SafeDisposable

public class SoVRGenericFileReader
extends SoVolumeReader

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:

• The size of the header, if any, in bytes,
• The dimensions of the volume, and
• The data type (char, unsigned int, ...)

Steps to follow:

• Create an instance of SoVRGenericFileReader.
  • Call setFilename() to specify the filename.
  • Call setDataChar() to specify the dimensions, data type and header size.
• Create an instance of SoVolumeData.
  • Call setReader() with the instance of SoVRGenericFileReader.

void	setDataChar(SbBox3f size, SoDataSet.DataTypes type, SbVec3i32 dim)	Calls setDataChar(size, type, dim, (int)0).
void	setDataChar(SbBox3f size, SoDataSet.DataTypes type, SbVec3i32 dim, int headerSize)	Since the format is raw data, it is necessary to specify the dimension and data size of the volume.

Method Detail

setDataChar

public void setDataChar(SbBox3f size,
                        SoDataSet.DataTypes type,
                        SbVec3i32 dim)

Calls setDataChar(size, type, dim, (int)0).

setDataChar

public void setDataChar(SbBox3f size,
                        SoDataSet.DataTypes type,
                        SbVec3i32 dim,
                        int headerSize)

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.
