I made something wrong with callDecoration("getConvexHull") but I don't know what

HEllo,

 

I'm trying to use the code node.callDecoration("getConvexHull")  to get the Convex hull of an element . I got the coordinates points but the Code callDecoration("getConvexHull")  change 'something' in the scene and then Cura Crash .

 

Any Idea or advise will be welcome ( @nallath, @fieldOfView ?)

 

    def addAutoSupportMesh(self) -> int:
        nb_Tab=0
        act_position = Vector
        
        for node in DepthFirstIterator(self._application.getController().getScene().getRoot()):
            if node.callDecoration("isSliceable"):
                Logger.log('d', "isSliceable : {}".format(node.getName()))
                node_stack=node.callDecoration("getStack")           
                if node_stack: 
                    type_infill_mesh = node_stack.getProperty("infill_mesh", "value")
                    type_cutting_mesh = node_stack.getProperty("cutting_mesh", "value")
                    type_support_mesh = node_stack.getProperty("support_mesh", "value")
                    type_anti_overhang_mesh = node_stack.getProperty("anti_overhang_mesh", "value") 
                    
                    if not type_infill_mesh and not type_support_mesh and not type_anti_overhang_mesh :
                    # and Selection.isSelected(node)
                        Logger.log('d', "Mesh : {}".format(node.getName()))
                        
                        hull_polygon = node.callDecoration("getConvexHull")
                        if not hull_polygon or hull_polygon.getPoints is None:
                            Logger.log("w", "Object {} cannot be calculated because it has no convex hull.".format(node.getName()))
                            continue

                        for point in hull_polygon.getPoints():
                            nb_Tab+=1 
                            Logger.log('d', 'X : ' + str(point[0]))
                            Logger.log('d', 'Y : ' + str(point[1]))
                            # self._createSupportMesh(node, act_position)
                               
        return nb_Tab

    Huh? the getConvexHull doesn't change anything in the scene... (or well, it sure as hell shouldn't :P)

     

    Also, what kind of crash do you get? A segfault?

    My apologies ... it works now the error must have come from something else.

     

    By cleaning the code to put it online, the error has disappeared! The problem must have been elsewhere.

     

    But thank you very much for this very fast support!

     

    [EDIT] Was a wrong definition of the Vector
