Hi,
I'm trying to use the calcVertexNormals function in order
to regenerate my surface normals. I first try to share all
possible vertices, then I run calcVertexNormals on the
geometry node (see the "calc" method below). The problem is
that not all normals are updated after a first run. If I
recall the "calc" method a second time, all normals are
finally updated. I can't see what the problem is...
Anything wrong in the code below?
Regards,
Toni
Action::ResultE
CalcNormals::createShareTraverse(NodePtr& curNode)
{
if ((curNode==NullFC)) return Action::Continue;
GeometryPtr geo = GeometryPtr::dcast(curNode->getCore());
if( geo != NullFC )
createSharedIndex(geo);
return Action::Continue;
}
Action::ResultE
CalcNormals::calcNormalsTraverse(NodePtr& curNode)
{
if ((curNode==NullFC)) return Action::Continue;
GeometryPtr geo = GeometryPtr::dcast(curNode->getCore());
if( geo != NullFC )
calcVertexNormals(geo, deg2rad(m_fCreaseAngle));
return Action::Continue;
}
bool
CalcNormals::calc( std::vector <osg::NodePtr> &nodeList )
{
for(unsigned int i=0;i<nodeList.size();++i)
{
traverse(nodeList[i],
osgTypedMethodFunctor1ObjPtrCPtrRef <Action::ResultE,
CalcNormals,
NodePtr>(this, CalcNormals::createShareTraverse));
}
for(unsigned int i=0;i<nodeList.size();++i)
{
traverse(nodeList[i],
osgTypedMethodFunctor1ObjPtrCPtrRef <Action::ResultE,
CalcNormals,
NodePtr>(this, CalcNormals::calcNormalsTraverse));
}
return true;
}
