VOL_TRANS Function

Standard Library routine that returns a 3D volume of data transformed by a 4-by-4 matrix.

result = VOL_TRANS(volume, dim, trans)

volume The 3D volume of data to transform.

dim A scalar value specifying the x, y, and z dimensions of the transformed volume to return. Normally, dim is the largest of the three dimensions of the original volume. Generally, the original volume should "fit" inside the transformed volume.

trans The 4-by-4 transformation matrix to use for the transformation. trans is often the system viewing transformation matrix !P.T. (For more information, see Geometric Transformations in Chapter 6 of the PV-WAVE User's Guide.

result A 3D volume of data transformed by a 4-by-4 matrix.

None.

The returned volume is scaled into the range of bytes. For best results, the volume to transform should first be processed using the VOL_PAD function. For more information, see Volume Manipulation in Chapter 7 of the PV-WAVE User's Guide.

See the Examples sections in the description of the VOL_MARKER and VOL_REND routines.
