id	Name	DataType	PartType	Default	ValueType	Description
	bboxCenter	SFVec3f	initializeOnly	0 0 0		Bounding box center: position offset from origin of local coordinate system.
	bboxSize	SFVec3f	initializeOnly	-1 -1 -1		Bounding box size: automatically calculated, can be specified as an optimization or constraint.
	contourStepSize	SFFloat	inputOutput	0	(-inf, inf)	If contourStepSize is non-zero, then also render all isosurfaces that are multiples of that step size from the initial surface value. For example, with a surface value of 0.25 and a step size of 0.1, then any additional isosurfaces at 0.05, 0.15, 0.35, 0.45, etc shall also be rendered. If contourStepSize is left at the default value of zero, only that single iso value is rendered as a surface.
	dimensions	SFVec3f	inputOutput	1 1 1	[0, inf)	The dimensions field specifies the dimensions of this geometry in the local coordinate space using standard X3D units. It is assumed the volume is centered around the local origin. If the bounding box size is set, it will typically be the same size as the dimensions. If value is (-1,-1,-1) then the internally calculated size will be used.
	gradients	SFNode	inputOutput	NULL	[Texture]	The gradient field may be used to provide explicit per-voxel gradient direction information for determining surface boundaries rather than having it implicitly calculated by the implementation.
	logFeature	MFString	inputOutput		state, child, parent, route, eventIn, eventOut	controls the logging of changes, state: log state changes (e.g. live), child: log child add/remove, parent: log parent add/remove, route: log route add/remove; eventIn: log receiving of events, eventOut: log sending of events: guiView, runtime system should create node-view, guiEdit: runtime system should create node-editeverything: log everything
	metadata	SFNode	inputOutput		MetadataObject	container for payload metadata inside MetadataSet element
	render	SFBool	inputOutput	TRUE		Flag to control the visibility of the node or subtree
	renderSettings	MFNode	inputOutput		[VolumeRenderSettings]	The renderSettings field allows the user to specify specific rendering options to be used on this volumetric object. If the value is not specified by the user, the implementation uses default settings for ray generation, acceleration and normals.
	renderStyle	MFNode	inputOutput		[VolumeRenderStyle]	For each isosurface extracted from the data set, a separate render style may be assigned using the renderStyle node. The rendering styles are taken from the renderStyles field corresponding to the index of the surface value defined. In the case where automatic contours are being extracted using the step size, the explicit surface value shall use the first declared render style, and then render styles are assigned starting from the smallest iso value. In all cases, if there are insufficient render styles defined for the number of isosurfaces to be rendered, the last style shall be used for all surfaces that don't have an explicit style set.
	showBBox	SFBool	inputOutput	FALSE		Show Bounding Box of Subtree.
	sliceThickness	SFVec3f	inputOutput	1 1 1	[0, inf)	The sliceThickness field specifies the slice thickness (if given).
	surfaceTolerance	SFFloat	inputOutput	0	[0, inf)	A surface is defined to be the boundary between different regions of iso values, when that difference is greater than the surfaceTolerance amount.
	surfaceValues	MFFloat	inputOutput		(-inf, inf)	This data representation has one of three possible modes of operation based on the values of the two fields surfaceValues and contourStepSize. If surfaceValues has a single value defined, then render the isosurface that corresponds to that value. If surfaceValues has more than a single value defined then the contourStepSize field is ignored and surfaces corresponding to those nominated values are rendered.
	swapped	SFBool	inputOutput	FALSE		especially 16 bit volumes are sometimes swapped
	voxels	MFNode	inputOutput		[Texture]	The voxels field provides the raw voxel information to be used by the specific rendering styles. The value is any Texture3D type and may have any number of colour components defined. The specific interpretation for the values at each voxel shall be defined by the value of the renderStyle field. If more than one node is defined for this field then each node after the first shall be treated as a mipmap level of monotonically decreasing size. Each level should be half the dimensions of the previous level.
