ILNumerics Drawing a surface having (x,y,z) coordinates

I am really new in programming with C#. I have an Array of points in the following form

//An Array containing point coordinates:

double[,] graphData=new double[100,3]; //Each element of graph data contain coordinate of a point:

graphData[1;:]=(x1,y1,z1);

I wanna draw a surface using ILNumerics. I couldn't find any example for this case. Would you please help me?

The link posted in the accepted answer points to an outdated part of the ILNumerics documentation which is obsolete now. Up from version 3, surfaces utilize a new scene graph based rendering API.

Documentation: http://ilnumerics.net/surface-plots.html

However, the linke posted by Roy Dictus may help in explaining how to turn your data into matrix shaped data, suitable for surface rendering.

Basically, surfaces create a mesh based on the matrix shaped input data. It connects the incoming points according to their location in the input matrix. So instead of a list of points you have to provide:

  • a single matrix of Z values, if a regular grid of heights values is to be rendered only, or
  • same shaped matrices for Z, X and Y values for non-regular grids and parametric surfaces.
