Cross on Surface 3D

[inea]

Hello,

I 've question about cross(point) on surface 3D.

Is it possible to have a floatin cross or point on surface 3D (like in picture)?
What is a easy way to do it in TeeChart v6 or TeeChartV2010, but better it will be in v6.

Thank you for your answer.

Hello inea,

You can use SurfaceNereastTool you can find an example in TeeChart.Net demo project AllFeauters\Welcome !\Tools\Surface Nearest .

I hope will helps.

Thanks,

Hello Sandra,

Thank you for your quick answer at first.
I may use SurfaceNereastTool, if it possible to connect ColorGrid and Surface.
I have to implement ColorGrid, with floating cross(like in picture). And when I move this cross with mouse, cross on surface is move to.

i 've implemented ColorGrid with CursorTool. And by the way, how i get Z value from ColorGrid with CursorTool ?
Is it better way to implement ColorGrid with CursorTool or NereastPoint ? I have to be very precise #.000000

Thank you for your answer, and sorry for my english

Hello iena,

Sorry for the delay. I have made a simple code for you using SurfaceNearestTool and CursorTool. Please check if it works as you want:

Code: Select all

public Form1()
        {
            InitializeComponent();
            InitializeChart();
        }
        private Steema.TeeChart.Tools.CursorTool tool2;
        private Steema.TeeChart.Tools.SurfaceNearestTool tool3;
        private void InitializeChart()
        {
            tChart1.Aspect.Orthogonal = false;
            tChart1.Aspect.Chart3DPercent = 50;
            Steema.TeeChart.Styles.Surface Series1 = new Steema.TeeChart.Styles.Surface(tChart1.Chart);
            Steema.TeeChart.Styles.ColorGrid Series2 = new Steema.TeeChart.Styles.ColorGrid(tChart2.Chart);
            Series2.IrregularGrid = true;
            Series1.FillSampleValues();
            Series2.DataSource = Series1;
            tChart1.Tools.Add(new Steema.TeeChart.Tools.Rotate());

            tChart2.Aspect.View3D = false;
    
            tool2 = new Steema.TeeChart.Tools.CursorTool(tChart2.Chart);
            tool3= new Steema.TeeChart.Tools.SurfaceNearestTool(tChart1.Chart);
            tool3.Series = Series1;
            tool2.Series = Series2;
            tool2.FollowMouse = true;
            tool2.Pen.Color = Color.Red;
            tool2.Snap = true;
            tool2.Pen.Width = 2;
            tool3.Select += new Steema.TeeChart.Tools.SelectEventHandler(tool3_Select);
        }
      
        void tool3_Select(object sender, EventArgs e)
        {
            int index = (sender as Steema.TeeChart.Tools.SurfaceNearestTool).SelectedCell;
            CursorSynchronize(index, tool2);
        }

        private void CursorSynchronize(int index, Steema.TeeChart.Tools.CursorTool TOOL)
        {
            double ZValueColorGrid;
            Steema.TeeChart.Styles.ColorGrid colorGrid = (tChart2[0] as Steema.TeeChart.Styles.ColorGrid);
            if (index != -1)
            {
                ZValueColorGrid = colorGrid.ZValues[index];
                TOOL.XValue = colorGrid.XValues[index];
                TOOL.YValue = ZValueColorGrid;
                this.Text = index.ToString() + "," + "Value Z" + ZValueColorGrid.ToString();
            }
        }
        private void button2_Click(object sender, EventArgs e)
        {
            tChart1.ShowEditor();
        }

        private void button3_Click(object sender, EventArgs e)
        {
            tChart2.ShowEditor();
        }

I hope will helps.

Hello Sandra,
Thank you very much, for example and your's time. This sample is amazing.
Sorry, that my interpretation was't very good, but I need oposite functionality.
When I 'll move cursor on ColorGrid, SurfaceNearestTool change his position. SurfaceNearestTool have to be moved only by ColorGrid cursor.

Is this somehow possible?

Thank you for your answer.

Could you tell us if it code works as you want?

I hope will helps.

Hello Sandra,

Thank you very much for this example.
This example it works exactly as I want.

Almost perfect, becouse I have irregular surface and irregular colorGrid, and this example doesn't work right with irregular colorGrid and surface.
Also SurfaceNearestTool doesn't work correct if I have irregular surface. Is it a bug?

I have X and Z values from -100 to 100 on 10x10 surface.
Can I somehow add regular surface with 10000 points, and only 100 poits is visible on surface?

That is my sample DataSource:

Code: Select all

DataTable t1 = new DataTable();
            t1.Columns.Add("x");
            t1.Columns.Add("y");
            t1.Columns.Add("z");

            t1.Rows.Add(1, 3, 1);
            t1.Rows.Add(3, 2, 1);
            t1.Rows.Add(5, 3, 1);
            t1.Rows.Add(7, 3, 1);

            t1.Rows.Add(1, 3, 3);
            t1.Rows.Add(3, 2, 3);
            t1.Rows.Add(5, 3, 3);
            t1.Rows.Add(7, 3, 3);

            t1.Rows.Add(1, 3, 5);
            t1.Rows.Add(3, 2, 5);
            t1.Rows.Add(5, 3, 5);
            t1.Rows.Add(7, 3, 5);

            t1.Rows.Add(1, 3, 7);
            t1.Rows.Add(3, 2, 7);
            t1.Rows.Add(5, 3, 7);
            t1.Rows.Add(7, 3, 7);
           surface.DataSource = t1;

Thank you very much for your answer.

Hello Sandra,

Thank you very much for this example. This example work well.

But with my sample data, this example doesn't work.
Could you please try my sample Data?

Code: Select all

DataTable t1 = new DataTable();
            t1.Columns.Add("x");
            t1.Columns.Add("y");
            t1.Columns.Add("z");

            t1.Rows.Add(1, 3, 1);
            t1.Rows.Add(3, 2, 1);
            t1.Rows.Add(5, 3, 1);
            t1.Rows.Add(7, 3, 1);

            t1.Rows.Add(1, 3, 3);
            t1.Rows.Add(3, 2, 3);
            t1.Rows.Add(5, 3, 3);
            t1.Rows.Add(7, 3, 3);

            t1.Rows.Add(1, 3, 5);
            t1.Rows.Add(3, 2, 5);
            t1.Rows.Add(5, 3, 5);
            t1.Rows.Add(7, 3, 5);

            t1.Rows.Add(1, 3, 7);
            t1.Rows.Add(3, 2, 7);
            t1.Rows.Add(5, 3, 7);
            t1.Rows.Add(7, 3, 7);
           surface.DataSource = t1;

Thank you very much for your answer.
