Multiple colors points in 3D openGL suface.

I am plotting two 3D openGL surfaces. One of them (red) is top border. Enother one is a function. If some point of this surface is above red border it should be orange, if not - blue. I've made a simple application like that:

But the result was surprising:

Second surface is all blue. So what should I do?

By the way I've discovered than surface is drawing (also rotating, elevating, etc) faster than triSurface with the same data. Am I right?
Do you know what type of surface will draw faster: solid or dot?

Thank you.

Hi bairog,

Could you please send us a simple example project we can run "as-is" to reproduce the problem here and let us know the TeeChart version you are using?

You can either post your files at news://www.steema.net/steema.public.attachments newsgroup or at our upload page.

Thanks in advance.

Done. By the way if in this project I use triSurface instead of surface it works fine. But in runs slower and triSurface has the problem discribed in this topic so I decided to use surface.

I use TeeChart v2 Build 2.0.2652.22325
By the way on that page the latest version is displayed as "Latest Binary version: 30th January 2007 Framework 1.1 Build 2.0.2586.24038, Framework 2.0 Build 2.0.2586.24039"

And you didn't answered to my second question

Please tell me which drawing mode is the fastest (it is critical for my project).

Thank you.

Hi bairog,

Thanks for the example.

To solve your problem you can set UsePalette to true:

Code: Select all

   private void MGnazemle3D_Load(object sender, EventArgs e)
        {
            teeOpenGL1.Light0.Visible = false;

						surface2.UsePalette = true;
            for (double x = 0; x <= 10; x +=0.5) 
            {
                for (double z = 0; z <= 10; z += 0.5)
                {
										surface1.Add(x, 10, z);
										if (x + z <= 10)
											surface2.Add(x, x + z, z, Color.Blue);
										else
											surface2.Add(x, x + z, z, Color.Orange);
                }
            }
        }

By the way I've discovered than surface is drawing (also rotating, elevating, etc) faster than triSurface with the same data. Am I right?

Yes, Surface series is much faster than TriSurface series.

Do you know what type of surface will draw faster: solid or dot?

Wireframed surfaces are the fastest, then comes dotted surface and finally solid surfaces.

BTW: We will try to find a solution to the TriSurface issue you pointed.
