Detailed Description

VolumeViz Generic file reader.

Reader for volume data files containing only binary data values or else a fixed size header followed by binary data values.

Many volume data formats that are not directly supported by VolumeViz can be loaded using this reader.

The application must know:

Member Function Documentation

static SoType SoVRGenericFileReader::getClassTypeId (  )  [static]

Returns the type identifier for this class.

Reimplemented from SoVolumeReader.

virtual ReadError SoVRGenericFileReader::getDataChar ( SbBox3f size,
SoDataSet::DataType type,
SbVec3i32 dim 
) [inline, virtual]

Gets the characteristics (file header) of the data volume.

See SoVolumeData. size is the size of the actual volume. type is the type of the data. dim is the dimension of the data.

Implements SoVolumeReader.

virtual SoVolumeReader::ReaderType SoVRGenericFileReader::getReaderType (  )  [inline, virtual]

Returns the reader type.

Reimplemented from SoVolumeReader.

virtual void SoVRGenericFileReader::getSubSlice ( const SbBox2i32 subSlice,
int  sliceNumber,
void *  data 
) [virtual]

New method required by VolumeViz 3.0 when using large volume support.

Must copy a rectangular part of an XY slice to the memory specified by data. Slices will not always be read sequentially.

Implements SoVolumeReader.

virtual SoType SoVRGenericFileReader::getTypeId (  )  const [virtual]

Returns the type identifier for this specific instance.

Reimplemented from SoVolumeReader.

SoDEPRECATED void SoVRGenericFileReader::setDataChar ( SbBox3f size,
SoDataSet::DataType type,
SbVec3s smalldim,
int  headerSize = 0 
) [inline]
void SoVRGenericFileReader::setDataChar ( const SbBox3f size,
const SoDataSet::DataType type,
const SbVec3i32 dim,
int  headerSize = 0 
) [inline]

Since the format is raw data, it is necessary to specify the dimension and data size of the volume.

You can also specify a header size to add support for your own file format.
