    How to create a filling of custom colour for convex hull with points from model ?
    I know how to draw convex hull:
    example code is below:

    Repeater {
              model: (page_algo.hmodel.count > 1)?page_algo.hmodel.count - 1:0
              Shape {
                  anchors.fill: parent
                  visible: cvxReady
                  ShapePath {
                     id: shapep
                     strokeWidth: 4
                     strokeColor: 'red'
                     fillColor: "white"
                     //capStyle: ShapePath.RoundCap
                     //joinStyle: ShapePath.RoundJoin
                     //fillRule: ShapePath.WindingFill
                     startX: page_algo.cvxReady? page_algo.hmodel.get(index).x: 0;
                     startY: page_algo.cvxReady? page_algo.hmodel.get(index).y: 0;
                      PathLine {
                          property int mcnt: page_algo.hmodel.count
                          x: page_algo.cvxReady? page_algo.hmodel.get((index + 1)%mcnt).x: 10
                          y: page_algo.cvxReady? page_algo.hmodel.get((index + 1)%mcnt).y: 0;
                      }
                  }
              }
          }

      Probles is solved.

      Shape {
                anchors.fill: parent
                visible: cvxReady
                ShapePath {
                    id: myPath
                    fillColor: "white"
                    strokeColor: "red"
                    capStyle: ShapePath.RoundCap
                    joinStyle: ShapePath.RoundJoin
                    strokeWidth: 3
                    strokeStyle: ShapePath.SolidLine
                    startX: page_algo.cvxReady? page_algo.hmodel.get(0).x: 0;
                    startY: page_algo.cvxReady? page_algo.hmodel.get(0).y: 0;
                }
            }
            Instantiator {
                model: page_algo.hmodel
                onObjectAdded: myPath.pathElements.push(object)
                PathLine {
                    x: model.mcoord.x
                    y: model.mcoord.y
                }
            }
