vtkTextureMapToCylinder - generate texture coordinates by mapping points to cylinder

Super Class: vtkDataSetToDataSetFilter

Description:

vtkTextureMapToCylinder is a filter that generates 2D texture coordinates by mapping input dataset points onto a cylinder. The cylinder can either be user specified or generated automatically. (The cylinder is generated automatically by computing the axis of the cylinder.) Note that the generated texture coordinates for the s-coordinate ranges from (0-1) (corresponding to angle of 0->360 around axis), while the mapping of the t-coordinate is controlled by the projection of points along the axis. To specify a cylinder manually, you must provide two points that define the axis of the cylinder. The length of the axis will affect the t-coordinates. A special ivar controls how the s-coordinate is generated. If PreventSeam is set to true, the s-texture varies from 0->1 and then 1->0 (corresponding to angles of 0->180 and 180->360).

Caveats:

Since the resulting texture s-coordinate will lie between (0,1), and the origin of the texture coordinates is not user-controllable, you may want to se the class vtkTransformTexture to linearly scale and shift the origin of the texture coordinates.
