public virtual int GetNumSignificantBits()

Public Overridable Function GetNumSignificantBits As Integer

public:
virtual int GetNumSignificantBits()

abstract GetNumSignificantBits : unit -> int 
override GetNumSignificantBits : unit -> int 

Return Value

It returns the number of significant bits of the volume data.

If it is not implemented, the default return value is 0, meaning the number of bits depends on the data type. See the last parameter of SoVolumeData.setVolumeData(). This method is called immediately after OIV.LDM.Readers.SoVolumeReader.GetDataChar(OIV.Inventor.SbBox3f@, OIV.LDM.Nodes.SoDataSet.DataTypes@, OIV.Inventor.SbVec3i32@). For float data type, number of bits is forced to 32.
