VOL_PAD Function

Returns a 3D volume of data padded on all six sides with zeroes.

result = VOL_PAD(volume, pad_width)

volume On input, volume contains the 3D volume of data to pad.

pad_width The width of the padding around the volume. The size of the resulting volume increases by (2 * pad_width) in all three dimensions.

result The padded volume data.

None.

For best results, process volumes with VOL_PAD before transforming them with VOL_TRANS or slicing them with SLICE_VOL. For more information, see Volume Manipulation in Chapter 7 of the PV-WAVE User's Guide.

See the Examples section in the description of the VOL_MARKER routine.
