Hi Steema,

Is it possible to create continuous colored 3D surface in WPF? I mean not only solid colored surface rectangles, but with color gradient depending on height (see attachment). I'm able to do this in .NET form application by enabling openGl, but not having luck in WPF.
Thanks for every advice.

Hi zizou5,

I'm afraid not, this is an OpenGL specific functionality. What you can do is defining gradient sort of ColorRange as shown in the All Features\Welcome !\Chart styles\Extended\Contour\Palette and Color range or All Features\Welcome !\Chart styles\Extended\Surface\Wireframe and palette examples in the features demo, available at TeeChart's program group. As an alternative, you can create your custom color palette as in the example I made here.

ok, thank you for information and possible alternative tips. It would be great if this possibility appears in future teechart .NET versions

Can you show me some code which 'turns on' OpenGL and implements the continuously colored surface as shown above?

Steema.TeeChart.Drawing.GL.TeeOpenGL openGL = new Steema.TeeChart.Drawing.GL.TeeOpenGL(SurfaceChart.Chart);
openGL.Active = true;
openGL.ShadeQuality = true;

Has this answered the question for you?
