本文主要是基于数值着色与等高线特征,用数值绘制3D等高线网格图。以下是如何利用LightningChart绘制几何管道图并显示数据,以及提供相应的源代码。

此图是结果图例,显示温度冷热程度及数据

 

 

以下是绘制此图的源代码

 

LightningChartUltimate _chart = new LightningChartUltimate();

 

            _chart.BeginUpdate();

 

           

 

            //Create Surface mesh

 

            _mesh = new SurfaceMeshSeries3D(v, Axis3DBinding.Primary, Axis3DBinding.Primary, Axis3DBinding.Primary);

 

 

 

            //CONTOURS

 

            _mesh.ContourLineType = ContourLineType3D.ColorLineByValue;

 

            _mesh.ContourLineWidth = 1.5;

 

 

 

            //WIREFRAME           

 

            _mesh.WireframeType = SurfaceWireframeType.Wireframe;

 

            _mesh.WireframeLineStyle.Width = 3;

 

            _mesh.WireframeLineStyle.Color = Color.FromArgb(20, Color.Black);

 

            _mesh.WireframeOffset.SetValues(0, 0, 0);

 

           

 

            //FILL

 

            _mesh.ColorSaturation = 80;

 

            _mesh.Fill = SurfaceFillStyle.PalettedByValue;        

 

           

 

            //Discontinuity is caused by surface mesh…end meeting each other, and data is not fluently continous over that.

 

 

 

InitializePalette();

 

 

 

            double[,] x = null;

 

            double[,] y = null;

 

            double[,] z = null;

 

            double[,] values = null;

 

 

 

            CreateGeometryPipe(out x, out y, out z);

 

 

 

            CreateValuesWaterDrops(out values);

 

 

 

            UpdateMesh(x, y, z, values);

 

 

 

            v.SurfaceMeshSeries3D.Add(_mesh);

 

           

 

           

 

            v.YAxisPrimary3D.Units.Text = “°C”;

 

 

 

            _chart.EndUpdate();

 

 

 

总结

 

等高线地形图可综合应用于判断通视情况,水系水文特征,气候特征,地形状况与区位的选择(线、面 )。此3D几何图是用来判断气候特征的,非常直观。
