| GetStringName | (Inherited from SoBase.) |
| GetSubSlice(SbBox2i32, Int32, SoBufferObject) | Same as OIV.LDM.Readers.SoVolumeReader.GetSubSlice(OIV.Inventor.SbBox2i32, System.Int32, OIV.Inventor.Generic.SbNativeArray{{System.Byte}}) but using an OIV.Inventor.Devices.SoBufferObject as the target of the data. |
| GetSubSlice(SbBox2i32, Int32, SbNativeArrayByte) | Must copy the rectangular part defined by subSlice of the XY slice sliceNumber to the memory referenced by data. |
| GetTileMinMax | Returns the minimum and maximum data values for the given tile. |
| GetTileSize | Returns tile dimensions in voxels when using data stored in tiles. |
| 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. |
| IsIgnoredFile | Should return true if at least one file has been ignored during reading. |
| IsNotifyEnabled | Notification is the process of telling interested objects that this object has changed. |
| IsSynchronizable | Gets the ScaleViz synchronizable state of this object. |
| ReadTile(Int32, SbBox3i32) | Given an index, reads a tile if the data is organized in tiles (for LDM). |
| ReadTile(Int32, SoBufferObject, SbBox3i32) | Obsolete. Same as OIV.LDM.Readers.SoVolumeReader.ReadTile(System.Int32, OIV.Inventor.Generic.SbNativeArray{{System.Byte}}, OIV.Inventor.SbBox3i32) but using an OIV.Inventor.Devices.SoBufferObject (allocated by LDM) as the target of the data. |
| ReadTile(Int32, SbNativeArrayByte, SbBox3i32) | Obsolete. Given an index, reads a tile if the data is organized in tiles (for LDM). |
| ReadXSliceInTile | Read directly from the data source, an orthoslice on the X axis (Zaxis == 0) inside a tile. |
| ReadXTraceInTile | Read directly from the data source, a trace inside a tile. |
| ReadYSliceInTile | Read directly from the data source, an orthoslice on the Y axis (Zaxis == 1) inside a tile. |
| ReadZSliceInTile | Read directly from the data source, an orthoslice on the Z axis (Zaxis == 2) inside a tile. |
| ReloadTileMinMax | (Inherited from SoVolumeReader.) |
| RestoreAllHandles | Restore resources that were closed by OIV.LDM.Readers.SoVolumeReader.CloseAllHandles(). |
| 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. |
| SetDirectCoordSysAutoDetection | Sets whether or not the reader should automatically try to detect if the coordinate system used is direct or not. |
| SetDirectCoorSys | Specify if the coordinate system used is direct or not. |
| SetFilename | Specifies the path of the file. |
| SetInputDataRange | Requests that the input be converted from the specified range to the range depending on the output data type. |
| SetName | (Inherited from SoBase.) |
| SetOutputDataType | Sets the output data type. |
| SetRectilinearCoordinates | Sets rectilinear coordinates for the data set. |
| SetSynchronizable | Sets this to be a ScaleViz synchronizable object. |

| SetUserData | Obsolete.
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. |
Properties| Name | Description | |
|---|---|---|
 | DataConverted |
true if the data is already organized in tiles for the LDM module.
In other words, all drivers that directly support the GetTile() method should
set DataConverted to true.
If true, VolumeViz will use the ReadTile method and will NOT call GetSubSlice().
(Inherited from SoVolumeReader.) |
| IsDisposable | ISafeDisposable interface implementation.
(Inherited from SoDisposable.) |
| IsRGBA | Returns true if the data set contains RGBA color values. |
| IsThreadSafe | Should return true if the reader is thread safe. |
| UserData |
Gets or sets the user data to be contained by the field container.
(Inherited from SoFieldContainer.) |
RemarksReader for TeraRecon ".vox" data files (vox1999 format).
VOX is a volume interchange format defined by TeraRecon Inc. (www.terarecon.com). The VolumeViz reader can load "Vox1999a" files containing 8- or 16-bit voxels (first volume only).
The following attributes are supported:
"Volume Size" which describes the size of the volume in voxels.
"Voxel Size" which describes the size of voxel data (only 8-bit and 16-bit are supported).
"Endian" which describes the endianness of the data (both little-endian and big-endian modes are supported).
"Volume Scale" which describes the volume of one voxel.
"Volume Position" which describes the origin position of the first voxel.
Since Open Inventor 10.3, the following custom attributes are supported when specified in the "Field" descriptor:
Scale: Define a scaling to apply to data values.
Offset: Define an offset to apply to data values.
If Scale and Offset are specified and are not exactly 1 and 0 respectively:
The actual data value will be : newValue = Scale * fileValue + Offset.
The volume data type is automatically changed to SIGNED_SHORT. This means that, even if the file is specified as unsigned 8 bit, the data will be loaded as signed 16 bit values.
Other attributes have no effect on the reader and loaded data.
