vtkGlobeSource Class Reference
#include <vtkGlobeSource.h>
Detailed Description
Sphere patch with Lat/Long scalar array.vtkGlobeSource will generate any "rectangular" patch of the globe given its Longitude-Latitude extent. It adds two point scalar arrays Longitude and Latitude to the output. These arrays can be transformed to generate texture coordinates for any texture map. This source is imperfect near the poles as implmented. It should really reduce the longitude resolution as the triangles become slivers.

| virtual const char* vtkGlobeSource::GetClassName | ( | ) | [virtual] |
Reimplemented from vtkPolyDataAlgorithm.
| static int vtkGlobeSource::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 vtkTypeRevisionMacro found in vtkSetGet.h.

| virtual int vtkGlobeSource::IsA | ( | const char * | name | ) | [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.

| void vtkGlobeSource::PrintSelf | ( | ostream & | os, | |
| vtkIndent | indent | |||
| ) | [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.

| virtual void vtkGlobeSource::SetQuadrilateralTessellation | ( | int | ) | [virtual] |
Cause the sphere to be tessellated with edges along the latitude and longitude lines. If off, triangles are generated at non-polar regions, which results in edges that are not parallel to latitude and longitude lines. If on, quadrilaterals are generated everywhere except at the poles. This can be useful for generating a wireframe sphere with natural latitude and longitude lines.
