Detailed Description

Function Documentation

bool grid	(	REAL	stepX = 0,
		REAL	stepY = 0,
		REAL	percent = 2,
		const char *	gridname = NULL
	)

Tcl syntax:

grid stepX stepY percent

Description:

constructs grid with cells size stepX and stepY. Resulting grid will cover all loaded datasets with overcome border.

Parameters

stepX	cell length in X direction
stepY	cell length in Y direction
percent	border length in percent
gridname	name of grid

bool grid2	(	REAL	stepX = 0,
		REAL	stepY = 0,
		REAL	percent = 2,
		const char *	gridname = NULL
	)

Tcl syntax:

grid2 stepX stepY percent

Description:

constructs grid with cells size stepX and stepY. Resultin grid will cover all loaded datasets with overcome border. Number of nodes in each direction is a number equal to , where n is an integer number.

Parameters

stepX	cell length in X direction
stepY	cell length in Y direction
percent	border length in percent
gridname	name of grid

bool grid_get	(	REAL	startX,
		REAL	endX,
		REAL	stepX,
		REAL	startY,
		REAL	endY,
		REAL	stepY,
		const char *	gridname = NULL
	)

Tcl syntax:

grid_get startX endX stepX startY endY stepY "gridname"

Description:

constructs grid

Parameters

startX	X-coordinate of the first node of the grid
endX	X-coordinate of the last node of the grid
stepX	distance between two neighbour X-nodes
startY	Y-coordinate of the first node of the grid
endY	Y-coordinate of the last node of the grid
stepY	distance between two neighbour Y-nodes
gridname	name for grid (optional)

bool grid_get2	(	REAL	startX,
		REAL	endX,
		REAL	stepX,
		REAL	startY,
		REAL	endY,
		REAL	stepY,
		const char *	gridname = NULL
	)

Tcl syntax:

grid_get startX endX stepX startY endY stepY "name"

Description:

constructs grid. Number of nodes in each direction is a number equal to , where n is an integer number.

Parameters

startX	X-coordinate of the first node of the grid
endX	X-coordinate of the last node of the grid
stepX	distance between two neighbour X-nodes
startY	Y-coordinate of the first node of the grid
endY	Y-coordinate of the last node of the grid
stepY	distance between two neighbour Y-nodes
gridname	name for grid (optional)

bool grid_get_for_pnts	(	int	Xnodes,
		int	Ynodes,
		const char *	points_name = "*",
		const char *	gridname = NULL
	)

Tcl syntax:

grid_get_for_pnts Xnodex Ynodes "points_name" "gridname"

Description:

constructs grid which covers points, and consists of Xnodes*Ynodes nodes.

bool grid_get_for_pnts_step	(	REAL	stepX,
		REAL	stepY,
		const char *	points_name = "*",
		const char *	gridname = NULL
	)

Tcl syntax:

grid_get_for_pnts_step steX stepY "points_name" "gridname"

Description:

		const char *	gridname = NULL
	)

Tcl syntax:

grid_get_from_surf

Description:

constructs grid equal to surface grid
