create a ellipsoidal-shaped button
<p>
<a class="el" href="a00457.html" title="create a ellipsoidal-shaped button">vtkEllipticalButtonSource</a> creates a ellipsoidal shaped button with texture coordinates suitable for application of a texture map. This provides a way to make nice looking 3D buttons. The buttons are represented as <a class="el" href="a01260.html" title="concrete dataset represents vertices, lines, polygons, and triangle strips">vtkPolyData</a> that includes texture coordinates and normals. The button lies in the x-y plane.<p>
To use this class you must define the major and minor axes lengths of an ellipsoid (expressed as width (x), height (y) and depth (z)). The button has a rectangular mesh region in the center with texture coordinates that range smoothly from (0,1). (This flat region is called the texture region.) The outer, curved portion of the button (called the shoulder) has texture coordinates set to a user specified value (by default (0,0). (This results in coloring the button curve the same color as the (s,t) location of the texture map.) The resolution in the radial direction, the texture region, and the shoulder region must also be set. The button can be moved by specifying an origin.<p>

Set/Get the radial ratio. This is the measure of the radius of the outer ellipsoid to the inner ellipsoid of the button. The outer ellipsoid is the boundary of the button defined by the height and width. The inner ellipsoid circumscribes the texture region. Larger RadialRatio's cause the button to be more rounded (and the texture region to be smaller); smaller ratios produce sharply curved shoulders with a larger texture region.
