Detailed Description

performs piecewise constant ray integration.

vtkUnstructuredGridHomogeneousRayIntegrator performs homogeneous ray integration. This is a good method to use when volume rendering scalars that are defined on cells.

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.

void vtkUnstructuredGridHomogeneousRayIntegrator::Initialize	(	vtkVolume *	volume,
		vtkDataArray *	scalars
	)

overridevirtual

Set up the integrator with the given properties and scalars.

Implements vtkUnstructuredGridVolumeRayIntegrator.

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

overridevirtual

Given a set of intersections (defined by the three arrays), compute the piecewise integration of the array in front to back order.

/c intersectionLengths holds the lengths of each piecewise 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.

Implements vtkUnstructuredGridVolumeRayIntegrator.

For quick lookup, the transfer function is sampled into a table.

This parameter sets how big of a table to use. By default, 1024 entries are used.
