Public propertystyle

Set the draw style used for a volume or mask: .

Public propertyUserData
Gets or sets the user data to be contained by the field container.
(Inherited from SoFieldContainer.)

This node specifies the volume rendering style for a volume or for one of the voxel regions of a volume defined by OIV.VolumeViz.Nodes.SoVolumeMask nodes. The available draw styles are hidden (not rendered), direct volume rendering, isosurface(s) rendering and the boundary surface rendering according to the field. Volume rendering always uses the current transfer function and material in the scene graph. Isosurfaces and boundary surfaces use the current material by default, but can optionally be rendered using materials specified in the OIV.VolumeViz.Nodes.SoVolumeDataDrawStyle.isosurfacesMaterial or OIV.VolumeViz.Nodes.SoVolumeDataDrawStyle.boundaryMaterial fields.


  • Draw style only applies to OIV.VolumeViz.Nodes.SoVolumeRender nodes.

  • See OIV.VolumeViz.Nodes.SoVolumeMask for discussion of how draw styles are associated with mask regions.

  • When not using volume masks, the draw style node must be traversed before the OIV.VolumeViz.Nodes.SoVolumeData node.

  • The MASK_BOUNDARY style is ignored if not using volume masks.

  • The ISOSURFACE style is functionally equivalent to using an OIV.VolumeViz.Nodes.SoVolumeIsosurface node, but provides more options. The benefit of using an OIV.VolumeViz.Nodes.SoVolumeDataDrawStyle is the ability to combine different display styles (e.g. ISOSURFACE and MASK_BOUNDARY). The isosurface displays the boundary between 2 different values, similar to the marching cubes algorithms. In other words, a voxel is part of the isosurface if the ray entry and exit values for the voxel are different and include the specified isosurface value in their range. If you render, for example, the isosurface 100 of a volume data containing the value 100 everywhere, nothing will be rendered.
