Member Function Documentation

vtkOpenGLRenderer* vtkOpenGLRenderer::New (    )  [static]

Create a vtkRenderer with a black background, a white ambient light, two-sided lighting turned on, a viewport of (0,0,1,1), and backface culling turned off. Reimplemented from vtkRenderer.

virtual const char* vtkOpenGLRenderer::GetClassName (    )  [virtual]

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkRenderer.

int vtkOpenGLRenderer::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 vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkRenderer.

virtual int vtkOpenGLRenderer::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 vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkRenderer.

vtkOpenGLRenderer* vtkOpenGLRenderer::SafeDownCast (  vtkObject *    o )  [static]

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkRenderer.

void vtkOpenGLRenderer::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 vtkRenderer.

void vtkOpenGLRenderer::DeviceRender (  void    )  [virtual]

Concrete open gl render method. Reimplemented from vtkRenderer.

void vtkOpenGLRenderer::ClearLights (  void    )

Internal method temporarily removes lights before reloading them into graphics pipeline.

void vtkOpenGLRenderer::Clear (  void    )  [virtual]

Clear the image to the background color. Reimplemented from vtkRenderer.

int vtkOpenGLRenderer::UpdateLights (  void    )  [virtual]

Ask lights to load themselves into graphics pipeline. Reimplemented from vtkRenderer.

virtual void vtkOpenGLRenderer::DevicePickRender (    )  [protected, virtual]

Reimplemented from vtkViewport.

virtual void vtkOpenGLRenderer::StartPick (  unsigned int    pickFromSize )  [protected, virtual]

Reimplemented from vtkViewport.

virtual void vtkOpenGLRenderer::UpdatePickId (    )  [protected, virtual]

Reimplemented from vtkViewport.

virtual void vtkOpenGLRenderer::DonePick (    )  [protected, virtual]

Reimplemented from vtkViewport.

virtual unsigned int vtkOpenGLRenderer::GetPickedId (    )  [protected, virtual]

Reimplemented from vtkViewport.

virtual float vtkOpenGLRenderer::GetPickedZ (    )  [protected, virtual]

Return the Z value for the last picked Prop. Reimplemented from vtkViewport.
