setVolume

(To be removed) Set new volume in volshow object

setVolume will be removed in a future release. Set the Data property of a Volume object instead. For more information, see Version History.

Syntax

setVolume(hVol,V)

Description

setVolume(hVol,V) updates the volshow object hVol with a new volume V. setVolume preserves the current viewpoint and other visualization settings remain unchanged.

Examples

Change Volume in volshow Object

Load a volume.

load mri
V = squeeze(D);

Display the volume in a volshow object using the images.compatibility.volshow.R2022a.volshow function. Specify a nondefault colormap and background color.

vol = images.compatibility.volshow.R2022a.volshow(V, ...
    "Colormap",hot(256),"BackgroundColor","magenta");

Load a new volume, then display that volume in the existing volshow object. Note that setVolume preserves the colormap and the background color.

load spiralVol
setVolume(vol,spiralVol)

Input Arguments

hVol — Volume visualization

volshow object

Volume visualization, specified as a volshow object. You can create a volshow object using the images.compatibility.volshow.R2022a.volshow function.

V — Volumetric data

3-D grayscale volume

Volumetric data, specified as a 3-D grayscale volume.

Version History

Introduced in R2019a

R2022b: setVolume will be removed

setVolume and the images.compatibility.volshow.R2022a.volshow function will be removed in a future release. Instead, create a Volume object using the volshow function and then set the Data property using dot notation.

Discouraged Usage	Recommended Replacement
This example uses the setVolume function to change the displayed volume data. load mri V = squeeze(D); vol = images.compatibility.volshow.R2022a.volshow(V); load spiralVol setVolume(vol,spiralVol);	Here is equivalent code, creating a Volume object then changing the displayed data by setting the Data property. load mri V = squeeze(D); vol = volshow(V); load spiralVol vol.Data = spiralVol;
