static int vtkUnstructuredGridVolumeRayIntegrator::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 vtkObject.

Reimplemented in vtkUnstructuredGridLinearRayIntegrator, vtkUnstructuredGridPartialPreIntegration, vtkUnstructuredGridPreIntegration, and vtkUnstructuredGridHomogeneousRayIntegrator.

[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 vtkObject.

Reimplemented in vtkUnstructuredGridLinearRayIntegrator, vtkUnstructuredGridPartialPreIntegration, vtkUnstructuredGridPreIntegration, and vtkUnstructuredGridHomogeneousRayIntegrator.

Reimplemented from vtkObject.

Reimplemented in vtkUnstructuredGridLinearRayIntegrator, vtkUnstructuredGridPartialPreIntegration, vtkUnstructuredGridPreIntegration, and vtkUnstructuredGridHomogeneousRayIntegrator.

virtual void vtkUnstructuredGridVolumeRayIntegrator::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 vtkObject.

Reimplemented in vtkUnstructuredGridLinearRayIntegrator, vtkUnstructuredGridPartialPreIntegration, vtkUnstructuredGridPreIntegration, and vtkUnstructuredGridHomogeneousRayIntegrator.

virtual void vtkUnstructuredGridVolumeRayIntegrator::Initialize	(	vtkVolume *	volume,
		vtkDataArray *	scalars
	)		[pure virtual]

Set up the integrator with the given properties and scalars.

Implemented in vtkUnstructuredGridLinearRayIntegrator, vtkUnstructuredGridPartialPreIntegration, vtkUnstructuredGridPreIntegration, and vtkUnstructuredGridHomogeneousRayIntegrator.

virtual void vtkUnstructuredGridVolumeRayIntegrator::Integrate	(	vtkDoubleArray *	intersectionLengths,
		vtkDataArray *	nearIntersections,
		vtkDataArray *	farIntersections,
		float	color[4]
	)		[pure virtual]

Given a set of intersections (defined by the three arrays), compute the peicewise integration of the array in front to back order. /c intersectionLengths holds the lengths of each peicewise segment. /c nearIntersections and /c farIntersections hold the scalar values at the front and back of each segment. /c color should contain the RGBA value of the volume in front of the segments passed in, and the result will be placed back into /c color.

Implemented in vtkUnstructuredGridLinearRayIntegrator, vtkUnstructuredGridPartialPreIntegration, vtkUnstructuredGridPreIntegration, and vtkUnstructuredGridHomogeneousRayIntegrator.
