X3D Reference



SegmentedVolumeData displays a segmented voxel dataset with different RenderStyle nodes.

The SegmentedVolumeData node belongs to the VolumeRendering component and its container field is children. It is available since X3D version 3.3 or later.



SFVec3f [in, out] dimensions 1 1 1 (0,∞)

Actual-size X-Y-Z dimensions of volume data in local coordinate system.

SFNode [in, out] metadata NULL [X3DMetadataObject]

Metadata are not part of the X3D world and not interpreted by the X3D browser, but they can be accessed via the ECMAScript interface.

MFNode [in, out] renderStyle [ ] [X3DVolumeRenderStyleNode]

Input/Output field renderStyle.

MFBool [in, out] segmentEnabled [ ]

Input/Output field segmentEnabled.

SFNode [in, out] segmentIdentifiers NULL [X3DTexture3DNode]

Input/Output field segmentIdentifiers.

SFNode [in, out] voxels NULL [X3DTexture3DNode]

Input/Output field voxels.

SFVec3f [ ] bboxCenter 0 0 0 (-∞,∞)

Bounding box center: optional hint for position offset from origin of local coordinate system.

SFVec3f [ ] bboxSize -1 -1 -1 [0,∞) or -1 -1 -1

Bounding box size is usually omitted, and can easily be calculated automatically by an X3D player at scene-loading time with minimal computational cost. Bounding box size can also be defined as an optional authoring hint that suggests an optimization or constraint.


Can be useful for collision computations or inverse-kinematics (IK) engines.



  • SegmentedVolumeData can contain a single ComposedTexture3D, ImageTexture3D or PixelTexture3D node with containerField='segmentIdentifiers' and another with containerField='voxels'.
  • SegmentedVolumeData can contain multiple RenderStyle nodes.
