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");

MRI volume displayed with hot colormap in a figure window with a magenta background

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)

Spiral volume displayed with hot colormap in a figure window with a magenta background

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

R2025a: Removed

setVolume and the images.compatibility.volshow.R2022a.volshow function are removed. Instead, create a Volume object using the volshow function and then set the Data property using dot notation.

Removed	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;

R2023b: Warns

setVolume and the images.compatibility.volshow.R2022a.volshow function issue a warning that they will be removed in a future release.

R2022b: To be removed

setVolume and the images.compatibility.volshow.R2022a.volshow function will be removed in a future release.
