SurfaceMeshSeries3D don't support "InsertRowBackAndScroll"?

[bongsama]

SurfaceGridSeries3D Class is support function named "InsertRowBackAndScroll".

As you know, this function(InsertRowBackAndScroll) is optimized to real time data rendering.

So, I have to know how to use this function in SurfaceMeshSeries3D Class..(Not SurfaceGridSeries3D)

I find a function named "InsertRowBack" instead of "InsertRowBackAndScroll" but, I don't know hot to use it.

Please help me how to use this function(InsertRowBack & InsertRowBackAndScroll is support in SurfaceMeshSeries3D Class?)

I'll waiting for your reply.

Thanks

No wonder you are wondering especially how to use InsertRowBack. There's problem in that method. It truncated the data to be copied, if SizeZ < SizeX. It's been fixed now and waiting for next maintenance release. My apologies for that.

For SurfaceMeshSeries3D, you might as well use data shifting in a loop. InsertColumnBack and InsertRowBack shifts the data one column earlier or one row earlier, and inserts one column back or one row in the back.

Consider you have a surface mesh of size 100x40.

Code: Select all

int m_iRow = 0;
int RowLength = 100; 

//Initialize chart
chart.BeginUpdate();

            chart.ActiveView = Arction.WPF.LightningChartUltimate.ActiveView.View3D;

            SurfaceMeshSeries3D mesh = new SurfaceMeshSeries3D(chart.View3D, Arction.WPF.LightningChartUltimate.Axis3DBinding.Primary, Arction.WPF.LightningChartUltimate.Axis3DBinding.Primary, Arction.WPF.LightningChartUltimate.Axis3DBinding.Primary); 
            chart.View3D.SurfaceMeshSeries3D.Add(mesh);

            int iRowCount = 40;
            int iColumnCount = RowLength;

            SurfacePoint[,] points = new SurfacePoint[iColumnCount, iRowCount];
            Random rand = new Random(); 

            for (int iCol = 0; iCol < iColumnCount; iCol++)
            {
                for (int iRow = 0; iRow < iRowCount; iRow++)
                {
                    points[iCol, iRow].X = iCol;
                    points[iCol, iRow].Z = iRow;
                    points[iCol, iRow].Y = 10; // rand.NextDouble() * 100.0; 

                    
                }
            }

            m_iRow = iRowCount; 

            mesh.Data = points;

            chart.MouseDoubleClick += new MouseButtonEventHandler(chart_MouseDoubleClick);

            chart.EndUpdate(); 

Code: Select all

void chart_MouseDoubleClick(object sender, MouseButtonEventArgs e)
        {

            chart.BeginUpdate();

            //Add one row of data in the back 

            SurfacePoint[] newRowData = new SurfacePoint[RowLength]; 
            for(int iCol = 0; iCol < RowLength; iCol++)
            {
                newRowData[iCol].X = iCol; 
                newRowData[iCol].Z = m_iRow; 
                newRowData[iCol].Y = 50; 
            }

            m_iRow++; 

            int iRowCount = chart.View3D.SurfaceMeshSeries3D[0].SizeZ;
            SurfacePoint[,] data = chart.View3D.SurfaceMeshSeries3D[0].Data; 
            //Move old data 
            for (int iRow = 0; iRow < iRowCount - 1; iRow++)
            {
                for (int iCol = 0; iCol < RowLength; iCol++)
                {
                    data[iCol, iRow] = data[iCol, iRow + 1];
                }
            }

            //Copy new data in the back 
            for (int iCol = 0; iCol < RowLength; iCol++)
            {
                data[iCol, iRowCount - 1] = newRowData[iCol];
            }
            chart.View3D.SurfaceMeshSeries3D[0].InvalidateData(); 

            chart.EndUpdate(); 
        }

um..

What's this meaning that ..

int iRowCount = chart.View3D.SurfaceMeshSeries3D[0].SizeZ;
SurfacePoint[,] data = chart.View3D.SurfaceMeshSeries3D[0].Data;

array index?

SurfaceMeshSeries3D is not array..

[ArctionPasi]

View3D.SurfaceMeshSeries3D is collection, a list.

After creating a SurfaceMeshSeries3D (mesh) object and adding it into the collection by chart.View3D.SurfaceMeshSeries3D.Add(mesh), it becomes the first item in the View3D.SurfaceMeshSeries3D collection. So [0] is a list index, to access the first mesh series.
