LineMesh 使用问题

我在使用LineMesh画圆时接口如何圆滑一些

var displayObject = mainPanel.GetChild("Line" + 1).asImage.displayObject;

        LineMesh line3 = displayObject.graphics.GetMeshFactory<LineMesh>();

        line3.lineWidth = 3;

        line3.roundEdge = true;



        GPathPoint[] gPathPoints = new GPathPoint[eegPowers.GetLength(0);



        for (int j = 0; j < 8; j++)

        {

            gPathPoints[j] = new GPathPoint(new Vector2(eegPowers[j, 6].x, eegPowers[j, 6].y));



        }

        gPathPoints[8] = new GPathPoint(new Vector2(eegPowers[0, 6].x, eegPowers[0, 6].y));



        line3.path.Create(gPathPoints);

        displayObject.graphics.SetMeshDirty();
