Header File Format (hdr)Example Header File: "volume.hdr"
The header volume file format allows the user to load a raw binary volume file into Mesh Viewer. For example, given a raw volume file called "volume.raw" with resolution 256 x 256 x 256, a corresponding "volume.hdr" file can be made as follows.
# Comment Line Datafile: volume.raw Resolution: 256 256 256 Spacing: 0.01 0.01 0.01 VoxelType: SCALAR | RGB | RGBA | MULTI N FieldType: BYTE | SHORT | INT | FLOAT MinVal: Float.MIN_VALUE MaxVal: Float.MAX_VALUE ByteOrder: MSB | LSB CoordSystem: LEFT_HANDED | RIGHT_HANDED SkipBytes: 18
Datafile: The name of the raw volume data file.
Resolution: The size of the volume dataset in the X, Y and Z dimensions.
Spacing: The distance between voxels in the X, Y and Z dimensions.
VoxelType: The number of fields associated with each voxel. Voxels typically contain SCALAR, RGB and RGBA fields. Voxels can also store an arbitrary number of fields specified by MULTI.
FieldType: The data type for each field specified as a Byte, Short, Integer and Floating-point value.
MinVal and MaxVal: The expected minimum and maximum field values.
ByteOrder: The byte ordering of each field as MSB or LSB.
CoordSystem: The X-Y-Z coordinate system is LEFT_HANDED or RIGHT_HANDED. RIGHT_HANDED is the default coordinate system.
SkipBytes: The number of bytes to skip at the beginning of the raw volume file.
