NAME

TrivSrfFromTV()

SYNOPSIS

triv_lib/triveval.c:202

CagdSrfStruct *TrivSrfFromTV(TrivTVStruct *TV,
                             CagdRType t,
                             TrivTVDirType Dir)

DESCRIPTION

Extract an isoparametric surface out of the given tensor product trivariate. Operations should favor the CONST_W_DIR, in which the extraction is somewhat faster, if it is possible.

PARAMETERS:

TV: To extract an isoparametric surface from at parameter value t in direction Dir.

t: Parameter value at which to extract the isosurface.

Dir: Direction of isosurface extraction. Either U or V or W.

FUNCTION RETURN VALUE

CagdSrfStruct *: A bivariate surface which is an isosurface of TV.
