Detailed Description

4D surface abstract object that provides pseudoregular hypergrid generation. Source data is array of 4D points U3dPoint4d(x1, x2, x3, x4). Grid is to be in the form of x4[i,j,k]={x1[i], x2[j], x3[k]}.

Member Function Documentation

void U3dSVRGMathAbstractSurf4d::add_grid_cell ( int  ix1, int  jx2, int  kx3, U3dSVRGMathAbstractSurface::GridCell &  cell  )

protected

Add provided grid cell to current grid with indexies (ix1, jx2, kx3). If any index is < 0 it means that in this direction new point or line is too close (look minGridEps) to other and indexies convet from negative direction as ind_new = -(old_ind+1).

double U3dSVRGMathAbstractSurf4d::calc_nip_x4 ( double  x1, double  x2, double  x3  )

protected

Calculate z-coordinate value of not initial grid point. Current array of initial points is used for calculations. x1, x2 and x3 is 3d coordinates of not initial point.

void U3dSVRGMathAbstractSurf4d::construct_grid ( U3dPoints4dAr &  points )

protected

Construct grid for provided initial points and minimal grid step value provided

virtual void U3dSVRGMathAbstractSurf4d::getAreaSize ( U3dPoint4d &  min, U3dPoint4d &  max  )

virtual

Return current 4D area size. Return 0 0 0 0 and 0 0 0 0 if no points were added

int U3dSVRGMathAbstractSurf4d::getGridPoint	(	int	i,
		int	j,
		int	k,
		U3dPoint4d &	p
	)

Return point associated with grid. This function returns type of point: initial is 1, otherwise 0. If indexies are out of range this method will return boundary values. Nothing for point if object is empty (return -1)

int U3dSVRGMathAbstractSurf4d::getGridX1Size ( )

inline

Return number of X1-coordinate grid elements

int U3dSVRGMathAbstractSurf4d::getGridX2Size ( )

inline

Return number of X2-coordinate grid elements

int U3dSVRGMathAbstractSurf4d::getGridX3Size ( )

inline

Return number of X3-coordinate grid elements

double U3dSVRGMathAbstractSurf4d::getMinGridStep ( )

inline

Return minimal distance between points lines when they will be in different grid rows or cols

virtual bool U3dSVRGMathAbstractSurf4d::getPoint ( double  p, double  q, double  r, U3dPoint4d &  pnt  )

pure virtual

Get 4d point from interpolated surface based on current pseudoregular grid. Return true if interpolation was made. Should be reimplemented.

Implemented in U3dSVRGMathBspl3Surf4d.

void U3dSVRGMathAbstractSurf4d::push_ip ( U3dPoint4d *  point )

protected

Push initial point to array of initial points and to proper grid cell

void U3dSVRGMathAbstractSurf4d::setMinGridStep ( double  eps )

inline

Set minimal distance between points lines when they will be in different grid rows or cols
