VolumeNode

This abstract node type is the base type for all node types that describe volumetric data to be rendered. It sits at the same level as the polygonal ShapeNode within the scene graph structure, but defines volumetric data rather polygons.

Interface

Filter: X3D only | Avalon only | All
id Name DataType PartType Default ValueType Description
SFVec3f bboxCenter SFVec3f initializeOnly 0 0 0 Bounding box center: position offset from origin of local coordinate system.
SFVec3f bboxSize SFVec3f initializeOnly -1 -1 -1 Bounding box size: automatically calculated, can be specified as an optimization or constraint.
SFVec3f 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.
MFString 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
SFNode metadata SFNode inputOutput MetadataObject container for payload metadata inside MetadataSet element
SFBool render SFBool inputOutput TRUE Flag to control the visibility of the node or subtree
MFNode 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.
SFBool showBBox SFBool inputOutput FALSE Show Bounding Box of Subtree.
SFVec3f sliceThickness SFVec3f inputOutput 1 1 1 [0, inf) The sliceThickness field specifies the slice thickness (if given).
SFBool swapped SFBool inputOutput FALSE especially 16 bit volumes are sometimes swapped
MFNode 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.
