Detailed Description
generate texture coordinates by mapping points to cylinder
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.

| static int vtkTextureMapToCylinder::IsTypeOf | ( | const char * | name | ) | [static] |
Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

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.

| static vtkTextureMapToCylinder* vtkTextureMapToCylinder::New | ( | ) | [static] |
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.

This is called within ProcessRequest when a request asks the algorithm to do its work. This is the method you should override to do whatever the algorithm is designed to do. This happens during the fourth pass in the pipeline execution process.
