NAME

SymbSrfSubdivOffset()  

SYNOPSIS

symb_lib/offset.c:355

CagdSrfStruct *SymbSrfSubdivOffset(CagdSrfStruct *Srf,
                                   CagdRType OffsetDist,
                                   CagdRType Tolerance)
 

DESCRIPTION

Given a surface and an offset amount OffsetDist, returns an approximation to the offset surface by offseting the control mesh in the normal direction. If resulting offset is not satisfying the required tolerance the surface is subdivided and the algorithm recurses on both parts.  

PARAMETERS:

Srf: To approximate its offset surface with distance OffsetDist.

OffsetDist: Amount of offset. Negative denotes other offset direction.

Tolerance: Accuracy control.  

FUNCTION RETURN VALUE

CagdSrfStruct *: An approximation to the offset surface, to within Tolerance.
