float  tol,

)

Approximate the set of data points given a tolerance. uNoMultipleKNots and vNoMultipleKnots specify that no multiple knots is allowed in u and v parameteric direction respectively.

This approxmation is mainly for unwrapped surface. For wrapped curve, it may not behave well on the wrapped patch. However, you can improve its behaviour by duplicating the first row/col data points and put it at the end.

This is more powerful than convertNew. It always returns a NEW object, so free it when you're done with it. It may return a NURB surface or a Bezier surface depending on the type.

)

Perform data reduction by removing possible knots (and cvs) while maintaining the errors between all the data points and the actual points on the surface corresponding to the parm to be within the tolerance tol. If u/vNum is specified, the procedure will remove at least that number of knots in their corresponding parameters even when removing them may result in error > tol. The error(i,j) is the current error between data point corresponding to uParm(i) and vParm(j). The parameter lists have to be in non-decreasing order. The deleteGroup is used to gather unused cv geo points to be deleted. Output: update the error matrix, and reduce knots and cvs.

UT_BitArray remove_edges = 0 
)

Remove as many of the given edges of possible from this poly. If edge a is removed, bit a in the bit array is set to a & 1. returns 0 if successful, -1 if the poly becomes degenerate, and -2 if the poly should be removed.

int GU_PrimNURBSurf::removeKnot ( int  uDir,
int  knotIdx,
int  mult = 0,
float  tol = 1e-4F,
GA_PointGroup deleteGroup = 0,
int  uniqueInteriorCvs = 0 
)

Remove the interior knot at knotIdx once if possible, where mult is the multiplicity of the knot, and U/V[knotIdx] != U/V[knotIdx+1]. If multiplicity mult is not given, the procedure will compute it. The tol specifies the tolerance of distance between the knot removable position and its actual position. To force knot removal, set tol = -1.0F. The deleteGroup is used to gather unused cv geo points to be deleted. (It is more efficient to delete points in a group.) The uniqueInteriorCvs flag indicates whether the interior cvs need to be uniqued before removing knots. This is because during the process of knot removal, interior cvs may changed and/or got removed. Output: 1 if the knot got removed, else 0.
