Hello,
I checked the source code of OCCVertex.h and wondering what the second while
loop doing and
what is special about Seam edges in this code ?
Thanks.

SPoint2 OCCVertex::reparamOnFace(const GFace *gf, int dir) const
{
std::list<GEdge*>::const_iterator it = l_edges.begin();
while(it != l_edges.end()){
std::list<GEdge*> l = gf->edges();
if(std::find(l.begin(), l.end(), *it) != l.end()){
if((*it)->isSeam(gf)){
const TopoDS_Face *s = (TopoDS_Face*)gf->getNativePtr();
const TopoDS_Edge *c = (TopoDS_Edge*)(*it)->getNativePtr();
double s1,s0;
Handle(Geom2d_Curve) curve2d = BRep_Tool::CurveOnSurface(*c, *s, s0,
s1);
if((*it)->getBeginVertex() == this)
return (*it)->reparamOnFace(gf, s0, dir);
else if((*it)->getEndVertex() == this)
return (*it)->reparamOnFace(gf, s1, dir);
}
}
++it;
}
it = l_edges.begin();
while(it != l_edges.end()){
std::list<GEdge*> l = gf->edges();
if(std::find(l.begin(), l.end(), *it) != l.end()){
const TopoDS_Face *s = (TopoDS_Face*)gf->getNativePtr();
const TopoDS_Edge *c = (TopoDS_Edge*)(*it)->getNativePtr();
double s1,s0;
Handle(Geom2d_Curve) curve2d = BRep_Tool::CurveOnSurface(*c, *s, s0,
s1);
if((*it)->getBeginVertex() == this)
return (*it)->reparamOnFace(gf, s0, dir);
else if((*it)->getEndVertex() == this)
return (*it)->reparamOnFace(gf, s1, dir);
}
++it;
}
