IsoSurface Issue with .net6

[sihmon]

Visual Studio 2022, dotnet core6
Steema.TeeChart.NET(4.2022.7.14)

I'm making a chart with dotnet core 6.0.
In the old version of tchart,
I Drew IsoSurface well in rainbow style.
But now it's not painted in a rainbow style.
Is there anything I need to check?


==========================

this.isoSurface1 = new Steema.TeeChart.Styles.IsoSurface();
this.tChart1.Series.Add(this.isoSurface1);
this.isoSurface1.PaletteStyle = Steema.TeeChart.Styles.PaletteStyles.Rainbow;
this.isoSurface1.PaletteSteps = 20;
this.isoSurface1.WireFrame = false;
this.isoSurface1.DotFrame = false;
this.isoSurface1.PaletteSteps++;
this.isoSurface1.UseColorRange = false;
this.isoSurface1.UsePalette = true;
this.isoSurface1.PaletteSteps--;

Hello,

But now it's not painted in a rainbow style.
Is there anything I need to check?

This seems to work okay with the latest NuGet and the following code:

Code: Select all

    public Form1()
    {
      InitializeComponent();
      InitializeChart();
    }

    private void InitializeChart()
    {
      var iso = new IsoSurface(tChart1.Chart);
      iso.FillSampleValues();
      tChart1.Aspect.View3D = true;
      tChart1.Aspect.Chart3DPercent = 100;
      tChart1.Aspect.Zoom = 60;
      tChart1.Aspect.Orthogonal = false;
      tChart1.Aspect.Rotation = 300;
      tChart1.Aspect.Elevation = 300;
      tChart1.Aspect.Perspective = 100;
      iso.PaletteStyle = Steema.TeeChart.Styles.PaletteStyles.Rainbow;


      tChart1.Tools.Add(typeof(Rotate));

      tChart1.Header.Text += $" version {Utils.Version}";
    }

In .NET Framework 4.0 Windows Forms I get this:

and in .net6.0 Windows Forms I get this:

The IsoSurface.WireFrame shape has changed.
Previously, I used wireframe set to true.
However, now I Have to set it to false and use it.
before, there was only one color space per wire.
Now several colors are mixed in one wire.
Can I draw with one color on one wire?

Code: Select all

isoSurface1.Brush.Visible= false;
isoSurface1.WireFrame = false;
isoSurface1.DotFrame = false;

The IsoSurface.WireFrame shape has changed.
Previously, I used wireframe set to true.

We have been able to reproduce this error with WireFrame and have added it to our issue tracker with id=2560. Apologies for the inconvenience caused by this issue; we will look into it as soon as possible.

Our conversation went wrong.

4.0.2009.62332
In version 4.0.2009.62332,
a rainbow color is completed with one color for each wire.


4.2022.9.26 dotnet6 core
In version 4.2022.9.26,
a rainbow color is completed with multiple colors for each wire.




4.2022.10.11 dotnet6 core
In the latest updated version 4.2022.10.11, all wires are the same color. Black



Like version 4.0.2009.62332, I want the rainbow to be drawn with a color for each wire

Code: Select all

   
   isoSurface1.Brush.Transparency = 0;
            isoSurface1.BandPen.Visible = true;
            isoSurface1.FillSampleValues();
            isoSurface1.PaletteSteps = 25;
            isoSurface1.PaletteStyle = Steema.TeeChart.Styles.PaletteStyles.Rainbow;

            tChart1.Aspect.View3D = true;
            tChart1.Zoom.Direction = Steema.TeeChart.ZoomDirections.None;
            rotate1 = new Rotate();
            rotate1.Rotating += Rotate1_Rotating;
            this.tChart1.Tools.Add(this.rotate1);


                isoSurface1.WireFrame = false;
                isoSurface1.DotFrame = false;
                isoSurface1.Brush.Visible = false;

Hello,

Okay, I've run your code, specifically, I've run this code against version 4.0.2009.62332:

Code: Select all

    public Form1()
    {
      InitializeComponent();
      InitializeChart();
    }

    private void InitializeChart()
    {
      var iso = new IsoSurface(tChart1.Chart);
      iso.FillSampleValues();

      tChart1.Aspect.View3D = true;
      tChart1.Aspect.Chart3DPercent = 100;
      tChart1.Aspect.Zoom = 60;
      tChart1.Aspect.Orthogonal = false;
      tChart1.Aspect.Rotation = 300;
      tChart1.Aspect.Elevation = 300;
      tChart1.Aspect.Perspective = 100;


      iso.Brush.Transparency = 0;
      iso.BandPen.Visible = true;
      iso.FillSampleValues();
      iso.PaletteSteps = 25;
      iso.PaletteStyle = Steema.TeeChart.Styles.PaletteStyles.Rainbow;
      iso.WireFrame = false;
      iso.DotFrame = false;
      iso.Brush.Visible = false;



      tChart1.Tools.Add(typeof(Rotate));

      //tChart1.Header.Text += $" version {Utils.Version}";

      var assembly = Assembly.GetAssembly(typeof(TChart));
      var fvi = System.Diagnostics.FileVersionInfo.GetVersionInfo(assembly.Location);

      tChart1.Header.Text += $" version {fvi.FileVersion}";
    }

That code gives me:

The lines here are black—could you please modify this code so that I can reproduce what you want in version 4.0.2009.62332? Once I can reproduce it in this old version I can then have a look to see what the problem is in the present one.

[sihmon]

please, Try running this code in version 4.0.2009.62332
You can see the difference.

Code: Select all

public Form1()
    {
      InitializeComponent();
      InitializeChart();
    }

    private void InitializeChart()
    {
      var iso = new IsoSurface(tChart1.Chart);
      iso.FillSampleValues();

      tChart1.Aspect.View3D = true;
      tChart1.Aspect.Chart3DPercent = 100;
      tChart1.Aspect.Zoom = 60;
      tChart1.Aspect.Orthogonal = false;
      tChart1.Aspect.Rotation = 300;
      tChart1.Aspect.Elevation = 300;
      tChart1.Aspect.Perspective = 100;


      iso.Brush.Transparency = 0;
      iso.BandPen.Visible = true;
      iso.PaletteSteps = 25;
      iso.PaletteStyle = Steema.TeeChart.Styles.PaletteStyles.Rainbow;
      iso.DotFrame = false;
      iso.Brush.Visible = false;
      iso.WireFrame = true;


      tChart1.Tools.Add(typeof(Rotate));

      //tChart1.Header.Text += $" version {Utils.Version}";

      var assembly = Assembly.GetAssembly(typeof(TChart));
      var fvi = System.Diagnostics.FileVersionInfo.GetVersionInfo(assembly.Location);

      tChart1.Header.Text += $" version {fvi.FileVersion}";
    }

Thank you, yes, now I can see the difference, and I have added this issue to our issue tracker with id=2562. We will look into it as soon as we can.

Hello,

just to let you know that this is now fixed in the latest NuGet package.

Wow, thank you so much.
It's perfect.
