SLICE_VOL Function

Returns a 2D array containing a slice from a 3D volumetric array.

Usage

result = SLICE_VOL(volume, dim, cut_plane)

Input Parameters

The 3D volume of data to slice.

TIP: For better results, first use VOL_PAD to preprocess the volume.

dim

The x and y dimensions of the slice to return. Larger values for dim increase the slice resolution and execution time. dim is typically the largest of the three dimensions of volume.

cut_plane A (3, 2) array defining the slicing plane. The elements in this (3, 2) array are interpreted as follows:


cut_plane(0, 0)	The plane's angle of rotation about the x-axis.
cut_plane(1, 0)	The plane's angle of rotation about the y-axis.
cut_plane(2, 0)	Ignored.
cut_plane(0, 1)	The x-coordinate of the center of the plane.
cut_plane(1, 1)	The y-coordinate of the center of the plane.
cut_plane(2, 1)	The z-coordinate of the center of the plane.

NOTE: The slicing plane is rotated first about the y-axis, and then about the x-axis.

Returned Value

A 2D array containing a slice from a 3D volumetric array.

Keywords

If present and nonzero, cut_plane(0:1,0) is assumed to be in degrees.

Discussion

SLICE_VOL extracts a planar oblique slice from a volumetric (3D) array. The slicing plane is defined by the center point (X, Y, and Z), and the rotations about the y- and x-axes. You can interactively define the slicing plane by calling the VIEWER procedure.

For best results, process volumes with VOL_PAD before slicing them with SLICE_VOL.

Example

For demonstrations of the SLICE_VOL procedure, use the Medical Imaging and CFD/Aerospace buttons on the PV-WAVE Demonstration Gallery.

To run the Gallery, enter wave_gallery at the WAVE prompt.
