(Inherited from SoVolumeReader.)
Public methodReadTile(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.)
Public methodSet

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.)
Public methodSetChannelSelection

Selects channels to be used for data rendering.

Public methodSetDirectCoordSysAutoDetection
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.)
Public methodSetDirectCoorSys
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.)
Public methodSetDirectory

Specify a directory containing image files to load (jpg, png, tif,...).

Public methodSetFilename
Specifies the path of the file. Returns 0 for success. Any other return value indicates failure.
(Inherited from SoVolumeReader.)
Public methodSetName (Inherited from SoBase.)
Public methodSetOutputDataType
Sets the output data type. Returns FALSE if the reader does not support this feature.
(Inherited from SoVolumeReader.)
Public methodSetSize

Defines the bounding box size in physical units of the data set.

Public methodSetSynchronizable

Sets this to be a ScaleViz synchronizable object.

(Inherited from SoBase.)
Public methodSetToDefaults

Sets all fields in this object to their default values.

(Inherited from SoFieldContainer.)
Public methodSetUserData
Stores the userData (for example the filename string) in the m_data protected variable.
(Inherited from SoVolumeReader.)
Public methodToString
Converts this SoBase structure to a human readable string.
(Inherited from SoBase.)
Public methodTouch

Marks an instance as modified, simulating a change to it.

(Inherited from SoBase.)

Public propertyIsDisposable
ISafeDisposable interface implementation.
(Inherited from SoDisposable.)
Public propertyIsThreadSafe
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.)
Public propertyUserData
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

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.
