// .NAME vtkGeoProjectionSource - A 2D geographic geometry source
|
|
//
|
|
// .SECTION Description
|
|
// vtkGeoProjectionSource is a vtkGeoSource suitable for use in vtkTerrain2D.
|
|
// This source uses the libproj4 library to produce geometry patches at
|
|
// multiple resolutions. Each patch covers a specific region in projected
|
|
// space.
