Property Value

Use this field if your volume data is already loaded into memory in a contiguous block of memory. Otherwise use the fileName field or the OIV.LDM.Nodes.SoDataSet.SetReader(OIV.LDM.Readers.SoVolumeReader, System.Boolean) method.

The numSigBits parameter of OIV.Inventor.Fields.SoSFArray3D.SetValue(OIV.Inventor.SbVec3i32, OIV.Inventor.SbDataType, System.UInt32, OIV.Inventor.Generic.SbNativeArray{{System.Byte}}, OIV.Inventor.Fields.SoSFArray.CopyPolicies) indicates the number of bits really used for each value. If it equals 0, that means to use all bits, e.g., 8 bits if type = UNSIGNED_BYTE, 16 bits if type = UNSIGNED_SHORT and so on. This parameter is useful particularly when textures are loaded in paletted mode. Currently most hardware supports only 8 bits, so VolumeViz must discard the least significant bits. For example if type is UNSIGNED_SHORT, by default in paletted mode VolumeViz will discard the lowest 8 bits. If you specify numSigBits = 10, VolumeViz will discard only the lowest 2 bits.

Calling OIV.Inventor.Fields.SoSFArray3D.SetValue(OIV.Inventor.SbVec3i32, OIV.Inventor.SbDataType, System.UInt32, OIV.Inventor.Generic.SbNativeArray{{System.Byte}}, OIV.Inventor.Fields.SoSFArray.CopyPolicies) with a CopyPolicy set to NO_COPY is equivalent to calling the deprecated SoVolumeData.setValue method.

Volume reader: Note that when a file format reader or custom volume reader is currently being used, setting the data field will automatically replace the current volume reader. Subsequent calls to () will return an OIV.VolumeViz.Readers.SoVRMemoryReader.

Note
Field available since Open Inventor 7.1
