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).

virtual const char* vtkTextureMapToSphere::GetClassName  )  [virtual]
 

Reimplemented from vtkDataSetToDataSetFilter.

int vtkTextureMapToSphere::IsTypeOf const char *  type  )  [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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkDataSetToDataSetFilter.

virtual int vtkTextureMapToSphere::IsA const char *  type  )  [virtual]
 

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkDataSetToDataSetFilter.

[virtual]
 

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.

Reimplemented from vtkDataSetToDataSetFilter.
