	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	FieldsAreEqual	Returns true if this object's fields are exactly equal to fc's fields. (Inherited from SoFieldContainer.)
	Get	Returns the values of the fields of this object in the Open Inventor ASCII file format in the given string. (Inherited from SoFieldContainer.)
	GetAllFields	Returns a list of fields, including the eventIn's and eventOut's. (Inherited from SoFieldContainer.)
	GetBorderFlag	Returns border flag if stored in file. (Inherited from SoVolumeReader.)
	GetConfiguredWriter	Returns a writer that correspond to this reader (same format, same parameters, etc...). (Inherited from SoVolumeReader.)

	GetField	Returns a the field of this object whose name is fieldName. (Inherited from SoFieldContainer.)
	GetFieldName	Returns the name of the given field in the fieldName argument. (Inherited from SoFieldContainer.)
	GetFields	Appends references to all of this object's fields to resultList, and returns the number of fields appended. (Inherited from SoFieldContainer.)
	GetHashCode	Overrides GetHashCode(). (Inherited from SoNetBase.)
	GetHistogram	Returns histogram if stored in file. (Inherited from SoVolumeReader.)
	GetMinMax(Double, Double)	Returns min max if stored in file for float data type (Inherited from SoVolumeReader.)

	GetStringName	(Inherited from SoBase.)
	GetSubSlice	Method required by VolumeViz 3.0. Must copy the rectangular part defined by subSlice of the XY slice sliceNumber to the memory pointed to by data. Slices will not always be read sequentially. (Inherited from SoVolumeReader.)
	GetTileMinMax	Returns the minimum and maximum data values for the given tile. Used only if data is organized for the LDM module. It allows to profit of optimizations such as SoLDMGlobalResourceParameters.setIgnoreFullyTransparentTiles(). Default implementation return new SbVec2d(System.Double.MaxValue, -System.Double.MaxValue)) (Inherited from SoVolumeReader.)
	GetTileSize	Returns tile size if using data stored in tiles. Return FALSE if data is not stored in tiles. (Inherited from SoVolumeReader.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	HasDefaultValues	Returns true if all of the object's fields have their default values. (Inherited from SoFieldContainer.)

	IsSynchronizable	Gets the ScaleViz synchronizable state of this object. (Inherited from SoBase.)
	ReadTile(Int32, SbBox3i32)	Given an index, reads a tile if the data is organized in tiles (for LDM). (Inherited from SoVolumeReader.)
	ReadTile(Int32, SbNativeArrayByte, SbBox3i32)	Obsolete. Given an index, reads a tile if the data is organized in tiles (for LDM). In the default LDM architecture, the LDM data is based on an octree topology (see SoVRLdmFileReader). The index passed is 0 for the tile of lowest resolution representing the entire volume (octree root node). The index increments linearly going down through the octree. (Inherited from SoVolumeReader.)
	Set	Sets one or more fields in this object to the values specified in the given string, which should be a string in the Open Inventor file format. (Inherited from SoFieldContainer.)
	SetChannelSelection	Selects channels to be used for data rendering.
	SetDirectCoordSysAutoDetection	Sets whether or not the reader should automatically try to detect if the coordinate system used is direct or not. The function will return FALSE if the feature is not supported by the current reader. Default is false. (Inherited from SoVolumeReader.)
	SetDirectCoorSys	Specify if the coordinate system used is direct or not. The function will return FALSE if the feature is not supported by the current reader. Default is false. (Inherited from SoVolumeReader.)
	SetDirectory	Specify a directory containing image files to load (jpg, png, tif,...).
	SetFilename	Specifies the path of the file. Returns 0 for success. Any other return value indicates failure. (Inherited from SoVolumeReader.)
	SetName	(Inherited from SoBase.)
	SetOutputDataType	Sets the output data type. Returns FALSE if the reader does not support this feature. (Inherited from SoVolumeReader.)
	SetSize	Defines the bounding box size in physical units of the data set.
	SetSynchronizable	Sets this to be a ScaleViz synchronizable object. (Inherited from SoBase.)
	SetToDefaults	Sets all fields in this object to their default values. (Inherited from SoFieldContainer.)
	SetUserData	Stores the userData (for example the filename string) in the m_data protected variable. (Inherited from SoVolumeReader.)
	ToString	Converts this SoBase structure to a human readable string. (Inherited from SoBase.)
	Touch	Marks an instance as modified, simulating a change to it. (Inherited from SoBase.)

Properties

	Name	Description
	DataConverted	The returned boolean indicates if the data is already organized for the LDM module. If TRUE, VolumeViz will use the readTile method. (Inherited from SoVolumeReader.)
	IsDisposable	ISafeDisposable interface implementation. (Inherited from SoDisposable.)
	IsThreadSafe	Let the system know if the reader is thread safe or not. this function is called by VolumeViz when using the multiIO mode. (Inherited from SoVolumeReader.)
	UserData	Gets or sets the user data to be contained by the field container. (Inherited from SoFieldContainer.)

Remarks

Reader for a volume defined by a "stack" of images.

A raster stack is a list of raster images (that is, containing pixels, not vector graphics) of the same size so as to create a voxel volume. This reader uses a descriptive file (.lst) including a header and a list of all the raster image filenames. The file is structured as follows:

 Parameters {
  Raw 0
  Dims 2048 2048 100
  Size 10.000000 10.000000 10.000000 1250.000000 1250.000000 500.000000
  Channel 2
}

C:/tmp/tiff/img00000.tiff
C:/tmp/tiff/img00001.tiff
C:/tmp/tiff/img00002.tiff
C:/tmp/tiff/img00003.tiff
C:/tmp/tiff/img00004.tiff
....

 Parameters {
  Raw 1
  Endianess 1
  HeaderLength 256
  PrimType 0
  Binary 0
  Dims 1024 1024 300
  Size 50.000000 50.000000 50.000000 1050.000000 1050.000000 250.000000
  Channel 1
}

img00001.raw
img00002.raw
img00003.raw

....

Header Description

Raw: 0 (formatted data file), 1 (raw data file).
Endianess: 0 (little endian), 1 (big endian) (for raw data only).
HeaderLength: length of header in characters/bytes (for raw data only).
PrimType: See OIV.LDM.Nodes.SoDataSet.DataTypes (for raw data only).
Binary: 0 (ASCII), 1 (binary) (for raw data only).
Dims: height, width, depth in pixels of the stack.
Size: Xmin Ymin Zmin Xmax Ymax Zmax, bounding box of the data set.
Channel: See OIV.VolumeViz.Readers.SoVRRasterStackReader.ChannelSelections.

Images in the list can be of different formats (uses all files formats supported by Open Inventor). VolumeViz can load image data in most common image formats including BMP, DDS, GIF, JPEG, JPEG2000, PNG and TIFF.

If images are different sizes, RD_UNSUPPORTED_DATA_TYPE_ERROR is returned by ().

The file path can be relative or absolute.

It is mandatory to have a line break after each property and/or filename otherwise VolumeViz could be unable to read the file properly.
