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).
-
Warning:
-
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 use the class vtkTransformTexture to linearly scale and shift the origin of the texture coordinates.

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Create object with cylinder axis parallel to z-axis (points (0,0,-0.5) and (0,0,0.5)). The PreventSeam ivar is set to true. The cylinder is automatically generated.
