NAME

TrivTVRefineAtParams()  

SYNOPSIS

triv_lib/triv_ref.c:41

TrivTVStruct *TrivTVRefineAtParams(TrivTVStruct *TV,
                                   TrivTVDirType Dir,
                                   CagdBType Replace,
                                   CagdRType *t,
                                   int n)
 

DESCRIPTION

Given a trivariate, refines it at the given n knots as defined by the vector t. If Replace is TRUE, the values replace the current knot vector. Returns pointer to refined TV (Note a Bezier trivariate will be converted into a Bspline trivariate).  

PARAMETERS:

TV: Trivariate to refine according to t in direction Dir.

Dir: Direction of refinement. Either U or V or W.

Replace: If TRUE t is a knot vector exaclt in the length of the knot vector in direction Dir in TV and t simply replaces than knot vector. If FALSE, the knot vector in direction Dir in TV is refined by adding all the knots in t.

t: Knot vector to refine/replace the knot vector of TV in direction Dir.

n: Length of vector t.  

FUNCTION RETURN VALUE

TrivTVStruct *: The refined trivariate. Always a Bspline trivariate.
