c# - iLNumerics isn't displaying my 3d plot - the plot remains 2d -

the code this:

        //we need render locations.         ilarray<float> ourpositions = oursimulator.getstars();          var scene = new ilscene();         var plotcube = scene.add(new ilplotcube(twodmode: false));          var ourposbuffer = new ilpoints();         ourposbuffer.positions = ourpositions;          plotcube.add(ourposbuffer);         plotcube.fieldofview = 120;         plotcube.lookat = new vector3(0, 0, 0);          ilstarchart.scene.configure(); 

now, earlier version of code (in different solution) still uses 3.3.2, ,

        var plotcube = scene.add(new ilplotcube(null, false) ) 

i've tried both on 3.3.3 version, , neither displays 3d plot. instead, it's 2d grid. doing wrong here?

(the points are:

        <single> [3,4]         -32.00000 37.00000 36.00000 38.00000          54.00000 107.00000 106.00000 130.00000         -81.00000 -16.00000 -124.00000 -226.00000   

)

edited: missing ) on 3.3.2 example

edited: reduced of non critical code out of example.

the expected result have 3d plot x,y , z axis. i'm getting 2d plot. no z axis. i've verified points (the tostring)

a sample run provides this: https://www.dropbox.com/s/imiw8tbe0lh8q9x/2dplot.png

this rough example of used, need add "ilsurface" plotcube

        //replace , make sure added in order         single[] zs = [all zs]         single[] xs = [all xs]         single[] ys = [all ys]                     //create array of points               //something below         ilarray<float> points = ilmath.zeros<float>(xs.length/s, s, 3);         points[":;:;0"] = zs;         points[":;:;1"] = xs;         points[":;:;2"] = ys;                      // construct new plotcube , plot points         scene = new ilscene();         cube = new ilplotcube(twodmode: false);         surface = new ilsurface(points, colormap: colormaps.jet);           //set scene properties         scene.add(cube);          //display cube in scene         ilpanel1.scene = scene;
