Detailed Description
A 2D terrain model for the globe.
vtkGeoTerrain2D contains a multi-resolution tree of geometry representing the globe. It uses a vtkGeoSource subclass to generate the terrain, such as vtkGeoProjectionSource. This source must be set before using the terrain in a vtkGeoView2D. The terrain also contains an AddActors() method which updates the set of actors representing the globe given the current camera position.

Member Function Documentation
| static vtkGeoTerrain2D* vtkGeoTerrain2D::New | ( | ) | [static] |
Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
Reimplemented from vtkGeoTerrain.
| static int vtkGeoTerrain2D::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 vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkGeoTerrain.
| virtual int vtkGeoTerrain2D::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 vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkGeoTerrain.
| static vtkGeoTerrain2D* vtkGeoTerrain2D::SafeDownCast | ( | vtkObjectBase * | o | ) | [static] |
Reimplemented from vtkGeoTerrain.
| virtual vtkObjectBase* vtkGeoTerrain2D::NewInstanceInternal | ( | ) | const [protected, virtual] |
Reimplemented from vtkGeoTerrain.
| vtkGeoTerrain2D* vtkGeoTerrain2D::NewInstance | ( | ) | const |
Reimplemented from vtkGeoTerrain.
| virtual void vtkGeoTerrain2D::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.
Reimplemented from vtkGeoTerrain.
| virtual void vtkGeoTerrain2D::SetTextureTolerance | ( | double | ) | [virtual] |
The maximum size of a single texel in pixels. Images will be refined if a texel becomes larger than the tolerance.
| virtual double vtkGeoTerrain2D::GetTextureTolerance | ( | ) | [virtual] |
The maximum size of a single texel in pixels. Images will be refined if a texel becomes larger than the tolerance.
| virtual void vtkGeoTerrain2D::SetLocationTolerance | ( | double | ) | [virtual] |
The maximum allowed deviation of geometry in pixels. Geometry will be refined if the deviation is larger than the tolerance.
| virtual double vtkGeoTerrain2D::GetLocationTolerance | ( | ) | [virtual] |
The maximum allowed deviation of geometry in pixels. Geometry will be refined if the deviation is larger than the tolerance.
| virtual vtkAbstractTransform* vtkGeoTerrain2D::GetTransform | ( | ) | [virtual] |
Return the projection transformation used by this 2D terrain.
| virtual void vtkGeoTerrain2D::InitializeNodeAnalysis | ( | vtkRenderer * | ren | ) | [protected, virtual] |
AddActors() calls this to setup parameters for evaluating nodes.
Reimplemented from vtkGeoTerrain.
| virtual bool vtkGeoTerrain2D::NodeInViewport | ( | vtkGeoTerrainNode * | node | ) | [protected, virtual] |
AddActors() calls this to determine if a node is in the current viewport.
Reimplemented from vtkGeoTerrain.
| virtual int vtkGeoTerrain2D::EvaluateNode | ( | vtkGeoTerrainNode * | node | ) | [protected, virtual] |
AddActors() calls to to evaluate whether a node should be refined (1), coarsened (-1), or remain at the same level (0).
Reimplemented from vtkGeoTerrain.
