Detailed Description

performs peicewise constant ray integration.

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

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.

◆ PrintSelf()

virtual void vtkUnstructuredGridHomogeneousRayIntegrator::PrintSelf	(	ostream &	os,

	)

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.

◆ Initialize()

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

virtual

Set up the integrator with the given properties and scalars.

Implements vtkUnstructuredGridVolumeRayIntegrator.

◆ Integrate()

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

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.

Implements vtkUnstructuredGridVolumeRayIntegrator.

◆ SetTransferFunctionTableSize()

virtual void vtkUnstructuredGridHomogeneousRayIntegrator::SetTransferFunctionTableSize ( int )

virtual

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.
