class SoOrthoSliceP

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.

SoSFNode SoOrthoSlice::alternateRep

NOTE: support for this field not yet implemented in SIM Voleon.
