示例1: iter

{
const int nPosts = 5;
const double radius = 0.5;
const double height = 5.0;
// Get a list of currently selected objects
MSelectionList selection;
MGlobal::getActiveSelectionList( selection );

MFnNurbsCurve curveFn;
double heightRatio = height / radius;
// Iterate over the nurbs curves
MItSelectionList iter( selection, MFn::kNurbsCurve );
for ( ; !iter.isDone(); iter.next() )
{
// Get the curve and attach it to the function set
iter.getDagPath( dagPath );
curveFn.setObject( dagPath );
// Get the domain of the curve, i.e. its start and end parametric values
double tStart, tEnd;
curveFn.getKnotDomain( tStart, tEnd );
