Demonstrates the basics of the UniformGridDataSeries3D and SurfaceMeshRenderableSeries3D.

This versatile type allows rendering of 3D surfaces / terrain / grids / spectrogram and heatmaps which could be used for visualizing Topology data, Statistical analysis, Volatility Smiles etc…

The Surface Mesh colors and palette can be updated by supplying a MeshColorPalette, which wraps a LinearGradientBrush, or a Texture. The SurfaceMeshRenderableSeries3D allows various paletting options and rendering options, such as Wireframe, Solid Mesh, Solid Cells Height-map, Interpolated Height-map and plain texturing.
