I need to call my deformer everytime that a particular object is modified (the points position is changed). To solve this I save all the object's points and I verify in the checkdirty function if some points are changed from last time.
There is a more cleaver (and more quick) method to do this?

Thank's
Lorenzo

Solved! Find the simple solution in an old post (I apologize in order to haven't seen it before)

ULONG dirty_bit = spline->GetDirty(DIRTY_DATA|DIRTY_MATRIX);
if(dirty_bit!=s_dirty)
{
    s_dirty = dirty_bit;
    op->SetDirty(DIRTY_MATRIX);
    /*Or DIRTY_DATA depending on when your deformer updates*/
}
