Detailed Description

OpenGL subclass that draws the image to the screen.

This is the concrete implementation of a ray cast image display helper - a helper class responsible for drawing the image to the screen.

See also: vtkGPUVolumeRayCastMapper

Thanks:: Thanks to Michael Granseier for helping to debug this class with respect to maximum memory issues (which must be specified as vtkIdType and not int).

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.

virtual void vtkOpenGLGPUVolumeRayCastMapper::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 vtkGPUVolumeRayCastMapper.

virtual int vtkOpenGLGPUVolumeRayCastMapper::IsRenderSupported	(	vtkRenderWindow *	window,
		vtkVolumeProperty *	property
	)

virtual

Based on hardware and properties, we may or may not be able to render using 3D texture mapping. This indicates if 3D texture mapping is supported by the hardware, and if the other extensions necessary to support the specific properties are available.

virtual void vtkOpenGLGPUVolumeRayCastMapper::ReleaseGraphicsResources ( vtkWindow * window )

virtual

Delete OpenGL objects.

Postcondition: done: this->OpenGLObjectsCreated==0

Reimplemented from vtkGPUVolumeRayCastMapper.

static const char* vtkOpenGLGPUVolumeRayCastMapper::OpenGLErrorMessage ( unsigned int errorCode )
