基于等高线算法绘制几何管道，并显示数据

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();

           

           //CreateSurface mesh

           _mesh = newSurfaceMeshSeries3D(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, anddata 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(点、线、面)。此3D几何图是用来判断气候特征的，非常直观。
