NAME
BspSrfMeshNormals()
SYNOPSIS
cagd_lib/sbsp_aux.c:953
CagdVecStruct *BspSrfMeshNormals(CagdSrfStruct *Srf,
int UFineNess,
int VFineNess)
DESCRIPTION
Evaluates the unit normals of a surface at a mesh defined by subdividing
the parametric space into a grid of size UFineNess by VFineNess.
The normals are saved in a linear CagdVecStruct vector which is
allocated dynamically. Data is saved u inc. first.
This routine is much faster than evaluating normal for each point,
individually.
PARAMETERS:
Srf: To compute normals on a grid of its parametric domain.
UFineNess: U Fineness of imposed grid on Srf's parametric domain.
VFineNess: V Fineness of imposed grid on Srf's parametric domain.
FUNCTION RETURN VALUE
CagdVecStruct *: An vector of unit normals (u increments first).
