Hello Mark,

At this point the surface series cannot display such amounts of data at interactive speeds. The only possible solution is to decrease the number of data points through some sort of data resampling.

We are planning some significant optimizations of the surface charts for the next version of the control, so hopefully they will be able to meet your requirements soon.

I'm dealing with the comparison of two large x, y, z data sets (potentially 1,000,000 points measured on each side of a two-sided surface).  I love the look of the mesh surface plot.  However, I need live interaction with the 3d plot (rotation, elevation) via the mouse. 

I've modified the mesh surface example http://examplesaspnetchart.nevron.com/Frames/NExampleFrame.aspx?ExampleUrl=Examples/ChartGallery/MeshSurface/NMeshIntersectedUC.ascx  to adjust elevation and rotation based on mouse dragging and it works fine (updating the graphic in real time as I drag the mouse) - however it only plots 20x20 points.  If I increase the example to only 200x200 (not even close to my needs), the plot takes almost 5 seconds to paint on my Windows 7/64 quad core machine.  This is far from "real time interaction".

So here's the question...

Is there some "fast" way to interact with large 3D surfaces in terms of rotation and elevation?  The redraw time is killing me.

Thanks,
