Back and forth grid Y- and X + 12 Grid back and forth Y- and X- 13 Single aisle grid Y + and X + 14 Single aisle grid Y + and X- 15 Single aisle grid Y- and X + 16 Single aisle grid Y- and X- 17 Auto Optimization 18 Euclidean Distance 19 TaxiDistance 20 DistanceSup 21 Euclidean Distance with bipoint 22 TaxiDistance with bipoint 23 DistanceSup with bipoint
[in]	indTab1stPt	index of the table containing the starting points
[in]	indTab2ndPt	index of the table containing the end points (in case of profiles), or -1

Returns

total distance between points

ind_tab := ICALL(SPI_LOC_find_first_array);
Ier  := ICALL(SPI_LOC_alloc_array,SPI_LOC_TYPTR3,4,ind_tab);
ier  := ICALL(SPI_LOC_write_one_in_array,0,pt1,ind_tab);
ier  := ICALL(SPI_LOC_write_one_in_array,1,pt2,ind_tab);

ier  := ICALL(SPI_LOC_write_one_in_array,3,pt4,ind_tab);
dist := RCALL(SPI_CAL_sort_point,17,ind_tab,-1);

The table ind_tab now contains the points sorted according to the method "Auto Optimization"

SPI_CAL_surface_profile()

double SPI_CAL_surface_profile	(	int	pos,
		int	plane )

Calculates the area of a profile.

Parameters

[in]	pos	index of a profile element in the database
[in]	plane	reference plane

Returns

SIGNED value of the profile ( < 0 Trigo > 0 clockwise)

Remarks

If the profile is open it will be closed artificially by a segment

rval := RCALL(SPI_CAL_surface_profile,ipos,1);
