Detailed Description
Render one orthogonal slice of the volume data.
Insert a node of this type after an SoVolumeData node in the scene graph to render a single, axis-aligned slice from the full volume data set.
Here is a simple example, in the form of an iv-file:
#Inventor V2.1 ascii
SoVolumeData { fileName 'ENGINE.VOL' }
SoTransferFunction { predefColorMap TEMPERATURE }
SoOrthoSlice { sliceNumber 0 }
Translation { translation 5 0 0 }
SoOrthoSlice { sliceNumber 10 }Which will produce something like this when loaded into an examinerviewer:

Member Data Documentation
SoSFUInt32 SoOrthoSlice::sliceNumber
Decides where the slice will be made through the volume.
Default value is 0.
SoSFEnum SoOrthoSlice::axis
Decides which plane the orthonormal slice will show. The plane will be the one perpendicular to the axis, i.e if this field is set to SoOrthoSlice::Z, the slice will lay in the X-Y plane.
Default value is SoOrthoSlice::Z.
SoSFEnum SoOrthoSlice::alphaUse
Decides how to handle the alpha values of the slice. If set to SoOrthoSlice::ALPHA_AS_IS, slice will be rendered as a regular texture. When set to SoOrthoSlice::ALPHA_BINARY, all texels with alpha != 0 will become opaque. If set to SoOrthoSlice::ALPHA_OPAQUE, all texels will be opaque, independent of original alpha value.
Default value is SoOrthoSlice::ALPHA_BINARY.
