[Closed] How to update mesh edge selection in SDK?

Jan 23, 2009 11:11 pm

hi there!.

I’m creating an edge selection tool plugin with the 3ds max sdk, the problem that i have is when i set the edge selection, it doesn’t update in viewports until i pan or rotate the view. I tryed redrawing viewports but it didn’t work.

this is the line:

targetPolyObj->mm.SetEdgeSel(edgeToSelect,true);

targetPolyObj is an instance from the polyObject class.

any thoughts?, thanks

Hi, not using SDK that had a similar issue while scripting.
You probably need to call the ‘update’ function

well… is not scripting actually (i’m programming a .dlx in visual C++ with the 3ds max sdk).

i have searched some update functions but haven’t found any yet (inside the MNMesh or polyObject class), maybe there’s one there but i don’t know which :(.

i have tried the LocalDataChanged function from the ePoly class but it didn’t success either :’(.

Hi Felix,
I guess you only missed to refresh viewports after setting the edge

// <void> customSelEdge <Poly poly> <Integer edgeIndex>
Value* customSelEdge_cf(Value** arg_list, int count) {
  check_arg_count(customSelEdge, 2, count);

  Object* obj = NULL;
  MNMesh* poly = NULL;
  int edgeIndex = 0;

  if (is_node(arg_list[0])) {
    obj = ((MAXNode*)arg_list[0])->to_node()->GetObjectRef();

    if (obj->ClassID() == EPOLYOBJ_CLASS_ID)
      poly = &((PolyObject*)obj)->GetMesh();
    else
      throw RuntimeError ("Poly operation on non-Poly ", obj->GetObjectName());
  }

  if ( is_integer_number(arg_list[1]) && (arg_list[1]->to_int() > 0) && (arg_list[1]->to_int() <= poly->nume) )
    edgeIndex = arg_list[1]->to_int() -1;
  else
    throw RuntimeError ("Edge index not integer or out of range for ", obj->GetObjectName());

  poly->SetEdgeSel(edgeIndex, TRUE);
  [B]MAXScript_interface->ForceCompleteRedraw();[/B]

  return &ok;
}

def_visible_primitive(customSelEdge, "customSelEdge");

Cheers
