vtkGlobeSource

Section: Visualization Toolkit Geo Vis Classes

Usage

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.
