Detailed Description

This filter composes two or more scalar image volumes.

X3D Interface
	Name	Type	Default value	Description
	method	SFString	"SUM"	The method of composition. Valid values are SUM and SUB.
Derived from ScalarImageFilter
	scalarVolume	MFScalarImageNode	[]	Scalar volume(s) to extract data from.
	vectorVolume	MFVectorImageNode	[]	Vector volume(s) to extract data from.
	pixelComponentType	SFString	""	The type of the target volume. One of SIGNED, UNSIGNED or RATIONAL. If empty the source volume type is used.
	bitsPerPixel	SFInt32	0	The number of bits per voxel for the target volume. If zero the source volume type is used.

Member Data Documentation

H3D::H3DNodeDatabase VHTK::ScalarCompositionFilter::database [static]

X3D node/field database.

Reimplemented from VHTK::ScalarImageFilter.

auto_ptr< H3D::SFString > VHTK::ScalarCompositionFilter::method

The method of composition.

Valid values are

• SUM - voxelwise sum of the individual volumes
• SUB - first scalar volume minus the remaining volumes
