NAME

SymbPiecewiseRuledSrfApprox()  

SYNOPSIS

symb_lib/prisa.c:122

CagdSrfStruct *SymbPiecewiseRuledSrfApprox(CagdSrfStruct *Srf,
                                           CagdBType ConsistentDir,
                                           CagdRType Epsilon,
                                           CagdSrfDirType Dir)
 

DESCRIPTION

Constructs a piecewise ruled surface approximation to the given surface, Srf, in the given direction, Dir, that is close to the surface to within Epsilon. If ConsitentDir then ruled surface parametrization is set to be the same as original surface Srf. Otherwise, ruling dir is always CAGD_CONST_V_DIR. Surface is assumed to have point types E3 or P3 only.  

PARAMETERS:

Srf: To approximate using piecewise ruled surfaces.

ConsistentDir: Do we want parametrization to be the same as Srf?

Epsilon: Accuracy of piecewise ruled surface approximation.

Dir: Direction of piecewise ruled surface approximation. Either U or V.  

FUNCTION RETURN VALUE

CagdSrfStruct *: A list of ruled surfaces approximating Srf to within Epsilon in direction Dir.
