The Cylindroid 3D chart demo shows how to use CylindroidDataSeries3D and the FreeSurfaceRenderableSeries3D to render 3D cylindroid.

FreeSurfaceRenderableSeries3D allows you to create all kinds of shapes, including Sphere, Cylinder, Disc and free-form mesh shapes, and overlay heightmap, colormap (palette) and contours. Take a look at other examples of shapes in this section: simple polar mesh, simple ellipsoid chart, closed mesh chart, and a realtime ellipsoid mesh chart example.

Palette Mode drop-down menu demonstrates different modes of the data representation: Radial, Axial, Polar and Azimuthal.
