Detailed Description

generate texture coordinates by mapping points to sphere

vtkTextureMapToSphere is a filter that generates 2D texture coordinates by mapping input dataset points onto a sphere. The sphere can either be user specified or generated automatically. (The sphere is generated automatically by computing the center (i.e., averaged coordinates) of the sphere.) Note that the generated texture coordinates range between (0,1). The s-coordinate lies in the angular direction around the z-axis, measured counter-clockwise from the x-axis. The t-coordinate lies in the angular direction measured down from the north pole towards the south pole.

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

The resulting texture coordinates will lie between (0,1), and the texture coordinates are determined with respect to the modeler's x-y-z coordinate system. Use the class vtkTransformTextureCoords to linearly scale and shift the origin of the texture coordinates (if necessary).

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.
