Constructor & Destructor Documentation

U3dBspl3Surface4d::U3dBspl3Surface4d ( const U3dBspl3AbstractMatrix &  bm,
const U3dPoints4dAr &  points,
double  g_step 
)

Construct surface with provided interpolation points and for minimal grid step value. Base matrix defines approximation type.

Member Function Documentation

virtual void U3dBspl3Surface4d::approximate ( const U3dBspl3AbstractMatrix &  bm,
const U3dPoints4dAr &  points,
double  g_step 
)
virtual

Main approximation method. Requires base matrix, initial points and minimal regular grid step. Old initial points surface are deleting.

void U3dBspl3Surface4d::clear ( )
protected

Clear all data

bool U3dBspl3Surface4d::get_expanded_gp ( int  i,
int  j,
int  k,
U3dPoint4d &  point 
)
protected

Return point of expanded grid with boundary nodes. i = 0..m+3, j=0..n+3, k=0..k+3. Return true if ok.

void U3dBspl3Surface4d::getAreaSize ( U3dPoint4d &  min,
U3dPoint4d &  max 
)

Return current area size. Actually if approximation was made.

virtual bool U3dBspl3Surface4d::getPoint ( double  p,
double  q,
double  r,
U3dPoint4d &  point 
)
virtual

Get 4d point from provided pqr=[0..1]^3 parameters. Return true if interpolation was made.

U3dBspl3MatrixType U3dBspl3Surface4d::getType ( )

Return base spline surface type. If object is not ready return "Undefined".

bool U3dBspl3Surface4d::isInterpolated ( )
inline

Return true if interpolation was made
