SymbSrfFff()  

SYNOPSIS

symb_lib/curvatur.c:616

void SymbSrfSff(CagdSrfStruct *DuSrf,
                CagdSrfStruct *DvSrf,
                CagdSrfStruct **SffL11,
                CagdSrfStruct **SffL12,
                CagdSrfStruct **SffL22,
                CagdSrfStruct **SNormal)
 

DESCRIPTION

Computes coefficients of the first fundamental form of given surface Srf. These coefficients are using non normalized normal that is also returned.  

PARAMETERS:

DuSrf: First derivative of Srf with respect to U.

DvSrf: First derivative of Srf with respect to V.

SffL11: SFF L11 scalar field returned herein.

SffL12: SFF L12 scalar field returned herein.

SffL22: SFF L22 scalar field returned herein.

SNormal: Unnormalized normal vector field returned herein.
